Step 8.
Carefully pull the controller module out of the subsystem chassis
keeping one hand underneath to support the weight of the module.
5.2.3 Replacing the Controller Module
If the controller module itself has failed, it must be replaced. To replace a
failed controller module:
Step 1.
Remove the controller module
from the subsystem (see
Section
5.2.2.
) If the BBU and the DIMM module are undamaged, they can
be removed and reinstalled on the new controller module. For
instructions on removing and installing a BBU and a DIMM
module, please see
Section 5.3 and
Section
5.4
.
Step 2.
Install the DIMM module
and BBU
onto the new controller
module; making sure that the modules are securely in place. (See
Section 5.3
)
Step 3.
Install the controller module.
Make sure the levers at the back of
the controller module are down. Align the controller module with
the controller module bay at the rear of the subsystem. Gently slide
the controller module in.
Step 4.
Secure the connection.
Once the controller reaches the end and
you feel the contact resistance, you can lift up the levers on the
sides. The levers will ensure the back-end connectors are properly
mated. (See
Figure 5-4
)

Step 5.
Secure the controller module to the subsystem
by fastening the
two (2) screws previously removed to the holes underneath the
eject levers. (See
Figure 5-5
)
