Choosing a PIC Bay
Observe the following guidelines when selecting a PIC bay:
■Use the PIC bays on the switch or router base unit first, before installing PICs
into an AT-AR040 NSM.
■Fill the PIC bays in an AT-AR040 NSM starting at bay 0.
■You can install a maximum of two AT-AR020 PRI E1/T1 PICs into an AT-AR040
NSM, and maximum of four total in a switch or router.
■If two AT-AR020 PICs are installed in an AT-AR040 NSM, PIC one must be
installed in the lower row (bay 0 or 1) and the other PIC must be installed in the
upper row (bay 2 or 3).
■If an AT-AR020 PIC is installed in an AT-AR040 NSM, and operating in E1 mode,
you can not install an AT-AR021(S) or AT-AR021(U) PIC in the same row of the
NSM.
■You can install a maximum of four AT-AR027 PICs in an AR745 router fitted with
an AT-AR040 NSM.
■Avoid installing an AT-AR022 or AT-AR026 PIC in an AT-AR040 NSM.
Performance of these interfaces may be reduced and packet loss may occur.
For instructions on installing an AT-AR040 NSM into your switch or router, see the
Network Service Module Installation and Safety Guide supplied with the NSM. You can

Installation and Safety Guide 5
Installing a PIC
This section describes the procedure for installing a PIC. You should also follow this
procedure, in particular the safety procedures and warnings, when replacing or
removing a PIC.
Caution You cannot install PICs into an AT-AR040 NSM that has power applied to
it. This includes NSMs that have been deactivated using the hot swap button, but not
physically removed from the switch or router. To ensure that all power is removed
from the NSM bay, you must either physically remove it from the switch or router
using the hot swap method, or disconnect all power sources to the switch or router.
1. Read the safety information.
For safety information, see the Installation and Safety Guide shipped with your
switch or router. You can also download the complete documentation for your
switch or router from www.alliedtelesis.com/support/software/.
2. Gather the tools and equipment you will need.
A medium-sized flat-bladed screwdriver may be useful when loosening the PIC
thumbscrews. You should also have any cables required for connecting the PIC
to a wide area network or other network devices.
3. Remove power to the switch or router.
Warning Do not install a PIC into an NSM bay or PIC bay base unit without
first removing power from the switch or router. Be sure to disconnect both the
main power supply and any attached redundant power supply. Installing a PIC
with the switch or router powered ON can damage the PIC, NSM and base unit.
4. Remove all TNV connections to existing PICs.
Warning Remove any cables attached to the external WAN ports of the
AT-AR020, AT-AR021 and AT-AR027 PICs, as these supply TNV into the
switch or router. Dangerous voltages may be present on some parts of the
board, even if the switch or router is powered OFF.
5. Install the AT-AR040 NSM if required.
Use the installation instructions in the Network Service Module Installation and
Safety Guide to install an AT-AR040 NSM.
6. Remove the PIC bay faceplate, NSM PIC bay faceplate, or existing PIC.
Loosen the thumbscrews to remove the faceplate or PIC. Keep the faceplate
for future use. If you remove the PIC, replace the faceplate to prevent dust and
debris from entering the switch or router and to maintain proper airflow.

7. Unpack the PIC.
In an antistatic environment, remove the PIC from its packing material. Be sure
to observe ESD precautions.
Warning Do not attempt to install a PIC or any other expansion option
without observing correct antistatic procedures. Failure to do so may damage
the switch or router, PIC, or expansion option. If you are unsure what the
correct procedures are, contact your authorised Allied Telesis distributor or
reseller.
8. If the PIC has jumpers, check they are correctly set.
Warning Do not attempt to change any jumpers, DIP switches, or other
hardware configurations while the switch or router is connected to a power
supply, redundant power supply, or a ‘live’ network. Dangerous voltages may be
present on some parts of the board, even if the switch or router is turned off.
AT-AR020 PRI E1/T1 and AT-AR021(S) BRI-S/T PICs have user-configurable
jumpers. Check all jumpers are set correctly on the new PIC, as shown in
Ta b l e 1 and Ta b l e 2 . Early versions of the AT-AR020 PIC also have a J3 interface
jumper. If present, this jumper must be installed for E1 mode and removed for
T1 mode. The AT-AR021(S) V2 hardware revision, identified by the label
“AR021 V2” on the board, supports both TE and NT mode. Jumper J4, when
installed, selects NT mode. The PIC should be configured as a TE for normal
operation.
Table 1: Functions of jumpers on the AT-AR020 PRI E1/T1 PIC board
Jumper Function Default
J1 ISDN NT mode (installed, test only) or
TE mode (not installed).
Not installed.
J2 T1 mode (installed) or E1 mode (not installed). Installed.
J3 E1 mode (installed) or T1 mode (not installed).
Only present on earlier versions of the PIC.

