3 Installing IDU/ODU Radiolink The installation of non-full outdoor link involves the following steps:

1) Initial equipment set up at the customer’s premises; At first it is recommended to configure each unit of the radiolink by setting up the radiolink in domestic circumstances rather than installing it in the actual locations, - this may ease the configuration of the hop, especially management service channel configuration since all the units are conveniently nearby. In order to properly configure the equipment, the hop should be set up in domestic circumstances by interconnecting ODUs using waveguide-coaxial adapters, and coaxial cable. The use of attenuators is preferable, but in case they are not available, the proper measures should be taken into consideration to avoid damage to the receiver of the ODU, see next chapter for more information. This step includes the following: − Unpack all equipment, − Prepare IDU-ODU cables, − Interconnect IDUs and ODUs with IDU-ODU cables for each hop; − Interconnect ODUs: - turn ODUs of one hop against ceiling (with flanges facing upward), or

use attenuators and waveguide to interconnect ODUs. 2) Connecting ASCII terminal to IDU in order to configure the equipment.

Notes: − You can also connect Telnet console, the default IP address of Eth management port is

192.168.205.10 (mask 255.255.255.0) − Use straight through (modem) serial cable to connect ASCII console to IDU (serial port),

use Ethernet patch cable to connect Telnet terminal (PC) to Ethernet management port; − Some parameters mentioned further can not be configured from IDU front panel, but

only from ASCII or Telnet terminals. 3) Configuration of equipment;

• Radio frequency channel and transmitter power: by default the transmitter power is switched off.

• IP settings: − IP address and netmask of the 10Base-T management port, − SLIP port addresses − Routes to all subsequent IDUs in the radiolink

• SNMP settings: − Specify SNMP trap manager IP address − Specify SNMP read and write community names − Specify SNMP NMS hosts

• Multiplexer slot speeds. • Traffic port settings of installed modules.

Complete steps 2 and 3 for each IDU. 4) IDU mechanical installation (rack mounting, module installation), this is discussed in chapter

3.8. 5) ODU and Antenna mechanical installation: this is discussed in chapter 5. Follow further chapters to perform the installation by the plan described above.

3.1 Preparing Radiolink Hop

3.1.1 Required Equipment

In order to simulate one radiolink hop, the following equipment is required: − IDUs (2 pcs.) − ODUs (2 pcs.) − Waveguide-coaxial adapter (2 pcs.) − Attenuator(s), total recommendable attenuation is 80 dB.

Important note: In case if not using attenuators, the transmitter power must be set to -10 dBm to avoid damage to the receiver, - the maximum permissible receiver input level is 0 dBm.

− Coaxial cable to connect both ODUs of the hop. The following cables are recommended: • RG-213, • LMR-400.

− Power supply unit 20-60 VDC of any polarity with: − 24 W or higher output power for each site of 1+0 hop.

3.1.2 Connecting IDU to ODU

Interconnect IDU with ODU at each site performing the following steps: − Connect the cable type-N connector to the type-N connector on the IDU and rotate the collar of the

coaxial connector clockwise to tighten. − Similarly connect the cable type-N connector to the type-N connector on the ODU. − Check to make sure the connectors are still secured.

3.1.3 Interconnecting ODUs

Connect both ODUs as shown in the picture below.

Figure 4. FODU label

3.2 Configuring ODU Parameters The primary parameters for the link to operate properly are frequency channel and transmitter power.

3.2.1 Setting Transmitter Power

The transmitter power of the new equipment is switched off. For both sites of a hop, proceed as follows: − From IDU LCD, using arrow buttons, select Outdoor unit -> Power -> press ENTER − Select required transmitter power using up/down arrow buttons and press ENTER − Select “Yes” and press ENTER to confirm. Normally the IDU LCD displays basic configuration, radio data and alarm status, remaining in the status display mode. To make changes in configuration from IDU LCD, the LCD must be switched from status display mode to setup mode. This can be done by pressing ENTER key. To return to status display mode, press CLEAR key; the LCD will automatically resume to status display mode after a few seconds.

