AR700 Series Routers
All AR700 Series routers include Ethernet ports, asynchronous ports, and PIC
bays; the AR750S, AR750S-DP and AR770S also have switch ports. PIC bays
add expansion flexibility by allowing the installation of PIC cards, which are
available with additional interfaces, such as ISDN (PRI E1/T1, BRI S/T),
synchronous, or asynchronous ports. The AT-AR745 routers also have an
expansion bay to accommodate a Network Service Module (NSM), which either
directly provides further interfaces, or provides multiple slots where additional
PIC interfaces can be added.
The AR725 and AR745 routers have a dedicated PCI Accelerator Card (PAC)
slot that accommodates special purpose PAC coprocessor cards. PAC cards
provide additional functionality or performance, such as compression or
encryption, through a high performance PCI bus, but do not add extra
interfaces. The AR750S and the AR750S-DP have built-in high performance
encryption processing.
AR700 Series models are distinguished by the number and types of ports and
presence or absence of an NSM bay and/or PCI Accelerator Card (PAC) slot.

AR700 Series Router
PIC bays and NSM The AT-AR745 chassis has two PIC bays. A further four PIC bays can be added
if an AT-AR040 NSM is installed in the NSM bay.
bay
The NSM bay allows one NSM to be installed in the chassis. NSMs either have
fixed ports (e.g., AT-AR041 and AT-AR042 BRI S/T NSMs) or PIC bays (e.g.,
the AT-AR040 4 PIC NSM). For detailed information on NSMs, see the Network
Service Module Hardware Reference.
The PIC bays and the 4-PIC NSM can accommodate combinations of the
following PICs (with a maximum of two E1/T1/PRI cards):
■
■
■
■
AT-AR020 PRI E1/T1 PIC, one primary rate E1/T1 port
AT-AR021(S) BRI-S/T PIC, one basic rate ISDN S/T port
AT-AR021(U) BRI-U PIC, one basic rate ISDN U port
AT-AR023 SYN PIC, one synchronous port with universal 50-way
AMPLIMITE connector
■
■
AT-AR024 ASYN4 PIC, four asynchronous ports with RJ-45 connectors
AT-AR027 VoIP-FXS PIC, two Foreign Exchange Subscriber (FXS) ports
with RJ-11 connectors
Recommendation AT-AR022 ETH PICs and AT-AR026 4ETH PICs are not
recommended for use in NSM PIC bays, as performance of these interfaces is
likely to be reduced and packet loss may occur. When used with an AR745
router, ETH PICs should be installed in the router’s PIC bay 0 or PIC bay 1.
Asynchronous Ports The two asynchronous serial ports can be used as general purpose ports for
terminals, printers or modems. They are effectively identical and can be
independently configured. The default communications settings are:

PAC Slot AT-AR745 routers have a single PAC slot inside the chassis. When installed,
PACs provide hardware-based encryption and or compression capability via a
PCI interface. For information on PACs, including a list of compatible PACs,
Caution PACs should only be installed by authorised service
personnel. Unauthorised opening of the router lid may cause danger of
injury from electric shock, damage to the router, and invalidation of
the product warranty.

The show system command displays the state of the main power supply and
fan, and whether or not the RPS is being monitored. If RPS monitoring is
enabled, it also shows whether an RPS is connected, and the state of its output
voltage and fan.
When a fault occurs in the main power supply or fan, system LEDs on the
AT-AR745’s front and back panels are flashed in a pattern that identifies the
fault. If RPS monitoring is enabled, the system LEDs also flash to indicate
failures in the RPS connection, power supply or fan. Multiple faults are
indicated by cycling through each error code.

Restart with default To restart the router with the default configuration, either press the Reset
button on the front panel of the router, or use the command:
configuration
restart router config=none
This immediately restarts the router with the default configuration specified in
the boot.cfgfile. The factory-loaded default configuration is shown in the
Installation and Safety Guide. If the file has been removed, the router restarts
with no configuration. We recommend leaving boot.cfgunchanged, so that
you can revert to the original configuration if necessary.
To return the router to the previous user configuration, restart the router by
using the command:
restart router
This restarts the router with the startup configuration file previously specified
by the command:
set config=filename
The restart reboot command or a power cycle also reload this user
configuration. For information about configuration files, see the Managing
Configuration Files and Software Versions chapter in the Software Reference.
AT-PWR03 Power Supplies
The AR750S-DP comes with the option of installing one or two AT-PWR03
power supplies. When two are fitted, they must be the same type of current,
either both AC or both DC.
The AR750S-DP should use only the AT-PWR03 power supply. Do not use any
other power supply to power this router.
You can create triggers to execute scripts when specific PSU events occur. For
more information, see the Trigger Facility chapter in the AR700 Series Router
Software Reference.

