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.

x900 Series Switch and SwitchBlade®x908

■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.

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.

Applying Power to the Switch
Power supply bays are in the rear of the switch. Depending on the model, the
switch may have a PSU, FOM, or blanking plate over a power supply bay.
Connecting an AC power supply
Follow these instructions to connect one of the following to an AC power supply:
■an AT-PWR01, AT-PWR02, or AT-PWR05 AC PSU
■an x900-12XT/S switch
Warning The AT-PWR01 AC PSU has a fuse rating of 250V, 5 A for FH101 and
FH102.
Warning The AT-PWR01 AC PSU has double pole/neutral fusing. Electric
shock is possible since there are dual primary fuses, one on the phase circuit and
one on the neutral circuit. If the neutral opens, the phase may still be live.
Warning When x900-24 units are connected with VCS stacking cables (XEM-
STK-CBL) ensure that all the PSUs are appropriately grounded. This is to avoid
large circulating ground currents that could damage the stacking cables. To
achieve this ensure that:
■AT-PWR01 AC is grounded by the 3-pin AC power connector
■All grounding points are at the same ground level. That is, all power
connectors share a common power distribution unit.
Warning For x900-24 models, when using an AT-PWR01 AC power supply and
an AT-PWR01 DC power supply in the same switch, then the ground-terminal of
the DC power connector must be connected to the same ground as the AC
ground pin of the AC power connector.
If this is not possible, then you must ground the AT-PWR01 AC only, and leave
the AT-PWR01 DC power connector ungrounded. In this case, as a safety
precaution, ensure that the rack is also grounded.
Warning For SwitchBlade x908 AC models the grounding stud on the rear of
the unit is for supplemental grounding only. The system must be supplied by a
grounded 3 wire AC source through the power supply cord.
Warning When SBx908 devices are connected with VCS stacking cables (either
HS-STK-CBL or XEM-STK-CBL), each individual stack member chassis must be
additionally grounded by using the rear grounding-terminal on each device. In
order to avoid large circulating ground currents, the wires of each grounding
cable must be 18AWG or thicker.

x900 Series Switch and SwitchBlade®x908

1. Plug the AC power cord that is provided into the power inlet on the PSU.
2. Connect the power cord to the main power source.
3. On the AT-PWR05, set the Run/Standby switch to Run.
4. Check that the PSU LED on the front panel of the switch is lit green. If the
LED does not light, refer to the Hardware Reference for troubleshooting
information.
Connecting a DC power supply
Follow these instructions to connect an AT-PWR01 or an AT-PWR05 DC PSU
to a 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 In order to avoid damaging the PSU, make sure that the PSU terminals
are wired to the correct polarity.
Warning When x900-24 units are connected with VCS stacking cables (XEM-
STK-CBL) ensure that all the PSUs are appropriately grounded. This is to avoid
large circulating ground currents that could damage the stacking cables. To
achieve this ensure that:
• AT-PWR01 DC is grounded at the GND terminal. In order to avoid
large circulating ground currents, the wires of each grounding cable
must be 18AWG or thicker.
• All grounding points are at the same ground level. That is, all power
connectors share a common power distribution unit.
Warning When mounting one or two AT-PWR01 DC PSUs to a grounded rack,
ensure that the ground level of the rack and the DC power connector are the
same.
Warning For x900-24 models, when using an AT-PWR01 AC power supply and
an AT-PWR01 DC power supply in the same switch, then the ground-terminal of
the DC power connector must be connected to the same ground as the AC
ground pin of the AC power connector.
If this is not possible, then you must ground the AT-PWR01 AC only, and leave
the AT-PWR01 DC power connector ungrounded. In this case, as a safety
precaution, ensure that the rack is also grounded.

Connecting to the Switch
All x900 Series switches and the SwitchBlade x908 can be configured using the
Command Line Interface (CLI) and the Graphical User Interface (GUI).
The procedure and command syntax varies depending on whether the switch is
running the AlliedWare®operating system or the AlliedWare Plus™ operating
system.
Before configuring the switch, you must make some basic connections explained
in the following procedures:
■“Using the AlliedWare Plus Operating System CLI” on page 17
■“Using the AlliedWare Plus Operating System GUI” on page 20
■“Using the AlliedWare Operating System CLI” on page 22
■“Using the AlliedWare Operating System GUI” on page 24
Before starting these procedures, ensure that the switch is connected to a
power supply and receiving power.
Using the AlliedWare Plus Operating System CLI
Depending on the model, an ASYN0/CONSOLE and/or ETH0 port is on the
front of the switch for installation and maintenance.
Note that AlliedWare Plus does not have a default IP address configured on the
ETH0 port. If you want to connect via the ETH0 port using Telnet on your PC
you must connect via the ASYN0/CONSOLE port to configure an IP address on
the ETH0 port before you connect to the ETH0 port to use Telnet on your PC.
1. To use the ETH0 port, you must first assign an IP address to the port.
Log in via the ASYN0/CONSOLE port as described in steps 2 and 3 below,
then enter the following commands:
awplus>enable
awplus#configure terminal
awplus(config)#interface eth0
awplus(config-if)#ip address <address/mask>
where <address/mask> is an IP address and mask in slash notation, for
example 192.168.242.242/24.
Physically connect the ETH0 port to a terminal or PC, and check that the
port’s LEDs are lit. This means a link has been established between the port
and the PC. For NEBS compatibility, the cable must be shielded and
grounded at both ends, especially if permanently connected.

x900 Series Switch and SwitchBlade®x908
18
When x900-24XT, x900-24XT-N, x900-24XS, or SwitchBlade x908
switches are connected to form a virtual chassis stack (VCS), the ETH0
port has additional operational functions. See the Hardware Reference for
more information.
From the terminal or PC, Telnet to the IP address of the ETH0 port.
2. To use the ASYN0/CONSOLE port, physically connect it to the
terminal or PC with the RJ-45 DB9 cable that is supplied. For NEBS
compatibility, the cable must be shielded and grounded at both ends,
especially if permanently connected.
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: None
For information about terminal emulation, see Using Windows Terminal and
HyperTerminal in the Hardware Reference.
3. Log in at the prompt.
If using the ASYN0/CONSOLE port, the login prompt is displayed after the
switch has booted. If not, press the Enter key two or three times.
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 upon successful login.
4. Change the password.
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 following commands:
awplus>enable
awplus#configure terminal
awplus(config)#username manager password <password>

Installation and Safety Guide

5. Configure the switch.
Refer to the AlliedWare Plus™ Operating System Software Reference for
detailed information about configuring the software.
For online help, type ? after:
• the prompt, to list all commands available in the command mode you
are in
• one or more parameters, to list parameters that can come next in the
partial command
• one or more letters of a parameter, to list matching parameters
To complete a keywords, press the Tab key after part of the command. If
only one keyword matches the partial command, the CLI fills in that
keyword. If multiple keywords match, it lists them.
6. Save the configuration.
Save the current configuration as the default startup configuration by using
the commands:
awplus>enable
awplus#copy running-config startup-config
Alternatively, you can save the current configuration with a different file
name and then set the switch to load this file when it restarts by using the
commands:
awplus>enable
awplus#copy running-config <filename>.cfg
awplus#configure terminal
awplus(config)#boot config-file <filename>.cfg
