lit The receiver does not detect a signal (loss of signal/red alarm).





FIGURE 5. IntelliNAC chassis rear view

The Main Processing Unit (MPU), Power Supply modules, and Expansion Card slots are located at the back of the chassis.

All expansion cards are “hot plug” modules. The “hot plug” driver detects expansion card removal with a detect signal and signals the System Manager which in turn notifies the driver control that an expansion card has been removed. This functionality reduces the impact of improper expansion card removal.

This architecture supports both “hot-add” and “hot-removal” of expansion cards and provides a toolbox of mechanisms that allow different user/operator models to be supported.

Hot Plug Features/Functions

IntelliNAC expansion cards are field-replaceable and support hot-plug logic. This allows an expansion card to be removed while power is applied to the system and other card slots are actively sending transactions. This provides the ability to service an expansion card without affecting the other card slot activity.The hot plug expansion cards utilize the following features/functions and must follow the procedure listed below:

• Indicators - show the power and attention state of the slot canister

• Manually-operated Retention Latch (MRL) - holds the expansion card adapter in place

• Attention button - Allows the user to request hot plug operations via insertion and extraction requests

• Slot numbering - Provides visual identification of slots


Expansion Cards

• Power controller - Software-controlled electronic component or components that control power to a slot or adapter and monitor that power for fault conditions.

Slot Indicators

There are three indicators per slot, the Power Indicator, the Attention Indicator, and the expansion card slot indications located on the front of the unit. Each indicator has three possible states: on operational (green), on (amber) indicating non-operational and off (not lit).

Attention Indicator

The Attention indicator (yellow or amber LED) indicates that an operational problem exists and locates a specific slot for the operator.

Indicator Appearance Meaning Description

Off Normal When the Attention indicator is off, neither the module (if one is present) nor the slot require attention

On (amber LED) Attention - Operational problem

When the Attention indicator is on, an operational problem exists with the module or slot. An operational problem is a condition that prevents continued operation of a module. The operating system or other system software determines whether a specific condition prevents continued operation of a module or whether lighting the Attention indicator is appropriate.

In general, this indicates that an operation was attempted and failed or that an unexpected event occurred. The Attention indicator is not used to report problems detected while validating the request for a hot-plug operation.

If the user has removed the power from a module, the user should also remove the module canister from the IntelliNAC.

If the user inserts the module, but does not press the Attention button to turn on the module power, the indicator will light within 30 seconds. When the user presses and holds the button until it lights then releases the button, the indicator will be turned off.

Power Indicator

The Power indicator (green LED) indicates the power state of the slot canister.

Indicator Appearance Meaning Description

Off Power off - insertion or removal of the adapter is permitted

When the Power indicator in the Off state, the insertion or removal of an expansion card is allowed.

On (green LED) Power on - insertion or removal of the adapter is not permitted

When the Power indicator is in the On state, the hot-plug operation is complete, main power to the slot canister is On, and insertion or removal of an expansion card is not allowed.



Removing an Expansion Card

IntelliNAC expansion cards are field-replaceable and support hot-plug logic.

FIGURE 6. Expansion slots

To remove an expansion card:

1. Press and hold the slot’s ATTN button (located near the base of the slot) until the LED flashes, then release. After 3-5 seconds, the PWR indicator LED changes from green to off. You can remove the card. Note: If you leave the card installed, the ATTN amber LED will light solid (approximately 30 seconds) to indicate the card is non-operational and needs attention. You can also remove the card when the ATTN amber LED is on.

2. When the PWR LED is off, loosen the slot thumbscrew.

3. Pull the retention latch. The card unseats from the back plane.

4. Slide the adapter out of the slot.


Expansion Cards

FIGURE 7. Slot retention latch open

FIGURE 8. Slot adapter removed

5. Place the card on a flat surface.

To re-insert the expansion card:

1. Seat the adapter in the appropriate slot.

2. Push the adapter forward to seat the card in the back plane.

3. Close the retention latch.

4. Tighten the thumbscrew.

5. Press and hold the ATTN button until LED flashes, then release to activate. Within 10 seconds, the green PWR LED (Active) turns on indicating the card is powered up.

