Figure 61. Securing a rail with a single screw
● If you are installing the rails in a rack that has threaded holes, insert an M4 screw into the smaller of the two center
screw holes at both the front and the rear of the rail. The screw is smaller and will pass through the threaded hole in the
NEMA racks.
● If you are installing the rails in a rack that does not have threaded holes, insert an M5 screw that comes with the chassis
into the larger of the two center screw holes in the rail at the front and rear of the rack.
