If the memory size is incorrect, re-install or replace the DIMM.
NOTE:
It is normal that the CLI or GUI of the server OS displays a smaller memory size than the actual size
if the mirror, partial mirror, or memory rank sparing memory mode is enabled. In this situation, you
can verify the memory size from HDM or BIOS.
Replacing the system battery
WARNING!
To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before
touching them.
The server comes with a system battery installed on the system board, which supplies power to the
real-time clock and has a lifespan of 5 to 10 years. If the server no longer automatically displays the
correct date and time, you might need to replace the battery.
NOTE:
The BIOS will restore to the default settings after the replacement. You must reconfigure the BIOS to
have the desired settings, including the system date and time.
