Replacing a ZS3-4 Battery

Language:

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 (No.1 flat-blade) non-metallic screwdriver or equivalent.

Shut down the controller using one of the power-off methods described in Powering Off the Controller.

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.

Extend the controller from the rack as described in Extending the Storage Controller from the Rack.
Remove the top cover as described in Removing the Top Cover.
Using a small, non-metallic screwdriver, press the latch and remove the battery from the motherboard. The battery is shown here.
Press the replacement battery into the motherboard with the positive side (+) facing upward.
To install the top cover:
1. Place the top cover on the chassis (1) so that it is forward of the rear of the storage controller by about an inch (2.5 cm).
2. Slide the top cover toward the rear of the chassis (2) until it seats.
3. Press down on the cover with both hands until both latches engage.
Push the release tabs on the side of each rail and slowly push the storage controller into the rack, making sure no cables obstruct the path of the controller.
Connect the power cords to the power supplies.
Verify that standby power is on, indicated by the Power/OK status indicator flashing on the front panel about two minutes after the power cords are plugged in.
Use a pen, or other pointed object, to press and release the recessed Power button on the storage controller front panel. The Power/OK status indicator next to the Power button lights and remains lit.
Connect data cables to the PCIe card, routing them through the cable management arm.
When the system has finished booting, log in and set the time using the steps in the task Setting Clock Synchronization (BUI) in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.0.