Note: Please wait for approximately 2 minutes after LED turns green to allow enough time for card driver loads for the new inserted card.



Redundant Power Supply

The IntelliNAC is powered from a redundant modular power system. This means that a single power supply module may be replaced while the chassis is still operational. The power supply is capable of supplying from 750 to 850 watts of redundant power.

Note: The system voltages are not enabled until the system power button is pressed or the remote system instructs the system to do so via the Ethernet System Management interface.

AC Input Voltage

The power supply modules support a universal AC input of 90 - 264VAC @ 47Hz to 63Hz. The module inputs are active power factor corrected.

FIGURE 9. AC Power supplies


Redundant Power Supply

DC Input Voltage

The 48V DC input power supply is available as an option. DC range is 43-56 VDC. The interface provides screw terminals with markings of -48V and 0V and should use spade lugs.

FIGURE 10. DC power supply

Operational Indicator

A visual indicator for the power supply is located on the power supply module. A green LED indicates that the power supply is powered.

Note: The indicator does not show if it is supplying stand-by power.

Stand-by Power

The power subsystem provides stand-by power. When one power supply is unplugged, a high pitch audible alarm will be heard until both power supplies are plugged in. The voltage is provided for the stand-by power as soon as input power is applied to the system.

The power subsystem provides power at full load to the system for three seconds after input has been removed and the input power fail notification has been sent.

Cable Connectors

The IntelliNAC uses a standard IEC connection that accepts an IEC ended cord. The power entry connector and cord have a connection retention force of four pounds.



Replacing the Power Supply Module

The power supply modules are field replaceable without removing the chassis from the rack or disassembling the chassis.

To remove the power supply module:

1. Press and hold down the latching tab.

2. Use the module handle and pull the module out slowly. An audible high pitch sound will be heard, and the front panel Attention button LED will turn amber color. The amber LED indicates Attention is required for one of the power supplies.

Power supply LED

FIGURE 11. Rear view of the unit (close-up)

To replace the power supply module:

1. Reinsert the module into the chamber.

2. Slide in slowly until there is an audible click. Check that this is done.

System Thermal Management

The IntelliNAC chassis contains four fan assemblies to meet environmental requirements. The fans are field replaceable, however it is strongly recommended that only one be replaced at a time. One single fan failure will not cause system shutdown. The system will continue to manage the thermal environment until such time as any monitored device approaches within 5% of its thermal dissipation limit. Once that limit is reached, the Thermal Management will notify the System Manager of the impending system shutdown.


System Thermal Management

FIGURE 12. IntelliNAC fans

Fan failure is defined as:

• If the PWM is at 100% duty cycle (full on) and the tachometer (fan rotational pulse) is off by more than 25% (three-quarter speed).

• The same percent (25%) degradation at any duty cycle

Note: Most fans manufacturers consider a 20% drop in speed as the end of useful life.

Replacing a Fan

To remove a fan:

1. Locate the desired fan.

2. Loosen and unscrew retention screws.

3. Grab the retention screws and slowly slide the fan out. The remaining fans will increase rpms and you will notice an increase in fan speeds. The fan LED indicators located on the front of the unit will change to an amber color for the removed fan.

FIGURE 13. Fan Connector



To replace a fan:

1. Seat the new fan in the fan bay.

2. Slowly slide the fan in the bay.

3. Make certain the fan power connector is located toward the bottom of the unit when inserted.

4. Insert the retention screws and tighten.

Note: Check the fan LEDs, located on the front of the unit, to verify they are working properly.

System Air Flow

The fan speed is adjustable depending on the system temperature. This minimizes the average noise level and increases the MTBF for the fans. The speed is controlled by multiple sensors located on the processing element and the expansion card slot chamber. The speed is determined by the highest sensor reading and location.

Intake Air Filters

FIGURE 14. IntelliNAC air filters

The IntelliNAC fans utilize an air filter for all incoming air used for cooling. The filter is a single piece of poly foam and is retained in the bezel. There is one filter located on the right side panel of the main system, when standing at the front of the unit. The top cover uses thumb screws located at the rear of the unit and need to be removed to get access to this side air filter.

