Attach ground cable
The S55 is shipped with 1 10-32 screws for attaching a ground cable to the chassis. The cable itself is not
included. Dell Force10 recommends a 6AWG one-hole lug, #10 hole size, 63" spacing (not included in
shipping) to properly ground the chassis. 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.
Follow these steps to connect the ground cable to the chassis.
NOTE: Coat the one-hole lug with an anti-oxidant compound prior to crimping.
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.
