THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Preparing to Install the Router
This chapter describes important information to consider before you begin to install a Cisco 2600 series router, and includes the following sections:

• Safety Recommendations, page 2-1

• General Site Requirements, page 2-3

• Preparing to Connect to a Network, page 2-5

After you have completed this chapter, proceed to Chapter 3, “Installing the Router” for installation instructions.

Safety RecommendationsFollow these guidelines to ensure general safety:

• Keep the chassis area clear and dust-free during and after installation.

• Put the removed chassis cover in a safe place.

• Keep tools away from walk areas where you and others could fall over them.

• Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves.

• Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.

• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Safety WarningsSafety warnings appear throughout this publication in procedures that, if performed incorrectly, might harm you. A warning symbol precedes each warning statement.

Warning Read the installation instructions before you connect the system to its power source. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.


Chapter 2 Preparing to Install the RouterSafety Recommendations

Warning Only trained and qualified personnel should be allowed to install or replace this equipment. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Maintaining Safety with ElectricityFollow these guidelines when working on equipment powered by electricity:

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or can weld the metal object to the terminals. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Warning Incorrect connection of this or connected equipment to a general purpose outlet could result in a hazardous situation. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.


OL-2171-02

Chapter 2 Preparing to Install the RouterGeneral Site Requirements

Warning This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.

• Locate the emergency power off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn OFF the power.

• Power OFF the router and unplug the power cord before doing the following:

– Installing or removing a chassis

– Working near power supplies

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit. Always check.

If an electrical accident occurs, proceed as follows:

• Use caution; do not become a victim yourself.

• Turn OFF power to the system.

• If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

• Determine if the victim needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge DamageElectrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic components are improperly handled and can result in complete or intermittent failures.

Always follow ESD-prevention procedures when removing and replacing components. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must be used effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 to 10 megohms (Mohm).

General Site RequirementsThis section describes the requirements your site must meet for safe installation and operation of your system. Ensure that your site is properly prepared before beginning installation.


OL-2171-02

Chapter 2 Preparing to Install the RouterGeneral Site Requirements

Site EnvironmentThe router can be placed on a desktop or mounted in a rack. Single rack-unit (1RU) routers can also be mounted on a wall. The location of the chassis and the layout of your equipment rack or wiring room are extremely important for proper system operation. Placing equipment too close together, inadequate ventilation, and inaccessible panels can make system maintenance difficult or cause system malfunctions and shutdowns.

When planning your site layout and equipment locations, remember the precautions described in the next section, “Preventive Site Configuration.” If you are experiencing shutdowns or unusually high errors with your existing equipment, these precautions might help you isolate the cause of failures and prevent future problems.

Preventive Site ConfigurationThe following precautions will help you plan an acceptable operating environment for your router and help you avoid environmentally-caused equipment failures:

• Ensure that the room in which you operate your system has adequate air circulation. Electrical equipment generates heat. Ambient air temperature might not be able to cool equipment to acceptable operating temperatures without adequate circulation.

• Always follow the ESD-prevention procedures described in the “Preventing Electrostatic Discharge Damage” section on page 23 to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

• Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively inside it. An open chassis allows air leaks, which might interrupt and redirect the flow of cooling air from internal components.

Configuring Equipment Racks

The following information will help you plan an acceptable equipment rack configuration:

• Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.

• When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or the exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated all the way into the rack.

• In an enclosed rack with a ventilation fan in the top, excessive heat generated by equipment near the bottom of the rack can be drawn upward and into the intake ports of the equipment above it in the rack. Ensure that you provide adequate ventilation for equipment at the bottom of the rack.

• Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different arrangements.

Power Supply Considerations

Check the power at your site to ensure that you are receiving “clean” power (free of spikes and noise). Install a power conditioner if necessary.


OL-2171-02

Chapter 2 Preparing to Install the RouterPreparing to Connect to a Network

Warning The device is designed to work with TN power systems. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

The router power supply includes the following features:

• Autoselects either 110V or 220V operation.

• All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation for the unit.)

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Preparing to Connect to a NetworkWhen setting up your router, consider distance limitations and potential electromagnetic interference (EMI) as defined by the applicable local and international regulations.

Network connection considerations are provided for several types of network interfaces and are described in the following sections:

• Ethernet Connections, page 2-5

• Token Ring Connections, page 2-6

• Serial Connections, page 2-7

• ISDN BRI Connections, page 2-12

• 56K/Switched-56-kbps DSU/CSU Connections, page 2-13

Warning The Ethernet 10BASE-T, Token Ring, console, and auxiliary ports contain safety extra-low voltage (SELV) circuits. Avoid connecting SELV circuits to TNV circuits. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Ethernet ConnectionsThe IEEE has established Ethernet as standard IEEE 802.3. The most common Ethernet implementations are as follows:


OL-2171-02


• 100BASE-T—2-pair Category 5 or unshielded twisted-pair (UTP) straight-through RJ-45 cable.

• 10BASE2—Ethernet on thin coaxial cable, also known as thin Ethernet. The maximum segment distance is 607 feet (186 meters).

• 10BASE5—Ethernet on thick coaxial cable, also known as thick Ethernet. The maximum segment distance is 1,640 feet (500 meters).

• 10BASE-T—Ethernet on UTP cable. The maximum segment distance is 328 feet (100 meters). UTP cables look like the wiring used for ordinary telephones; however, UTP cables meet certain electrical standards that telephone cables do not meet.

Table 2-1 lists the router models described in this guide and summarizes the LAN interfaces supported on each model.

Token Ring ConnectionsThe Cisco 2612 provides both an Ethernet interface and a Token Ring shielded UTP interface. The Cisco 2613 provides a single Token Ring interface. (See Table 2-1.)

The IEEE has established Token Ring as standard IEEE 802.5. Specifications indicate a maximum segment distance of 328 feet (100 meters) for UTP cabling.

Note To ensure agency compliance with FCC Class B electromagnetic emissions requirements (EMI), make sure that you use the shielded RJ-45 Token Ring cable when connecting your router to your Token Ring network.

Token Ring can operate at two different ring speeds: 4 and 16 Mbps. All devices on the Token Ring must use the same operating speed.

