Follow these steps to install the DC-input power supply.

Step 1

Insert the DC-input power supply, and then slide it to the front and side of the chassis. Please note that
there are two hooks inside the front of the chassis that fit into openings on the side of the power supply.
When you slide the power supply to the front and then the side of the chassis, make sure that these hooks
engage corresponding openings on the side of the power supply.

Step 2

Install the power supply retention screw. See

sheet metal retainers in the chassis. See

supply end snaps into position. See
