Installing the Dell ReadyRail System
The ReadyRail rack mounting system is provided to easily configure your rack
for installation of your switch. The ReadyRail system can be installed using
the 1U tool-less method or one of three possible 1U tooled methods (two-
post flush mount, two-post center mount, or four-post threaded).
1U Tool-less Configuration (Four-post Square Hole or Unthreaded Round Hole)
1 With the ReadyRail flange ears facing outward, place one rail between the
left and right vertical posts. Align and seat the rear flange rail pegs in the
rear vertical post flange. In Figure 1-19, item 1 and its extractions illustrate
how the pegs appear in both the square and unthreaded round holes.

2 Align and seat the front flange pegs in the holes on the front side of the
vertical post. See Figure 1-19, item 2.
3 Repeat this procedure for the second rail.
4 To remove each rail, pull on the latch release button on each flange ear and
unseat each rail. See Figure 1-19, item 3.
