The 5720 Series switch can be attached to a standard 19-inch equipment rack, in either of
the following ways:
Four-post rack, using the mounting
kit provided.
Two-post rack, using mounting
brackets (not provided) to attach the front or the middle of the switch to the
posts.
To attach a switch to a two-post rack, a four-post rack or a cabinet, follow these
steps.
Take care to load the rack so that it is not top-heavy. Start installing equipment at the
bottom and work up.
Four-Post Rack Mount
A four-post rack-mounting kit is included in the box with your switch. The kit
contains an instruction sheet, along with the following components:
Two mounting brackets, known
as inner member in the instruction sheet. These pieces attach
directly to both sides of the switch housing.
Two slider assemblies, one
for each side of the switch. Each slider assembly consists of an outer piece
that is secured to the rack and a sliding rail to which you will attach the
corresponding mounting bracket. These pieces are known on the instruction
sheet as the outer member and intermediate
member.
Mounting ears - Black rack
ears with a thumb screw in the middle (2 count)
Black mounting ear screws (6
count)
To attach your switch to a four-post rack, follow these steps:
Separate the inner sliding rails
from the outer rails by extending the rails and pulling the disconnect latch.
Note which direction the sliding rails slide from the outer rails for correct
installation.
Separating the Inner
Sliding Rails by Pulling the Disconnect Latch
Attach the outer rail (bracket) to the rack, securing it with the
M5 screws.
Attaching the Outer
Rail to the Rack
Attach the inner rail to a side of the switch using the M4 screws.
If you are using the 1U
long rack ears (already attached to the inner rail): Ensure that the
rack ear is flush with the either the front or the rear panel of the
unit and continue to step 4.
Front
Installation: Attaching the Inner Rail
If using the 1U or 2U
short rack ears, attach one to the side of the unit using the #6-32
screws, so that the rack ear is flush with either the front or the rear
panel of the unit.

Repeat steps 2
and 3 for the other side of the device.
Insert the switch into the rail
kit. To install the switch in the front of the rack, slide the switch into the
outer rails in the front of the rack.
Inserting the
Switch into the Front of the Rack
To install the switch in the rear of the rack, slide the switch into the
outer rails in the rear of the rack.
Inserting the
Switch into the Rear of the Rack
Secure the switch to the rack using the thumb screws on the mounting ears.

with Thumb Screws
Two-Post Rack Mount
You can attach your switch to a two-post rack in either of two configurations:
Front mount
Mid-mount
The side of the switch has different sets of holes for attaching mounting brackets in
either configuration.
Brackets for a two-post mount are not included in the box with your switch. However,
they can be ordered separately using part number XN-2P-RKMT299.
To attach your switch to a two-post rack, follow these steps:
On one side of the switch, attach one of the short mounting brackets
to the switch housing.
Attaching a
Short Mounting Bracket (Ear): Middle of Switch
Use four small mounting screws (provided) to attach the bracket to the
switch.
Attach the other short mounting bracket to the other side of the switch housing,
as you did in step 1.
Attach a long mounting bracket to one side of the switch housing and
to the rack post.
Position the long bracket
over the holes between the front and the middle of the switch. Orient it
so that its flange (ear) rests against the rack post.
Attaching a
Long Mounting Bracket: Front of Switch
Attaching a
Long Mounting Bracket: Middle of Switch
Use four small mounting screws (provided) to attach the bracket to the
switch.
Secure the long bracket to the rack post. (Rack-mounting screws are not
provided.)
Repeat step 3 to attach the other long bracket on the other side of the
switch.
Tilting the switch slightly, lift it into the rack so that the mounting brackets
align with the rack posts.
If the switch cannot be tilted (because other
equipment is mounted directly above and below), remove one or both short
mounting brackets from the switch. Lift the switch into position, secure the
flanges (ears) on the long brackets to the rack posts, and then reattach the
short brackets.
Secure the flanges (ears) on both
sides of the switch to the rack posts, using screws that are appropriate for the
rack. (Rack-mounting screws are not provided.)
Verify that the switch is level and is firmly attached to the rack.
If your switch comes with installed AC power supplies, skip to the topic Turn on the Switch.
If your switch does not have an installed power supply, install one or two power
supplies using the instructions in Replace Internal AC Power Supplies.
