Knowledge Article: ID B06018000: I/O board voltage fault

Description

A fault has occurred in the I/O expansion blade.

Causes

The addin card sensor has detected a fault in the I/O expansion blade.

Implications

When the addin card sensor detects a fault in the I/O expansion blade, the sensor will issue a message to the advanced management module which will result in this event being generatated.

Resolutions

Perform these steps:

  1. If voltage problem are occurring on multiple blade servers, look for other events in the event log related to power and resolve those events.

    Note: If voltage problems are occurring on multiple blade servers in the same power domain, the problem might be in one of the power modules that power that domain (log in to the advanced management module to see the power modules that are associated with each power domain). Therefore, replace the power modules, one at a time, to see if the problem is resolved.
  2. Reseat the I/O-expansion blade.

  3. Replace the following components one at a time, in the order shown, restarting the blade server each time:

    4.   a. I/O-expansion blade

      b. (Trained service technician only) system board assembly

Refer to the Problem Determination and Service Guide for the specified blade server type for information about removing and installing components. The Problem Determination and Service Guide is available on the Web.