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 router is to
configure the software and router 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:

Router Start-up
At start-up, the manager can choose to run either the software version stored in
the flash boot block, or the software version in the flash file system specified by
the installation parameters previously set using the set install command.
All code is executed out of system RAM. At power-up the boot code is loaded
from the flash boot block to RAM. The boot code checks the installation
parameters then reloads RAM with the selected temporary, preferred, or default
install version (stored in the flash file system) and runs this code.
The version is uncompressed as it loads to RAM. This may take 10 to 30
seconds. At this point, any required patches are loaded from the flash file
system. Any patch is also uncompressed as it loads to RAM. This procedure
ensures that the code runs at maximum speed, and allows updates to be made
to the code. Updates can be downloaded over the network from a TFTP server
and stored in the flash file system until required at power-up.
To download software onto the router, see the Managing Configuration Files and
Software Versions chapter in the Software Reference.
All router software, patches, and configuration settings are stored as files in
flash memory. Typically, the following files will be present in the flash file
system:
■
The current installed software version. Additional software versions may
also be present.
■
■
The current installed patch, if any. Additional patches may also be present.
The command line help file for the command line interface (CLI). The
command help is stored in a separate text file, with extension .hlp. The
command help file is loaded with a software version.
■
■
The boot configuration script boot.cfg. The boot script contains standard
router commands (executed on start-up to configure the router).
Additional user-defined configuration scripts containing commands to
configure the router for different functions. These scripts are created using
the built-in editor, the add script command (in the Scripting chapter of the
Software Reference), or the create config command (in the Managing
Configuration Files and Software Versions of the Software Reference).
■
Other files required by the system.
Configuration information is stored in flash memory as configuration scripts.
These scripts contain standard router commands. When a configuration
command is entered at the command prompt from a terminal, terminal
emulation program, or Telnet session, the command alters the dynamic
configuration only; this is not saved over a power cycle. To ensure that
configuration changes resulting from such commands are retained across a

power cycle, the dynamic configuration must be saved as a configuration
script, using the create config command.
When the router starts up following either a power cycle or an operator-
initiated reboot (using the restart command), it performs the following
sequence of operations:
1. Perform start-up self tests.
2. Load the flash boot block version as the INSTALL boot into the router’s
RAM.
3. Prompt the manager for changes to the default start-up procedure:
Force EPROM download (Y)?
override the default installation procedure.
4. Check the INSTALL information to determine which version to load and
run, according to the INSTALL parameters, and the manager’s response to
the INSTALL parameters determine which version and patch are loaded
and run.
5. Load the required version specified by the INSTALL parameters from the
flash file system as the main boot.
6. Start the router.
7. Execute the boot configuration script, if one has been configured. (The boot
configuration script is either a configuration file set using the set config
command from the Managing Configuration Files and Software Versions
chapter, or the file boot.cfg file, if there is one.)
A series of start-up messages is sent to asyn0 (the console or terminal port).

Random Access Memory (RAM)
The routers use RAM to run software for router operations, and to store the
router’s dynamic configuration.
The AR725 and AR745 routers have 128 MB of SDRAM on a DIMM and can be
upgraded. Contact your authorised Allied Telesis distributor or reseller for
upgrade options. Other supplier’s DIMMs are not approved, not supported,
and may not function correctly.
Warning DIMMs should be installed by authorised service personnel
only. Unauthorised opening of the router lid may cause danger of
injury from electric shock, damage to the router, and invalidation of
the product warranty.

Battery-Backed RAM (AR725, AR745, AR770S
only)
The AR725 and AR745 have 128 kB of battery-backed SRAM as NVS (non-
volatile storage), and the AR770S has 512 kB. The router can store files such as
logs and configuration scripts in NVS over a power cycle.
Onboard Flash Memory
Flash memory is a nonvolatile reprogrammable memory storage device for
router software versions, allowing upgrades to be remotely loaded from any
WAN or LAN port. Flash memory is also used to store other types of data such
as patches, logs and configurations.
There are two types of flash—onboard flash (flash connected directly to the
router’s PCB and available on all routers), and CompactFlash (flash provided
by removable compact flash cards). All the routers have onboard flash
memory; AR725 and AR745 routers also have a slot for compact flash cards.
Of the router’s onboard flash memory, 1 MB is reserved for the flash boot
version. You can use the rest to store files in the flash file system, such as a
software version file, GUI resource file, configuration scripts and command
line help file. The router also stores system files in the flash file system.
Testing Onboard Flash Memory
There are several ways to check that onboard flash memory is installed and
operating correctly. First, check that the router has recognised the flash
memory, using the command:
show system
display shows the types and sizes of memory installed in the router. If the flash
memory size is lower than expected, then the router’s boot process has not
correctly detected or recognised the flash memory’s presence. If recognition
fails, contact your authorised Allied Telesis distributor or reseller.
If the flash is recognised, enter the command:
show flash physical
to display flash memory size, device type and location.

