2.7.184 LASEREOL
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
The Laser Approaching End of Life alarm applies to TXP_MR_10G, TXP_MR_2.5G, TXPP_MR_2.5G,
TXP_MR_10E, and MXP_2.5G_10G cards. It is typically accompanied by the “HI-LASERBIAS” alarm
on page 2-122. It is an indicator that the laser in the card must be replaced. How soon the replacement
must happen depends upon the HI-LASERBIAS alarm’s threshold. If the threshold is set under 100
percent, the laser replacement can usually be done during a maintenance window. But if the
HI-LASERBIAS threshold is set at 100 percent and is accompanied by data errors, LASEREOL
indicates the card must be replaced sooner.
Note For more information about MXP or TXP cards, refer to the Cisco ONS 15454 DWDM Reference
Manual.
