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.
1.
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.
2.
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.
