7.4.4 Defective Memory Disconnection Function

This Server Blade is equipped with the defective memory (RAM module) disconnection function.
This function disconnects memory blocks (two DIMMs) judged to be defective (abnormal) during
Power On Self Test (POST) to start the Server Blade. 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.
From POST error messages or the system event log, you can check the slot location that has defective
memory.

If defective memory is discovered, replace it, and then restart the Server Blade.
Replacing the defective memory
Replace the defective memory with a new one according to "7.4.3 How to Install/Remove Memory
Module" ( pg.186).
After replacing the memory module, start the BIOS Setup Utility and select the [Server] menu - the
[Memory Status] submenu to check that [DIMM n,n] (n is the number of the replaced memory module)
for the replaced memory module is set to [Enabled]. If the item is set to [Disabled], change the setting
to [Enabled]. If it is not set to [Enabled], the server will start with the memory module recognized as
being defective and constantly disconnected.
To use a new memory module, set the item to [Enabled] for releasing the failed memory status at the
next startup.
