The two controllers are automatically synchronized when you replace a failed
controller. The storage-management software automatically synchronizes the
firmware between the existing controller and the new controller.
Replacing a failed controller
When instructed by the storage-management software, replace a controller CRU
using the following procedure.
Attention: After replacing a controller, always use the storage-management
software to verify the firmware levels.
1. Remove the FAStT700 Storage Server bezel, as shown in Figure 20 on
page 16.
Attention: Removing a controller that is operating normally (not failed) can
result in data loss. Only remove a controller that:
v
Has a fault indicator light that is lit
v
Is marked as “Failed” (offline) through the storage-management software
2. Using Figure 33 as a guide, remove the controller that has failed.
a. Squeeze the two center tabs and pull both controller handles outward.
b. Using both handles, pull out on the controller to remove it.

Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 35.
3. Unpack the new controller. Using the proper handling precautions, remove the
new controller from the packing material.
Check the shipping invoice and the controller to make sure that it has the same
memory size as the controller that you just removed.
4. Using Figure 33 as a guide, install the new controller as follows:
a. Squeeze the two center tabs and pull both controller handles outward.
b. Using the handles, slide the controller into the slot until the back edge of
both handles hooks onto the frame.
c. Close both handles and snap into place.
