x900 Series Switch and SwitchBlade x908  
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  
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

Installation and Safety Guide  
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.

Installation and Safety Guide  
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.

Installation and Safety Guide  
All x900 Series switches and the SwitchBlade x908 can be configured using the  
®
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  
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>

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

x900 Series Switch and SwitchBlade x908  
Using the AlliedWare Plus Operating System GUI  
Follow this procedure to establish a connection to an x900 or x908 series  
switch, so you can use the GUI to configure the switch.  
1. Select a PC to use and identify its subnet.  
You can browse to the switch from any PC running a supported operating  
system with a supported browser with JavaScript enabled. You may need to  
install and run the latest Java Runtime Environment that you can download  
from the Sun site so your browser can support the GUI Java applet.  
2. Connect the PC to the switch.  
Use an Ethernet cable to connect an Ethernet card on the PC to any of the  
switch ports. You can browse to the router through any VLAN as long as  
you give it an IP address. These instructions assume you are using vlan1. All  
switch ports belong to vlan1 by default.  
3. Access the CLI from the PC as described in “Using the AlliedWare Plus  
Operating System CLI” on page 17.  
4. Assign an IP address to connect to the GUI using these CLI commands:  
awplus>enable  
awplus#configure terminal  
awplus(config)#interface vlan1  
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.  
5. Configure your switch with a default gateway using these CLI commands:  
awplus(config-if)#exit  
awplus(config)#ip route 0.0.0.0/0 <gateway-address>  
where <gateway-address> is an IP address for your gateway device.  
Note that you do not need to define a default gateway if you browse to the  
switch from within its own subnet.

x900 Series Switch and SwitchBlade x908  
Using the AlliedWare 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.  
1. To use the ETH0 port, physically connect it to the 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.  
The default configuration contains the following commands:  
enable ip  
add ip int=eth0 ip=192.168.242.242  
Set the PC to an IP address in the 192.168.242.0 subnet, and then establish  
a Telnet session to 192.168.242.242.  
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: Hardware  
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.

Installation and Safety Guide  
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 set password command.  
5. Configure online help.  
To use online help you must first configure the help file by using one of  
these commands:  
For AT-8948, x900-48FE, x900-48FE-N, x900-48FS, and AT-9900 switches,  
use:  
set help=<filename>.hlp  
For AT-9924Ts, x900-24XT, x900-24XT-N, and x900-24XS switches, use:  
set install=preferred help=help-filename  
Help files have an HLP extension. To see the help files on your switch, use  
the command:  
show system  
6. Configure the switch.  
®
Refer to the x900 Series Switch AlliedWare Operating System Software  
Reference for more information about configuring the software.  
Alternatively, if you do not know the command syntax, use any of the  
following to help you:  
To display a list of help topics, use the help command.  
To display help on a specific topic, use the help <topic> command.  
To display a list of valid options, type a question mark or press the Tab  
key at the end of a partial command.  
To complete a parameter after you have typed enough letters to  
uniquely match the desired one, press the Tab key.  
7. Save the configuration.  
Save your configuration to a new file by using the command:  
create config=<filename>.cfg  
Then set the switch to load this file when it restarts by using the command:  
set config=<filename>.cfg
