Cisco ONS 15454 Troubleshooting and Maintenance Guide
November 2001
Chapter 1 Alarm Troubleshooting
A far-end DS-3 equipment failure is occurring. The prefix FE in an alarm message means the main alarm
is occurring at the far-end node and not at the node reporting the FE alarm. Troubleshoot the FE alarm
by troubleshooting the main alarm at its source. Both alarms clear when the main alarm clears.
Procedure: Clear the FE-EQPT-FAIL-SA Condition on the DS3XM-6 or DS3E Cards in C-bit Format
Step 1 To troubleshoot an FE alarm, determine which node and card link directly to the card reporting the FE
alarm. For example, an FE-AIS alarm from the DS3XM-6 card in Slot 12 of Node 1 may link to the main
AIS alarm from a DS3XM-6 card in Slot 6 of Node 2.
Step 2 Log into the node that links directly to the card reporting the FE alarm.
Step 3 Clear the main alarm.
1.3.52 FE-EQPT-NSA
• Not Alarmed (NA) (Condition)
A non-service affecting equipment failure is detected in the far-end DS-3. The prefix FE in an alarm
message means that the main alarm is occurring at the far-end node, not the node reporting this
FE-EQPT-NSA alarm. Troubleshoot the FE alarm by troubleshooting the main alarm at its source. Both
alarms clear when the main alarm clears.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454.
Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf
assembly.

AIS alarm from a DS3XM-6 card in Slot 6 of Node 2.
Step 2 Log into the node that links directly to the card reporting the FE alarm.
Step 3 Look up and troubleshoot the main alarm.
1.3.53 FE-IDLE
• Not Alarmed (NA) (Condition)
A far-end node detects an idle DS-3 signal. The prefix FE in an alarm message means that the main alarm
is occurring at the far-end node, not the node reporting this FE-IDLE alarm. Troubleshoot the FE alarm
by troubleshooting the main alarm at its source. Both alarms clear when the main alarm clears.
