To attach the slide rails to the rack:
1. Identify the slide rail installation position in the rack.
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 a rear rack post. Use user-supplied
M6 screws to attach the slide rail to the post (recommended torque: 30 kgf-cm). See
Figure2-37 .
4. Repeat the preceding steps to attach the other slide rail to the other rear rack post.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.

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.
CAUTION:
To rack-mount the S9850-4C switch by using 2U high mounting brackets and slide rails, use
four M6 screws and four cage nuts to attach each mounting bracket to the rack, as shown in
Figure2-42 and Figure2-43 .
5. One person performs the following operations:
