Chapter 11 Installing the AC Shelf
Installing an AC Power Supply
The AC Power Supply must be installed and removed as an integral unit. There may be one or two AC
Power Supplies depending on node configuration. They are housed in the Power Supply Tray.
To install an AC Power Supply in the Power Supply Tray:
Step 1 First install the Power Supply Tray in a rack (see “Installing an AC Power Supply Tray” section).
Step 2 Set the circuit breakers at the rear of the Power Supply Tray to OFF.
Note
When replacing an AC power supply, the circuit breaker at the rear of the Power
Supply Tray may be left ON as the power supplies are hot pluggable.
Step 3 If not already removed, remove the Power Supply Tray front Air Intake Grille. Locate the small access
hole in the top, center of the front Air Intake Grille for the Power Supply Tray (see Figure 11-7).

Step 4
Insert a small slotted blade screwdriver (0.20/0.25 inch blade width) into the access hole until it stops,
approximately 1 inch (2.5 cm).
Step 5
Carefully rotate the screwdriver approximately a quarter turn in either direction. The top of the Air
Intake Grille should spring out.
Step 6 Loosen the captive screw in the center of the power supply retainer and rotate the hinged retainer frame
down (see Figure 11-8).
