3.4.5.2 Determining When to Replace Detected Devices

Note – This section assumes faults are detected by POST in maximum mode.

If a detected device is part of a hardware upgrade or repair, or if POST detects

multiple DIMMs (

CODE EXAMPLE 3-2), replace the detected devices.

Note – The previous example shows two DIMMs on the same channel/rank, which

could be an uncorrectable error.

If the detected device is not a part of a hardware upgrade or repair, use the following

list to examine and repair the fault:

1. If a detected device is not a DIMM, or if more than a single DIMM is detected,

replace the detected devices.

2. If a detected device is a single DIMM and the same DIMM is also detected by

PSH, replace the DIMM (

CODE EXAMPLE 3-3).

Note – The detected DIMM in the previous example must also be replaced because

it exceeds the PSH page retire threshold.