The filter(s) are easy to replace without tools. They should be replaced twice a year in an non-environmentally controlled installation and can be reused after cleaning.

Filter specifications:


Alarms and Alerts

• Filter down to 10 microns

• Flow resistance of lean .01 inch of water.

Alarms and Alerts

Alarm Type Indicator Description

System fan The system monitors fan speed (duty cycle).

Clogged air will also cause a fan failure due to the restricted air flow slowing the fan’s rotation.

Each of the four fans has an indicator on the front of the IntelliNAC that indicates that the fan is functionally normally. If a fan stops working, the indicator turns off and the IntelliNAC reports an alarm to IntelliView.

Also, the fan speed will increase to compensate for the defective fan.

Voltage monitor The Power Good signal is active if the power supplies are within +/- 5% of the specified thresholds

The AC input failure signal is active if the AC main is less than 90VAC.

System voltage error An audible sound and alarm message are reported to the system management and a visual indicator on the front panel is lit.

If the voltage or current is out of tolerance.

The system stores the fault (log the error/fault) and sends a message to the System Manager (IntelliView) indicating the failure. System Manager will then issue a graceful shutdown request to the operating system.



Visual Indicators

The bezel located on the front of the IntelliNAC contains the visual indicators for the system status. The indicators are labeled with international symbols.

Symbol Description Comments

Hardware Peripherals


Expansion card issues

Card slot LED on front panel is amber color. Find appropriate card slot that needs attention (located in the back of the IntelliNAC unit

The expansion cards need attention, some action is required:

The card has been placed in the out of service mode. Or, someone initiated a hot card removal and did not remove the card, the Hot plug feature after 30 seconds will turn on the amber attention LED and place the card out of service

• Within IntelliView, configure the hardware I/O module card and port slots to correct issue.

• To re-insert Hot Card feature, press and the Attention button (until LED flashes, then release) within 10 seconds the card will be placed back in service and the LED will change to green.


Troubleshooting

Card slot LEDS on front panel are off, not lit

No expansion cards are plugged into IntelliNAC

If IntelliNAC has been configured for IP-based routing only, this is normal LED status.

Power Supply Issues

Front panel Power Status LED is amber color and a high pitch audible sound is heard

• Check Power Supply Status LED should be green (on)

• System voltage error on power supply

• If one of the power supplies goes bad, the Power Status LED (on the front panel) turns amber color.

If status LED is off, check AC line cord is plugged in. If okay, replace the power supply. Power supply is defective and you should contact IntelliNAC support group and get a replacement.

Warning: Do NOT open the power supply. This is not serviceable in the field. You will void your warranty.

Unit dead, Power Status LEDs on front panel are off and both power supply status LEDs are off

• Check the AC cord could be loose on the back of the power supplies

• Check both of the AC power breakers/outlets for the IntelliNAC

• Check to see if the MPU canister is properly installed

• Correct loss of AC power to IntelliNAC power supplies

• Confirm AC breakers/outlets are on

• Remove and re-install the MPU

IntelliNAC

MPU status LED blinking red or solid red color

There is an internal issues with the MPU canister

The MPU canister is defective and you should consult the IntelliNAC support group and get a replacement MPU.

Warning: Do NOT open the canister. This is not serviceable in the field and you will void your warranty.



Hardware Peripherals

System cooling issues

Fan LEDs on front panel are amber color and fan speed is loud. Find the fan that needs attention by the amber LED number (see Figures 10 and 11 for fan location)

If one of the four fans is defective or has worked loose during shipment. The LED number indicates whch fan has the operational issue.

• Remove, inspect, and re-install with connector towards the bottom of the unit

• Check for clogged air flow, this will also cause a fan failure due to the restricted air flow slowing the fan’s rotation

• Check the ambient temperature of the room where the unit is installed to see if it meets the humidity/ temperature requirements. If exceeded, the temperature sensors within the system will increase all the fan speed to compensate for the room temperature.

• If all the fans’ speed does not decrease and the amber LED for that fan does not turn green. Then, the fan is defective and you should contact the IntelliNAC support group and get a replacement fan.

• Make sure there is enough clearance around the unit.

• Correct the IntelliNAC’s installation to meet the humidity/temperature requirements.
