4220 Series
provides multiple options for mounting or installing the switch.
Mount Options
You can mount or install the device in the following ways:
All 4220 Series support
mounting as a standalone unit on a flat surface, such as a table top. Use the
rubber feet included with the device to secure the device on the surface. No
other equipment is required for table installation
All 4220 Series support
mounting in a standard two-post rack or four-post rack. Rack mounting ears are
included with the device.
Additionally, the 4220-8X, 4220-4MW-8P-4X, 4220-12P-4X, and the 4220-48T-4X models
support wall-mounting and under-the-table mounting. Anchors and wood screws are
included with the device.
Mount the Device on a
Table
4220 Series switches provide four self-adhesive rubber pads for mounting on
tables or other flat surfaces. The pads keep the switch from scratching the
supporting surface and help ensure adequate airflow around the switches when they
are mounted on top of one another. You can safely place up to four switches on top
of one another.
Caution
Do not place other
equipment on top of table-mounted switches.
To mount a switch on a table - or any firm, flat surface - follow these steps.
Carefully separate the four
rubber pads that are provided
Apply the pads to the underside
of the switch by placing a pad at each corner, ensuring that all corners are
aligned. Table Mount: 4220 Series shows the locations for attaching the rubber mounting feet
on the switch.

Note
Models 4220-12P-4X, 4220-12T-4X,
and 4220-4MW-8P-4X support silent mode operation at temperatures up to 35°C (95°F).
Silent mode requires 1 RU of free space above the switch. Stacked switches do not
have 1 RU of free space between them, and might not run in silent mode. Fans
function normally if the temperature is between 35°C (95°F) and 50°C (122°F).
Install the Device in a
Rack
The 4220 Series can be installed in a four-post rack,
using just the two front posts or two back posts. This procedure uses a two-post
mounting kit, which accommodates rack posts 3 inches or 6 inches wide.
The two-post rack mount kit XN-2P-RMKIT-008 is required for models 4220-24T-4X, 4220-24P-4X, 4220-4MW-20P-4X, 4220-8MW-40P-4X, 4220-48P-4X, and 4220-48T-4X.
The two-post rack mount kit XN-2P-RMKIT-009 is required for models 4220-8X,
4220-12P-4X, 4220-12T-4X, and 4220-4MW-8P-4X.
The rack mount kit contains an instruction sheet, along with the following
components:
Mounting ears (2 count)
Mounting ear screws (8
count)
Rack mounting ears can support two configurations: flush- and mid-mount.
Take care to load the rack so that it is not top-heavy. Start installing equipment at
the bottom and work up.
To attach a switch to a rack, follow these steps.
Attach a mounting bracket to each side of the switch, using the
screws provided. Align each mounting bracket so that the flange (ear) faces the
front of the switch to flush-mount, or faces the rear of the switch to
mid-mount.
The following figures illustrate how to attach the mounting
ears for two common mounting options.
Note
Do not block the air vent
on the top of the unit. Leaving a space between units ensures adequate
airflow.
Flush-Mount:
Attaching mounting ears to models 4220-8X, 4220-4MW-8P-4X,
4220-12P-4X, and 4220-12T-4X
Flush-Mount:
Attaching mounting ears to models 4220-4MW-20P-4X, 4220-8MW-40P-4X,
4220-48P-4X, 4220-48T-4X, 4220-24P-4X, and 4220-24T-4X
Mid-Mount:
Attaching mounting ears to models 4220-8X, 4220-4MW-8P-4X,
4220-12P-4X, and 4220-12T-4X
Mid-Mount: Attaching
mounting ears to models 4220-4MW-20P-4X, 4220-8MW-40P-4X, 4220-48P-4X,
4220-48T-4X, 4220-24P-4X, and 4220-24T-4X
With the mounting brackets attached, position the switch between the vertical
rack rails of the 19-inch rack.
Fasten the switch securely to the rack rails using four
customer-supplied rack screws. Ensure that the threaded length of the screws is
within 4 to 5 cm.
The following figures illustrate how to attach the switch
to the rack for two common mounting options.
Flush-Mount: Mounting
in a Two- or Four-Post Rack for models 4220-8X, 4220-4MW-8P-4X,
4220-12P-4X, and 4220-12T-4X
Flush-Mount: Mounting
in a Two- or Four-Post Rack for models 4220-4MW-20P-4X, 4220-8MW-40P-4X,
4220-48P-4X, 4220-48T-4X, 4220-24P-4X, and 4220-24T-4X
Mid-Mount: Mounting in
a Two- or Four-Post Rack for models 4220-8X, 4220-4MW-8P-4X,
4220-12P-4X, and 4220-12T-4X
Mid-Mount: Mounting in
a Two- or Four-Post Rack for models 4220-4MW-20P-4X, 4220-8MW-40P-4X,
4220-48P-4X, 4220-48T-4X, 4220-24P-4X, and 4220-24T-4X
Mount the Device on a Wall
The 4220-8X,
4220-12P-4X, 4220-12T-4X, and 4220-4MW-8P-4X switch models are constructed so that they can be mounted
on a wall, and require wall mount kit 908775-10. Ensure that the wall is strong
enough to support the weight of the switch and the attached cables.
Note
Orientation for wall mounting is
limited. The front end of the switch must be facing down, and the power inlet must
be facing up when mounting a switch to the wall.
To mount a switch to the wall, follow these steps.
Use the two holes in each short
mounting ear to mark the places on the wall to mount the switch. Each mounting
ear has two mounting holes, so be sure to make four marks. Be sure to position
the marks so that the switch is level when it is mounted.
Drill the holes and attach the
brackets using four wood screws and four anchors that are included in the
accessory kit, which can be ordered separately.
Mount the switch on the wall by
screwing a provided wood screw through each hole in the wall-mounting ears into
the anchors. Ensure that all screws are securely fastened and that the switch is
firmly attached to the wall.

wall for models 4220-8X, 4220-4MW-8P-4X, 4220-12P-4X, 4220-12T-4X
Mount the Device Under a Table
The 4220-8X,
4220-12P-4X, 4220-12T-4X, and 4220-4MW-8P-4X switch models are constructed so that they can be mounted
under a table, and require wall mount kit 908775-10. Ensure that the table is strong
enough to support the weight of the switch and the attached cables.
Note
Models 4220-12P-4X, 4220-12T-4X, and 4220-4MW-8P-4X support silent mode operation
at temperatures up to 35°C (95°F). Silent mode requires 1 RU of free space above the
switch. Fans function normally if the temperature is between 35°C (95°F) and 50°C
(122°F).
To mount a switch under the table, follow these steps.
Using the two holes in each short
mounting ear, mark the places under the table to mount the switch. Each mounting
ear has two mounting holes, so be sure to make four marks.
Drill a hole at each mark.
Insert a provided anchor into
each hole, if an anchor is needed. Gently tap each anchor with a hammer, if
necessary, to ensure that it is inserted tightly.
Mount the switch under the table
by screwing a provided wood screw through each hole in the mounting ears into
the anchors. Ensure that all screws are securely fastened and that the switch is
firmly attached to under the table.