Use the provided Token Ring cable to connect the router to a switch. Refer to the section “Token Ring Port Pinouts” in the Cisco Modular Access Router Cabling Specifications online document for the Token Ring port pinouts. This document is on the Documentation CD-ROM that accompanied your router package, and on Cisco.com.

Serial ConnectionsSerial connections are provided by WAN interface cards and network modules. The WAN interface cards can be installed in either slot of the 2-slot chassis; the network module can be installed in the Cisco 2600 series single network module slot. For more information on WAN interface cards, refer to the Cisco WAN Interface Cards Hardware Installation Guide. For more information on network modules, refer to the Network Modules Hardware Installation Guide. Both of these documents are on the Documentation CD-ROM that accompanied your router package, and on Cisco.com.

• For information about installing WAN interface cards, refer to the Cisco WAN Interface Cards Hardware Installation Guide, located at: Cisco Product Documentation > Access Servers and Access Routers > Modular Access Routers Cisco 2600 Routers > Hardware installation documents for Cisco 2600 series > Interface card installation

• For information about installing network modules, refer to the Cisco Network Modules Hardware Installation Guide, located at: Cisco Product Documentation > Access Servers and Access Routers > Modular Access Routers Cisco 2600 Routers > Hardware installation documents for Cisco 2600 series > Network module (netmod) installation

Before you connect a device to a serial port, you need to know the following:

• Type of device, data terminal equipment (DTE) or data communications equipment (DCE), you are connecting to the synchronous serial interface

• Type of connector, male or female, required to connect to the device

• Signaling standard required by the device

Configuring Serial Connections

The serial ports on the asynchronous/synchronous serial network modules and the serial WAN interface card use DB-60 connectors. (See Figure 2-1 through Figure 2-6.) Serial ports can be configured as DTE or DCE, depending on the serial cable used.

Serial DTE or DCE Devices

A device that communicates over a synchronous serial interface is either a DTE or DCE device. A DCE device provides a clock signal that paces the communications between the device and the router. A DTE device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation that accompanied the device should indicate whether it is a DTE or DCE device. (Some devices have a jumper to select either DTE or DCE mode.) If you cannot determine the device type in the documentation, see Table 2-2 to help you select the proper device type.


OL-2171-02


Signaling Standards Supported

The synchronous serial ports available for the router support the following signaling standards: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a Cisco DB-60 shielded serial transition cable that has the appropriate connector for the standard you specify. The documentation for the device you want to connect should indicate the standard used for that device. The router end of the shielded serial transition cable has a DB-60 connector, which connects to the DB-60 port on a serial WAN interface card. The other end of the serial transition cable is available with a connector appropriate for the standard you specify.

The synchronous serial port can be configured as DTE or DCE depending on the attached cable (except EIA-530, which is DTE only). To order a shielded cable, contact customer service. See the “Obtaining Technical Assistance” section on page xiii.

Note All serial ports configured as DTE require external clocking from a CSU/DSU or other DCE device.

Although manufacturing your own serial cables is not recommended (because of the small size of the pins on the DB-60 serial connector), cable pinouts are provided in the Cisco Modular Access Router Cabling Specifications document on Cisco.com and the Documentation CD-ROM that accompanied your router.

Distance Limitations

Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the greater the distance. All serial signals are subject to distance limits, beyond which a signal significantly degrades or is completely lost.

Note Only the serial WAN interface card supports bit rates above 128 Kbps.

Table 2-3 lists the recommended maximum speeds and distances for each serial interface type; however, you might get good results at speeds and distances greater than those listed, if you understand the electrical problems that might arise and can compensate for them. For instance, the recommended maximum rate for V.35 is 2 Mbps, but 4 Mbps is commonly used.

OL-2171-02


Balanced drivers allow EIA/TIA-449 signals to travel greater distances than EIA/TIA-232 signals. The recommended distance limits for EIA/TIA-449 shown in Table 2-3 are also valid for V.35, X.21, and EIA-530. Typically, EIA/TIA-449 and EIA-530 can support 2-Mbps rates, and V.35 can support 4-Mbps rates.

Asynchronous/Synchronous Serial Module Baud Rates

The following baud-rate limitations apply to the slow-speed serial interfaces found in the asynchronous/synchronous serial modules:

• Asynchronous interface—Maximum baud rate is 115.2 kbps.

• Synchronous interface—Maximum baud rate is 128-kbps full duplex.

EIA/TIA-232 Connections

EIA/TIA-232 supports unbalanced circuits at signal speeds up to 64 kbps. The network end of the adapter cable is a standard 25-pin D-shell connector known as a DB-25. (See Figure 2-1.) The router console and auxiliary ports also use EIA/TIA-232 connections; however, the serial module ports support synchronous connections, and the console and auxiliary ports support asynchronous connections.

Figure 2-1 EIA/TIA-232 Adapter Cable Connectors, Network End

EIA/TIA-449 Connections

EIA/TIA-449, which supports balanced (EIA/TIA-422) and unbalanced (EIA/TIA-423) transmissions, is a faster version of EIA/TIA-232 (up to 2 Mbps) that provides more functions and supports transmissions over greater distances.

The EIA/TIA-449 standard was intended to replace the EIA/TIA-232 standard, but it was not widely adopted primarily because of the large installed base of DB-25 hardware and because of the larger size 37-pin EIA/TIA-449 connectors, which limited the number of connections possible (fewer than with the smaller, 25-pin EIA/TIA-232 connector).

The network end of the EIA/TIA-449 adapter cable provides a standard 37-pin D-shell connector. (See Figure 2-2.) EIA/TIA-449 cables are available as either DTE (DB-37 plug) or DCE (DB-37 receptacle).

Figure 2-2 EIA/TIA-449 Adapter Cable Connectors, Network End

V.35 Connections

The V.35 interface is recommended for speeds up to 48 kbps, although it is often used successfully at 4 Mbps.

The network end of the V.35 adapter cable provides a standard 34-pin Winchester-type connector. (See Figure 2-3.) V.35 cables are available with a standard V.35 plug or receptacle in either DTE or DCE mode.

