2. Mark the slide rail installation position on the rack posts.
Make sure the positioning tab at the bottom of the slide rail is inserted into the lowest square

hole within the 2 RU space on a rack post. The installation holes on the slide rail are aligned
with the square holes in the rack post. See callouts 1 and 2 in Figure2-15.
Make sure the slide rail installation positions are at the same height on the four rack posts

so that the switch can be placed on the slide rails evenly.
3. Install cage nuts in the marked square holes within 2 RU at the same height on the rack posts,
as shown by callout 3 in Figure2-15. Each rack post requires four cage nuts.
a. Insert the lower ear of a cage nut into the corresponding installation hole.
b. Compress the upper and lower ears of the cage nut to lead the upper ear through the hole.
4. Perform the following tasks as shown by callout 4 in Figure2-15:
a. Align the installation holes on the two ends of a slide rail with the cage nuts on the front and
rear rack posts.
b. Compress the slide rail, making sure the positioning tabs at both ends of the slide rail are
inserted into the lowest square holes within the 2 RU space on the rack posts.
c. Use M6 screws to secure the slide rail to the rack posts.
TIP:
Install a screw in each mounting hole of the slide rail to ensure its weight bearing capacity.
5. Repeat step 4 to install the other slide rail.
