Installing the mounting brackets, chassis rails, and grounding
cable (for the S5830-52SC)
The S5830-52SC switch provides one front mounting position (near the network ports) and one rear
mounting position (near the power modules), and two grounding points (one primary grounding point
with a grounding sign, and one auxiliary grounding point). You use the primary grounding point in most
cases. If the primary grounding point fails or is not suitable for the installation site, use the auxiliary
grounding point.

Attaching the mounting brackets and chassis rails to the switch chassis
1. Align the mounting brackets with the screw holes in the rear mounting position (see Figure 14 ) or
front mounting position (see Figure 15 ).
2. Use M4 screws (supplied with the switch) to fix the mounting brackets to the chassis.
3. If the mounting brackets are in the rear mounting position, align the chassis rails with the screw
holes at the front of the side panels (see
Figure 14 ). If the mounting brackets are in the front
