General

Ceragon designed FibeAir to be highly reliable and relatively maintenance free. In the event of a system failure, the system will provide detailed indications to assist troubleshooting and fault isolation.

This guide explains the alarm indications of the FibeAir system, and contains procedures for troubleshooting and fault isolation.

Maintenance Policy

To ensure simple and efficient system maintenance, the on-site technician will only replace IDU, ODU, or RFU modules, and not repair them. 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 Ceragon warranty.

Maintenance procedures the technician can perform include visual inspection, cleaning, cable/connector repair, link alignment/adjustment, and retorquing antenna mount bolts.

Visual Inspection

The following table lists the suggested preventive maintenance procedures, which include visual inspection of the equipment and verification of operational parameters.

It is recommended to perform the procedures as often as local environmental conditions require. It is recommended to notify the end customer prior to performing any preventive maintenance procedures that could affect service on the circuit.

Troubleshooting Guide

The Process

Corrective maintenance consists of the steps described in the following sections. The steps provide a logical, sequential method for diagnosing and resolving system problems.

Step 1: Define the Symptom

This step is generally peformed by the customer's field technician or supervisor. Examples of symptoms include “IDU alarm is red”, “complete loss of service”, and “excessive errors”.

Symptoms may be constant or intermittent. Constant symptoms require immediate troubleshooting attention. Intermittent symptoms may require circuit monitoring or robust test procedures prior to troubleshooting.

Step 2: Isolate the Problem

After you have a clear definition of the symptom, the malfunction can be isolated using diagnostics, loopback testing, fault isolation tables/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 suspicion should be focused on one of the following near-end or far-end issues:

y Power supplies

y Fading (due to heavy rain, new obstacle in path, antenna misalignment) y External equipment (SONET/SDH, ATM, Fast Ethernet, etc.)

y Indoor Unit (IDU)

y Outdoor Unit (ODU)or Radio Frequency Unit (RFU) y RF cable between the ODU/RFU and IDU

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

Step 3: Understand the Problem

Once the fault has been isolated, you will need to understand why the fault occurred and what is required to correct it. Use the tables provided in the following sections to understand the problem, and for suggestions of possible solutions.

Alarm List Table

The table below lists trap IDs, trap descriptions, probable causes, and corrective actions.

A note about interface troubleshooting:

If, after the radio link is installed, the payload is not received, there may be a problem either with the line interface connection to FibeAir, or with external equipment.

Before you perform line interface troubleshooting, check the following items, which are common causes of line interface failures:

y External equipment Tx is connected to FibeAir Rx. y External equipment Rx is connected to FibeAir Tx.

y Both external equipment and FibeAir are using the same interface (single mode, multi-mode). y For multi-mode interfaces, check that you are using multi-mode fibers to connect the unit. For single

mode interfaces, check that you are using single mode fibers.

If no problem is detected with any of the items above, proceed with the table below.
