Fault FindingThe equipment designed to be highly reliable and relatively maintenance free. In the event of a system failure, the system willprovide detailed indications to assist troubleshooting and fault isolation. This chapter explains the alarm indications, and containsprocedures for troubleshooting and fault isolation.

To ensure simple and efficient system maintenance, the on-site technician will only replace IDU or RFU modules, and not repairthem. Under no circumstance will the technician be permitted to open the equipment in order to repair a module or circuit board.Opening equipment will terminate the warranty.

Maintenance procedures the technician can perform include visual inspection, cleaning, cable/connector repair, linkalignment/adjustment, and re-torquing antenna mount bolts.

The following table lists the suggested preventive maintenance procedures, which include visual inspection of the equipment andverification of operational parameters.It is recommended to perform the procedures as often as local environmental conditions require. It is recommended to notify theend customer prior to performing any preventive maintenance procedures that could affect service on the circuit.

Corrective maintenance consists of the steps described below. The steps provide a logical, sequential method for diagnosing andresolving system problems.

Step 1: Define the SymptomThis step is generally performed by the customer's field technician or supervisor. Examples of symptoms include “IDU alarm isred”, “complete loss of service”, and “excessive errors”.Symptoms may be constant or intermittent. Constant symptoms require immediate troubleshooting attention. Intermittentsymptoms may require circuit monitoring or robust test procedures prior to troubleshooting.

Step 2: Isolate the ProblemAfter you have a clear definition of the symptom, the malfunction can be isolated using diagnostics, loopback testing, fault isolationtables/flow charts, test equipment, and manual procedures.This step will identify the specific piece of equipment that is failing.Although it may be difficult at times to immediately determine which part of a radio link is causing the fault, the initial suspicionshould be focused on one of the following near-end or far-end issues:

Power supplies

Fading (due to heavy rain, new obstacle in path, antenna misalignment)

External equipment (SDH/SONET, ATM, Fast Ethernet, etc.)

Indoor Unit (IDU)

Radio Frequency Unit (RFU)

RF cable between the RFU and IDU

Exposure of equipment to severe conditions (high temperature, etc.)

System configuration

Step 3: Understand the ProblemOnce the fault has been isolated, you will need to understand why the fault occurred and what is required to correct it. Use thetables provided in the following sections to understand the problem, and for suggestions of possible solutions.

Step 4: Solve the ProblemUse the troubleshooting information in this chapter to help solve the problem.

What to check Check for… Comments

IDU alarm LEDs All green If not, perform troubleshooting

Coax cable connection Tight, no corrosion or moisture Clean/repair as required

Coax cable No cracks or kinks Replace as required

All equipment Dust or dirt Clean as required

Installing and Replacing Cards in the ChassisThe new card must have exactly the same unit code (Code:) as the unit to be replaced.

Note! This equipment contains components which are sensitive to "ESD" (Electro Static Discharge). It is thereforeessential that whenever disassembling the equipment and/or handling PC boards, special precautions to avoid ESD aremade. These precautions include personnel grounding, grounding of work bench, grounding of tools and instruments aswell as transport and storage in special antistatic bags and boxes.

Replacing the Chassis

Note! When a complete IDU is replaced, the traffic through this IDU will be interrupted.

1. Unplug the power connector(s) on the PDC card(s).2. Disconnect all cables from the cards in the chassis. Mark all cables to ensure that the cables can be reconnected to

the correct cards and interfaces in the new chassis.3. Disconnect the chassis grounding cable.4. Since the chassis fully populated is heavy, It may be convenient to remove cards prior to removing chassis from the

rack.5. Unscrew the chassis from the rack (four screws).6. Carefully pull the chassis out.7. Remove all cards from the chassis.

Replacement1. Replace the cards in the new chassis.2. Carefully insert the new chassis into the rack.3. Fasten the four screws.4. Reconnect the chassis grounding cable.5. Re-insert all cards.Tighten the capive screws gently with a screwdriver.6. Reconnect the front cables.7. Reconnect the power cable(s).

RMC/LIC Installation and Replacement

1. Disconnect all cables on the card to be replaced.2. Unscrew the two captive screws that secure the card to the chassis. A screwdriver may be used if necessary to

unscrew the screws.3. Release the card from the backplane connectors by means of the card ejectors. See animation above.4. Carefully remove the card from the chassis by pulling the screws.

Replacement1. Carefully insert the new card. Ensure that the card enters the guides inside the chassis and gently press the card to

enter the internal connectors without the use of excessive force. Make sure that the card ejectors lock in the correctposition. See animation above.

2. Fasten the two captive screws gently with a screwdriver.3. Reconnect all cables.

TCC Installation and Replacement

Installation of a TCC in a New System

When installing a new system, the new TCC is delivered with an SD card, which stores the unit's software version andconfiguration. The SD card is packaged in a compartment in the front portion of the TCC package. It is placed in such away that you can view the label and serial number of the SD card before opening the package.

1. Carefully remove the SD card from the package.

2. Before installing the TCC, insert the SD card into its socket on the upper left side of the TCC. Make sure theorientation of the SD card is correct, as shown in the figure below.

When the SD card is inserted properly, it should click into place. The figure below shows an SD card properly inserted inits socket on the TCC.

3. Carefully insert the new TCC. Ensure that the TCC enters the guides inside the chassis and gently press the TCC toenter the internal connectors without the use of excessive force. Make sure that the card ejectors lock in the correctposition. See animation below.

4. Fasten the two captive screws gently with a screwdriver.

Replacement

In addition to the procedure below, it is important that the correct system configuration is reloaded from a backup file whenthe TCC is replaced by a new TCC.

1. Remove the SD card. Afterwards, you will insert the SD card into the new TCC in order to preserve the system'scurrent software and configuration. To remove the SD card, press down gently on the card and slide the card out ofits socket on the upper left side of the TCC.

2. Disconnect all cables on the TCC to be replaced.3. Unscrew the two captive screws that secure the TCC to the chassis. A screwdriver may be used if necessary to

unscrew the screws.4. Release the TCC from the backplane connectors by means of the card ejectors. See animation above.5. Carefully remove the TCC from the chassis by pulling the screws.6. Carefully insert the new TCC. Ensure that the TCC enters the guides inside the chassis and gently press the TCC to

enter the internal connectors without the use of excessive force. Make sure that the card ejectors lock in the correctposition. See animation above.

7. Fasten the two captive screws gently with a screwdriver.8. Remove the SFP caps from the TCC.
