Attaching the mounting brackets and chassis rails to the chassis
IMPORTANT:
M4 screws are used to secure the mounting brackets and chassis rails to the switch. As a best
practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten M4 screws.
To attach the mounting brackets and chassis rails to the chassis:
1. Place the wide flange of a mounting bracket against a side panel of the chassis and align the
round holes in the wide flange of the front mounting bracket with the screw holes in the side
panel. Then use M4 screws (provided) to attach the mounting bracket to the chassis.
To install the mounting brackets at the port side, see Figure2-9, Figure2-10, and Figure2-11.

To install the mounting brackets at the power supply side, see Figure2-12, Figure2-13, and

Figure2-14.
2. Determine the chassis rail installation position based on the mounting bracket installation
position.
3. Place the chassis rail against the side panel of the chassis and align the installation holes in the
chassis rail with rail mounting holes in the chassis. Then use M4 screws (provided) to attach the
chassis rail to the chassis.
For installation of chassis rails of rack mounting rail kit A (long slide rails), see

Figure2-12.
The chassis rails of rack mounting rail kit B (super-short slide rails) support narrow-spacing

installation and wide-spacing installation. Select narrow-spacing (as shown in
and Figure2-13) or wide-spacing (as shown in
based on the distance between the front and rear rack posts.
4. Follow the same procedure to attach another mounting bracket and chassis rail to the opposite
side.