Figure 2-3 V.35 Adapter Cable Connectors, Network End

X.21 Connections

The X.21 interface uses a 15-pin connection for balanced circuits and is commonly used in the United Kingdom to connect public data networks. X.21 relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.

The network end of the X.21 adapter cable is a standard DB-15 connector. (See Figure 2-4.) X.21 cables are available as either DTE (DB-15 plug) or DCE (DB-15 receptacle).

EIA-530 Connections

EIA-530, which supports balanced transmission, provides the increased functionality, speed, and distance of EIA/TIA-449 on the smaller DB-25 connector used for EIA/TIA-232, instead of the 37-pin connectors used for EIA/TIA-449. Like EIA/TIA-449, EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423. Although the specification recommends a maximum speed of 2 Mbps, EIA-530 is used successfully at 4 Mbps or faster over short distances.

The EIA/TIA-530 adapter cable is available in DTE mode only. The network end of the EIA-530 adapter cable is a standard DB-25 plug commonly used for EIA/TIA-232 connections. Figure 2-5 shows the DB-25 connector at the network end of the adapter cable.

Mounting the Chassis on the WallCisco 2600 series routers with a chassis height of 1RU can be attached to a wall. Mounting a 2RU chassis to a wall is not recommended and brackets are not provided for mounting to a wall.

Note Use 19-inch brackets (shown in Figure 3-4) to wall-mount the chassis. The small brackets provide the most stable installation for the chassis.

To wall-mount the chassis:

Step 1 Attach the brackets as shown in Figure 3-17.

Figure 3-17 Attaching the Wall-Mount Brackets

Step 2 Attach the chassis assembly to the wall as shown in Figure 3-18, using screws and anchors that you provide. We recommend the following:

• For the best support of the chassis and cables, attach the brackets so that the screws align with a vertical wall stud. (See Figure 3-18.) This position will prevent the chassis from pulling away from the wall when cables are attached.

• For the best ventilation of the chassis, mount the chassis with the power supply and fan at the top. Make sure there is clearance between the router and the wall.

Installing a Network Module or Interface Card
This chapter describes how to install network modules in a Cisco 2600 Series router, and includes information on installing either a WAN interface card or a voice interface card (VWIC) into the appropriate network module. The chapter contains the following sections:

• Installing a Network Module

• Installing a WAN Interface Card

• Installing a Voice Interface Card

Note WAN and voice interface cards can be installed in the network module either before or after the network module is installed in the router chassis.

Installing a Network ModuleThe following instructions apply only to installing a network module in a modular router chassis slot. You can install network modules in the chassis either before or after mounting the router, whichever is more convenient.

Warning Before installing a network module into the router chassis, turn OFF electrical power to the router to avoid the risk of electrical shock to yourself or to the equipment. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Tip Unless the router is using a copy of the Cisco IOS Release 11.3(3)T or later release, you cannot install an ISDN BRI network module (or ISDN BRI WAN interface card) into the same chassis as an ISDN PRI network module.

The following tools are required or recommended for this task:

• ESD-preventive wrist strap

• Number 1 Phillips screwdriver

• Duct or electrical tape (for routers using a DC power supply only)



Step 1 Turn OFF electrical power to the router. Do NOT unplug the power cable. If the router uses a DC power supply, remove power from the DC circuit with the following steps:

a. Locate the circuit breaker on the panel board that services the DC circuit.

b. Switch the circuit breaker to the OFF position.

c. Tape the switch handle of the circuit breaker in the OFF position.

Step 2 Remove all network cables, including telephone cables, from the rear panel of the router.

Caution Network modules are not hot-swappable. To avoid damaging the module, turn OFF electrical power to the chassis and disconnect all network cables, including telephone cables, before inserting or removing a network module.

Step 3 Attach an ESD-preventive wrist strap before handling the card, and connect the wrist strap to an electrical ground.

Step 4 Using a number 1 Phillips screwdriver, remove the blank filler panel from the chassis slot. Save the blank filler panel for future use.

Step 5 Align the network module with the guides in the chassis and slide it gently into the slot.

Step 6 Slide the module into place until the edge connector is securely seated in the connector on the motherboard.

Step 7 Using the number 1 Phillips screwdriver, tighten the module’s captive mounting screws.

Step 8 Reinstall blank panels to fill any unoccupied chassis slots.

Caution To provide proper airflow, install the blank panels shipped with the router in any empty chassis slots.

Step 9 Plug in the network interface cables and turn ON power to the router. For a router using a DC power supply, remove the tape from the circuit breaker and turn the circuit breaker to the ON position.

Installing a WAN Interface Card

Warning Before installing a WAN interface card into the network module, turn OFF electrical power to the router to avoid the risk of electrical shock to yourself or to the equipment. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.






OL-2171-02


Step 1 Turn OFF electrical power to the router and unplug the AC power cord. If the router uses a DC power supply, remove power from the DC circuit with the following steps:





Timesaver Do not install a newer ISDN BRI WAN interface card in the same network module as an older ISDN BRI WAN interface card. To identify the newer cards, look for a horizontal arrangement of channel B LEDs. Older ISDN BRI WAN interface cards have channel B LEDs that are arranged vertically.


Step 4 Using a number 1 Phillips screwdriver, remove the blank filler panel from the base module slot. Save the blank filler panel for future use.

Tip If you are installing a single WAN interface card directly into the chassis, use slot W0 first. The router may not recognize the presence of the WAN interface card in slot W1 if slot W0 is empty.

Step 5 Align the card with the guides in the module slot and gently slide it in.

Step 6 Push the card into place until the edge connector is seated in the connector on the module.

Step 7 Using a number 1 Phillips screwdriver, tighten the captive mounting screws.

Step 8 Reinstall blank panels to fill any unoccupied module slots.

Caution To provide proper airflow, install the blank panels shipped with the router in any empty module or chassis slots.


Installing a Voice Interface Card

Warning Before installing a voice interface card into the voice network module, turn OFF electrical power to the router to avoid the risk of electrical shock to yourself or to the equipment. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

A voice connection requires both a voice network module and a voice interface card. Voice interface cards are not installed directly into the router chassis, but must be installed in a voice network module to function. At least one other network module or WAN interface card must be installed in the router chassis for any desired connections to the IP LAN or WAN to function.


