System battery
The server uses a nonvolatile memory that requires a battery to retain system information when power
is removed. This 3-volt 200-mAh lithium coin cell battery is located on the system board.
If the server no longer automatically displays the correct date and time, the system battery that
provides power to the real-time clock may need to be replaced. Under normal use, battery life is 5 to
10 years.
