7.4.4 Defective Memory Disconnection Function
This server is equipped with the defective memory (RAM module) disconnection function.
This function disconnects the memory block judged to be defective (abnormal) 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.
During POST or from the system event log, you can check the slot location that has defective memory.
For the procedure for checking the system event log, refer to "9.3 System Event Log" (
pg.267).
If defective memory is discovered, replace it, and then restart the server.
■ Replacing the Defective Memory
Replace the defective memory with a new one according to "7.4.3 How to Install/Remove Memory
Modules" (pg.177).
After replacing memory, start the BIOS Setup Utility and select the [Server] menu → "8.2.14 Memory
Status Submenu" (pg.228) to check that [Memory Module nn] (nn is the number of the replaced
memory) is set to [Enabled].
If the item is set to [Failed] or [Disabled], change the setting to [Enabled]. If it is not set to [Enabled],
the server will start with the memory recognized as being defective and constantly disconnected.
To use the new memory, set the item to [Enabled] for releasing the failed memory status at the next
startup.
