4.2.3 Adjusting Mounting Rails and Cable Management Rails
WARNING: Do not attempt to adjust rails without assistance. Do not attempt to adjust rails while
equipment is installed in the enclosure. Do not attempt to use rails without screws installed (6 per rail).
The 4 mounting rails are pre-installed to accommodate equipment with a mounting depth of 30 inches (762 mm). Do
not adjust the mounting rails unless your equipment requires a different mounting depth. The front and rear sets of
rails can be adjusted independently in ¼-inch (6 mm) increments.

Each rail is connected to the
enclosure with 6 screws - 1 pair
at the upper beam

, 1 pair at

Remove the screws fastening
each of the rear mounting rails to
the enclosure. (If adjustment of
the front rails is required, you can
also remove the screws from the
front rails.)

Slide the mounting rails to the
desired depth and reattach them
using the screws you removed in
Step

. The rail attachment
points are numbered

to help
you align each pair of rails at the

The depth of the 2 cable
management rails can be
adjusted using the same method.
