Server Alarms - Avaya Support

Circuit Pack LEDs
After a circuit pack has been initialized, a red LED should be accompanied by an alarm in the
alarm log. A single fault can sometimes light alarm LEDs on several circuit packs, as in the
following examples.
● A TDM bus problem may cause several port circuit packs to display red LEDs.
● A Maintenance circuit pack can prevent an Expansion Interface (EI) circuit pack from
initializing.
● Extensive interactions in the Center Stage Switch (CSS) can cause multiple alarms from
single faults in DS1C, SNI and SNC circuit packs and fiber links.
● Tone-Clock or ipserver-interface problems may cause other circuit packs to report alarms.
● Optical fiber cables which are not connected correctly may cause several circuit packs to
alarm.
● Packet bus faults can cause several port circuit packs to display red LEDs.
If a circuit pack has had at least five minutes to be initialized and the red LED is lit without an
associated alarm in the alarm log, the circuit pack may not be in communication with the
system. This may also be the case when a circuit pack is properly administered and present in
its slot, but there is an Error Type 1 logged against it. To determine whether this is so, proceed
as follows:
1. Enter the list configuration board location command. If the system does not
detect the circuit pack, this command will return one of the following:
identifier not assigned
no board
If the documentation for the associated maintenance object gives no special instructions for
this situation, go to the next step.
2. Check the hardware error log for TONE-BD or TDM-BUS errors with the display errors
command. If the board has a “P” suffix, execute the reset board location command.
Otherwise, execute the test tdm, test tone-clock, test ipserver-interface
command. Use the appropriate maintenance procedures to resolve any identified faults. If
this does not resolve the problem, go to the next step.
3. Reseat the suspect circuit pack.
CAUTION: This
! CAUTION:
procedure can cause a partial or total service outage. Consult the
documentation for the associated maintenance object before proceeding.
Observe any precautions and procedures described above.
4. Inspect the backplane connectors for bent pins.
5. If the system seems to be functioning correctly, but the circuit pack in question will not
communicate with the system, replace the circuit pack.
