Install Guide

Ground lug assembly

Before you install the switch into a rack, install the ground (GND) lug assembly.

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

recommends grounding your switch with a dedicated ground wire. You can order an AC ground lug separately.

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

ground lug kit ships in a plastic bag that is placed with the other accessories inside the shipping box. The ground lug

bracket screws ship attached to the switch. Before you install the DC switch in the dual-tray, attach the ground lug and

bracket to the switch using the included screws and then attach the DC ground wire to the ground lug.

The switch includes two installed M4 screws on the lower-left side of your switch. The DC switch also includes an assembled UL-certified

GND lug with bracket, which is packaged separately. The AC switch does not include the UL-certified GND lug. If any parts are missing,

contact your Dell EMC sales representative.

The ground cable is not included. To properly ground the switch, Dell EMC recommends a one- or two-hole lug, M4 hole size. The

grounding 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 ground lug assembly with an anti-oxidant compound before crimping. Also, bring any unplated mating

surfaces to a clean finish and coat with an anti-oxidant before mating. Plated mating surfaces must be clean and free

from contamination.

1. Remove the two installed M4 screws from the lower-left side of your switch.

NOTE:

Keep these screws.

2. Remove the bracket assembly from the shipping bag.

3. Measure and cut a length of ground wire sufficient to reach between the system-installed ground lug assembly and your rack ground

point.

4. Crimp the ground cable to the ground lug assembly.

a) Coat the bare end of the wire with an anti-oxidant compound.

b) Insert the end of the wire into the ground lug.

c) Crimp the ground lug end.

5. Clean the bracket and lug surfaces thoroughly, and apply an anti-oxidant solution to the mating surfaces.

6. Attach the switch ground lug assembly to the switch.
