RS-232 Terminal Port (ASYN0)
The RS-232 ASYN0 terminal port is used to connect the switch to a
management device for initial configuration and switch management tasks.
This allows the switch software to be accessed from a terminal, a PC running
terminal emulation software, or from a remote location via a modem
connection. You can also use ASYN0 to establish a network connection from a
remote site using SLIP and a modem.
ASYN0 has a DCE female socket. 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 DTE pin layout
is shown in the following figure and table.

Gigabit Interface Converters (GBICs)
GBICs are removable gigabit port converters for switches that have GBIC bays.
GBICs allow users to interchange port types to meet changing network
requirements. GBICs can be purchased when a switch is purchased, or can be
purchased separately as needed.
The following GBICs have been tested and approved for use with AT-9800
Series switches:
■Allied Telesis AT-G8T, 1000BASE-T, 100m
■Allied Telesis AT-G8SX, 550m SX
■Allied Telesis AT-G8LX10, 10km LX
■Allied Telesis AT-G8LX25, 25km LX
■Allied Telesis AT-G8LX40, 40km LX
■Allied Telesis AT-G8LX70, 70km LX
For the latest list of approved GBICs, contact your authorised Allied Telesis
distributor or reseller, or visit www.alliedtelesis.com/support/software.
For information on installing GBICs, see the AT-9800 Series Switch Quick
Install Guide.
Any combination of copper and fibre GBICs can be installed in the AT-9812T
and AT-9816GB switches.
Important RX and TX terminal locations on SC fibre GBIC ports are the reverse
of RX and TX terminal locations on fixed SC fibre ports. When looking at an SC
fibre GBIC from the front, the RX terminal is on the left and the TX terminal is
on the right.
GBIC 1000BASE-T Auto-Negotiation
1000BASE-T GBICs support only 1000 Mbps full duplex connections. Although
1000BASE-T GBICs will participate in auto-negotiation processes, they will
only advertise 1000 Mbps. Half duplex, 10BASE-T, and 100BASE-TX modes are
not supported.
While 1000BASE-T GBICs will auto-negotiate at the copper Ethernet level, the
ports will behave as if in fixed 1000 Mbps full duplex mode. This is because the
SERDES connection used by GBIC ports makes the auto-negotiation invisible
to the switch, and so prevents a successful link negotiation.
When a 1000BASE-T GBIC is inserted into a GBIC slot, the port’s auto-
negotiation capability is disabled. This means that the port speed may not be
set to "auto-negotiate". If the port has been configured to auto-negotiate (by
default or by command) prior to the GBIC’s insertion, then this configuration is
overridden for as long as the GBIC remains in place.

Memory Options
The following memory expansion options are available:
■CompactFlash Card
■Content Addressable Memory (CAM)
■Dual In-line Memory Modules (DIMMs)
CompactFlash Card
AT-9800 Series switches have a CompactFlash slot on their rear panel.
CompactFlash cards increase the flash memory available for file storage.
CompactFlash files can be manipulated using the command line interface. Any
type of data, including releases, patches, GUIs and configurations can be stored
on CompactFlash cards. However, release, patch, and GUI files cannot be run
directly from CompactFlash. These files must be loaded into either NVS or
on-board flash. CompactFlash functionality is supported by Software Version
2.5.1 and later.
Important Anyone with a compliant reader can read CompactFlash cards so
do not keep sensitive data on them.
The following CompactFlash cards have been approved for use with AT-9800
Series switches:
■AT-CF032A-00 32MB CompactFlash card
■AT-CF128A-00 128MB CompactFlash card
For the latest list of approved CompactFlash cards, contact your authorised
Allied Telesis distributor or reseller, or visit www.alliedtelesis.com/support/
software.
Important AT-9800 Series switches support only CompactFlash cards with a
maximum hardware access time of 100 nanoseconds.
Installing and removing a CompactFlash card
CompactFlash cards can be inserted into the CompactFlash slot at any time. It
takes approximately two seconds for an inserted card to be initialised. The
following CLI message confirms that the card has been inserted:
Info (1106257): Compact flash card inserted.
The following message confirms that the card is ready to use:
Info (1106268): Compact flash card initialisation successful.
The following message means that the CompactFlash card is not compatible
with the switch:
Info (3106300): Compact flash card initialisation
unsuccessful.
Important When data is being written to or read from the card, the
CompactFlash Activity LED on the rear panel of the switch is green. Do not
remove the card when it is active or you will corrupt the data. Wait until the LED
is off before ejecting the card.

