Installing 4” X 5” Cards

4”x 5” CARD

The power distribution interface (PDI) is mounted to the back of each expansion cabinet. The PDI contains slots for up to eight 4”x 5” slave cards. Since the PDI carries power and data across the entire bay, it solves most interconnection issues, especially between

4”x 5” cards.

Use the following instructions and the figure below to mount 4”x 5” slave cards to an expansion cabinet.

1.Screw two standoffs and washers to the appropriate holes in the back of the cabinet. These holes must line up with the screw holes in the 4”x 5” card. See Figure 3-24.

2.Plug the 4”x 5” card into the appropriate blind mating connector. Seat the card firmly onto the PDI when installing to ensure complete insertion of the power connector into the PDI.

3.Secure the top of the card to the standoffs with two #6 torx screws and washers.
