Install the PSU cage

Follow instructions in this section to install the PSU cage. The procedure must be executed by a trained technician.

Procedure

1. Install the power distribution board.
   1. Align the power distribution board with the ten standoffs on the PSU cage; then, lower the power distribution board into the PSU cage.
   2. Fasten the ten screws (PH1, 10 x M3, 0.9 newton-meters, 8 inch-pounds) to secure the power distribution board.

2. Install the two cable retainers to the power distribution board.
   1. Align the cable retainer with the screw holes on the power distribution board; then, place the cable retainer onto the power distribution board.
   2. Fasten the two screws (PH1, 2 x M3, 0.5 newton-meters, 4.3 inch-pounds) to secure the cable retainer.
   3. Repeat to install the other cable retainer.

3. Install the PSU interposer.
   1. Align the PSU interposer with its connectors on the power distribution board; then, press the PSU interposer into the connectors until it is fully seated.
   2. Pull out the two plungers.
   3. Rotate the two release latches down until they stop.

4. Align the power complex with the six guide pins on the chassis; then, lower the power complex into the chassis until it is securely engaged.
5. Locate the ten screw holes marked with P on both sides of the chassis; then, fasten the ten M3 screws (P1-P5) (PH2, 10 x M3, 0.5 newton-meters, 4.3 inch-pounds) to secure the power complex.