OL-2171-02


Note Voice interface cards must be installed in a voice network module. Voice network module slots are numbered V0 and V1 from right to left on the router chassis.





Step 1 Turn OFF electrical power to the router and unplug the AC power cord. If the router uses a DC power supply, remove power from the DC circuit with the following steps:






Step 4 Using a number 1 Phillips screwdriver, remove the blank filler panel from the voice module slot in the voice network module. Save the blank filler panel for future use.

Caution Do NOT install voice interface cards in a WAN interface card slot or in a two-slot network module.

Step 5 Align the card with the guides in the module slot and gently slide it in.

Step 6 Push the card into place until the edge connector is seated in the connector on the module.

Step 7 Using a number 1 Phillips screwdriver, tighten the captive mounting screws.

Troubleshooting the Router
This appendix contains information about isolating problems with the Cisco 2600 series router and includes the following sections:

• Isolating Problems, page A-1

• Reading the LEDs, page A-2

For information about obtaining technical support, see the “Obtaining Technical Assistance” section on page xiii.

Cisco 2600 series routers include the following models:








• Cisco 2691

Isolating ProblemsThe key to problem solving in this system is to try to isolate the problem to a specific subsystem. By comparing what the system is doing to what it should be doing, the task of isolating and solving the problem is greatly simplified.

When problem solving, consider the following subsystems:

• Power and cooling systems—Power supply, power cable, and fan

• Ports, cables, and connections—Ports on the rear panel of the router and the cables that connect to them

A-1Routers Hardware Installation Guide

Appendix A Troubleshooting the RouterReading the LEDs

Troubleshooting the Power and Cooling SystemsCheck the following items to help isolate the problem:

• When the power switch is in the ON position (|) and the power LED is on, make sure the fan is operating. If not, check the fan.

• If the router shuts down after being on a short time, check the environmental conditions. The router might be overheating, resulting in a thermal-induced shutdown. Verify that the chassis intake and exhaust vents are clear. Review the “General Site Requirements” section on page 23. The operating temperature for the router is 32 to 104°F (0 to 40°C).

• If the router fails to boot, but the power LED is on, check the power supply.

• If the router constantly or intermittently reboots, there might be a problem with either the processor or the software, or a DRAM single in-line memory module (SIMM) might be installed incorrectly.

Troubleshooting the Ports, Cables, and ConnectionsCheck the following items to help isolate the problem:

• If the router fails to recognize a port, check the cable connection.

• When the power switch is in the ON position (|), make sure the power LED is on. If not, check the power source and power cable.

• If the system boots, but the console screen is frozen, verify that the console is configured for 9600 baud, 8 data bits, no parity, and 2 stop bits.

Reading the LEDsThe LEDs indicate the current operating condition of the router. By observing the LEDs, you can note any fault condition that the router is encountering, and then contact your system administrator or customer service, when necessary.

Figure A-1 and Figure A-2 show the locations of the LEDs on the front panel of the Cisco 2600 series routers. Table A-2 and Table A-2 describe these LEDs.

Appendix B Maintaining the RouterUpgrading DRAM

Figure B-3 Removing the Cisco 2691 Router Cover

Upgrading DRAMThis section describes how to upgrade dynamic random-access memory (DRAM) on the system card. You might need to upgrade DRAM for the following reasons:

• You have upgraded to a new Cisco IOS software feature set or release.

• You are using very large routing tables or many protocols (for example, when the router is set up as part of both a large external network and your internal network).

To see how much memory is currently installed in the router, enter the show version command. Near the middle of the resulting output, a message similar to the following appears:

Cisco 2610(MPC860) processor (revision 0x200) with 28672K/4096K bytes of memory.

This line shows how much memory is installed (in this example, 28672K/4096K). The first number represents primary memory and the second number represents shared memory.

OL-2171-02


Memory CapacitiesCisco 2600 series routers use two types of dynamic memory:

• 5V EDO DRAM DIMMs (Cisco 2610, Cisco 2611, Cisco 2612, Cisco 2613, Cisco 2620, and Cisco 2621 routers)

• 3.3V SDRAM DIMMs (Cisco 26xxXM, Cisco 2650, Cisco 2651, and Cisco 2691 routers)

Caution EDO DRAM and SDRAM DIMMs are not interchangeable. Although it is mechanically possible to install an incorrect DRAM DIMM into a router, the router will not boot.

DRAM memory capacities are shown in Table B-1:

Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXMMost Cisco 2600 series routers contain two 100-pin dual in-line memory module (DIMM) sockets (or banks) for DRAM, numbered 0 and 1. (See Figure B-5.) Each socket can be filled with a 100-pin DRAM DIMM (EDO or SDRAM DIMMs depending on router model). You can use the memory-size iomem software command to configure DRAM as a mixture of shared memory, which is used for data transmitted or received by network modules and WAN interface cards, and primary or main memory, which is reserved for the CPU. For further information about this command, refer to the Cisco IOS configuration guides and command references, located at:

Cisco Product Documentation > Cisco IOS Software > Cisco IOS Software Release you are using > Configuration Guides and Command References

Cisco 2691This section describes how to upgrade synchronous dynamic random access memory (SDRAM) dual in-line memory modules (DIMMs) in the Cisco 2691 routers.

The Cisco 2691 router contains two 168-pin DIMM sockets for SDRAM. Each socket can be filled with a single 64-bit-wide, 168-pin SDRAM DIMM. You can configure SDRAM as a mixture of main memory, which is reserved for the CPU, and shared memory, which is used for data transmitted or received by modules and WAN interface cards. See Figure B-7 for DIMM locations.

To see how much memory is currently installed in the router, enter the show version command while the router is in privileged EXEC mode (Router#). Near the middle of the resulting output, a message similar to the following displays:

cisco 2691 (R7000) processor (revision 0.5) with 121856K/9216K bytes of memory.

This line shows how much memory is installed (in this example, 24576K/8192K). The first number represents primary memory and the second number represents shared memory. Your router supports up to 256 MB of SDRAM.

Each DIMM slot corresponds to one bank of memory. Fill banks from 0, and empty banks starting with 1. Bank 0 must always be filled first and emptied last.

