3 Tighten the two thumb screws and rack screws.

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 one of the included M3 or M4 screws. The switch ships
with one of the following two configurations:
• One threaded hole using an included M3 screw
• Two threaded holes using one of the two included 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 antioxidant compound before crimping. Also, bring any unplated mating surfaces to a shiny
finish and coat with an antioxidant before mating. Plated mating surfaces must be clean and free from contamination.
NOTE: The rack installation ears are not suitable for grounding.
