Selecting a Site
Before you install the switch, review the following considerations about its
location.
■AT-8948, x900-48FE, and AT-9900 switches require an ambient temperature
from 0ºC to 50ºC (32ºF to 122ºF).
■AT-9924Ts, x900-24X 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.
■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 doors to accommodate cords and cables.
■Ensure easy access to the switch’s power and cable connections.

Installing the Switch
You can install the switch on a level surface, such as a desktop or bench, or in a
standard 19-inch rack. The switch is heavier at the rear than at the front.
Therefore 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 the
Documentation and Tools CD-ROM or 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
• 4 sets of rack-mount screws and nuts, and a suitable screwdriver
To install a DC version of the PSU, you need an appropriate DC power
source, DC supply cable, ring connectors, and a crimp tool.
■Prepare the cabinet in a suitable location
Follow guidelines described in “Selecting a Site” on page 5 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.
■If you have an optional expansion module for the AT-9924Ts or x900-24X
switches, install it in the switch first.
Refer to the Expansion Module Installation Guide for the x900-24X Series Switch
for details.
Warning Both AC and DC versions of this equipment must be earthed through
the power cables provided.

Rack-mount procedure
1. Ensure the rack has sufficient space for the switch and its cables. For the
switch’s requirements, see “Selecting a Site” on page 5.
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 and remove the rubber feet.
It may be helpful to temporarily remove the 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.
5. Mount the switch into the rack from the front, and tighten the 4
rack-mount screws.
Two people are required at this point. One person can lift the switch into
the rack and attach it to the front rails while the second person safely
supports it from the rear.

Applying Power to the Switch
The switch has two bays in the rear. Your switch comes with one pre-installed
power supply unit (PSU). Depending on the model, the switch also has one
fan-only module (FOM) in the other power supply bay or one blanking panel
over the power supply bay.
AC Power Supply
Important information for service personnel:
■CAUTION: double pole/neutral fusing
■the rating of fuses FH101 and FH102 is 250V, 5A (AT-PWR01 only)
Procedure for AC Power Supply
To apply power to the PSU, plug the AC power cord that is provided into the
power inlet on the faceplate of the PSU. Then connect the power cord to the
main power supply.
DC Supply Cable and Power Supply
Supply cable specifications:
■three-core cable is required
■minimum core size: 3.3mm2(12 AWG) high strand count copper wire
■minimum cable rating: 600V, 90 degrees C
Power supply specifications:
■40 to 60V, 48V nominal
■supports either positive grounded or negative grounded operation
■a 15Amp certified/listed circuit breaker is required for circuit protection

Procedure for DC Power Supply
Only trained and qualified personnel should connect a DC power supply.
For centralised DC power connection, the switch should be installed in
restricted access areas only (such as dedicated equipment rooms or
equipment closets) in accordance with Articles 110-16, 110-17, and 110-18 of
the National Electrical Code, ANSI/NFPA 70.
Warning Ensure that the power supply cable is not live before starting.
1. Remove the transparent protective terminal cover.
2. Strip the supply cable wires to expose 7.5mm (0.31in.) of bare conductor.
Terminate the wire with a nylon insulated solderless ring tongue terminal,
JST FN5.5-5 or equivalent, using a crimp tool.
3. Connect the ground wire to the ground terminal. Use the diagram on the
rear panel of the switch to identify terminals. Tighten the terminal to
between 2.4 and 4.0 Nm (21.3 and 35.4 lbf in).
Caution Check that the PSU terminals are wired to the correct polarity.
You will damage it if you incorrectly connect it.
4. Connect the positive feed to the + (positive) terminal and the negative feed
to the - (negative) terminal. Tighten the terminals to between 2.4 and
4.0Nm (21.3 and 35.4 lbf in).
5. Ensure there are no exposed cable strands.
6. Replace the cover. You must replace the transparent plastic terminal cover
before continuing.
7. Secure the supply cable to the rack framework or a similar object to ensure
that connections are isolated from any force applied to the cable.
8. Ensure the circuit breaker is off for the supply circuit and the Run/Standby
control on the PSU. Use a small diameter pin to press and release the Run/
Standby control so that it is not pushed in (which is the Off position).
9. Connect the supply cable wires to the circuit breaker.
10. Turn on the PSU by pushing in the Run/Standby control with a small
diameter pin.
11. Confirm that the switch is receiving power.
Check that at least one of the PSU LEDs on the front panel of the switch is
lit green. If no LEDs light, refer to the Hardware Reference for
troubleshooting information.

Connecting the Switch
AT-8948, x900-48FE, AT-9924Ts, and x900-24X switches can be configured with
the Command Line Interface (CLI). AT-9900 switches can be configured with
either the CLI or the Graphical User Interface (GUI).
Before configuring the switch, you must make some basic connections explained
in the following procedure. Before starting the procedure, ensure that the
switch has at least one power supply unit installed and operating. The other bay
must have another PSU or fan-only module in it, or a blanking plate over it,
depending on the switch model.
Using the CLI to configure a switch
1. Physically connect the terminal or PC to the ASYN0 port on the front
panel of the switch.
For AT-8948, AT-9924Ts, AT-9900, and x900 switches, use the RJ-45 DB9
cable that is supplied.
2. Set communication parameters on your terminal or terminal emulation
program to the following:
• bit rate: 9600
• data bits: 8
•parity:None
• stop bits: 1
• flow control: Hardware
For information about terminal emulation, see Using Windows Terminal and
HyperTerminal in the Hardware Reference.
3. Check the power supply.
For AC models, ensure that the switch is receiving power (PWR LED is lit
green).
For DC models, ensure that the Run/Standby switch is in the On or Run
position and that the switch is receiving power (PWR LED is lit green).
4. Log in.
After the switch has booted, the login prompt is displayed. If not, press the
Enter key two or three times.
