Clearing an EnvTempLowTh Condition

Note

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

Note

Refer to the BTI7800 Series Software Configuration Guide before rebooting a traffic module or to the BTI7800 Series Hardware Overview and Installation Guide before reseating (removing and reinstalling) or replacing equipment or traffic modules.

  1. Retrieve environment information to view the temperature reading for the equipment or traffic module:
    show environment temperature
  2. Ensure that the ambient temperature is within the specified range for chassis operation. For information, see the BTI7800 Series Hardware Overview and Installation Guide.
  3. Check for alarms on the equipment or module.
    • If the alarm has cleared, you have completed this procedure.

    • If the alarm does not clear, go to the next step.

  4. Do the following:
    • If the alarm is raised against equipment, reseat the equipment.

    • If the alarm is raised against a traffic module, perform a warm reboot of the module.
