Ground cable

NOTE: For an AC-powered switch, 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 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 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.
NOTE: The S4112-ON Series has a DC power source rated -40 to -72 VDC, 6A
minimum, Tma=40C, and an altitude operation of 3048m. The power cable is
10AWG, 16A minimum, with a 72V minimum rating.
The ground cable is not included. To properly ground the chassis, Dell EMC recommends a
one- or two-hole lug, M4 hole size. The ground lugs must be a UL-recognized, crimp-type
lug.
