Attaching the Ground Cable

To attach the ground cable to the chassis, use a single M4x0.7 screw.
The cable itself is not included with the S4810–ON. To properly ground the chassis, Dell Networking
recommends using a 6AWG one-hole lug, #10 hole size, 63" spacing (not included in shipping). The one-
hole lug must be a UL recognized, crimp-type lug.
NOTE: The rack installation "ears" are not suitable for grounding.
CAUTION: Grounding conductors must be made of copper. Do not use aluminum conductors.
To connect the ground cable to the system, follow these steps.
NOTE: Coat the one-hole lug with an anti-oxidant compound prior to crimping. Also, bring any un-
plated 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. Take the one M4x0.7 screw from the package.
2. Cut the cable to the desired length. The cable length must facilitate proper operation of the fault
interrupt circuits. Dell Networking recommends using the shortest cable route allowable.
