Cisco NCS 2000 series Troubleshoot Manual

The Laser shutdown due to wavelength drift condition is raised when the transmit wavelength of the
ONS-XC-10G-C XFP drifts beyond the threshold limit. This causes the TX laser to shut down to avoid
transmitting a wavelength that is not provisioned in the network.
Clear the LASER-OFF-WVL-DRIFT Condition
SUMMARY STEPS
1. Provision a different wavelength or replace the affected ONS-XC-10G-C XFP. Refer to the NTP-G326
Install, Provision, and Delete PPMs section in the Installing the GBIC, SFP, SFP+, and XFP Optical
Modules in Cisco ONS Platforms to replace the affected XFP.

If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/c/en/us/support/index.html
for more information or call Cisco TAC (1 800 553-2447).
LASERBIAS-DEG
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
Logical Objects: AOTS, OTS
The Laser Bias Current Degrade alarm occurs on an amplifier card (OPT-BST, OPT-PRE, OPT-AMP-C, or
OPT-AMP-17-C), 40-SMR1-C, and 40-SMR2-C cards when laser aging causes a degrade, but not failure, of
laser transmission.
Clear the LASERBIAS-DEG Alarm
SUMMARY STEPS
1. For the alarmed card, complete the Physically Replace a Card, on page 453 procedure.
DETAILED STEPS
For the alarmed card, complete the Physically Replace a Card, on page 453 procedure.
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do
not stare into the beam directly with optical instruments. Viewing the laser output with certain optical
instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could
pose an eye hazard. Statement 1056
