Chapter 14 Alarm Troubleshooting - Cisco ONS 15327 User Documentation

Alarm Troubleshooting
This chapter gives an alphabetical list of Cisco Transport Controller (CTC) alarm messages for the Cisco
ONS 15327. It also lists the cards that host the alarms, and procedures to correct the alarms. The
procedure to correct an alarm applies to the CTC and TL1 version of that alarm.
This chapter also includes a list of threshold-crossing events (EVTs). Login to
http://www.cisco.com/TAC for more information or call the Cisco Technical Assistance Center for
unresolved problems (1-800-553-2447).
Note Some minor differences exist between TL1 error messages and CTC error messages for the ONS 15327.
These discrepancies are resolved in an upcoming release of the ONS 15327. This chapter derives its text
from the error messages as they appear in CTC. For a description of CTC, see Chapter 3, "Using Cisco
Transport Controller."
At the CTC card view, ONS 15327 XTC alarms appear only on the active XTC card. The card- level view
Note
