Servicing the Battery
The battery is located inside the chassis. See “Internal Component Locations” on page 14. The
battery maintains system time when the server is powered off and disconnected from AC power.
If the IPMI logs indicate a battery failure, replace the battery.
Caution - Ensure that all power is removed from the server before removing or installing
the battery. You must disconnect the power cords from the server before performing these
procedures.
