Step 2 Open the front securing plate on both slide-rail assemblies. The front end of the slide-rail assembly has a spring-loaded
securing plate that must be open before you can insert the mounting pegs into the rack-post holes.
On the outside of the assembly, push the green arrow button toward the rear to open the securing plate.

Step 3 Install the slide rails into the rack:
a) Align one slide-rail assembly front end with the front rack-post holes that you want to use.
The slide rail front end wraps around the outside of the rack post and the mounting pegs enter the rack-post holes
from the outside-front.
The rack post must be between the mounting pegs and the open securing plate.
Note
b) Push the mounting pegs into the rack-post holes from the outside-front.
c) Press the securing plate release button, labeled PUSH. The spring-loaded securing plate closes to lock the pegs in
place.
