2.Stop data transfers.
3.Disconnect the VHDCI cable.
4.Squeeze the release lever and the finger hook together while pulling the controller module out of the enclosure.
5.Transfer the cache and batteries from the degraded controller module to the replacement controller module.
6.Insert the replacement controller module into the enclosure until it is firmly seated in the enclosure.
7.Connect the VHDCI cable to the connector on the new controller module.
CAUTION: To prevent damage to the cable connector, do not use excessive force when tightening the thumbscrews on the connector.

Battery Packs and Cache (in the Controller Module)
WARNING: There is a risk of explosion, fire, or personal injury if the battery pack is not properly handled. To reduce this risk:
•Do not try to recharge the batteries if they are disconnected from the controller.
•Do not expose the battery pack to water, or to temperatures higher than 60°C.
•Do not abuse, disassemble, crush, or puncture the battery pack.
•Do not short the external contacts.
•Replace the battery pack only with the designated HP spare.
Battery disposal should comply with local regulations. Alternatively, use established parts return methods to return the battery pack to HP for disposal.
IMPORTANT: When replacing either battery, disconnect both batteries from the controller board as described in these instructions. This ensures that the circuitry on the controller board is reset, and the controller can then recognize the new battery.
1.Flush the cache.
2.Remove the controller module from the enclosure (for detailed instructions, refer to the Controller Module section).
