Attach ground cable
Use a single M4x0.7 screw 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-oxident 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.
2 Attach the bracket “ears” to the rack or cabinet posts, using two screws for each bracket. Ensure the screws are
tightened firmly. The example here shows the mounting on the I/O side, but either side can be used.
Step Task
1 Take the (1) M4x0.7 screw from the package.
2 Cut cable to desired length. Cable length must facilitate the proper operation of fault interrupt circuits. Dell
Force10 recommends using of the shortest cable route allowable.
