Alarm Troubleshooting
FAN-TRAY-REMOVAL
Default Severity: Major (MJ), Service-Affecting (SA)
Logical Objects: FT
The FAN-TRAY-REMOVAL alarm is raised on the NCS 1002 when any of the three fans is removed from
the chassis.
Clear the FAN-TRAY-REMOVAL Alarm
Insert the fan to clear the alarm.
If the alarm does not get cleared, you need to report a Service-Affecting (SA) problem. Log into the Technical Support

HI-LASERBIAS Alarm
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
Logical Objects: PPM
The Equipment High Transmit Laser Bias (HI-LASERBIAS) current alarm is raised against the NCS 1002
laser performance. This alarm occurs when the physical pluggable port laser detects a laser bias value beyond
the configured high threshold. The alarm indicates that the port laser has reached the maximum laser bias
tolerance. You can configure the threshold value using the controller optics R/S/I/P lbc-high-threshold
command in the config mode.
Laser bias typically starts at about 30 percent of the manufacturer maximum laser bias specification and
increases as the laser ages. If the HI-LASERBIAS alarm threshold is set at 100 percent of the maximum, the
laser usability has ended. If the threshold is set at 90 percent of the maximum, the card is still usable for several
weeks or months before it needs to be replaced.
Clear the HI-LASERBIAS Alarm
Step 1
Verify the value of the laser bias high threshold of NCS 1002 using the show controller optics R/S/I/P command.
Step 2
If the value is not within the high laser bias threshold range, configure the high laser bias threshold using the controller
optics R/S/I/P lbc-high-threshold command in the config mode. The range is from 0 to 100%.
Step 3
If the value is within the range of the high laser bias threshold, physically replace the pluggable module. Replacement is
not urgent and can be scheduled during a maintenance window.
If the condition does not clear, log into the Technical Support Website at
for more information or call Cisco TAC (1 800 553-2447).
