Knowledge Article: ID B08238001: Power module %d 48V over current fault.

Description

The current in the specified power module exceeds the current nominal fault threshold of +48V.

Causes

The current for the specified power module is above the +48V source fault threshold.

Implications

A current above the 48V threshold generates this event.

Resolutions

Perform these steps:

  1. Reseat the power module.

    Note: Before reseating or replacing a power module, verify that you have enough power modules in the chassis to power the remaining components in the chassis. Otherwise, components might power off, which can disrupt BladeCenter system operations.

  2. Check the event log for other system devices that might be having a similar problem, which might indicate that the problem was caused by an external short. If no external short is found, replace the power module.
  3. If the problem persists, verify that you have a stable power input source.

    Note: (DC Current) Only trained service personnel, other than IBM service technicians, are authorized to make the connections to and disconnections from the -48 volt DC power source. IBM service technicians are not certified or authorized to install or remove the -48 volt power cable. The customer is responsible for ensuring that only trained service personnel install or remove the -48 volt power cable.
