Step Task (continued) 2 Attach the bracket "ears" to the rack or cabinet posts, using two screws for each bracket. Ensure the screws are tightened firmly. PSU0 PSU1 Rack/Cabinet Post Rack Mounting ears 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. Step Task 1 Take the (1) 10-32 screw from the package. 2 Cut cable to desired length. Cable length must facilitate the proper operation of fault interrupt circuits.
