With the nonport side flush with the rear posts in a recessed position. A recessed position allows a
more gradual bend in the fiber-optic cables connected to the switch and less interference in the aisle
at the front of the rack.

Note that if chassis depth (L) is less than 40.64 cm (16 in.), the chassis will not fit into a rack with a
maximum depth of 81.28 cm (32 in.) using the universal four-post rack kit. The maximum rack depth for
a chassis less than 40.64 cm (16 in.) is 81.28 cm (32 in.) minus the difference between the chassis depth
and 40.64 cm (16 in.). For example, a chassis with a depth (L) of 35.56 cm (14 in.) is 5.08 cm (2 in.)
smaller than 40.64 cm (16 in.), so it will install into a rack with a maximum depth of 81.28 cm (32 in.) -
5.08 cm (2 in.) = 76.2 cm (30 in.).
