    HighBer

    Table 1: Alarm Details

    Parameter

    Description

    Code

    highBer

    Description

    High Bit-Error Rate: The local port has detected a bit-error rate in the received signal that is 10-4 or greater.

    Entities Affected

    • Ethernet interfaces
    • Fibre channel interfaces

    See respective tables below.

    Possible Causes

    • Either the fiber link or the optical connection is degraded.
    • There is excessive attenuation of the signal, causing high a signal-to-noise ratio.

    Default Severity

    Major

    Service Affecting

    No (false)

    Alarm Clearing

    Clearing a HighBer Alarm

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

    1. Retrieve detailed information for the interface to determine whether the value of the Optical Power Rx counter is within the range indicated by the Optical Power Received Minimum Threshold and Optical Power Received Maximum Threshold values.
      show interface name:identifier detail

      Note: For detailed transceiver specifications, see the BTI7800 Series Hardware Overview and Installation Guide.

    2. Inspect the fiber connection, and ensure that the fiber is intact, thoroughly clean, and correctly connected to the port.
    3. Ensure that no unintentional attenuation has been added to the fiber.
    4. 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.
