Defective Memory Disconnection Function - Fujitsu PRIMERGY RX300 S2 User Manual

7.4.4 Defective Memory Disconnection Function

This server is equipped with the defective memory disconnection function.
This function disconnects memory blocks (two DIMMs) 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.
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.185).
After replacing the memory, start the BIOS Setup Utility and select the [Server] menu -"8.2.14 Memory
Status Submenu" ( pg.245) to check that [Module nA/B] (nA/B is the number of the memory slot) is
set to [Enabled].
If the item is set to [Disabled] or [Failed], 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.
