Replacing the CMOS battery
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 Follow the instructions in “Opening the BIOS Setup utility” on page 154.
3 Record the BIOS settings on your printout, then close the utility.
4 Turn off your server, then follow the instructions in “Preventing static electricity
discharge” on page 65.
5 Follow the instructions in “Opening the server case” on page 66.
6 Remove the memory board or memory board air baffle from slot A by following the
instructions in “Installing and removing memory boards” on page 85.
7 Locate the old battery on the system board and note its orientation. You will need
to install the new battery the same way.
8 Place your finger on the edge of the battery, between the two smaller prongs that hold
the battery in place.
Warning
There is a danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type of battery
recommended by the manufacturer. Dispose of used batteries
following the manufacturer’s instructions.
