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.

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.

N+1 Link Group protectiondegraded due to Local-Remote ProtectionMismatch.
1) Check that remote IDU isproperly configured with N+1 LinkGroup topology, and all protectionmembers are configured with thesame priority level (if extra traffic isconfigured as revertive in onesubrack, it should also beconfigured the same in the other
subrack).2) Check that remote IDU has allN+1 Link Group protectionpertained line modules operational.3) Verify that remote subrack is notconfigured to lockout or forcedswitch mode.4) Check that the extension cableis connected properly in the remotesubrack (if extended mode isused).

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.

Troubleshooting Guide 38
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 computerTCP\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.
Typical Network Configuration

Check the Serial Connection
If the connection is via serial line, check the serial line speed in FibeAir, and in the Management station
configuration. In the terminal, the serial line speed is specified using the IP Configuration menu.
Check the Ethernet Connection
Verify that the Management station and FibeAir IP interfaces have the same net ID. If they should not be
included in the same network, check the default router address.
After performing the verifications above, if there is still a problem with network connectivity, together with
the system administrator check for firewalls and routing configuration errors.
