Step 5 Stabilize the switch in the rack by attaching the front rack-mount brackets to the front rack-mounting rails:

a.Insert two screws (12-24 or 10-32, depending on rack type) through the cage nuts and the holes in one of the front rack-mount brackets and into the threaded holes in the rack-mounting rail. This procedure is the same as that for the Cisco Nexus 5020 switch (Figure 2-10 on page 2-14).

b.Repeat for the front rack-mount bracket on the other side of the switch.

Proper Grounding Practices

Grounding is one of the most important parts of equipment installation. Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you properly ground systems during installation, you reduce or prevent shock hazards, equipment damage due to transients, and data corruption. Table 2-5lists some general grounding practice guidelines.
