Dell PowerEdge 860 - Installing the Mounting Rails in the Rack

12 Rack Installation Guide
Installing the Mounting Rails in the Rack
Installing the RapidRails Mounting Rails
1 At the front of the rack cabinet, position one of the RapidRails mounting rails so that its
mounting-bracket flange fits between the marks or tape you placed (or numbered location)
on the vertical rails (see Figure 1-5).
The top mounting hook on the front mounting-bracket flange should enter the top hole
between the marks you made on the vertical rails.
2 Push the mounting rail forward until the mounting hooks enter their square holes, and then
push down on the mounting-bracket flange until the mounting hooks seat and the push
button pops out and clicks (see Figure 1-5).
3 At the back of the cabinet, pull back on the mounting-bracket flange until the mounting
hooks enter their square holes, and then push down on the flange until the mounting hooks
seat and the push button pops out and clicks.
4 Repeat step 1 through step 3 for the mounting rail on the other side of the rack.
5 Ensure that the mounting rails are mounted at the same vertical position on both sides
of the rack.
