Removing a power supply

Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

Power off the power supply and remove the power cord.

Loosen the captive screws on the power supply with a Phillips screwdriver until they are completely disengaged from the chassis.

Grasp the handle of the power supply with one hand and pull the module part way out. Support the module bottom with the other hand, and pull the power supply slowly along the guide rails out of the slot.

Place the removed power supply in an antistatic bag.
