Installing the Dell ReadyRails System
The ReadyRails rack mounting system is provided to easily configure your rack for installation of your
S4820T switch. The ReadyRails 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).
1 With the ReadyRails 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 4-1 , step 1 and
its extractions show how the pegs appear in both the square and non-threaded round holes.