Testing a CompactFlash card
To display information about the basic state of a CompactFlash card, including
card size, file count and serial number, insert the card and enter the command:
show cflash
To display cluster ranges on a card, insert the card and enter the command:
show cflash test
The following figure is an example of output from the show cflash test
command when no test is running.
To test a card, insert the card and enter the command:
enable cflash test start=startnumber end=endnumber
where startnumber and endnumber are positive integers within a cluster range.
The endnumber must be higher than the startnumber. Cluster ranges are
displayed in the output of the show cflash test command.
The test software will read the file allocation table and display a list of free
sectors. Sectors can be tested as single sectors or as a range. The test will consist
of a write/read/verify cycle.
To stop the test, use the command:
disable cflash test
To display the test status while a test is in progress, use the command:
show cflash test
The following is example output from the show cflash test command when a
test is running.
Error messages are displayed when a file write fails. Failure could be due to the
card being removed or an error in the card.

C613-03059-00 REV F
Content Addressable Memory (CAM)
AT-9800 Series switches ship with 40 k-entries of CAM, as standard. This
memory is divided into three fixed allocations:
■8 k for MAC address tables
■4 k for VLAN entries
■28 k for all other L2/L3 tables , such as IP route entries
CAM can be expanded through the purchase and installation of lineCAM.
LineCAM is a 192 k-entry plug-in module that extends the Layer 2/Layer 3
forwarding database from 40 k to 232 k. One lineCAM module can be installed
in each AT-9800 series switch.
When lineCAM is installed, the memory allocations are:
■8 k for MAC address tables
■4 k for VLAN entries
■220 k for all other L2/L3 tables
LineCAM can be ordered as a pre-installed item when purchasing a switch, or
can be purchased separately. For more information, contact your authorised
Allied Telesis distributor or reseller.
To check how much CAM is installed, use the command:
show switch
For information on installing CAM, see “Restricted Procedures” on page 31.
Dual In-line Memory Modules (DIMMs)
Synchronous DRAM for AT-9800 Series switches is provided by a single
DIMM. Two memory sizes are supported, 128 MBytes and 256 MBytes.
Warning Only Allied Telesis supplied DIMMs are tested and approved for use
with AT-9800 Series switches. Using DIMM that has not been tested and
approved may cause unreliable operation and will invalidate the switch’s
warranty.
To check how much DIMM is installed, use the command:
show switch
For information on installing DIMMs, see “Restricted Procedures” on page 31.

Cables for RJ-45 Ethernet LAN Interfaces
A twisted pair cable with four pairs and RJ-45 connectors must be used for
10BASE-T/100BASE-TX/1000BASE-T (10/100/1000BASE) connections.
Caution Do not plug a phone jack into an RJ-45 switch port because you could
damage the switch. Use only twisted pair cables with RJ-45 connectors.
Pin assignments Each pair of twisted pair cables is identified by related colours. For example,
one wire might be red, and the related wire would be red-and-white stripe. An
RJ-45 connector must be fitted to both ends of the cable. The following diagram
shows RJ-45 connectors and the pin layout.

Redundant Power Supply (RPS)
Redundant Power Supply (RPS) units enhance network reliability by
providing backup coverage for switch Power Supply Units (PSUs).
AT-9800 Series switches have an RPS connector on the rear panel. The
connector allows the switch to be connected to an AT-RPS9000 system. The
AT-RPS9000 must be purchased separately.
The AT-RPS9000 is a chassis that holds up to four removable AT-PWR9000
power units. Each AT-PWR9000 power unit can provide redundant power to
one AT-9812T or AT-9816GB switch. When fully loaded, the AT-RPS9000
chassis can support up to four switches.
The AT-RPS9000 chassis has two AC power inlets. Each inlet supplies two
bays, and therefore two AT-PWR9000 units and two switches.
Rear panel of the AT-RPS9000.
The pin layout and functions of the RPS connector on the rear panel of AT-9800
Series switches are shown in the following figure and table.

AT-TFTP Server
This section explains how to access and use the AT-TFTP Server. Use AT-TFTP
server to download software upgrades to your switch, and transfer
configuration files to and from your switch.
To use AT-TFTP Server, follow these steps.
1. If AT-TFTP Server has not yet been installed:
Install it now from the AT-9800 Series Switch Documentation and Tools
CD-ROM.
Select 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
AT-TFTP 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 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 RS-232 terminal port (ASYN0), use 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.

Using Windows Terminal and Windows
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
1. Start the program in Windows by doing one of the following:
• Select Programs > Accessories > Communications > HyperTerminal.
• Double-click the Hypertrm.exe icon.
2. In the Connection Description dialog box:
• Enter a name for the connection, such as Admin.
• Select an icon from the scrollable list and click the OK button.
