Insert CompactPCI Power Supplies
The radio and utility shelves each contain two or three identical CompactPCI
power supplies. See pages 82 and 84 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handle are withdrawn enough to allow for the insertion of the power supply.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 chassis.
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.
