3. Illuminate the UID (Unit Identification) LED of the enclosure that

contains the controller module to remove.

a. Select Manage > General Config > Enclosure Management.

b. Click Illuminate Locator LED.

4. Locate the enclosure whose UID LED (front right ear) is blue, and

within it, the module whose OK to Remove LED is blue.

5. Disconnect any SAS cables that connect the controller to a drive

enclosure.

6. Turn the thumbscrews (2) until the screws disengage from the

controller.

7. Press both latches downward to disconnect the module from the

midplane.

8. Pull outward on the latches to slide the module out of the

enclosure.

Installing the controller module

NOTE: You can install a controller into an enclosure that is

powered on.

1. Loosen the controller’s thumbscrews; press the latches downward.

2. Slide the controller into the enclosure as far as it will go (1).

3. Press the latches upward to engage the controller (2); turn the

thumbscrews finger-tight.

4. Reconnect the SAS cables.

IMPORTANT: In a dual-controller configuration, if the

firmware versions differ between the two controllers, Partner

Firmware Upgrade brings the older firmware to the later firmware

level.

Verifying component replacement

After replacing the controller, check that the OK LED (back)

illuminates green, indicating that the controller has completed

initializing and is online.

If the enclosure’s UID is on, use SMU to turn it off.

1. Select Manage > General Config > Enclosure Management.

2. Click Turn Off Locator LED.

If the Fault/Service Required LED is amber, the module has not gone

online and likely failed its self-test. Put the module online by

following the steps to shut down a controller or check the event log

for errors.
