5.2.4 Replacing the Controller Module
If the controller module has failed, replace a failed controller with a
replacement from your vendor:
Step 1.
Remove the failed controller.
Step 2.
Install a DIMM module on the replacement controller, if it
does not come with a DIMM. See the section Replacing or
Upgrading Memory Modules in this chapter for more
information.
Step 3.
Insert the controller module. Align the controller module with
the controller module bay, making sure that the levers are
down. Gently slide the module in.
Step 4.
Secure the connection. When the controller is reaching the
end and you feel the contact resistance, use slightly more force
to mate the controller with backplane connectors. When the
controller is almost fully inserted, pull the ejection levers up to
secure the controller. The levers help ensure that the back-end
connectors are properly mated.
Step 5.
Fasten the retention screws. Once fully inserted, secure the
controller module to the chassis by fastening retention screws
through the holes on the ejection levers.
Step 6.
Re-attach all the cables that you previously disconnected.
Step 7.
Power up the system.
Check for system message on the LCD screen, GUI manager,
or firmware menu-driven utility. When the replacement
controller is successfully brought online, its Controller status
LED should light green on its faceplate.
