Figure 6. Installing the S4048–ON in a Front-Rack Configuration

Attaching the Ground Cable (Optional)

The S4048–ON requires one M4x0.7 screw for attaching a ground cable to the chassis.

To properly ground the chassis, Dell Networking recommends a 6 AWG one-hole lug, #10 hole size, 63"

spacing. The one-hole lug must be a UL-recognized, crimp-type lug.

NOTE: The rack installation ears are not a suitable grounding point.

CAUTION: Grounding conductors must be made of copper. Do not use aluminum conductors.

NOTE: Coat the one-hole lug with an anti-oxidant compound prior to crimping. Bring any unplated

mating surfaces to a shiny finish, and coat with an anti-oxidant prior to mating. Plated mating

surfaces must be clean and free from contamination.

Cut the ground cable to the desired length. The cable length must facilitate the proper operation of

fault interrupt circuits. Dell Networking recommends using the shortest cable route allowable.

Attach the one-hole lug to the chassis using an M4x0.7 screw with a captive internal tooth lock

washer, as shown. Torque the screw to 20 in-lbs.
