1 Reporting of this alarm for a wavelength channel is supported only on multiwavelength CFP transceivers.

Clearing a LaserTempHighTh Alarm

Note

Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.

Note

Refer to the BTI7800 Series Hardware Overview and Installation Guide before replacing a traffic module or a transceiver.

  1. Optionally, retrieve detailed information for the interface to view the Laser Temperature and Laser Temperature Max. Threshold values:
    show interface name:identifier detail
  2. Replace either the pluggable transceiver installed in the port or, if the alarm is raised against an interface provisioned on an integrated MSA, the UFM.
  3. Check for alarms on the interface.
    • If the alarm clears, you have completed this procedure.

    • If the alarm does not clear, contact your next level of support.
