Move the controller module hardware - AFF A250
To replace the controller module hardware, you must remove the impaired node, move
FRU components to the replacement controller module, install the replacement controller
module in the chassis, and then boot the system to Maintenance mode.
Step 1: Remove the controller module
You must remove the controller module from the chassis when you replace a component
inside the controller module.
Make sure that you label the cables so that you know where they came from.
Use the following video or the tabulated steps to replace a controller module:
1. If you are not already grounded, properly ground yourself.
2. Unplug the controller module power supplies from the source.
3. Release the power cable retainers, and then unplug the cables from the power supplies.
4. Insert your forefinger into the latching mechanism on either side of the controller module, press the lever
with your thumb, and gently pull the controller a few inches out of the chassis.
If you have difficulty removing the controller module, place your index fingers through the
finger holes from the inside (by crossing your arms)
