rails:

Insert two screws (12-24 or 10-32, depending on rack type) through the holes in one of the front
rack-mount brackets and into the threaded holes in the back rack-mounting rail (see

Figure 2-4
b.
Repeat for the front rack-mount bracket on the other side of the switch.
Tip
If the chassis exceeds the 1-RU space on the low side of the rack, you may have difficulty installing other
equipment. In this situation, loosen the screws on the front and back rails of the chassis and raise it to
the top of the RU space by pushing the chassis up until it cannot go any further. Then retighten the screws
while keeping the chassis in the elevated position.
