    Parameter

    Description

    Code

    eqptBrownout

    Description

    Equipment Brownout: A brownout condition has been detected on a UFM that is installed in a BTI7800 Series chassis powered by a DC power entry module (PEM).

    Caution: Continued operation might cause equipment damage.

    Entities Affected

    UFM modules (see table below)

    Note: For UFM3 and UFM4 modules, this alarm results in an automatic cold reload of the UFM.

    Possible Cause

    The supply voltage to a UFM is lower than the minimum normal voltage threshold for the module, but not lower than the power-off threshold.

    Default Severity

    Major

    Service Affecting

    Yes (true)

    Clearing an EqptBrownout Alarm

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

    1. Retrieve environment information to view voltage data for the UFM and each PEM installed in the chassis:
      show environment voltage
    2. Check for and clear alarms raised against the PEMs, and ensure that they are properly seated and connected to power.
    3. Check for alarms on the UFM.
      • If the alarm has cleared, you have completed this procedure.
      • If the alarm does not clear, contact your next level of support.