The Cisco 2691 router supports both parity and nonparity PC-100 DIMMs ranging in capacity from 64 to 128 MB. Only certain combinations of SDRAM DIMMs are permitted. (See Table B-4.)

Note An advantage of parity DIMMs over nonparity DIMMs is how much easier memory errors are identified; a disadvantage however is lower processing speed.

Note To use a 64-bit mode SDRAM configuration, the DIMM in slot 1 must be less than or equal to the size of the DIMM in slot 0.


OL-2171-02


Figure B-7 SDRAM DIMM Locations in the Cisco 2691 Router

SDRAM DIMM Orientation

DIMMs are manufactured with polarization notches to ensure proper orientation and alignment holes to ensure proper positioning. Figure B-8 shows the polarization notches and alignment holes on a DIMM.

Caution To avoid damaging ESD-sensitive components, observe all ESD precautions. To avoid damaging the system board, do not use excessive force when you remove or replace DIMMs.

Step 4 Beginning with socket 0, insert the DIMM perpendicular to the socket. Push firmly into place, as shown in step 1 of Figure B-9. When the DIMM is properly seated, the socket guide posts fit through the alignment holes, and the locking spring clips click into place, as shown in Step 2 of Figure B-9.

Step 5 Ensure that each DIMM is straight (perpendicular to the socket). (See Figure B-9.)

Caution It is normal to feel some resistance when installing a DIMM, but do not use excessive force on the DIMM, and do not touch the surface components.

Step 6 Repeat Step 3 through Step 5 for each DIMM.

Step 7 Replace the router cover. Follow the instructions in the “Closing the Chassis” section on page B34.

Replacing Flash Memory

Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXMThe system code (router operating system software) is stored in a Flash memory 80-pin single in-line memory module (SIMM).

Tools Required

You will need the following tools to remove and replace the system-code SIMM on the router:

• Medium-size flat-blade screwdriver (1/4-in. [0.625 cm])


• Flash SIMM

Preparing to Install the System-Code SIMM

There is one system-code (Flash memory) SIMM socket on the system board. You can verify how much Flash memory is already installed in your router by entering the show flash EXEC command.

Caution The system code is stored on the Flash memory SIMM, but new system-code SIMMs are shipped without preinstalled software. Before continuing with this procedure, use the copy flash tftp EXEC command to back up the system code to a Trivial File Transfer Protocol (TFTP) server.


OL-2171-02


Note Cisco 2650 and Cisco 2651 routers support a maximum of 32 MB of Flash memory. The Cisco 2620 and Cisco 2621 can be upgraded to supp6rt a maximum of 32 MB of Flash memory when using both the Cisco 2600 boot ROM version 12.2(6r) (supplied with Cisco part number MEM2620-32FSBoot=) and either Cisco IOS Release 12.1(3)T or Cisco IOS Release 12.2T or later Cisco IOS releases. The 32 MB Flash SIMM module is not supported on the Cisco 2610, Cisco 2611, Cisco 2612, or Cisco 2612.

Note For more information about the copy flash tftp command and other related commands, refer to the Cisco IOS configuration and command reference publications. These publications are available on the Documentation CD-ROM that accompanied your router, and on Cisco.com. You can also order printed copies. See “Obtaining Documentation” section on page xii for ordering information.

Caution It is critical that the correct voltage SIMM modules be installed in the Cisco 2600 series routers. Using the incorrect memory will cause the system to malfunction and may cause damage to the system board or memory card. For Flash memory requirements, see Table B-5.

Step 8 Position the new SIMM so that the polarization notch is located at the left end of the SIMM socket.

Caution To prevent damage, note that some Flash memory SIMMs have the components mounted on the rear side; therefore, when inserting the SIMM, always use the polarization notch as a reference and not the position of the components on the SIMM.

Step 9 Insert the new SIMM by sliding the end with the metal fingers into the SIMM connector socket at approximately a 90º angle to the system card. Gently rock the SIMM back into place until the latches on both sides snap into place. Do not use excessive force because the connector might break.

Step 10 Replace the router cover following the procedure in the “Closing the Chassis” section on page B34.

Step 11 Refer to the “Procedures for Recovering Boot and System Images” section on page C6 for instructions on how to place the Cisco IOS image on the new SIMM.

Appendix B Maintaining the RouterInstalling and Formatting Compact Flash Memory Cards in Cisco 2691 Routers

Installing and Formatting Compact Flash Memory Cards in Cisco 2691 Routers

The operation system software, or image, is stored in Flash memory on a compact Flash memory card. This section describes how to install compact Flash memory cards in Cisco 2691 routers, how to format the cards into a Class B Flash file system (low end file system) or a Class C Flash file system (similar to DOS), and how to perform file and directory operations in each file system. In Cisco 2691 routers, the compact Flash memory card mounts on a connector on the system board. You can install a compact Flash memory card with 32-, 64-, or 128-MB of memory.

This section contains the following subsections:

• Preventing Electrostatic Discharge Damage, page B-18

• Tools and Equipment Needed, page B-18

• Compact Flash Memory Card Installation and Removal, page B-19

• Formatting Procedures for Compact Flash Memory Cards, page B-20

• File and Directory Operations, page B-22

Preventing Electrostatic Discharge DamageCompact Flash memory cards can be damaged by electrostatic discharge (ESD). ESD damage, which can occur when electronic cards or components are handled improperly, can cause complete or intermittent failures.

Follow these guidelines to prevent ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• Place a removed compact Flash memory card on an antistatic surface or in a static shielding bag. If the card will be returned to the factory, immediately place it in a static shielding bag.

• Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

• Do not remove the wrist strap until the installation is complete.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Tools and Equipment NeededYou need the following tools and equipment to remove and install compact Flash memory cards:


• Antistatic bag or mat

• Number 2 Phillips screwdriver or flat-blade screwdriver


OL-2171-02


Compact Flash Memory Card Installation and RemovalTo remove or install a compact Flash memory card mounted internally on the router, perform the procedures described in this section.

Removing the Chassis Cover

See the “Removing the Chassis Cover on Cisco 2691” section on page B4 for instructions on removing the Cisco 2691 chassis cover. This section describes how to remove the chassis cover to access the compact Flash memory card.

