Connecting the grounding cable to the chassis
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.
HP 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
To use auxiliary grounding point 2, you must prepare a grounding cable yourself.
To connect the grounding cable to a chassis grounding point, for example, the primary grounding point:
Choose a grounding point.
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.
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
