Oracle^® ZFS Storage Appliance Customer Service Manual

Replacing a ZS5-2 System Battery

Removing the battery is a cold-service operation. You must power off the appliance before you remove the battery. There will be a loss of access to the storage unless the system is in a clustered configuration.

You might need to replace the battery if the storage controller fails to maintain the proper time when powered off and disconnected from the network. You will need a small, non-metallic screwdriver (No.1 flat-blade) or equivalent. Use the following procedure to replace a ZS5-2 battery.

1. Power off the storage controller as described in Powering Off the Controller.
2. Disconnect the AC power cords from the rear panel of the storage controller.

   ---

   Caution  -  Because 3.3 VDC standby power is always present in the system, you must unplug the power cords before accessing any cold-serviceable components.
