Implementing PoE
The IEEE 802.3af standard, which is the IEEE standard for PoE, describes two
methods for implementing PoE over twisted pair cabling. One method uses the
same strands that carry the network traffic and the other the spare strands.
The PoE implementation on the AT-8624PoE switch transmits power over the
same strands that carry the network traffic (strands 1, 2, 3 and 6). The power
transfer does not interfere with the network traffic. The power and the network
traffic can coexist on the same strands simultaneously.
Powered devices that comply with the IEEE 802.3af standard support both
methods of power delivery. As long as a powered device is compliant with the
standard, it should be able to receive its power from the switch.
AT-TFTP Server
This section provides information on how to access and use AT-TFTP Server.
AT-TFTP Server can be used to transfer configuration files as well as to
download software patches and releases.
To use AT-TFTP Server, follow these steps:
1.
If AT-TFTP Server has not yet been installed.
Install it now from the AT-8600 Series Documentation and Tools CD-ROM.
Choose AT-TFTP Server from the Start > Programs > Allied Telesis >
AT-TFTP Server menu.
2.
To set preferences for the AT-TFTP Server.
Select "Options" from the File menu to display the "Set Preferences" dialog
box.
The "Default file transfer directory" field specifies the directory that ATTFTP Server will read from or write to for file requests that do not include a
directory specification.
To prevent unauthorised access to private directories, enter a path name in
the "Restrict to directory" field. AT-TFTP Server will use only the specified
directory, even if file requests contain references to other directories.
Select "Read only" to prevent files being written to the PC. To use the PC to
archive scripts created using the switch’s CREATE CONFIG command, select
"Read Write".
Make any required changes and click "OK".

3.
To load a file from AT-TFTP Server to the Switch.
On a terminal connected to the switch, type the command:
LOAD METHOD=TFTP FILE=filename SERVER=ipadd DEST=FLASH
where filename is the name of the file to download and ipadd is the IP
address of the PC running AT-TFTP Server.
4.
To save a TFTP Server log.
Select "Save As" from the File menu.
TFTP requests are logged to the AT-TFTP Server main window.

AT-8600 Series
Switch Start-up
This section outlines the log in and start-up procedures for your switch.
Although the switch will perform basic switching operations without being
configured, you will need to go through these log in and start-up procedures if
you wish to configure the switch and access its full switching capabilities.
To log in
Using the supplied RS-232 DB9 straight-through cable, connect your terminal
or PC to the RS-232 Terminal Port. On the AT-8624T/2M and the AT-8624PoE,
the RS-232 Terminal Port is on the switch’s front panel. On the AT-8648, it is on
the rear panel.
Set the communication parameters on your terminal or terminal emulation
program to:
■
Baud rate: 9600
■
Data bits: 8
■
Parity: None
■
Stop bits: 1
■
Flow control: None
See “Using Windows Terminal and Windows Hyperterminal” on page 37 for
more information on configuring emulation software.
After the switch has booted, the log in prompt appears. If the log in prompt
does not appear, press [Enter] two or three times.
When the switch boots for the first time it automatically creates an account
with manager privileges. The account has the log in name “manager” and the
password is “friend”.
At the log in prompt, enter the log in name and password.
Log in: manager
Password: friend
The switch’s command prompt appears and you can now configure the switch
using the command line interface.
Change the password as soon as possible. Leaving the manager account with
the default password is a serious security risk. Make sure that you remember
the new password as there is no way to retrieve it if it is lost.
Use the following command to change the account password:
set password
See the AT-8600 Series Software Reference for more information on configuring
the switch.

