6 Installing the Hardware
Install chassis into rack or cabinet
Attach a 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.
2 Attach the brackets to the sides of the chassis on either side, using four 
screws for each bracket.
Attach the bracket so that the “ear” faces to the outside of the chassis.
Step Task
1 Dell Force10 recommends that one person hold the Z9000 chassis in 
place while a second person attaches the brackets to the posts.
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.
