Replacing the CMOS battery
If the server clock does not keep time or the settings in the BIOS Setup utility
are not saved when you turn off the server, replace the CMOS battery with an
equivalent battery.
To replace the battery:
1 Print the appendix for BIOS Settings in this guide.
2 Open the BIOS Setup utility by following the instructions in “Opening the
BIOS Setup utility” on page 72.
3 Record the BIOS settings on your printout, then exit from the utility. For
more information, see “Recording your BIOS configuration” on page 35.
4 Turn off your server, then follow the instructions in “Preventing static
electricity discharge” on page 41.
5 Open the server case by following the instructions in “Opening the server
case” on page 42.
6 Locate the old battery on the system board and note its orientation. You
will need to install the new battery the same way.
Warning Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the manufacturer. Dispose of used
batteries following the manufacturer’s instructions.
