Chapter 2 Installing the Cisco Nexus 3000 Series Switches
Installing the Switch
c. Attach the front-mount bracket using four M4 screws. Tighten the screws to 12 in-lb (1.36 Nm).
d. Repeat Steps 1a, 1b, and 1c with the other front rack-mount bracket on the other side of the switch.
Step 2 Install the rear rack-mount gu ides on the chassis as follows:
a. Align the two screw holes on a rear rack-mount bracket to the middle two screw holes in the
remaining six holes on the side of the chass is. If you are aligning the guide t o holes that are near
the port connections end of the chassi s, see Callout 3 in Figure 2-1. Otherwise, see Callout 7 in
Figure 2-1.
b. Attach the guide to the chass is using two M4 screws. Tight en the screws to 12 in-lb (1 .36 N m).
See Callout 4 or 8 in Figure 2-2.
c. Repeat Steps 2a and 2b with the other rear rack-mount bracket on the other side of the switch.
Step 3 Install the slider rails o n the rack or cabinet as follows:
a. Determine which two posts of the ra ck or cabinet you should use for the slider rails. Of the four
vertical posts in the rack or cabin et, two will be used for the fro nt mount brackets attached to
the easiest accessed end of th e chassis, and the other two pos ts will have the slider rails.
a. Position a slider rail at the desired level on the back side of the rack and use two 12-24 screws
or two 10-32 screws, depending on the rack thread type, to atta ch the rails to the rack. See
Figure 2-3.
Note For racks with square holes, you might need to position a 12-24 cage nut behind each mounting
hole in a slider rail before using a 12-24 screw.
