7.3.4 Defective Memory Disconnection Function

This server is equipped with the defective memory (RAM module) disconnection function.
This function disconnects the memory (one DIMM) judged to be defective (error) during Power On Self
Test (POST) to start the server. When POST is executed, if the memory capacity is discovered to be
smaller than the capacity of the memory installed, there is a possibility of memory defect.
You can check the slot location whose memory is defective during POST or from the system event log.
If the defective memory is discovered, replace it, and then restart the server.

sequent server startup, and a new memory becomes available.
