Installation Guide
QX-S6600 Series Ethernet Switches
I. Attaching the mounting brackets and chassis rails to the chassis
For QX-S6648XP-6Q and QX-S6648XT-6Q, four screws are required for install a mounting
bracket at the port side. For QX-S6632QP, three screws are required.
To attach 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 3-8) or front mounting position (see Figure 3-9).
2) Use M4 screws (supplied with the switch) to attach the mounting brackets to the
chassis.
3) Align the chassis rails with the rail mounting holes in the chassis:
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 3-8).
If the mounting brackets are in the front mounting position, align the chassis rails with

the screw holes at the rear of the side panels (see Figure 3-9).
4) Use M4 screws (supplied with the switch) to attach the chassis rails to the chassis.
 NOTE:
Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.
II. Connecting the grounding cable to the chassis
CAUTION:
The primary grounding point and auxiliary grounding point 1 are located on the left side panel. If you use one of
these grounding points, you must connect the grounding cable to the grounding point before you mount the
switch in the rack.