11
To access help files
Before help is used for the first time, the help files must be defined.
To define the files, enter:
set help=help-filename
where help-filename is the name of a help file stored in flash.
To see a list of files stored in flash, enter:
show file
Help files have an HLP extension.
To display a list of help topics, enter:
help
To display help on a specific topic, enter:
help topic
Alternatively, type a question mark (?) at the end of a partially completed
command to see a list of valid options.
Start-up Procedures
When the switch starts up following either a power cycle or an operatorinitiated reboot (using the RESTART command), a series of start-up messages
is sent to the RS-232 Terminal Port (Figure 4).

is displayed on the terminal connected to the RS-232 Terminal Port and the
switch pauses. If a key is not pressed within a few seconds, the start-up process
will continue and all steps in the sequence will be executed.
C613-03080-00 REV E

Switch Interfaces
This section provides pin assignments for the switch’s RS-232 Terminal Port
and RJ-45 ports, and the Redundant Power Supply (RPS) connector.
RS-232 Terminal Port
The RS-232 Terminal Port is used to connect the switch to a management
device. For management purposes the switch’s software can be accessed from a
terminal, a PC running terminal emulation software, or from a remote location
via a modem connection. You can also use the RS-232 Terminal Port to establish
a network connection from a remote site using SLIP and a modem.
The switch’s RS-232 Terminal Port has a DB9 female connector. This allows the
use of a straight-through cable when connecting the switch to a terminal or PC.
Output from the SHOW ASYN command will, however, still have a DTE
perspective. The internal DTE pin roles are listed in Table 3 on page 14.
See Terminal and Modem Cables on page 20 for more information on
connection options for the RS-232 Terminal Port.

For 10BASE-T/100BASE-TX connections, a twisted pair cable must be used.
Each pair is identified by two different colours. For example, one wire might be
red, and the other red with a white stripe. An RJ-45 connector must be fitted to
both ends of the cable. Figure 6 illustrates the pin layout for RJ-45 connectors.

Loopback Plugs for Testing Switch Interfaces
Loopback plugs are used in conjunction with the Test Facility software to test
the physical interfaces on the switch (see the “Test Facility” section beginning
on page 22 of this Reference, and the Test Facility chapter of the AT-8600 Series
Software Reference). The purpose of a loopback plug is to connect the output
pins on the interface to the input pins so that any data transmitted over the
interface is looped back and received at the same interface.
Gigabit copper interfaces (as found on the AT-A39/T expansion module, and the
AT-8648T/2SP) cannot be looped back. Loopback plugs can only be used in conjunction
with 10/100 Ethernet interfaces.
On interfaces with control signals, these are also looped back. The data
received on the interface is compared with the data transmitted to determine
whether or not the interface is functioning correctly. In order to produce a
comprehensive test report for the interface being tested, most tests performed
by the Test Facility require a loopback plug to be inserted.

Test Facility
This section introduces the Test Facility. The Test Facility is built into all
AT-8600 Series software. For detailed information on operating the Test
Facility, see the Test Facility chapter of the AT-8600 Series Software Reference.
The Test Facility is designed to test the switch’s physical interfaces. Testing
should not be performed while the switch is operational as the presence of a
loopback plug may cause feedback of network traffic. Also, any interfaces
being tested are dedicated to the Test Facility. The Test Facility can be thought
of as a specialised interface module like PPP or Frame Relay.
10/100 Ethernet LAN Port Tests
A loopback plug is required to run the first part of the Ethernet LAN test. See
“Loopback Plugs for Testing Switch Interfaces” on page 22 for details of how to
make a loopback plug. To start an Ethernet interface test, use the command:
enable test int=portn
where n is the Ethernet interface number. The test will run for 4 minutes. Use
the show test command to observe the test progress.
Test results are displayed with the command:
show test
C613-03080-00 REV E

