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.
