Choosing a PIC Bay
You can install a PIC into a PIC bay on your switch or router, or into an AR040
NSM. Use the available PIC bays on the switch or router base unit before installing
any PICs into an AR040 NSM. When using an NSM, fill the NSM PIC bays starting at
bay 0. For instructions on installing an AR040 NSM into your switch or router, read
the Network Service Module Installation and Safety Guide supplied with the NSM.
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.
You can install a maximum of two AT-AR020 PRI E1/T1 into an AR040 NSM. The
maximum number you can install in your switch or router is four.
Caution You cannot install an AT-AR020 into an AR750S-DP that is powered by
AC power supply units.
When using AT-AR027 PICs with an AR740 and AR745 router and NSM, you can
install a maximum of four AT-AR027 PICs in the router and NSM.

Installing a PIC
This section describes the procedure for installing a PIC. Follow the same
procedures, in particular the safety procedures and warnings, to replace or remove
a PIC.
1. Read the safety information.
For safety information, see the Installation and Safety Guide for your switch or
router. A copy of this guide can be found on the CD-ROM that came with your
switch or router, or at 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
AR020, AR021 and 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 AR040 NSM if required.
Use the installation instructions in the Network Service Module Installation and
Safety Guide to install an 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.

Installation and Safety Guide 5
613-000601 Rev A
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 not turned on.
AT-AR020 PRI E1/T1 and AT-AR021(S) BRI-S/T PICs have user-configurable
jumpers. Check all jumpers and other hardware configurations are set correctly
on the new PIC (see Table 1 and Table 2).
AT-AR026 4ETH PICs have user-configurable links that set features such as auto-
negotiation, buffer size, and MAC address aging. Descriptions of the links can be
found in the PIC Hardware Reference.
Earlier 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.
For more information on PIC jumpers and hardware configurations, see the Port
Interface Card Hardware Reference. This Reference can be found on the CD-ROM
bundled with recently purchased switches or routers, or can be downloaded
from www.alliedtelesis.co.uk/site/products/ .

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.
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. Test the PIC.
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.
See the Port Interface Card Hardware Reference for detailed information on PIC
testing.
Setting the ISDN Territory
You must change the default ISDN territory to your region before you connect an
ISDN PIC to your Telecommunications Network. Use 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.
See the Software Reference provided with your switch or router for further
information on configuring ISDN.

Downloading VoIP Firmware
The following instructions are for downloading the Voice over IP (VoIP) PIC
firmware onto your PIC. The instructions assume you have successfully installed the
VoIP PIC into your switch or router and made sure all the LEDs show as being on.
1. Download the VoIP PIC firmware
Open your web browser and enter the URL www.alliedtelesis.co.uk. Navigate to
the PIC’s product information page and find the firmware files you need from the
support page. You will need:
• the boot code for the PIC
This code is responsible for loading the protocol image onto the PIC
• the SIP protocol image and/or the H.323 protocol image
The protocol(s) you wish to run on PIC’s installed in your switch or router.
Download and save the firmware files you need 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 to the 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).

8 Port Interface Card
613-000601 Rev A
6. Load the protocol image onto the PIC or PICs.
To load the protocol image, use the command:
enable voip protocol={h323|sip} [engine={engine}]
The boot code loads the protocol onto all PICs unless you specify an individual
PIC (engine). The engine name is formed by concatenating a VoIP interface type
and an engine instance (for example, fxs2). A fully qualified engine name may also
be specified (for example, bay0.fxs0 or nsm0.bay1.fxs0).
Once the firmware is loaded, all the LEDs turn off. The figure below shows an
example of the screen output of the firmware download process.