If flash memory has been used in the past then it may already be formatted and
contain files. With erased or new flash memory that has been correctly
formatted, an 80 byte hidden system file is present. A typical display for an FFS

CompactFlash (AR725, AR745 only)
AR725 and AR745 routers have a CompactFlash slot on their front panel.
Compact flash cards increase the flash memory available for file storage.
CompactFlash files can be manipulated using the command line interface. Any
type of data, including versions, patches, GUIs and configurations can be
stored on compact flash cards. However, version, patch, and GUI files cannot
be run directly from CompactFlash. These files must be loaded into either NVS
or onboard Flash.
Caution Data contained on compact flash cards can be read with any
compliant reader. Do not keep sensitive data, for example security
keys, on compact flash cards.
!
The AT-CF128A 128 MB CompactFlash card has been approved for use with
the AR725 and AR745 routers. For the latest approved compact flash cards, see
CompactFlash cards. Using other cards may result in data loss.
Installing and removing a compact flash card
Compact flash cards can be inserted into the CompactFlash slot at any time.
CLI messages are displayed when a card is inserted or removed. It takes
approximately two seconds for an inserted card to be initialised. Messages
notify the user when a card has been inserted:
Info (1106257): Compact flash card inserted.
and when the card is ready for use:
Info (1106268): Compact flash card initialisation successful.
A message notifies the user if the compact flash card is not compatible with the
router:
Info (3106300): Compact flash card initialisation
unsuccessful.
When CompactFlash is in use, the CompactFlash Activity LED on the front
panel of the router is green.
Caution Do not remove the compact flash card when it is being
written to (that is, when the CompactFlash Activity LED is lit). Doing
so will corrupt data on the file being written.
!

processor, which operates independently of the base system. This processor is
responsible for the transfer of data between the base system and the PAC, and
the control of local high speed encryption and compression data processing
devices.
This architecture allows data encoding to be performed off-line without
involving the base router processor, thereby maximising PAC performance
while at the same time minimising impact on the router.

Local 32-bit processor for high speed control and data transfer.
Dedicated high performance 32-bit compression hardware.
High compression ratio Lempel-Ziv algorithm in hardware.
2 MBytes of history memory.
Support for up to 127 compression channels.
Compression and decompression operations are performed by a 32-bit data
compression coprocessor specifically designed for high-performance Lempel-
Ziv compression applications. The 2 MBytes of history memory allows up to
127 individual data links to use compression concurrently, enabling PACs to
typical compression ratios achieved by a PAC for a representative set of file
types.

Local 32-bit processor for high speed control and data transfer.
Dedicated high performance 32-bit Data Encryption Standard – DES and
Triple DES (3DES) – hardware.
PAC DES and triple DES encryption are based on a fast 32-bit device that
complies with FIPS PUB 46, ISO DEA-1 and ANSI X3.92 standards.
Dual Mode Throughput of an encrypted link can be dramatically increased by using data
compression. To support this, ECPACs support both encryption and
compression, providing a dual mode that allows combined compression and
encryption operations. So that the compression phase will have the best

opportunity at finding non-random data, compression occurs before
encryption, in the order:
compression → encryption →//→ decryption → decompression
Adding compression to an encrypted link increases line throughput. Once
compression has been carried out there is less data requiring encryption,
passing back to the base system, and transferring across the network, so less
base system bus and network link bandwidth is required for a given amount of
data. This results in the dual operation being very effective where encryption is
required.

Asynchronous Interfaces
Asynchronous interfaces, also known as terminal ports, (labelled ASYN0,
ASYN1, RS-232 or CONSOLE) use RJ-45 connectors, wired as DTE with one of
two pinout wiring schemes:

Asynchronous interfaces follow the RS-232 standard. A range of speeds is
selectable using the set asyn command from the Interfaces chapter of the
Software Reference.
Not all signals need to be connected. In particular, DCD, DTR, CTS and RTS are
not required unless the interface has been specifically set up to use them. See
the Terminal Server chapter in the Software Reference for more details. A typical
terminal connection will only require RXD, TXD and GND, but refer to the
equipment manual for the connected device for more specific data.
LPD print ports If LPD-based printer ports are required, then the router may
expect to ‘see’ the DTR signal from the printer connected to the DCD pin of the
router. This is used to detect both the fact that the printer is ‘online’ and that it

printer and lost. See the Printer Server chapter of the Software Reference.
Cables and Loopback Plugs
This section describes how to make cables for connecting the AR router to
networks, terminals, and printers. It also describes loopback plugs, which are
required for testing most router interfaces.

