HARDWARE INSTALLATION
RACKMOUNT INSTALLATION FOR 4-POST RACK
To prevent the risk of fire or electric shock, only use the supplied hardware to attach the mounting
brackets.
Step 1: Rackmount ear & hanging bracket installation
Attach two rack mount ears to the step-down transformer using eight black M5X7L flat head screws.
Install hanging brackets using six silver M5X6L pan head screws
Step 2: Rackmount rail Installation
The rails adjust to mount in 19 in (48 cm) racks from 20.5 in to 36 in (52 cm to 91.5 cm) deep. Select
the proper holes in the rack for positioning the step-down transformer in the rack. The step-down
transformer takes up 2 rack units: rack hole positions 1 through 6.
Position the guide screws on the back of the rackmount rails into the rear rack square holes to
temporarily support the rails in place.
Step 3: Adjust rackmount rails to fit your rack
Adjust the rail depth to match your rack depth. Attach the rackmount rail to your rack with two black
M5X6L pan head screws and two plastic washers at the front of the rack (square holes 1 and 4 as shown
below). Secure the rail to the rear of the rack with two black M5X12L screws and two plastic washers.
