Oracle X7-2 - Servicing the Battery (CRU); Remove the Battery

Servicing the Battery (CRU)
This section describes how to service the system battery. The system battery is a customer-
replaceable unit (CRU) that requires you to power off the server. For more information
about CRUs, see “Illustrated Parts Breakdown” on page 19 and “Customer-Replaceable
Units” on page 21.
The real-time clock (RTC) battery maintains system time when the server is powered off and
a time server is unavailable. If the server fails to maintain the proper time when the system is
powered off and not connected to a network, replace the battery.
Caution - Ensure that all power is removed from the server before removing or installing
the battery. You must disconnect the power cables from the system before performing this
procedure.
