You can place either end of the USG chassis towards the cabinet door. In this manual, the rear
panel of the USG is towards the cabinet door.
Procedure
Step 1 Install mounting ears on the chassis.
Use a Phillips screwdriver to fix the mounting ears to both sides of the chassis with M4
screws, as shown in
Figure 2-32 Installing the mounting ears on the chassis
Step 2 Install cabinet guide rails and floating nuts.
Both the L-shape guide rails and adaptive ones are applicable. Install the guide rails based on
the type of guide rails obtained.

adjust the distance between the front and rear installation angle gauges (mounting
bars/side posts) until meeting the requirements for installing the rail.
The position for the USG in the cabinet is well arranged.
Ensure that the USG is 1 U of clearance from any devices above and below and 150 mm
of clearance from any devices on the right or left.
The device to be installed is staged near the cabinet for convenience.
From the rear perspective of the chassis, the cooling wind of the USG flows in on the left
and front, and is exhausted on the right. When a USG and a device whose cooling wind
flows in on the right and is exhausted on the left are installed in the same cabinet,
adequate space must be reserved between them to avoid thermal cycles.
