== Step 2: Move the power supplies
You must move the power supplies from the impaired controller module to the replacement controller
module when you replace a controller module.
1. Rotate the cam handle such that it can be used to pull power supply out of the controller module while
pressing the locking tab.
The power supply is short. Always use two hands to support it when removing it from
the controller module so that it does not suddenly swing free from the controller module
and injure you.