3.2.2 Setting ODU Frequency Channel

For both sites of a hop, proceed as follows: − From IDU LCD, select Outdoor unit -> Chan ## -> press ENTER − Select required frequency channel using up/down arrow buttons and press ENTER − Select “Yes” and press ENTER to confirm.

3.3 Connecting PC to RS-232 Management Port

3.3.1 Connecting Directly to RS-232 Port

In order to interconnect the IDU and the PC directly through serial ports, a straight through modem cable is needed. The serial port of the PC should be configured as follows:

Bits per second - 19200 Data bits - 8 Parity - None Stop bits - 1 Data flow control - None.

In order to connect the PC to the RS232 management port using Hyper Terminal program, which is included in any Windows version, the following steps must be performed. Similar steps can be performed using other terminal emulators. 1. Connect PC to the RS232 serial port with “straight-through” (modem) serial cable. 2. Run “Hyper Terminal” program. 3. Make a New connection, enter connection name.

- 19200 baud rate

3. Save the modem configuration (typically with AT&W string).

Please refer to the documentation accompanied with the dial-up modem for information about configuration of modem.

3.4 Configuring IP Settings The following IP settings must be properly configured at each site in order to connect Web, Telnet or SNMP terminals as well as to be able to access far-end IDU(s) via radio channel. 1. IP address of 10Base-T port, it can be configured from an ASCII console, or from IDU front panel

using keypad; Using IDU keypad: − using arrow buttons, select Ethernet -> Select IP -> press ENTER − select required IP address using up/down arrow buttons and press ENTER − select “Yes” and press ENTER to confirm. Using ASCII console, enter command: IP addr <IPaddress> Example: IP addr 192.168.200.1

2. Set the IP netmask for 10Base-T port;

Using IDU keypad: − select Ethernet -> Select NETMASK -> press ENTER − select netmask using up/down arrow buttons and press ENTER − select “Yes” and press ENTER to confirm. Using ASCII console, enter command: IP mask <IPnetmask> Example: IP mask 255.255.255.0

3. Default gateway; Using IDU keypad: − select Ethernet -> Select Gateway -> press ENTER − select required IP address using up/down arrow buttons and press ENTER − select “Yes” and press ENTER to confirm. Using ASCII console, enter command: IP gw <IPaddress> Example: IP gw 192.168.210.1

4. Set the SLIP address for the serial port of the local IDU: Using IDU keypad: − select Service line -> Select local IP -> press ENTER − select required IP address using up/down arrow buttons and press ENTER − select “Yes” and press ENTER to confirm. Using ASCII console, enter command: IP seraddr <IPaddress> Example: IP seraddr 192.168.100.1

5. Specify the far-end SLIP port IP address:

Using IDU keypad: − select Service line -> Select remote IP -> press ENTER

− select required IP address using up/down arrow buttons and press ENTER − select “Yes” and press ENTER to confirm. Using ASCII console, enter command: IP remaddr <IPaddress> Example: IP remaddr 192.168.100.2

The management traffic in CFM radiolinks is IP-based. The management controller of the IDU operates as a router (2-port), which implies that standard IP routing principles must be taken into consideration.

3.5 Connecting PC to 10Base-T Management Port

3.5.1 Connecting Telnet Client

− Connect a PC to the 10Base-T port of the IDU; if connecting PC directly to the IDU, use crossover patch cable.

− Open telnet client program. − Open Telnet session to the address of IDU 10Base-T port; − Enter login and password if prompted; default (factory) Telnet username is “telnet”, password “saf”

(login name and password is case sensitive). Note: it may be necessary to configure IP address of the PC.

3.5.2 Connecting Web Terminal

− Connect a PC to the IDU 10Base-T management port, using Cat 5 UTP or better patch cable, Note: if connecting a PC directly to the IDU, then crossover patch cable must be used.

− Open Web browser. − In address bar enter the IP address of 10Base-T management port.