Some common problems and how to solve them
Power LED is off
This can indicate:
■
A loose power cord.
■
A power supply failure.
Perform the following steps in sequence:
Link/Activity LED on
any port is off
1.
Check that the power cord connections are secure.
2.
Check that all switches and circuit protection devices are in the ON position.
3.
Ensure that the supply voltage is within the operational range (110/240
VAC 50/60 Hz).
This can indicate:
■
A loose data cable.
■
The device at the other end of the connection is not working properly or is
turned off.
■
The data cable is not wired correctly.
■
The network administrator has manually disabled the port through the
software.
■
The port’s selected transmission mode does not match that of the attached
device.
Perform the following steps in sequence:
1.
Make sure the data cable connections are secure.
2.
Make sure the device at the other end of the connection is switched on and
working properly.
3.
Check that the data cable is wired correctly.
4.
If you can, log in and check the port status. See “To Log In” on page 12 for
more information on how to log in.
5.
If the port is Enabled, make sure the transmission speed matches that of the
connected device (auto-negotiating, full or half-duplex).
If the port is disabled, someone has used the software to manually disable it. You should
find out why the port was disabled before enabling it.
Fault LED is on
This can indicate:
■
There is a problem with the switch or RPS PSU.
■
The switch or management software is malfunctioning.
■
A hardware fault is preventing switch start-up.
Perform the following steps in sequence:
1.
Check “LEDs on AT-8600 Series Switches” on page 25 for descriptions and
explanations of LED flashing sequences.
2.
Restart the switch by entering the RESTART REBOOT command.

3.
If you were attempting to download software or manage the switch via the
RS-232 terminal Port, check that connections between the Terminal Port and
local terminal or PC are secure.
If you cannot access the switch’s software because of a faulty RS-232
Terminal Port connection, you can still manage the switch via Telnet or
SNMP until the problem is fixed.
4.
Unplug the switch and then plug it in again. If an RPS unit is present, you
will also have to disconnect and reconnect the RPS unit.
5.
Download the latest software release. See the AT-8600 Series Software
Reference for more information on how to obtain the latest software release.
Expansion Options
This section provides an overview of the expansion options for AT-8600 Series
switches. The following expansion options were available when this Reference
was written. See your Authorised Allied Telesis distributor or reseller, or visit
www.alliedtelesis.com/support/software to see if any new options are
available.
Expansion Modules
Expansion modules increase switching capacity by providing a maximum of
two extra ports and by allowing switches to be linked together in stacks. For
the AT-8600 Series, an expansion module with gigabit capacity is available.
Expansion modules in the following list are the only modules that should be
installed into AT-8600 Series switches. Check with your Authorised Allied
Telesis distributor or reseller, or visit www.alliedtelesis.com to see if any new
expansion module models are available.
The expansion module currently available is:
■
AT-A46 10/100/1000BASE-T RJ-45
This expansion module is supported by AT-8000 Series switches as well as
AT-8600 Series switches.
For more information on expansion modules, contact your Authorised Allied Telesis
distributor or reseller, or see the AT-A45/xx Series, AT-A46, and AT-A47 Expansion
Modules Installation Guide. This and other documentation can be found on the
AT-8600 Series Documentation and Tools CD-ROM bundled with your switch.
Adding and removing expansion modules
Hot swap of expansion modules is supported on AT-8624PoE and
AT-8648T/2SP switches. If a module is inserted or removed while the switch is
powered on, the Fault LED flashes 7 times. You must restart the switch to turn
off the flashing LED and make an inserted module ready for operation. Until
the switch is restarted, the output of the show system and show switch port
commands will not reflect the newly inserted or removed expansion module.

Using Windows Terminal and
Hyperterminal
You can use a PC running terminal emulation software as the manager console,
instead of a terminal. There are many terminal emulation applications
available for PCs, but the most readily available are the Terminal and
HyperTerminal applications included in Microsoft Windows 98, 2000, and
XP Professional. In standard Windows installations, HyperTerminal is
available from the Communications submenu.
The key to successful use of terminal emulation software with the switch is to
configure the software and switch with matching communications parameters.
The following procedure can be applied to most terminal emulation programs.
Dialog boxes in the procedure are from Windows 2000 and XP Professional.
To configure Windows HyperTerminal for 2000 and XP Professional
