5Disconnect the battery unit from the connector by sliding it towards the back of the controller, then remove it from the controller module.

6Place the replacement battery unit into the controller module tray and push the battery unit into the connector on the RAID controller circuit board.

7Tighten the thumbscrew to secure the battery unit to the controller.

8Reinstall the battery cover.

9Reinstall the RAID controller module (see "Installing a RAID Controller Module" on page 60).

10Reset the battery installation date using MD Storage Manager.

Removing and Installing the Power Supply/Cooling Fan Module

Your enclosure supports two separate modules containing an integrated power supply and two cooling fans per module. While the enclosure can operate temporarily with only one functional power supply, both cooling modules (with two fans each) must be present for proper cooling. Three of the four fans must be operational for the enclosure to avoid overheating.

NOTICE: A single power supply/cooling module can be removed from a powered-on enclosure for a maximum period of 5 minutes. Beyond that time, the enclosure may automatically shut down to prevent damage.

Removing a Power Supply/Cooling Fan Module

NOTICE: Power supply/cooling fan modules are hot-pluggable. Provided one power supply/cooling fan module is functioning normally, you can remove or replace the other while the enclosure is powered on.

NOTE: If you remove a fully functioning power supply/cooling fan module, the fan speed in the remaining module will increase significantly to provide adequate cooling. The fan speed will decrease gradually when a new power supply/cooling fan module is installed.

1Turn off the power supply you intend to remove using the on/off switch.

2Using a Phillips-head screwdriver, loosen the two captive screws securing the power supply/cooling fan module in the bay (see Figure 4-6).
