A four-post rack-mounting kit (XN-4P-RKMT301 for Extreme 8820-80C or XN-4P-RKMT302
for Extreme 8820-40C) is included in the box with your device. 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 device housing.
Two slider assemblies, one
for each side of the device. 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 device 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
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 unit, 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.

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.

Attach the Device to a Two-Post Rack
You can attach your device to a two-post rack in mid-mount configuration.
Brackets for a two-post mount are not included in the box with your device. However,
a two-post mount kit can be ordered separately using part numbers XN-2P-RKMT299 for
the Extreme 8820-40C or XN-2P-RKMT300 for the Extreme 8820-80C.

To attach your device to a two-post rack, follow these steps:
On one side of the device, attach
one of the short mounting brackets to the device housing.
Attaching a
Short Mounting Bracket (Ear): Middle of Device
Use six small mounting
screws (provided) to attach the bracket to the device.
Attach the other short mounting
bracket to the other side of the device router housing, as you did in step 1.
Attach a long mounting bracket to
one side of the device router housing and to the rack post.
Position the long bracket
over the holes between the front and the middle of the device. Orient it
so that its flange (ear) rests against the rack post.
Attaching a
Long Mounting Bracket: Middle of Device Router
Use six small mounting
screws (provided) to attach the bracket to the device.
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
device.
Tilting the device slightly, lift it into the rack so that the mounting brackets
align with the rack posts.
If the device cannot be tilted (because other
equipment is mounted directly above and below), remove one or both short
mounting brackets from the device. Lift the device 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 device to the rack posts, using screws that are appropriate for the
rack. (Rack-mounting screws are not provided.)
For Extreme 8820-40C, install the
ground lug cables to the rack using an M6 screw and the four screws provided
(grounding screws for 2-post installation shipped with the device in a separate
bag).

If your device comes with installed AC power supplies, skip to the topic: Turn on the Device.
If your device does not have an installed power supply, install one or two power
supplies using the instructions in Install Internal Power Supplies.
