Canada Requirements Only

Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines
and internal metallic water pipe system, if present, are connected together. This precaution may be particularly
important in rural areas.

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric
inspection authority, or electrician, as appropriate.

Notice: For equipment using loopstart lines, please note that the Ringer Equivalence Number (REN) assigned to each
terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone
interface. The termination on an interface may consist of any combination of devices subject only to the requirement
that the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5. The REN is located on the “FCC
Rules Part 68” label located on the bracket of the module, or on the back of the unit.

Canada CS-03 -- Règles et règlements

Av i s : L'étiquette d'Industrie Canada identifie le matériel homologué. Cette étiquette certifie que le matériel est
conforme aux normes de protection, d'exploitation et de sécurité des réseaux de télécommunications, comme le
prescrivent les documents concernant les exigences techniques relatives au matériel terminal. Le Ministère n'assure
toutefois pas que le matériel fonctionnera à la satisfaction de l'utilisateur.

Avant d'installer ce matériel, l'utilisateur doit s'assurer qu'il est permis de le raccorder aux installations de l'entreprise
locale de télécommunication. Le matériel doit également être installé en suivant une méthode acceptée de
raccordement. L'abonné ne doit pas oublier qu'il est possible que la conformité aux conditions énoncées ci-dessus
n'empêche pas la dégradation du service dans certaines situations.

Les réparations de matériel homologué doivent être coordonnées par un représentant désigné par le fournisseur.
L'entreprise de télécommunications peut demander à l'utilisateur de débrancher un appareil à la suite de réparations ou
de modifications effectuées par l'utilisateur ou à cause de mauvais fonctionnement.

Pour sa propre protection, l'utilisateur doit s'assurer que tous les fils de mise à la terre de la source d'énergie électrique,
des lignes téléphoniques et des canalisations d'eau métalliques, s'il y en a, sont raccordés ensemble. Cette précaution
est particulièrement importante dans les régions rurales.

Avertissement: L'utilisateur ne doit pas tenter de faire ces raccordements lui-même; il doit avoir recours à un service
d'inspection des installations électriques, ou à un électricien, selon le cas.

Av i s : Veuillez prendre note que pour tout appareillage supportant des lignes de type “loopstart,” l'indice d'équivalence
de la sonnerie (IES) assigné à chaque dispositif terminal indique le nombre maximal de terminaux qui peuvent être
raccordés à une interface. La terminaison d'une interface téléphonique peut consister en une combinaison de quelques
dispositifs, à la seule condition que la somme d'indices d'équivalence de la sonnerie de tous les dispositifs n'excède pas

that follow:

• Your shipment is complete and undamaged.

• You have the proper equipment and tools.

114200-E Rev 00

1-1

Installing and Operating Passport ARN Routers

• Your installation site meets physical, electrical, and environmental

requirements.

• You have the communications devices and the cabling that you need to attach

to the ARN.

Verifying Shipment Contents

You should inspect all items for shipping damage. If you detect any damage, do
not install the ARN. Call the Nortel Networks Technical Solutions Center in your
area, as described in “How to Get Help.”

In addition to the ARN and this guide, your shipping container should contain
several other hardware accessory items. Verify that the items in the shipping
container match those on the packing list affixed to the shipping container.

Refer to the following checklist when verifying the contents of the shipping
container:

__ One power cable for connecting the ARN to a wall outlet.

__ One console/modem cable kit (Order No. 110310) for connecting an optional

local console or modem. The console/modem cable kit contains one 15-foot
AT standard molded serial cable (with DB-9 receptacle to DB-25 plug
connectors) and one null modem crossover adapter (with DB-25 to DB-25
receptacle connectors).

1-2

__ Two flange brackets, eight #6 Phillips screws, four #10 cagenut screws and

washers, and four cage nuts for rack-mounting the ARN.

___Four rubber feet for table-top operation.

Installing and Operating Passport ARN Routers

Additional Equipment

To install the ARN, you may need some additional items that are not part of the
ARN accessory package. Before installing the ARN hardware, ensure that you
obtain all the cables, tools, and other equipment that you need.

Cables

Unless they were specifically ordered, the cables necessary for your network
configuration are not part of the ARN accessory package. If you do not have the
proper cables, contact your network administrator or see the Cable Guide.

Management Console

You can attach an optional computer terminal or PC as a console to the ARN to
monitor the results of startup diagnostics and perform manual boot configurations.
Or you can attach any AT-compatible modem to allow remote dial-in access to
diagnostics and configuration.

To use the Netboot, Directed Netboot, or Local Boot options for booting

Note:

and configuring the ARN (see Chapter 3, “Operating the ARN”), you must
have a local terminal connected the first time the ARN powers up.

1-4

Mounting Hardware

To rack-mount the ARN, you need a Phillips screwdriver and an electronic
enclosure rack that meets the following specifications:

• Heavy-duty steel construction

• Electronic Industries Association (EIA) standard hole-spacing

• Width of 19 in. (48.26 cm) and depth of 24 in. (60.96 cm)

If the rack does not have threaded rail holes, you must use cage nuts (see

Figure 1-1

) to use with the cagenut screws.

114200-E Rev 00

Verifying Site Requirements

The installation site must provide a certain amount of free space around the ARN
to dissipate heat, as detailed in Ta bl e 1 -1

Table 1-1. Installation Space Requirements

Width Depth (minimum) Depth (for servicing)

22.5 in. (57.2 cm) 15 in. (38.1 cm) 25 in. (63.5 cm)

In addition, the installation site must meet the electrical and environmental
specifications listed in Appendix C.

