1. If you are not already grounded, properly ground yourself.
2. Identify the power supply you want to replace, based on console error messages or through the red Fault
LED on the power supply.
3. Disconnect the power supply:
a. Open the power cable retainer, and then unplug the power cable from the power supply.
b. Unplug the power cable from the power source.
4. 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.

5. Using both hands, support and align the edges of the power supply with the opening in the controller
module, and then gently push the power supply into the controller module until the locking tab clicks into
place.
The power supplies will only properly engage with the internal connector and lock in place one way.