This should open the login/password dialog box, default (factory) login name is “SAF” and password “test” (login name and password is case sensitive) If server can not be found then:

− if PC is connected directly to the IDU (not via Ethernet network) then make sure the PC and IDU are in one subnet;

− if PC is connected to the IDU via Ethernet network then make sure the routing of packets addressed to IDU, are properly configured through the network.

Note: it may be necessary to configure IP address of the PC.

3.6 Configuring Management Service Channel The configuration of the management service channel should be done preferably before the IDU is installed at the actual location, in future to avoid necessities to attend each site locally. To configure the service channel, please proceed in the order of the following chapters.

3.6.1 Adding routes

− Connect a PC to the 10Base-T port of the IDU and open Telnet session as described in chapter Connecting Telnet Client, or connect a PC to the RS232 port and make a connection.

− Configure routing using the following command: Route add <destinationIPaddr> Mask <netmask> <gateway> [metric] where <destinationIPaddr> - destination IP address <netmask> - net mask (if the route is related to a single host, the mask can be skipped) <gateway> - gateway [metric] - optional Examples: Route add 192.168.205.010 Mask 255.255.255.0 155.13.79.13 Route add 192.168.205.010 155.13.79.14

− Save the configuration using write command and restart the management controller using restartcpu command. After the restartcpu command is entered, the Telnet session will terminate.

Please refer to chapter IP Configuration Examples for detailed examples.

3.6.2 Pinging Far-end IDU

In order to test if the management service channel is properly configured over the radiolink, use ping command to ping via all hops. Ping in step by step each port along the IP channel between management station (PC) and far-end IDU, starting from 10Base-T port of the local IDU down to the 10-Base-T port of the far-end IDU, correct routes as necessary.

3.7 System Reboot The whole terminal (IDU and ODU) can be rebooted in one way only – by switching the power supply off and on. This will restart all individual modules in IDU and ODU, and will reset all counters, such as up-time and down-time counter. If the restartcpu command is entered from the Telnet or ASCII terminal, or if ‘Restart CPU’ option is performed from IDU panel, the IDU management controller is restarted, but this will not reboot the entire site. Thereby rebooting the management controller does not affect the payload traffic.

− Unpack all equipment, − Prepare necessary cables, − Interconnect FODU with Interface Termination Unit (CFM-8-TU4E1) or other appropriate

interface terminating device; − Interconnect FODUs: - turn FODUs of one hop against ceiling (with flanges facing upward),

or use attenuators and waveguide to interconnect FODUs. 2) Connecting ASCII terminal to serial management port in order to configure the equipment.

Notes: − You can also connect Telnet console, the default IP address of Eth management port is

192.168.205.10 (mask 255.255.255.0). − Use straight through (modem) serial cable to connect ASCII console to interface

termination device, use Ethernet patch cable to connect Telnet terminal (PC) to Ethernet management port;

3) Configuration of equipment: perform basic configuration for each FODU; • Radio frequency channel and transmitter power: by default the transmitter power is

switched off. • IP settings:

− IP address and netmask of the 10Base-T management port, − SLIP port addresses − Routes to all subsequent IDUs in the radiolink

• SNMP settings: − Specify SNMP trap manager IP address − Specify SNMP read and write community names − Specify SNMP NMS hosts.

Complete steps 2 and 3 for each FODU. 4) FODU and Antenna mechanical installation; this is discussed in chapter 5.

5 Outdoor Unit and Antenna Installation 5.1 Polarization Considerations

The position of the ODU determines the polarization of the radio signal. The waveguide flange can be used as the indicator, see picture below.

Figure 10. Position of ODU waveguide flange for vertical polarization and for horizontal polarization

When attaching ODU to the antenna, the antenna waveguide transition polarization must match with the ODU polarization.

5.2 Attaching Outdoor Unit to Antenna

Use M10 nut and washer, whichis screwed on each of two ODUbolts

For further information how to attach ODU to antenna, please refer to the documentation found in ODU delivery package.

