Cisco ONS 15454 DWDM Troubleshooting Guide. This guide discusses all DWDM alarms.
2.7.114 FE-DS1-MULTLOS
The Far-End Multiple DS-1 LOS Detected condition occurs when multiple DS-1 signals are lost on a
far-end DS-1 card.
The prefix FE means the main alarm is occurring at the far-end node and not at the node reporting the
FE-DS1-MULTLOS condition. Troubleshoot the FE alarm or condition by troubleshooting the main
alarm at its source. The secondary alarms or conditions clear when the main alarm clears.
Clear the FE-DS1-MULTLOS Condition
To troubleshoot an FE condition, determine which node and card link directly to the card reporting the
Step 1
FE condition. For example, an ONS 15454 FE condition on a card in Slot 12 of Node 1 could relate to a
main alarm from a card in Slot 6 of Node 2.
Step 2 Log into the node that links directly to the card reporting the FE condition.
Clear the main alarm. Refer to the appropriate alarm section in this chapter for troubleshooting
Step 3
instructions.
Step 4 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.
2.7.115 FE-DS1-NSA
The Far End DS-1 Equipment Failure Non-Service-Affecting (NSA) condition occurs when a far-end
DS-1 equipment failure occurs, but does not affect service because the port is protected and traffic is able
to switch to the protect port.
Clear the FE-DS1-NSA Condition
To troubleshoot an FE condition, determine which node and card link directly to the card reporting the
Step 1
FE alarm. For example, an alarm from a card in an ONS 15454 Slot 12 of Node 1 could link to an alarm
from a card in Slot 6 of Node 2.
Log into the node that links directly to the card reporting the FE condition.
Step 2
Clear the main alarm. Refer to the appropriate alarm section in this chapter for troubleshooting
Step 3
instructions.
