3. Tighten the two thumb screws and rack screws.

To remove the switch from the rack or cabinet, press in the two side-release bars on the switch at the same time and slide the

switch forward.

Ground cable

NOTE:

For AC-powered switches, although the third conductor of the AC power cord provides a ground path, Dell EMC

recommends grounding your switch with a dedicated ground wire.

NOTE: For DC-powered switches, the only way to safely ground your switch is to attach a dedicated ground wire.

Depending on the type of switch, to attach a ground cable to the switch, you need M3 or M4 screws.

The switch ships with one of the following two configurations:

● One threaded hole using an M3 screw.

● Two threaded holes using one of the two M4 screws.

In both configurations, the ground cable is not included. To properly ground the switch, Dell EMC recommends a one- or two-

hole lug, M3 or M4 hole size. The ground lugs must be a UL-recognized, crimp-type lug.

CAUTION: Grounding conductors

must

be made of copper. Do not use aluminum conductors.

NOTE: Coat the one-hole lug with an anti-oxidant compound before crimping. Also, bring any unplated mating surfaces to a

shiny finish and coat with an anti-oxidant before mating. Plated mating surfaces must be clean and free from contamination.

1. Cut the ground cable (not included) to the desired length. The cable length must facilitate proper operation of the fault

interrupt circuits. Use the shortest cable route allowable.

2. To attach the ground cable, use one of the following:
