cluster1:*>
system node autosupport invoke -node * -type all -message MAINT=2h

Step 2: 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.
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).