Installation and Safety Guide 7
AT-AR026 4ETH PICs have user-configurable links that set features such as
auto-negotiation, buffer size, and MAC address aging. For a detailed description
of the links, see the Port Interface Card Hardware Reference.
For more information on PIC jumpers and hardware configurations, see the
Port Interface Card Hardware Reference. This document can be downloaded from
www.alliedtelesis.com/support/software/.
9. Slide the PIC into place.
PIC bays should be filled in numerical order, starting with the lowest available
bay (e.g., bay 0) followed by bays with progressively higher numbers.
Insert the PIC slowly, being sure to keep it straight. Press firmly until you feel
the connector engage. Do not force a misaligned PIC.
10. Secure the PIC by tightening its thumbscrews.
11. Apply power to the switch or router.
Re-attach the power cord, and reconnect any redundant power supply.
12. Te s t t h e P I C .
There are several ways to check the PIC is installed and functioning correctly.
The show system command displays general system information about PICs
and any other hardware installed, as well as memory, software version and
patches loaded on the switch or router.
If the PIC does not appear in the list of boards at the top of the show system
output, then your switch or router has not recognised the PIC. Likely reasons
are:
• Your switch or router does not support the PIC. See “Compatible Switches
and Routers” on page 3.
• Your switch or router is running a version of the AlliedWare®Operating
System that does not support the PIC. Use the show system command to
check the software version. In particular, the AT-AR021(S) V3 hardware
revision requires a switch or router running AlliedWare®Operating System
version 2.9.1-13 or later.
• The PIC is not installed correctly. Repeat the installation process, paying
particular attention to step 9.
For more detailed information on testing PICs, see the Port Interface Card
Hardware Reference. You can download this document from
www.alliedtelesis.com/support/software/.

Setting the ISDN Territory
Before you connect an AT-AR020 or AT-AR021 PIC to the ISDN network, check
that the ISDN territory is set correctly for your region.
1. Log in to your switch or router.
For more information, see the Installation and Safety Guide included with your
switch or router. You can also download the complete documentation for your
switch or router from www.alliedtelesis.com/support/software/.
2. Set the territory, using the command:
set system territory={australia|china|europe|japan|korea|
newzealand|usa}
In Australia only:
• To use the Micro service, set the territory to australia.
• To use the OnRamp service, set the territory to europe.
3. Save the configuration.
Save your configuration to a new file by using the command:
create config=filename.cfg
Then set the router to load this file when it restarts by using the command:
set config=filename.cfg
We recommend leaving the boot.cfg file unchanged, in case you need to revert
to the original default configuration.
See the AlliedWare®Operating System Software Reference for more information on
configuring ISDN.

Installation and Safety Guide 9
Downloading VoIP Firmware
If you have installed an AT-AR027 VoIP PIC, you now need to download and install
the VoIP firmware onto your PIC. Before you begin, check that the PIC Error LED
on the PIC is off, and that the PIC has been recognised by your switch or router,
using the show system command.
1. Download the VoIP PIC firmware.
Point your web browser at www.alliedtelesis.com/support/software/. Navigate
to the PIC product information page and find the firmware files you need from
the support page. You will need:
• the PIC boot code, which is responsible for loading the protocol image onto
the PIC
• the images for the protocols you wish to run on the PIC—SIP and/or H.323
Download the firmware files you need and save them to your TFTP server.
2. Load the boot code onto your switch or router.
To load the boot code from your TFTP server, use the command:
load method=tftp destination=flash server={hostname|ipadd}
file=filename
3. If possible, load the protocol image onto your switch or router.
If you have enough space, load the protocol image onto your switch or router’s
flash, so that it does not need to be continually connected to an external TFTP
server. Use the load command as described above.
4. Set the boot code and protocol image.
To set the boot code on the switch or router, use the command:
set voip bootcode=filename server={ipadd|flash}
This command sets the boot code filename, and specifies the location of the
protocol image that the boot code will load.
To set the name of the protocol image (file), and specify what type of VoIP
protocol the protocol image supports, use the command:
set voip file=filename protocol={h323|sip} type={fxs|fxo}
5. Set the interface for the VoIP traffic.
To set the preferred interface for VoIP traffic, use the command:
set voip public interface=interface
If a logical interface is not specified, 0 is assumed (that is, eth0 is equivalent to
eth0-0).
