Selecting a Site
Before you install the switch, review the following considerations about its
location.
■The switch requires an ambient temperature range of 0 º C to 40º C
(32º F to 104º F).
■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 connection to intra-building or 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 to accommodate cords and cables.
■Ensure easy access to the switch’s power and cable connections.

6 AT-8600 Series Switch
Installing the Switch
Ports on the switch are suitable only for connections within buildings (intra-
building) and with cables unexposed to the outside.
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.
■Choose a suitable operating location.
You can install the switch either in a 19-inch rack, on a flat bench, or against
a wall. Follow the guidelines in “Selecting a Site” on page 5 to choose a
location.
■To ensure rack-mounted installations are earthed for compatibility with
Network Equipment Building System (NEBS), do the following:
• Remove non-conductive coatings, such as lacquer and enamel, from the
rack rail where hardware will contact it. Also remove coatings from
unplated connectors, braided strap, and bus bars, and bring them to a
bright finish. Then 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.

Installation & Safety Guide 7
Procedure
1. If you have any optional expansion modules, install them first.
The AT-8600 Series switches support the AT-A45/xx, AT-A46, AT-A47, and
AT-A65 expansion modules. Install them by following the instructions in the
relevant guide:
•AT-A65 Expansion Module Installation and Safety Guide for the AT-A65
module only.
•AT-A45/xx Series, AT-A46, and AT-A47 Expansion Modules Installation Guide
for the other expansion modules.
These instructions ship with individual expansion modules, and are also
available from www.alliedtelesis.com/support/software.
Note that if you insert or remove a module when the switch is already
powered on, you must restart the switch before you can use the module.
2. Place the switch in its operating location.
If installing the switch in a rack:
• Remove the rubber feet on the bottom of the switch with a flat-head
screwdriver.
• Attach the two rack-mounting brackets to the switch with the screws
provided in the rack-mount kit.
3. Mount the switch in the rack using rack-mount screws
Note that the screws are not provided with the switch.
4. Install any SFPs.
You can install optional SFP (Small Form-factor Pluggable) modules into the
AT-8648T/2SP.
Warning Do not look into the optical ports of SFP cables or transceivers.
Invisible laser radiation may be emitted from disconnected fibres or
connectors.
In both SFP ports, the SFP transceivers must be inserted with the release
lever hinge at the bottom. Use the following figure as a guide.

8 AT-8600 Series Switch
.
Slide the transceiver into the SFP socket, and firmly press it until it engages.
To remove it, first release it by gently pulling the release lever, and then pull
it out of the socket. Never force a transceiver into or out of a socket.
When an SFP is installed into one of the two SFP ports, that SFP port takes
precedence over its corresponding 10/100/1000T port. When the SFP is
removed, the 10/100/1000T port is once again active.
5. Check the supply voltage and the switch’s rated voltage
AT-8600 Series switches are fitted with a universal main power supply that
functions from100–240 VAC and 50–60 Hz.
Specific power supply requirements for the model are on the rear or
underside of the switch. If the supply is outside the acceptable range, the
switch may not operate or may be damaged.
6. Apply AC power to the switch.
Plug the power cord into the AC power connector. This is on the switch’s
rear panel, as shown in the below figures.

Connecting the Switch
Some configuration is necessary to enable the switch’s advanced switching
capabilities. This is achieved via the Command Line Interface (CLI). On the
AT-8624T/2M, you can also use the Graphical User Interface (GUI).
Using the CLI to configure a switch
1. Connect a terminal or PC to the terminal port (ASYN0).
Using the supplied RS-232 DB9 serial straight-through cable, connect your
terminal or PC to the RS-232 port:
• For the AT-8624T/2M and AT-8624PoE, the RS-232 port is on the front
panel.
• For the AT-8648T/2SP, the RS-232 port is on the back panel.
2. Set the communication parameters on your terminal or terminal emulation
program to:
• Bit rate: 9600
• Data bits: 8
•Parity:None
• Stop bits: 1
• Flow control: None
3. Log in.
After the switch has booted, the login prompt appears. If it does not
appear, press the Enter key several times.
When the switch starts for the first time, it automatically creates an
account with manager privileges. The account has the login name manager
and the password is friend.
At the login prompt, enter the login name and password:
Login: manager
Password: friend
The switch’s command prompt appears, and you can now use the CLI to
configure the switch.
4. Change the password.
A manager account left with the default password is a serious security risk.
Remember the new password as there is no way to retrieve it if it is lost.
To change the account password, use the set password command.

Installation & Safety Guide 11
5. Configure online help.
Before using online help, you must configure the help file by using the
command:
set help=<filename>.hlp
Help files have an HLP extension. To see a list of help files loaded on your
switch, use the command:
show files=*.hlp
6. Configure the switch.
Refer to the 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
For information about configuring the software, see the AT-8600 Series Software
Reference.
Using the GUI to configure the AT-8624T/2M switch
This section describes how to establish a connection to the AT-8624T/2M switch
through the GUI so you can configure it before installing it in your LAN.
1. Select a PC to use and identify its subnet.
You can browse to the switch from any PC that is running a supported
operating system with a supported browser installed. JavaScript must be
enabled. If you are using a toolbar or plug-in on your browser to block pop-
ups, disable it while using the GUI. The GUI displays detailed configuration
options and information in pop-up windows.

12 AT-8600 Series Switch
2. Connect the PC to the switch.
Use an Ethernet cable to connect an Ethernet card on the PC to any one of
the switch ports.
You can browse to the router through any VLAN, as long as you give that
VLAN an IP address. These instructions assume you are using vlan1. All
switch ports belong to vlan1 by default.
3. Access the switch’s command line interface.
Access the CLI from the PC, as described in the previous section, “Using
the CLI to configure a switch” on page 10.
4. Enable IP.
enable ip
5. Assign the vlan1 interface an IP address in the same subnet as the PC.
add ip interface=vlan1 ip=ipaddress mask=mask
6. Save the configuration and set the switch to use it on bootup.
create config=your-name.cfg
set config=your-name.cfg
7. On the PC’s web browser, bypass the HTTP proxy server, if necessary.
8. Point your Web browser at IP address for vlan1.
9. At the login prompt, enter the user name and password.
User Name: manager <the default>
Password: friend
The System Status page is displayed. Select options from the sidebar menu
to configure and manage the switch.
For context-sensitive online help, click the Help button at the top of the
