kit that comes with the chassis.
• Always place the heavier equipment in the lower half of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting the chassis.

•
There is at least 3 inches (7.72 cm) of clearance at the inlet and exhaust vents (the right and left sides of the router).
•
There is approximately 23.25 inches (59.06 cm) of clearance at the front, and 19 inches (48.3 cm) at the back of the router for
