What Are Possible Causes of Power Module Alarms on the CloudEngine Series Switches?

What Are Possible Causes of Power Module Alarms on the CloudEngine Series Switches?

A power module reports alarms in the following conditions:

  1. The power module fails to provide normal output due to environmental factors. For example, the power module is not connected to any external power source, the environment temperature is too high, or the input voltage is too high or too low. Alarms generated in this condition are sent to the network management system. When such an alarm is reported, you can fix the environmental problem to enable the power module to work normally.
  2. The power module has a fault that cannot be automatically rectified. For example, fans in the power module fail, internal components of the power module overheat, or a fuse is burnt. When such an alarm is reported, send the power module to Huawei or Huawei agent for repair.
  3. Software of the power module does not work normally. For example, software load has not completed. When such an alarm is reported, upgrade software of the power module.

Power Module Indicators of CloudEngine 12800 and 12800E Series Switches

Table 22-10 lists the indicators on 2700 W AC and 3000 W AC&high-voltage DC power modules and describes the meaning of each indicator state.

Indicator

Color

Description

Input

Green

  • Steady on: The input power of the power module is in the normal range.
  • Blinking: The input voltage is out of the normal range.
  • Off: The power module receives no input power.

Output

Green

  • Steady on: The output power of the power module is in the normal range.
  • Off: The power module provides no output power.

Alarm

Red

  • Off: The power module is working normally.
  • Steady on: The power module has failed. Possible causes include internal short circuit, fan failure, output overvoltage, overtemperature-triggered shutdown, communication failure, and severely uneven current.
