The following system firmware level(s) are affected:

• IMM v1.24 (yuoo91e)

Solution

This behavior is corrected in IMM version 1.25, yuoo91k.

The file is available by selecting the appropriate Product name, Product machine type, and Operating system on IBM Support's Fix Central web page, at the following URL:

Additional information

This is a technical issue between the IMM detect mechanism and the power supplier. The IMM could not recognize the different source of power supply Vital Product Data (VPD) and treat as an unsupported configuration where the VPD data is incorrect. There will be one byte shift with a different source of the power supply VPD, so the PS LPD and CNFG LEDs turn on, requesting to be corrected.

The new IMM code adds the new source mechanism.
