2.7.131 FEPRLF
The Far-End Span Manual Switch Working Facility to Protect condition occurs when a four-fiber BLSR
span is switched from working to protect at the far-end node using the Manual Span command. This
condition is only visible on the network view Conditions tab and is accompanied by WKSWPR. The port
where the Manual Switch occurred is indicated by an “M” on the network view detailed circuit map.
Clear the FE-MANWKSWPR-SPAN Condition
Step 1 To troubleshoot an FE condition, determine which node and card link directly to the card reporting the
FE alarm. For example, an FE-AIS condition from the OC-48 card in Slot 12 of Node 1 could link to the
main AIS condition from an OC-48 card in Slot 6 of Node 2.
Step 2 Log into the node that links directly to the card reporting the FE condition.
Step 3 Complete the “Clear a BLSR External Switching Command” procedure on page 2-269.
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.
2.7.131 FEPRLF
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
The Far End Protection Line Failure alarm occurs when an APS channel “SF-L” condition on page 2-223
occurs on the protect card coming into the node.
Note The FEPRLF alarm occurs when bidirectional protection is used on optical cards in a 1+1 protection
group configuration or four-fiber BLSR configuration.
Clear the FEPRLF Alarm on a Four-Fiber BLSR
Step 1 To troubleshoot the FE alarm, determine which node and card link directly to the card reporting the FE
alarm. For example, an 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.
Step 3 Clear the main alarm. Refer to the appropriate alarm section in this chapter in this chapter for procedures.
Step 4 If the alarm 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.
