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.
Inserting a Controller Module
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.
