The 7720 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.
Note
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 on the disconnect latch.
Note which direction the sliding rails slide from the outer rails for correct
installation.
Separating the Inner
Sliding Rails
Attach the outer rail (bracket) to the rack, securing it with
the M5 screws.
Attaching the Outer
Rail
Attach an inner rail to the side of the device, 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 device using the #6-32
screws, so that the rack ear is flush with either the front or the rear
panel of the device.
Front
Installation: Attaching a Rack Ear
Rear
Installation: Attaching a Rack Ear
Repeat steps 2 and 3 for the other side of the device.
Insert the device into the rail
kit. To install the device in the front of the rack, slide the device into the
outer rails in the front of the rack.
Front
Installation: Inserting the Device
To install the device in the rear of the rack, slide the device into the
outer rails in the rear of the rack.
Rear Installation:
Inserting the Device
Secure the device to the rack using the thumb screws on the mounting ears.

Device
Two-Post Rack Mount
You can attach the 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 the switch. However,
they can be ordered separately using part number XN-2P-RKMT299.
To attach the switch to a two-post rack, follow these steps:
On one side of the switch, attach
one of the short mounting brackets to the device.
For a front mount,
position the bracket over the holes so that the flange (ear) is even
with the front of the device, as shown in the figure below:
Attaching a
Short Mounting Bracket (Ear): Front of Switch
For a mid-mount, position
the bracket so that the flange (ear) is positioned slightly more than
halfway between the front and back of the device, as shown in figure
below:
Attaching a
Short Mounting Bracket (Ear): Middle of Switch
Use four small mounting
screws (provided) to attach the bracket to the device.
Attach the other short mounting
bracket to the other side of the device, as you did in step 2.
Secure the brackets to the rack
posts using rack-mounting screws that are appropriate for the rack (not
provided).
If the switch comes with installed power supplies, skip to the topic: Turn on the Switch.
If the switch does not have an installed power supply, install one or two power
supplies using the instructions in Install Internal Power Supplies.