Removing the Compact Flash Memory Card

After removing the chassis cover, complete the following steps to remove the compact Flash memory card from the router:

Step 1 Locate the compact Flash memory card on the system board. (See Figure B-12.)

Figure B-12 Compact Flash Memory Card Location in a Cisco 2691

Step 2 Remove the retention screw that retains the compact Flash memory card by using the Phillips screwdriver; save the retention screw for reinstallation.

Step 3 Carefully pull the compact Flash memory card free from the connector.

Installing the Compact Flash Memory Card

You can install a compact Flash memory card with 32-, 64-, or 128-MB of memory.

Complete the following steps to install the compact Flash memory card:

Step 1 Locate the compact Flash memory-card connector on the system board. (See Figure B-12.)

Step 2 Insert the connector end of the compact Flash memory card into the connector until the card is seated in the connector. The card is keyed, so that it cannot be inserted incorrectly.

Step 3 Reinstall the retention screw to retain the compact Flash memory card.

Step 4 Install the chassis cover as described in the “Replacing the Chassis Cover on Cisco 2691” section on page B35.

Step 5 Refer to the “Formatting Procedures for Compact Flash Memory Cards” section on page B20 for instructions on formatting the compact Flash memory card.

Formatting Procedures for Compact Flash Memory CardsCisco recommends that you erase (Class B) or format (Class C) new compact Flash memory cards to initialize them with either a Class B or Class C Flash file system. This ensures proper formatting and enables the ROM monitor to recognize and boot the Flash.

The Class B Flash file system is also known as the low end file system (LEFS).

The Class C Flash file system is similar to the standard DOS file system.

Note A compact Flash memory card formatted with the standard DOS file system does not support booting from the ROM monitor.

Determining the File System on a Compact Flash Memory Card

To determine the file system of a compact Flash memory card in a Cisco 2691, enter the show flash: command.

• If geometry and format information of the card is not displayed, the card is formatted with a Class B Flash file system.

• If geometry and format information of the card is displayed, the card is formatted with a Class C Flash file system.

The following examples show outputs for Class B and Class C Flash file systems:

Appendix B Maintaining the RouterReplacing the Boot ROM

Replacing the Boot ROM

Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXM Routers

Note 32 MB Flash memory support is limited to the Cisco 2620(XM), Cisco 2621(XM), Cisco 2650(XM) and Cisco 2651(XM). The Cisco 261x (2610, 2611, 2612 and 2613) cannot be upgraded to support 32 MB of Flash regardless of the boot ROM version.

To upgrade the router ROM software to a new ROM monitor version, you must replace the existing ROM. Follow this procedure to replace the ROM:

Caution Correct placement of the ROM is crucial. If improperly positioned, the new component could be damaged when the router is powered on. Read all instructions before proceeding. To prevent damage to the ROM from ESD (when handling the router and its components), follow the ESD procedures described in your hardware guide and see the Regulatory Compliance and Safety Information document. Be careful not to damage or scratch the printed circuit card under the ROM.

Step 1 Locate the ROM on the system card (motherboard) layout as shown in Figure B-13 and Figure B-14.

Testing ROM Installation

Tip Before testing your ROM installation, close the router chassis using the procedure provided in the “Closing the Chassis” section on page B34.

Test your installation by rebooting the router. If you installed the ROM correctly, the router will boot into the ROM monitor or operating system.

If you suspect that the ROM is inserted incorrectly, remove and reinstall the ROM as described in the “Replacing the Boot ROM” section on page B29. Reboot the router again.

Cisco 2691The boot Flash device on the Cisco 2691 router is a 1 MB, fixed Flash device that is not field-replaceable. The ROM image can be upgraded by downloading new software. The first image in ROM is read-only and cannot be erased and the upgrade image is a read-write image that is stored in ROM Flash as the second image. You can configure the router to boot from either image.

In order to upgrade the ROM on the Cisco 2691, you will need to have a ROM image file available to copy from a remote server or internal Flash memory.

Follow these steps to upgrade the Cisco 2691 ROM from a TFTP server:

Step 1 Copy the ROM image from the TFTP server:

Router# upgrade rom-monitor file tftp://172.19.169.99/rommon_file.srecLoading rommon_file.srec from 172.19.169.99 (via FastEthernet0/0): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!![OK - 651041/1301504 bytes]Router#This command will reload the router.

Closing the ChassisThis section describes the procedure for closing the chassis.

Replacing the Chassis Cover on Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXM

To close the chassis:

Step 1 Position the two chassis sections, as shown in Figure B-2.

Step 2 Referring to Figure B-2, press the two chassis sections together and verify the following:

• The top section fits into the rear of the bottom section. The bottom section fits into the front of the top section.

• Each side of the top and bottom sections fits together.

Caution To fit the two sections together, it might be necessary to work them together at one end and then the other, working back and forth; however, use care to prevent bending the chassis edges.

Step 3 When the two sections fit together snugly, slide the chassis top so it fits into the front bezel.

Step 4 Replace the cover screws. Tighten the screws to no more than 8 or 9 inch/pound of torque.


OL-2171-02

Appendix B Maintaining the RouterClosing the Chassis

Step 5 Reinstall the chassis on the wall, rack, desktop, or table.

Step 6 Reconnect all cables. If the router uses a DC power supply, switch the circuit breaker to the ON position.

Replacing the Chassis Cover on Cisco 2691

Step 1 Place the chassis bottom so the front panel is closest to you.

Step 2 Hold the cover so the tabs at the rear of the cover are aligned with the chassis bottom.

Step 3 Push the cover toward the rear, making sure that the cover tabs fit under the chassis back panel, and the back panel tabs fit under the cover.

Slide the cover slightly to the left to lock the cover into position (See part 1 in Figure B-17).

A P P E N D I X C
Using the ROM Monitor
This appendix describes using the ROM monitor (also called the bootstrap program), which is the firmware that runs when you power on or restart a Cisco 2600 series router. During normal operation, the ROM monitor helps to initialize the processor hardware and boot the operating system software. You can also use the ROM monitor to:

• Help you isolate or rule out hardware problems encountered when installing your router.

