Removing the Controller Module
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
.
Step 3.
Insert the controller module
. Align the controller module
with the controller module bay at the rear of the
subsystem, making sure that the levers are down.
Gently slide the controller 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, use the ejection levers 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 the
retention screws through the holes underneath the
ejection lever.
Step 6.
Re-attach all the cables
that you previously removed.
These include the cables that connect to the local
network or iSCSI initiators that were previously
attached to the iSCSI ports.
Step 7.
7-1.
Power up
the subsystem if using a single-controller
subsystem.
7-2. With a redundant-controller subsystem, RAID
controllers should spend a short while negotiating and
