Selecting a Site
Before you install the switch, review the following considerations about its
location.
■AT-8948, x900-48FE, x900-48FS, and AT-9900 switches require an ambient
temperature from 0ºC to 50ºC (32ºF to 122ºF).
■AT-9924Ts, x900-12XT/S, x900-24XT, x900-24XT-N, x900-24XS, and
SwitchBlade x908 switches require an ambient temperature from 0ºC to
40ºC (32ºF to 104ºF).
■There should be adequate airflow around the switch and its vents.
■The site should be dust-free and without moisture.
■Humidity can be from 5% to 80% non-condensing.
■You need a reliable and earthed (grounded) power supply source, preferably
dedicated and filtered.
■Cabling must not be exposed to sources of electrical noise, such as radio
transmitters, broadband amplifiers, power lines, electric motors, and
fluorescent fixtures.
■Switch ports are suitable for intra-building connections, or where
non-exposed cabling is required.
■Related network devices can be connected to the switch but cannot exceed
maximum cable lengths specified in the Hardware Reference.
■You may need to remove cabinet doors from the equipment rack to
accommodate cords and cables.
■Ensure easy access to the switch’s power and cable connections.
■The SwitchBlade x908 should only be installed in locations where access to
the system is controlled. The SwitchBlade x908 is not intended for home
use. If installed in a school, it should only be installed in a location restricted
to service personnel.

Installation and Safety Guide

Installing the Switch
Ports on the switch are suitable only for connections within buildings (intra-
building) and with cables unexposed to the outside.
You can install the switch on a level surface, such as a desktop or bench, or in a
standard 19-inch rack. Some switches are heavier at the rear than at the front.
Use the brackets supplied with the switch when rack-mounting because they are
designed to fully support the weight.
Before you begin
■Read the safety information.
For your well-being and that of the equipment, read the safety information in
this document. You can also download this document from
www.alliedtelesis.com/support/software.
■Verify the package contents if you have not already done so.
See “Package Contents” on page 4. If any items are damaged or missing,
contact your authorised distributor or reseller.
■Gather necessary tools and equipment:
• Phillips #2 screwdriver to loosen the blanking plate, if any.
• Rack-mount screws and nuts, and a suitable screwdriver. The
SwitchBlade x908 requires eight sets of screws and nuts. All other
switches required four sets.
• For DC installations, you need an appropriate DC power source, DC
supply cable, ring connectors, and a crimp tool for screw terminal style
connectors or appropriate connectors for the PSU model.
■Prepare the cabinet in a suitable location
Follow guidelines described in “Selecting a Site” on page 6 to choose an
appropriate location and modify the rack as necessary.
■Because the switch is deep, we recommend two people mount the switch in
the rack and tighten the screws.
Preparation for NEBS
For Network Equipment Building System (NEBS) installations of the x900-24XT-N,
do the following to ensure rack-mounted installations are earthed:
■Remove non-conductive coatings, such as lacquer and enamel, from the rack
rail where hardware will contact it. Remove coatings from unplated
connectors, braided strap, and bus bars, and bring them to a bright finish.
Coat them with an antioxidant before connecting them. During installation,
thread-forming screws with star washers may be used for this purpose.

■All bare conductors must be coated with an appropriate antioxidant
compound before making crimp connections.
Warning Both AC and DC versions of this equipment must be earthed through
the power cables provided.
On a level surface
1. Ensure the area has sufficient space for the switch and its cables.
If you have not already done so, review considerations in “Selecting a Site”
on page 6.
2. Unpack the switch.
3. Fit rubber feet, if supplied.
All models except the SwitchBlade x908 ship with rubber feet. They stop
the switch from slipping and protect the surface from scratches. The
x900-12XT/S switch has four feet. All other models have five feet. Using the
screws provided, screw the rubber feet in the holes on the underside of the
switch. Use the following diagram to locate the screw holes. For the
x900-12XT/S, use positions 1, 2, 3, and 5.
4. Place the switch in the desired location for operation.

In a 19-inch rack
1. Ensure the rack has sufficient space for the switch and its cables. For the
switch’s requirements, see “Selecting a Site” on page 6.
2. Install cage nuts at the front of the rack so they are ready for the rack-
mount screws in the following steps.
3. Unpack the switch.
It may be helpful to temporarily remove any PSU or FOM so that the switch
is lighter and easier to manipulate during installation. For more information,
see the Removable Power Supply and Fan Installation Guide.
4. Screw one bracket to each side of the switch using the M4 screws provided.
On the x900-12XT switch, you can use the alternative set of holes on the
rack mount bracket to mount the switch further back in the rack.
For NEBS ensure the rack and hardware have been pre-treated, as
described in “Preparation for NEBS” on page 7.
