Step 3 Clear the main alarm.
1.3.49 FE-DS1-MULTLOS
• Not Alarmed (NA) (Condition)
Multiple inputs detect a loss on the far end. 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-DS1-MULTOS 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-DS1-MULTLOS Condition on the DS3XM-6
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 Look up and troubleshoot the main alarm.
1.3.50 FE-DS1-SNGLLOS
• Not Alarmed (NA) (Condition)
One of the DS-1 inputs on the far end detects an LOS. The prefix FE in an alarm message means the
main alarm is occurring at the far-end node and not at the node reporting this FE-EQPT-FAILSA 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-DS1-SNGLLOS Condition on the DS3XM-6
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 Look up and troubleshoot the main alarm.
