Follow these steps to install the DC-input power supply.
Insert the DC-input power supply, and then slide it to the front and side of the chassis. Please note that
Step 1
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
Insert the air duct. Squeeze it gently at the bottom so that the four snaps on the duct are captured by the
Step 3
sheet metal retainers in the chassis. See
Step 4 Connect the primary power cable to the power supply. Make sure that the locking feature on the power
supply end snaps into position. See
Step 5 Connect the secondary power cable to the power supply and to the secondary power connector on the
motherboard. Make sure that the locking feature on the power supply end snaps into position. See
