Removing and Replacing AC and DC Power Subsystem Components
Install the new DC PDU and tighten the (4) screws to secure it to the chassis.
Replace the rear panel and tighten the (16) captive screws.
The rear panel has a lip that fits over the top of the chassis. Be sure to fit
the bottom of the rear panel above the DC horizontal trough.
Replace the DC horizontal trough and tighten the (6) captive screws.
If you have installed an upgraded PDU to accommodate 2800 W PEM,
do not use the old DC horizontal trough. Be sure to install the
replacement DC horizontal trough which has the correct voltage and
warning labels attached to it.
