Attaching the mounting brackets, chassis rails, and
grounding cable to the chassis
As shown in Figure2-7 , the switch provides two installation positions on the two sides for mounting
brackets: one near the power supply side and one near the port side. A primary grounding point (with
a grounding sign) and an auxiliary grounding point are available on the switch.

Attaching the mounting brackets and chassis rails to the chassis
1. Attach the mounting brackets to the chassis.
a. Identity the left and right mounting brackets.
The left mounting bracket has an L mark. The right mounting bracket has an R mark.
b. Place the long side of a mounting bracket against its installation position on the chassis.
Align the mounting holes in the mounting bracket with the screw holes in the chassis. Use
the provided M4 screws to attach the mounting bracket to the chassis. As a best practice,
use a torque of 12 kgf-cm (1.18 Nm) to fasten the M4 screws.

To install a mounting bracket near the port side, see Figure2-8 .
−
To install a mounting bracket near the power supply side, see Figure2-9 .
2. Attach the chassis rails to the chassis.
a. Determine the chassis rail installation position based on the mounting bracket installation
positon and the distance between the front and rear rack posts, as shown in
Table2-2 .
