Introduction to the cable guiding frame

Fixing the floating nuts

a

Mark the positions where floating nuts are to be 
installed, and install four floating nuts on both sides of 
the rack.

Part 1 (cable 
guiding frame)

2. Place the chassis's 
mounting ears and 
cabling rack U-shaped 
slots over the screws, 
tighten the screws at the 
bottom.

1.Hang the screws of 
the mounting ears on 
the chassis to the rack 
loosely.

3. use screws to tighten 
the top of the chassis.

1. Remove one screw for installing PGND cable 

before 

installing the chassis in the cabinet

.