• Recover your router’s Cisco IOS image if the image becomes corrupted.

This appendix contains the following sections:

• Entering ROM Monitor Mode, page C-1

• ROM Monitor Commands, page C-2

• ROM Monitor Syntax Conventions, page C-3

• Command Descriptions, page C-3

• Procedures for Recovering Boot and System Images, page C-6

Entering ROM Monitor ModeTo use the ROM monitor, you must have access to the console port. Refer to the Cisco 2600 Series Cabling and Setup quick start guide for information on connecting the console cable.

To enter ROM monitor mode follow these steps:

Step 1 Restart the router with the reload command.

Router # reload

Step 2 Press the Break key during the first 60 seconds of the system booting. This forces the router into ROM monitor mode.

C-1Routers Hardware Installation Guide

Appendix C Using the ROM MonitorROM Monitor Commands

Verifying ROM Monitor ModeTo verify that you are in the ROM monitor mode, check that the prompt displayed on your screen is the ROM monitor mode prompt:

rommon # >

The # is the line number and increases incrementally at each prompt.

From the Cisco IOS software, you can configure the router to automatically enter ROM monitor mode the next time the router boots by setting virtual configuration register bits 3, 2, 1, and 0 to zero. From the console, enter the following configuration command:

configuration-register 0x0

The new configuration register value, 0x0, is effective after the router is rebooted with the reload command. The router remains in the ROM monitor and does not boot the operating system.

As long as the configuration register value remains 0x0, you must manually boot the operating system from the console. Refer to the boot command in the “Command Descriptions” section on page C-3.

ROM Monitor CommandsEnter ? or help at the ROM monitor mode prompt to see a list of available commands. For example:

rommon 1 > ?alias set and display aliases commandboot boot up an external processbreak set/show/clear the breakpointconfreg configuration register utilitycont continue executing a downloaded imagecontext display the context of a loaded imagecookie display contents of cookie PROM in hexdev list the device tabledir list files in the file systemdis display instruction streamdnld serial download a program moduleframe print out a selected stack framehelp monitor builtin command helphistory monitor command historymeminfo main memory informationrepeat repeat a monitor commandreset system resetset display the monitor variablesstack produce a stack tracesync write monitor environment to NVRAMsysret print out info from last system returntftpdnld tftp image downloadunalias unset an aliasunset unset a monitor variablexmodem x/ymodem image downloadrommon 2 >

The Cisco 2691 has these additional ROM monitor commands:

Appendix C Using the ROM MonitorROM Monitor Syntax Conventions

ROM Monitor Syntax ConventionsThe ROM monitor syntax in this appendix uses the following conventions:

• Square brackets [ ] denote an optional element. In the following example, the element abc is not required, but you can specify it if you choose:

command [abc]

• If a minus option is followed by a colon (for example, [-s:]) you must provide an argument for the option.

• A term in italics means that you must fill in the appropriate information. In the following example, you replace the term in italics with the interface type you are using:

command type interface

Command DescriptionsThis section lists some useful ROM monitor commands. Refer to the Cisco IOS configuration guides and command references for more information on ROM monitor commands.

• boot or b—Boot an image.

– b boots the first image in Flash memory.

– b flash:[name] boots the Cisco IOS software from the Flash memory.

– b filename tftpserver boots from the specified file over the network from the specified Trivial File Transfer Protocol (TFTP) server. For example:

boot c2600-i-mz 172.15.19.11

– b filename boots from the boothelper image because it does not recognize the device ID. This form of the command is used to netboot the image named filename.

Cisco 2600 series routers do not have a dedicated boothelper image ([rx]boot) as used by some other Cisco routers. With Cisco 2600 series routers, the first image in Flash memory is invoked as the default boothelper image anytime the ROM monitor does not recognize the device ID in the boot command.

You can override the default boothelper image setting by setting the BOOTLDR monitor environment variable to point to another image. Any system image can be used for this purpose.

Options to the boot command are -x, load image but do not execute, and -v, verbose.

Use the Cisco IOS commands show version and show hardware to see the source of the currently running image.

• dir device:[partition:]—List the files on the named device. For example:

rommon 8 > dir flash: File size Checksum File name 2229799 bytes (0x220627) 0x469e C2600-j-m2.113-4T

• help—View a summary of ROM monitor commands (equivalent to ?).


OL-2171-02

Appendix C Using the ROM MonitorCommand Descriptions

• meminfo—Display size in bytes, starting address, available range of main memory, the starting point and size of packet memory, and size of nonvolatile memory (NVRAM). The following example shows the meminfo command:

rommon 9 > meminfo

Main memory size: 32 MB.Available main memory starts at 0xa000e000, size 32704KBIO (packet) memory size: 25 percent of main memory.NVRAM size: 32KB

• meminfo [-l]—The meminfo command with the -l option shows supported DRAM configurations. The following example shows an example of the meminfo -l command:

rommon 10 > meminfo -l

Supported memory configurations:

DIMM 0 DIMM 1------------------- 4M 8M-DUAL 16M 32M-DUAL4M4M 4M4M 8M-DUAL4M 16M4M 32M-DUAL8M-DUAL8M-DUAL 4M8M-DUAL 8M-DUAL8M-DUAL 16M8M-DUAL 32M-DUAL16M16M 4M16M 8M-DUAL16M 16M16M 32M-DUAL32M-DUAL32M-DUAL 4M32M-DUAL 8M-DUAL32M-DUAL 16M32M-DUAL 32M-DUAL

• reset or i—Reset and initialize the router, similar to power on.

• tftpdnld—Download an image using TFTP from a remote server.

Debugging CommandsMost debugging commands are functional only when Cisco IOS software has crashed or is ended. If you enter a debugging command and Cisco IOS crash information is not available, the following error message appears:

“xxx: kernel context state is invalid, cannot proceed.”

• stack or k—Produce a stack trace.

• context—View processor context.

• frame—View an individual stack frame.


