Replacing the Server Battery/Real Time Clock (RTC)
The server's battery runs the server clock and retains any setup information when it is turned off. If the server
ever fails to retain the correct date, time, or configuration settings when it is turned on, you need to replace the
server's battery.
To replace the battery, perform the following:
1) Record server configuration settings using the SCU.
2) Turn off the server.
3) Disconnect external devices, ac power, and monitor power.
4) Unlock and remove left side panel.
5) Remove old battery.
6) Install new battery. Make sure pin 1 of the battery is aligned with pin 1 on the socket (A).
7) Replace and lock left side panel.
8) Connect external devices and restore power.
9) Run SCU to reconfigure computer using recorded configuration settings from step 1.
WARNING
Depending on the locality, the server’s battery might be considered hazardous waste.
Make sure to follow any state or local statute to properly dispose of the old battery.
