EntityTrapFaultID Indicates the cause ID of the alarm.

Impact on the System

The board overheats. If the temperature is higher than the fatal high temperature threshold, the board will be powered off, leading to service interruption.

Possible Causes

The fan is faulty, causing high temperature of the board.


  1. Run the display temperature all command to check the device temperature.
  2. Run the display fan command to check the fan status and speed. Cool the device quickly. If a fan alarm is displayed at the same time, replace the fan.
