Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide, R3.3
May 2002
Chapter 1 Alarm Troubleshooting
Alarm Procedures
1.5.63 SQUELCH-PATH
• Minor, Non-service affecting
The squelching path alarm applies to the STM-N card. It is raised when there is a misconnection in the
high-order path. A card or node may be powered down, or all fiber may have been removed, even though
the signal is present. Once the circuit gets a squelch, the system sends an AU-AIS.
Warning
The ONS 15454 SDH is a Class I (CDRH) and Class 1M (IEC) laser system.
Warning
Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber optic
modules when no fiber cable is connected. Avoid exposure and do not stare into open apertures.
Procedure: Clear the SQUELCH-PATH Alarm
Step 1 Check for the AU-AIS condition and the SQUELCH-PATH alarm at the adjacent card or node.
Step 2 If the condition is present, complete the “LOS (STM-N)” procedure on page 1-41.
1.5.64 SSM-FAIL (BITS)
• Minor, Non-service affecting
The failed to receive synchronization status message alarm means the synchronization status messaging
(SSM) received by the ONS 15454 SDH failed. The problem is external to ONS 15454 SDH. The
ONS 15454 SDH is set up to receive SSM, but the timing source is not delivering valid SSM messages.
Procedure: Clear the SSM-FAIL Alarm
Step 1 Check that SSM is enabled on the external timing source.
Step 2 Use a test set to determine that the external timing source is delivering SSM.
1.5.65 SWMTXMOD
• Critical, Service-affecting
The switching matrix module failure alarm occurs on the XC10G card or an I/O card. If the alarm reports
against an I/O card, it means that the logic component on the cross-connect card is out of frame (OOF)
with the logic component on the reporting I/O card. All traffic on the reporting I/O card is lost. If the
alarm reports against an XC10G card, it means that a logic component internal to the reporting XC10G
card is out of frame with a second logic component on the same XC10G card. One or more I/O cards
may lose traffic as a result of this failure.
