Knowledge Article: ID B04018000: Blade voltage fault.

Description

Blade CPU has encountered voltage fault.

Causes

A voltage sensor in the specified blade detected a CPU voltage fault.

Implications

When the voltage sensor detects a fault, it will result in this event being generatated.

Resolutions

Perform these steps:

  1. Check the event log to see if this is happening on multiple blades, suspect the power module, not the blade server.
    1. Identify the power module that is causing the problem (the AC or DC LED is not lit).
        Note: If you cannot easily identify which power module is bad, you should schedule downtime before going further.
    1. Remove the power module in the power domain that powers the failing blade servers, one power module at a time.
    2. Wait 5 minutes.
    3. If the issue persists, swap the other power module in the power domain.

  2. If this is happening for a single blade server:
    1. Reseat the blade server.
    2. Update the firmware for the blade server through the advanced management module Web interface (go to Blade Tasks).
    3. Replace the system board (trained service technician only).
