Required Tools
You will need a flathead or Phillips screwdriver to perform these procedures.
Removing a Power Supply
Follow these steps to remove a power supply:
Step 1 Set the power switch to the off (O) position.
Step 2 Disconnect the power cord or cords from the power supply being removed. Step 3 Loosen the captive screws.
Caution Use both hands to remove a power supply.
Step 4 Grasp the power supply handles and pull the power supply out an inch to unseat the backplane connections. Place one hand underneath to support the bottom of the power supply.
Step 5 Pull the power supply out of the bay and set it aside.
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
Step 6 If the power supply bay is to remain empty, install a blank power supply filler plate over the opening. Secure the filler plate with the two mounting screws and tighten them with a screwdriver.
