Replacing an Oracle ZFS Storage ZS11-2 System Battery

Replacing a system battery is a cold-swap procedure, and you must remove power from the controller. You might need to replace the battery if the controller fails to maintain the proper time when powered off and disconnected from the network. Use the following procedure to replace an Oracle ZFS Storage ZS11-2 system battery.

1. Shut down the controller using one of the power-off methods described in Powering Off the Controller.
2. Disconnect the AC power cords from the rear panel of the 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.
3. Extend the controller from the rack as described in Extending the Controller from the Rack.
4. Remove the top cover as described in Removing the Controller Top Cover.
5. To dislodge the battery from its retainer, place your finger under the side of the battery and gently lift upward.
   
   

   

   
   
6. Lift the battery up and out of its retainer.
7. Unpack the replacement battery.
8. Press the new battery into the battery retainer with the positive (+) side facing up.
9. Replace the top cover on the chassis.
10. Return the controller to the normal rack position by pushing the release tabs on the side of each rail while slowly pushing the controller into the rack.
11. Connect the power cords to the power supplies.
12. Verify that standby power is on.

    Approximately two minutes after plugging in the power cords, the Power/OK status indicator on the front panel begins to flash. This indicator continues to flash for several minutes during the startup sequence. When the Power/OK status indicator remains lit, the system is operational.

13. After the Power/OK status indicator is lit steadily, log in and set the time using the steps in the BUI Clock task. See Setting Clock Synchronization (BUI) in Oracle ZFS Storage Appliance Administration Guide, Release OS8.8.x.
