Alarm Thresholds

Alarm thresholds set the lower limits of an alarm level. When the severity of an alarm (measured by the percentage of a device type that is faulted or unavailable) exceeds an alarm threshold, a new alarm level is reached.

Default alarm thresholds are shown in the table below.

Default Alarm Thresholds (% faulted or unavailable)

  • Note: The value ">0"  indicates "greater than 0%".

  • Notes:

  • The Two PSU alarm may be cleared on a reboot. After the reboot, you must check the logs or the PSU LEDs to identify which PSU failed.

  • A major alarm is raised if the controller temperature exceeds 55 degrees Celsius. After the temperature in the controller drops below 50 degrees Celsius, the alarm is cleared.  This alarm applies to the MXe controller, MXe Server, CX/CXi/CX II/CXi II controllers, and AX controller only.
