Alarm message:

Above upper major threshold

This alarm is generated when the voltage of the expander upper than the major alarm upper threshold.

This alarm is generated by the following sensors:

  • EX +1.0V
  • EX +1.2V
  • EX +3.3V
  • EX +5.0V
  • EX +12V

Alarm Severity

Auto Clear




Impact on the System

When devices work with a upper voltage, the component performance deteriorates, the device service life shortens, which causes system breakdown.

Possible Causes

The expander is faulty


  1. Power off the compute node and remove it from the chassis.

    You can power off the compute node using either of the following methods:
    • On the HMM CLI, run the smmset -l bladeN -d powerstate -v poweroff command.
    • On the HMM WebUI, choose PSUs & Fans > PSU Management > Power Control, and click the power control button to power off the compute node.

  2. Replace the expander. Then check whether the alarm is cleared.

    For details about how to replace the expander, see the server user guide.

    • If yes, no further action is required.
    • If no, go to 3.

  3. On the HMM WebUI, choose System Management > Information Collection, and collect logs.
  4. Contact Huawei technical support.