OL-2171-02

Appendix C Using the ROM MonitorCommand Descriptions

• sysret—View return information from the last booted system image. This information includes the reason for terminating the image, a stack dump of up to eight frames, and, if an exception is involved, the address where the exception occurred. For example:

rommon 8 > sysretSystem Return Info:count: 19, reason: a SegV exceptionpc:0x802b1040, error address: 0x802b1040Stack Trace:FP: 0x80908398, PC: 0x802b102cFP: 0x809083b0, PC: 0x802b0b88FP: 0x809083d8, PC: 0x8017039cFP: 0x809083e8, PC: 0x8016f764

Configuration Register CommandsThe virtual configuration register resides in NVRAM. You can view or modify the virtual configuration register from either the ROM monitor or the operating system software.

To change the virtual configuration register from the ROM monitor, enter confreg by itself for menu mode, or enter the new value of the register in hexadecimal.

• confreg [hexnum]—Change the virtual configuration register to the value specified. The value is always interpreted as hexadecimal. Entering confreg without an argument displays the contents of the virtual configuration register and prompts you to alter the contents by describing the meaning of each bit.

In either case, the new virtual configuration register value is written into NVRAM, but is not effective until you reset or power cycle the router.

The following display shows an example of the confreg command:

rommon 7 > confreg

You must reset or power cycle for new config to take effect

Procedures for Recovering Boot and System ImagesIf your Cisco 2600 series router experiences difficulties and no longer contains a valid Cisco IOS software image in Flash memory, you can recover the Cisco IOS image using one of the following ROM monitor commands:

• xmodem—Use this command if the computer attached to your console has a terminal emulator that has Xmodem capability.

• tftpdnld—Use this command if you have a TFTP server directly connected to the Ethernet 0 port or Token Ring 0 port.

Note The tftpdnld command is not available on the Cisco 2691 router. In addition to the xmodem command, the router can be booted with a good image loaded in the external compact Flash slot.

Using the xmodem CommandThe xmodem command establishes a connection between a console and the router console port for disaster recovery if both the boot and system images are erased from Flash memory.

xmodem [filename]—Establishes an Xmodem connection between the console and the router. The optional parameter filename specifies the source file containing the Cisco IOS image.

Other options include the following:

• c—Use cyclic redundancy check (CRC-16)

• y—Use Ymodem transfer protocol

• r—Copy the image to dynamic random-access memory (DRAM) for launch

• x—Do not launch image on completion of download

Using the tftpdnld CommandThe tftpdnld command downloads a Cisco IOS software image from a remote server accessible from an Ethernet or Token Ring network interface on a Cisco 2600 series router. The tftpdnld command downloads the Cisco IOS software image into Flash memory using TFTP.

The following software restrictions apply when using the tftpdnld command:

• Ethernet platform—Only accepts and sends Ethernet V2.0 data packets.


OL-2171-02


• Token Ring platform—Only accepts and sends Token Ring frames with IEEE802.3 SNAP frames. Does not support any frames with routing information fields (RIFs), limiting all use of the tftpdnld command to a TFTP server on the local ring. If the TFTP server resides off the local ring, you must establish a path to the server through a router or transparent bridge from the local ring.

tftpdnld [-h] [-r]—Begins the TFTP copy procedure.

Options include the following:

• h—Displays the tftpdnld command help screen.

• r—Loads the Cisco IOS software image only to DRAM and launches the image without writing the image into Flash memory.

The tftpdnld command requires that you specify certain variables when you issue the command. The syntax for specifying the variables is:

VARIABLE_NAME=value

The variables that you must specify include the following:

• IP_ADDRESS—IP address for the router you are using.

• IP_SUBNET_MASK—Subnet mask for the router you are using.

• DEFAULT_GATEWAY—Default gateway for the router you are using.

• TFTP_SERVER—IP address of the server from which you want to download the image file.

• TFTP_FILE—Name of the file that you want to download.

The following tftpdnld command variables are optional:

• TFTP_VERBOSE—Print setting. The default is 1.

– 0=quiet—After you enter the tftpdnld command, the prompt

Do you wish to continue? y/n:

is the only information that displays until the command completes successfully or fails.

– 1=progress—Displays the state of the required tftpdnld command variables. Also displays progress characters to indicate successful and lost packet transmissions.

– 2=verbose—Displays all progress print setting messages, along with error information. The information provided by this print setting may be useful when debugging interface link and configuration problems that may prevent connecting to the TFTP server.

• TFTP_RETRY_COUNT—Number of times from 1 to 65535 that the ROM monitor will retry ARP and ACK. The default is 7 retries.

• TFTP_TIMEOUT—Overall timeout of the download operation in seconds. The range is from 1 to 65535 seconds. The default is 7200 seconds.

• TFTP_CHECKSUM—Performs a checksum test on the image. 0=checksum off, 1=checksum on. The default is 1.

• FE_SPEED_MODE—Sets the Fast Ethernet speed and duplex mode. 0=10 Mbps half-duplex mode, 1=10 Mbps full-duplex mode, 2=100 Mbps half-duplex mode, 3=100 Mbps full-duplex mode, 4=auto-negotiation. The default is 4.

Note Specify the FE_SPEED_MODE variable only for routers with a Fast Ethernet network interface.


OL-2171-02


• TR_SPEED_MODE—Sets the Token Ring speed and duplex mode. 0=4 Mbps half-duplex mode, 1=4 Mbps full-duplex mode, 2=16 Mbps half-duplex mode, 3=16 Mbps full-duplex mode. The default is 2.

Note Specify the TR_SPEED_MODE variable only for routers with a Token Ring network interface; or for routers with both an Ethernet and a Token Ring port, those routers that are set to use the Token Ring port with the tftpdnld command.

• TR_1E1R_PORT—Sets the port to be used with the tftpdnld command. 0=Use Ethernet port, 1=Use Token Ring port. The default is 0.

Note Specify the TR_1E1R_PORT variable only for those routers with both an Ethernet and a Token Ring port.

After you specify the variables, you must reenter the tftpdnld command. For example:

rommon 1 > IP_ADDRESS=172.15.19.11rommon 2 > IP_SUBNET_MASK=255.255.255.0rommon 3 > DEFAULT_GATEWAY=172.16.19.1rommon 4 > TFTP_SERVER=172.15.20.10rommon 5 > TFTP_FILE=/tftpboot/c2600-i-mzrommon 6 > tftpdnld