5.3 Grounding the Outdoor Unit Attach the site ground to the ODU using the grounding screw provided on the ODU housing, the location of the grounding screw is depicted in the picture below.

5.4 Antenna Alignment

5.4.1 Calculating Expected Receive Signal Level (RSL)

The expected RSL (receive signal level) can be calculated using “path calculator” provided by SAF Tehnika.

5.4.2 Alignment Procedure

The antenna alignment procedure can be made easier by placing one person at each antenna location during alignment process. However, alignment should be performed on one antenna at a time, each person alternatively turns antenna until the RSL is optimized. The following steps are required to properly align the antennas: 1. Start at one end of the link, connect a voltmeter to the RSSI port on the ODU. Ensure the voltmeter

is set to DC voltage and set on a range 0 – 2 volts. 2. Loosen the antenna hardware that is used for securing the antenna movement in the azimuth

directions. 3. Roughly aim the antenna directing the main lobe to the far-end antenna. 4. Slowly sweep the antenna while observing the readings on the voltmeter. The higher is the voltage,

the higher is the RSL. 5. Secure the azimuth adjustment hardware once main lobe is found and the highest signal level is

achieved. 6. Loosen the antenna hardware that is used for securing the antenna movement in the elevation

direction. Slowly sweep the antenna while observing the voltmeter. Once the signal is peaked, the elevation adjustment hardware can be secured.

7. Perform steps 1 through 6 on the opposite end of the link until the signal level is peaked for both azimuth and elevation.

After the AGC voltages have been peaked on both ends of the link, observe the RSL indicated on IDU LCD. Ensure that the RSL is within +/- 5dB of calculated RSL.

5.4.3 RSSI Readings

To aid in the antenna alignment process, the following chart and table shows typical relationship of the RSL (Rx level) vs. RSSI port output voltage (RSSI – Received Signal Strength Indicator). The evaluated Rx level has the error +/-2 dBm.

Important note:

The RSSI port is typically labelled with RSSI . The ODUs which does not have such label, does not correspond to the table and graph given above, the maximum level of RSSI voltage (at peak RSL) for these ODUs may vary from 1.2 up to 2 volts.

Chapter 6. Performing Software Update

21

6 Performing Software Update The software update is performed by loading the newer version of management software in the EPROM. The management software file (with extension .hex, or .txt) can be obtained by contacting local SAF Tehnika reseller. The software is uploaded from the ASCII terminal to IDU management controller, which stores it in the Flash memory (Flash EPROM). Prior to upload the new management software, the current content of management software in the Flash memory must be erased. The update is performed through the following steps: 1. Connect a PC to the RS232 management port, 2. Run the MS Hyper Terminal program, and configure the corresponding COM port as follows:

− 115200 baud, − 8 data bits, − no parity, − 1 stop bit, − no flow control.

3. Configure terminal emulation parameters to values shown in the following picture

4. Unplug power supply or use the reset button (on the rear side) to restart the IDU and press “A” key several times (over 10 times) until the message appears as shown in the picture below. While pressing the “A” key (holding the key down won’t work) the EPROM monitor program stored in the Flash EPROM is executed and the port speed auto-detection is carried out.

When message appears press Enter (on the keyboard) two times.

5. Enter the command “xa” to erase the current contents of management software from Flash EPROM. Note that this command will not erase the EPROM monitor program (which currently runs to perform the upload) but only the section of management software. Note: While the new software will not be loaded, the management system will not work!

22

6. On the Transfer menu, click Send Text File…, choose and open the file (it may have “txt” or “hex” extension).

After about 10 minutes the following notification “Device programmed successfully” should appear (see the following picture), otherwise an error message will be returned.

23

7. Restart the IDU. Notes

For the software upload to Flash EPROM the 115200 bit/s speed should be selected, although in case of certain problems the upload can also be done at 19200 or less bit rate but will take more time to accomplish.

In case if encounter error during the upload, repeat steps 4 - 7.
