Install the Z9000 | 21
Attach the Ground Cable
Use a single M4x0.7 screw to attach the ground cable to the system. The cable itself is not included with
the Z9000. To properly ground the system, Dell Force10 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-oxident compound prior to crimping. Also, bring any un-plated
mating surfaces to a shiny finish and coat it with an anti-oxidant prior to mating. Plated mating surfaces must
be clean and free from contamination.
1 Attach the bracket “ears” to the rack or cabinet posts using two screws for each bracket. Ensure the screws are
tightened firmly. The example shows the mounting on the I/O side, but you can use either side.
Step Task
1 Take the one M4x0.7 screw from the package.
2 Cut the cable to the desired length. The cable length must facilitate the proper operation of the fault interrupt
circuits. Dell Force10 recommends using the shortest cable route allowable.
