Assembling the Rails
Assembling the Rails
This section describes how to assemble the rails for your rackmount
cabinet. Your rail kit contains two different-length front rail mounts
(for an illustration, see page 2); be sure to use the rail length that is
appropriate for your rack/cabinet.
If you want the optic connections in the front and the power connections in
the back, reverse the placement of the front and rear rails in the instructions
below. However, if you do this, you will not be able to get the bezel on the
cabinet.
1. Measure the depth of the cabinet from the inside of the front rail
to the inside of the rear rail.
2.
Depending upon the depth of the cabinet, assemble one front rail
(short or long) and one rear rail together so that the combined
rails (outside edge to outside edge) are equal to the depth of the
cabinet.
Do not use a front (long) rail and a rear rail together if the depth is under
22 inches as this could restrict air flow around the switch.
3.
Using two #8 32x3/8” flat-head screws, attach one 2-hole nut bar
to hold the front and rear rails together. See the figure below.
Do not completely tighten the nut bars screws to the rails but tighten
them enough to hold the rails together.
