Installation Guide
QX-S6600 Series Ethernet Switches
 NOTE:
NEC recommends that you use the primary grounding point or auxiliary grounding point 1 because the

grounding cable and grounding screw that come with the switch are suitable only for these two grounding
points.
To use auxiliary grounding point 2 on QX-S6632QP, prepare a grounding cable yourself.

To connect the grounding cable to a chassis grounding point, for example, the primary
grounding point:
1) Choose a grounding point.
2) Unpack the grounding cable and grounding screws. You can use the cable and screws
shipped with the switch only for connecting to the primary grounding point or auxiliary
grounding point 1.
3) Align the two-hole grounding lug at one end of the cable with the grounding holes of
the grounding point, insert the grounding screws into the holes, and tighten the screws
with a screwdriver to attach the grounding lug to the chassis, as shown in Figure 3-8.
