Servicing the Battery

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.
