Troubleshooting Guide 1
General
Ceragon designed FibeAir to be highly reliable and relatively maintenance free. In the event of a systemfailure, 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 Ceragonwarranty.
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.
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

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, FastEthernet, 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.
Step 4: Solve the Problem
Use the troubleshooting information in this guide to help solve the problem.

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 singlemode 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.

Fault Isolation using Loopbacks
The loopback function provides a means of testing the link at various points. During the procedure, theexternal equipment sends a data pattern and monitors its receipt. If the received pattern is identical to the sent
pattern, the connection between the equipment and the loop is confirmed.
Loopback
FibeAir is capable of performing loopback testing at several points in the link. The test is run from the
CeraView management software, or via the SNMP protocol.
During the loopback test, an alarm indication will appear to remind you to cancel the test when you are done.
The following loopback tests can be performed from the window:

Connection Fault Guide
Problems that occur when trying to connect to the FibeAir system using CeraView, may be due to incorrect
cable configuration. If there is a connection problem in the system, CeraView will start, but an hour glass will
appear when the software is loading to indicate that a problem exists.
The following steps will help you identify and correct such problems.
Check the Cables
Refer to the figure below for the following procedures.
1. For Ethernet connection between FibeAir and a PC network card, use a cross cable.
For Ethernet connection between FibeAir and an Ethernet hub (for example, connecting to a LAN jack in
a wall) use a straight cable.
2. For serial connection between FibeAir and a PC serial port, use a straight cable.
7/28/2019 Trouble Shooting Guide IP 10 1500P Nov
44/44
For serial connection using a dial-up modem, use a cross cable.
Cable Connections
Check Read and Write Communities
Ping FibeAir. If ping succeeds, the problem may be with the CeraView software installation, or the computer
TCP\IP stack. Check the read and write communities in FibeAir and in the management station configuration.
If ping fails, there may be a network connectivity problem.
A typical conflict may occur between the IDU configuration and the related CeraView parameter.
In addition, the Agent Address must be identical to the IDU IP address, and the source address must be
identical to the computers address.
The following figure shows a typical example of IP addresses and network configuration.
