Control and port circuit pack status LEDs
Issue 4 May 2002 7-7
Control and port circuit pack status
LEDs
Each circuit pack has three LEDs on the front panel visible at the front of the
carrier. On all circuit packs, except the TN736 Power Unit, the LEDs indicate:
1. Red (alarm)
—
If the circuit pack is communicating with the system, the
system has detected a fault in this circuit pack. An on-board alarm for this
circuit pack is displayed in the Alarm Log.
The circuit pack also lights this LED when either the circuit pack has not yet
initialized communication with the system or when the circuit pack loses
contact with the system and stops functioning (circuit pack is said to be “in
reset”). In these cases, there may not be an alarm in the Alarm Log. To
determine if the red LED is lit because the circuit pack is not in contact with
the system, issue the list configuration board PCSS command, where
PCSS refers to the slot containing this circuit pack. If the system does not
detect the circuit pack, this command returns “Identifier not assigned” or
“no board.”
If the circuit pack has just been inserted, the system may still be initializing
the circuit pack. If, after 5 minutes, the circuit pack still has not initialized
communications with the system, check the MO for any special instructions
(for example, EPN Maintenance circuit pack can stop EXP-INTF circuit
pack from initializing). If the MO does not provide the needed information,
perform the following steps:
■
Check the Error Log for TONE-BD and TDM-BUS errors. Enter test
tdm P where P is the port network containing the relevant slot. Refer
to” Restarting Nonfunctioning Port Circuit Packs” in
Chapter 10,
‘‘Maintenance Object Repair Procedures’’ in the general description
of the “TDM-BUS”. Enter test tone-clock PC, where P is the
network containing the relevant slot, and C is the carrier containing
the relevant slot. Follow appropriate sections for any “TONE-BD”
and “TDM-BUS” errors.
■
Reseat the suspect circuit pack.
!
WARNING:
Reseating some circuit packs may be very destructive (for example,
Control Carrier circuit packs.)
Wait 5 minutes. Then issue list configuration board PCSS. If the
result indicates that the system still has not registered the circuit
pack, go to the next step.
■
Try to insert the circuit pack into a different slot and try to insert a
different circuit pack into the suspect slot (provided the maintenance
documentation for this circuit pack does not warn against either of
these actions).
