2 Installing the extension rail kit
WARNING!
The rail kit is shipped with the slide rail inserted into the guide rail, but the slide rail might slide out of
the guide rail due to its smooth surface and gravity. When taking out or installing the rail kit, use both
hands to hold the rail kit horizontally to avoid bodily injury caused by the rail kit.
2.1
Attaching the front mounting brackets and slide rails to the switch
Select either of the following options based on the airflow design at the installation site to attach the
front mounting brackets and slide rails to the switch:
•
Install the front mounting brackets at the port side of the switch and the slide rails at the power
module side of the switch.
•
Install the front mounting brackets at the power module side of the switch and the slide rails at
the port side of the switch.
Figure 2 shows the installation positions on the chassis for front mounting brackets and slide rails.

The procedures for the two options are similar. The following procedure installs front mounting
brackets at the port side and slide rails at the power module side on an S6520X-54QC-EI switch.
1. Wear an ESD wrist strap and make sure the strap makes good skin contact and is reliably
grounded.
2. Align the four installation holes in the wide flange of a front mounting bracket with the screw
holes at the port side of the chassis and then use M4 screws to secure the front mounting
bracket to the chassis.
3. Align the four installation holes on the slide rail with the screw holes at the power module side of
the chassis and then use M4 screws to secure the slide rail to the chassis.
The position of air vents on the side panel varies by device model. For good ventilation of the
chassis, do not block the air vents when installing slide rails.
4. Repeat the above two steps to attach the front mounting bracket and slide rail to the other side
of the chassis.
