0x0149FFFF

Major

Yes

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 mainboard is faulty.

Procedure

  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 mainboard. Then, check whether the alarm is cleared

    For details about how to replace the mainboard, 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.
