Insert CompactPCI Power Supplies
The radio and utility shelves each contain two or three identical CompactPCI power supplies. See
pages 69 and 71 for the locations of the power supplies.
Utility shelves and completely filled radio shelves use three power supplies each; half-full radio shelves
require only two power supplies. This ensures that the shelves will continue to operate should one of
the power supplies fail.
 To insert CompactPCI power supplies
1 Ensure that there are no obstructions in the slot or on the guide rails.
2 Remove a CompactPCI power supply from its antistatic bag.
3 Set the two ejector handles on the power supply in the open position by turning the handles away from
the center of the front panel while pressing the locking tabs located at the end of each handle.
In the open position, the ejector handles are at an approximately 30°
angle from the front panel.
4 Ensure that the two mounting screws located under and beside each ejector handle are withdrawn
enough to allow for the insertion of the power supply.
5 Orient the power supply so that the text on the front panel is right-side up.
6 Slide the power supply into the left-most unoccupied power slot. Use the guide rails to ensure the
connectors are aligned. Apply sufficient pressure to fully mate the power supply with the shelf.
7 Lock the power supply in the slot by pressing down on the ejector handles until the handles are flush with
the front panel.
You can hear a click when the lock engages.
8 Secure the power supply in the slot using four 2.5-mm mounting screws. Torque each screw to 4
inch-pounds.
9 Repeat steps 1 to 8 for the remaining power supplies.
WARNING: The power supplies use components that are sensitive to electrostatic
discharges (ESD). Make sure you are wearing an approved and regularly tested
grounded wrist strap connected to the grounding point on the PDP. When you handle
the power supplies, hold them by their handles or edges. Do not touch electrical
connections, pins, or soldered surfaces.
