Procedure
1.
Locate the battery compartment on the system board in the controller.
Note:
a. The battery compartment is located near the edge of the controller system board next to the
mounting posts for the optional host daughter cards.
b. If a host daughter card is installed on the controller, you must remove the card to gain
access to the battery compartment.
2. Insert the flat blade of a small screwdriver into the slot on the battery-compartment cover.

3. Move the screwdriver as shown in the illustration until the cover is released from the
battery-compartment base.
4. Lift the contact tab; then, slide the battery out of the battery compartment.

5. Repeat Steps 1 through 4 to locate and remove the lithium battery in Controller B; then, continue with
Step 6.
6. Dispose of the batteries as required by local ordinances or regulations.
The battery must be recycled or disposed of properly. Recycling facilities may not be available in your
area. For information on disposal of batteries outside the United States, see http://www.ibm.com/
ibm/environment/products/batteryrecycle.shtml or contact your local waste disposal facility.
In the United States, IBM has established a return process for reuse, recycling, or proper disposal of
used batteries. For information on proper disposal of these batteries, contact IBM at 1-800-426-4333.
Installing an optional host interface adapter
About this task
Attention: If you install a host interface adapter in a controller and the storage system contains two
controllers, you must make sure that an identical host interface adapter is installed in the other controller.
To install a host interface adapter, complete the following steps.
Attention: If new host interface adapters are being installed in both controllers, to prevent data loss,
you must shut down the storage system before you remove the controller from the chassis. For the
correct shutdown sequence, see "Turning off the storage system" in Chapter 4. If you are installing new
host interface adapters, you need to schedule time to power down the storage subsystem. Failure to
upgrade both controllers prior to powering on the system results in the controllers having mismatched
host interface adapters. This causes the mismatched controllers to enter into a controller lock-down.
