9.3 Power Supply Installation
The power supply is mounted on the rear of all IDU chassis in the right receptacle as seen from the rear
(refer to Figure 9-4). If redundant power supplies are used the secondary unit is mounted in the left recepta-
cle as seen from the rear.
STEP 1. Position the power supply on the rear of the IDU such that the retaining screws pro-
trude through the four (4) mounting openings of the power supply box.
STEP 2. Slide the power supply down so the multi-pin connector on the bottom of the power
supply mates with the opposite connector on all IDU chassis.
STEP 3. Secure the four (4) retaining screws to all IDU chassis.

9.4 Board Removal
STEP 1. To remove a printed circuit board, grab the two tabs on the edge of the printed circuit
board (refer to Figure 9-3). Extending these tabs will separate the printed circuit board
high-density connector from its mate within the chassis. Slide the printed circuit board
out of the chassis to complete the removal.
