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.

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

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.

Installation and Safety Guide
11
When the switch boots for the first time, it automatically creates an
account with manager privileges. The login name for the account is manager
and the password is friend.
At the login prompt, enter the login name and password as follows:
Login: manager
Password: friend
The switch’s command prompt is displayed for you to use the CLI to
configure it.
5. Change the password.
Change the password as soon as possible because a manager account with
the default password is a serious security risk. Remember the new
password because there is no way to retrieve it if you forget it.
To change the account password, use the set password command.
6. Configure the switch.
Refer to the Software Reference for more information about configuring
the software.
7. Configure the switch. If you do not know the command syntax, use any of
