Replacing the Server Battery/Real Time Clock (RTC)
Your server’s battery runs the server clock and retains any setup
information when it is turned off. If your server ever fails to retain the
correct date, time, or configuration settings when it is turned on, you need
to replace your server’s battery/RTC.
To replace the RTC, perform the following:
1. If you have not already done so, record server configuration
settings using the SCU.
2. Turn off your server.
3. Disconnect external devices, ac power, and monitor power.
4. Unlock and remove left side panel.
5. Remove old RTC.
CAUTION:
Depending on your locality, your server’s
RTC might be considered hazardous waste. Make sure
you follow any state or local statute to properly dispose of
the old RTC.
6. Install new RTC. Make sure pin 1 of the RTC is aligned with pin
one on the socket (A, Figure 3-11).
7. Replace and lock left side panel.
8. Connect external devices and restore power.