An alternative method, for both terminal and modem cables, is to wire an RJ-45
patch cord (a straight pin-to-pin cable with RJ-45 connectors on both ends) and
then use an RJ-45-to-DB25 adaptor wired internally as a crossed cable. These
adaptors are available in DB9 and DB25 female and male versions from data
cabling suppliers, and are supplied with wires terminated on the RJ-45 socket
and pins on the free ends. The pins are inserted into the appropriate positions
in the DB9 or DB25 shell.

Loopback Plugs for Testing Interfaces
Loopback plugs are used in conjunction with the Test Facility software (see the
Test Facility chapter) to test the router’s physical interfaces. 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.
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, most tests performed by the Test Facility require a
loopback plug to be inserted in the interface being tested.

Some interfaces (e.g., the synchronous ports) require a specially built external
testing device (available from your authorised Allied Telesis distributor or

Test Facility
A Test Facility designed to test the router’s physical interfaces is built into all
the router software. The Test Facility can be thought of as a specialised
interface module like PPP or Frame Relay. Although the router can continue to
operate normally during specific tests, any interfaces being tested are
dedicated to the Test Facility. For more information on the Test Facility’s
operation, see the Test Facility chapter of the Software Reference.
The routers support a wide range of interface types, including Ethernet,
asynchronous, synchronous, Basic Rate ISDN and Primary Rate ISDN.
interface types (except Ethernet interfaces on the AT-AR026 PIC) can be tested
independently using the Test Facility software. Most tests, however, will also
require the use of a loopback plug. For more information on loopback plugs,
AR026 PIC The Test Facility does not test Ethernet interfaces on AT-AR026
PICs.
The following examples show how to test specific interfaces.

command:
Interface Tests
enable test int=portn
where n is the interface number. This will run the test for 4 minutes. Use the
show test command (from the Test Facility chapter of the Software Reference),
to observe the test progress.
Ethernet Interface A loopback plug is required to run the first part of the Ethernet test on eth ports
how to make a loopback plug.
Tests for Switch and

where n is the Ethernet interface number.
To start a test of a switch port interface, use the command:
enable test int=portn
where n is the switch port number.
This will run the test for 4 minutes. Use the show test command (from the Test
Facility chapter of the Software Reference), to observe the test progress.
AR770S To test an eth port on the AR770S in 1000 Mbps mode, loop the port
back to the other eth port. To test a switch port in 1000 Mbps mode, loop the
port back to another switch port. In 10 Mbps or 100 Mbps mode, either loop the
port back to another port, or use a loopback plug. If two or more ports are
looped back to each other, you must test both ports at the same time. Use the
command:
enable test int=base
AR026 PIC The Test Facility does not test Ethernet interfaces on AT-AR026
PICs.
WAN Port Tests To fully test synchronous interfaces, an external tester (available from your
authorised Allied Telesis distributor or reseller) is required. A loopback plug is
not required to test BRI interfaces.
To start a WAN interface test, use the command:
enable test int=synn
or
enable test int=brin
where n is the WAN interface number. This will run the test for 4 minutes. Use
the show test command (from the Test Facility chapter of the Software

Restricted Maintenance Procedures
This section contains procedures that should only be performed by authorised
service personnel. Unauthorised use of procedures in this section may cause
danger of injury from electric shock, damage to the router, and invalidation of
the product warranty.
If you would like to know more about the procedures outlined in this section,
please contact your authorised Allied Telesis distributor or reseller.
Diagnostics
The router software includes a set of diagnostic programs. These programs
perform basic level checks of all system components. They do not run in
conjunction with the normal operating code, and require that the system be
totally dedicated to their use. A detailed knowledge of the way your router
hardware functions is necessary if diagnostics are to be used effectively.
Caution Diagnostic mode is only to be used by authorised service
personnel. Unauthorised use of diagnostic mode may cause the router
to cease functioning.
The router will not function as a router if diagnostic mode is running.
!
AR026 PIC The diagnostics programs do not perform checks on AT-AR026
PICs.
To enable diagnostics mode:
1. Connect a terminal to the console port.
Connect a terminal to the console port (port 0) on the router’s rear panel,
and set the terminal communications parameters to:
•
•
•
•
•
9600 bps
8 data bits
1 stop bit
No parity
Hardware flow control
2. Restart the router.
Restart the router, either by switching it off and on again using the power
switch on the rear panel, or by using the terminal to login and enter the
command:

Lithium Battery Replacement
The routers have a replaceable lithium battery. The battery should be replaced
when the router:
•
•
•
•
•
has been in storage for more than two years
has only been powered up intermittently over a two year period
loses its time setting
displays the message “ERROR: BBR Battery low”
loses its configuration during a power cycle
Caution Batteries should be replaced by authorised service personnel
only. Unauthorised opening of the router lid may cause danger of
injury from electric shock, damage to the router, and invalidation of
the product warranty.
!
The battery must be replaced by a 3 V lithium button cell, type CR2032
or equivalent.
