2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.
3. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use
screws (user supplied) to attach the slide rail to the rack, as shown in
Figure 10 .
4. Repeat the preceding step to attach the other slide rail to the rack post on the other side.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.

Mounting the switch in the rack
This task requires two people.
To mount the switch in the rack:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Verify that the mounting brackets and chassis rails have been securely attached to the switch
chassis.
3. Verify that the slide rails have been correctly attached to the rear rack posts.
4. Attach cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as
the slide rails.
5. One person supports the bottom of the switch, aligns the chassis rails with the slide rails on the rack
posts, and then slides the chassis rails slowly along the slide rails until the mounting brackets are
flush with the rack posts.
6. Another person uses screws (user-supplied) to attach the mounting brackets to the rack.
To secure the switch in the rack, make sure the front ends of the slide rails reach out of the chassis
rails.
