To install an AC-input or DC-input power supply, follow these steps:
Warning Voltage is present on the backplane when the system is operating. To
reduce risk of an electric shock, keep hands and fingers out of the power supply
bays and backplane areas.
Step 1 Grasp the power supply handle with one hand. Place your other hand underneath
to support the bottom of the supply, as shown in Figure 3-7.
Step 2 Place the power supply into the power supply bay and push the power supply
into the bay until the power supply faceplate is flush with the cover.
Step 3 Tighten the captive installation screw by turning it clockwise.
For detailed power supply installation, removal, and maintenance information, see the
section “Removing and Installing Power Supplies” in the chapter
“Maintaining the Chassis.”