Installing the ARN

.

Caution:

You must use grounded electrical power outlets with the ARN.

Installing the ARN

When you are ready to install the ARN in its final location, you have two options:

• Position the ARN on a flat, sturdy, horizontal surface.

• Mount the ARN in an electronic enclosure rack.

Positioning the ARN on a Flat Surface

When positioning the ARN on a flat surface, make sure that the surface is:

• Large enough for the ARN to operate properly (Table 1-1)

• Sturdy enough to support the combined weight of the ARN and any cables

that you connect

You should place the self-adhesive, rubber feet (shipped with the ARN) on the
bottom of the ARN chassis. These feet not only protect the surface on which you
position the ARN, they provide added friction against the weight of any cables
that you attach to the device.

114200-E Rev 00

1-5

Installing and Operating Passport ARN Routers

Rack-Mounting the ARN

For this procedure, you need:

• Two flange brackets and eight #6 Phillips screws (shipped with the ARN)

• A Phillips screwdriver

• An electronic enclosure rack. If the rack does not have threaded rail holes, you

must attach the four cage nuts shipped with the ARN.

• Four #10 cagenut screws and washers (shipped with the ARN)

To rack-mount the ARN:

1. Determine how you want the ARN to fit in the equipment rack.

Multiple holes in the flange brackets provide several options for
rack-mounting the ARN. How you attach the flange brackets determines how
far the router extends outside or remains inside the rack. Figure 1-2
three of the most common locations for the brackets.

2. Attach a flange bracket to each side of the ARN.

remote monitoring (RMON) utility. A subset of these statistics is gathered with a
built-in RMON function on the Ethernet10/100BASE-Tx and -Fx interfaces. See
Configuring RMON and RMON2 on BayRS Routers for information about how to
enable and use each RMON data collection implementation.

Installing and Operating Passport ARN Routers

Connecting Communications Cables

Gather the communications equipment and cabling that you will attach to the
ARN. If you do not have the proper cables, contact your network administrator or
see the Cable Guide.

Note:

For cable interface descriptions, see Appendix C.

Then, complete the steps in the applicable sections:

•“Connecting to an Ethernet Interface” on page 1-10

•“Connecting to a Token Ring Interface” on page 1-13

•“Connecting to a Serial Interface” on page 1-15

•“Connecting to the ISDN Interface” on page 1-17

•“Connecting to the 56/64K DSU/CSU Interface” on page 1-18

•“Connecting to the FT1/T1 DSU/CSU Interface” on page 1-18

•“Connecting to the E1/FE1 DSU/CSU Interface” on page 1-19

•“Connecting to the X.25 PAD Interface” on page 1-21

Connecting to an Ethernet Interface

You can connect an Ethernet cable to any ARN base or expansion module that
contains an Ethernet interface option.

Note:

On Ethernet modules that offer two interface types -- an attachment unit
interface (AUI) transceiver interface or a UTP interface -- you can only use one
interface at a time. For example, you can connect to either the AUI transceiver
interface or the 10BASE-T UTP interface on the base module, but you cannot
use both interfaces at the same time.

1-10

114200-E Rev 00

Installing the ARN

Connecting to the AUI

The AUI interface provides broadband, baseband, fiber, and shielded twisted pair
(STP) support, depending on the transceiver and cables you use.

Caution:

Connecting the ARN AUI interface directly to the AUI interface on
an Ethernet station violates IEEE 802.3 standards. The AUI interface is
designed only for connection to a transceiver.

To attach an Ethernet AUI transceiver (drop) cable to the AUI connector on an
Ethernet module:

1. Connect an Ethernet AUI drop cable to the interface labeled AUI

(Figure 1-5

).

The cable must have a 15-position D-SUB receptacle.

Connecting to a Token Ring Interface

You can connect a token ring cable to any ARN base module or expansion module
that contains a token ring interface option. Each of these interface options offers
two token ring interface types: an STP interface or a UTP interface.

Note:

You can use only one token ring interface on an ARN base or expansion
module at any time. For example, you can connect to either the STP interface
or the UTP interface on a base module, but you cannot use both interfaces at
the same time.

Using Netboot, Directed Netboot, or Local Boot 2-6

Where to go next 2-15

Understanding the Startup Process

To operate, the ARN requires two files: a software image and a configuration file.
Each time you start the ARN, it completes a process to load these files.

• The software image contains a group of executable files that support the

protocols that the network requires. The ARN uses the software image called
arn.exe. The process of obtaining and using this image is called booting.

• To bridge and route traffic, the ARN also needs a configuration file that is

tailored to the network. A configuration file is a binary system file that
contains hardware and software configuration data. The default configuration
file is named config.

Nortel Networks ships the executable and default configuration files on a
PCMCIA flash card, but the ARN can also obtain them over the network. Getting
a file over the network is called network booting, or netbooting. Getting a file
from the router file system, stored in flash memory, is local booting.

114200-E Rev 00

2-1

Installing and Operating Passport ARN Routers

When you start the ARN for the first time, it completes an initial startup procedure
to boot and connect to the network using either a default configuration file or one
already customized and available on the network.

You use one of four boot options to complete the initial software startup. Tab le 2 -1
summarizes the four options; the sections that follow provide steps for completing
each option.

You may not be able to use all methods described in this chapter to boot over some
interfaces on your router. For example, you cannot netboot over an FT1/T1
interface. In some cases, you may use one interface to boot your router and then
switch to a different interface (such as the FT1/T1 DSU/CSU) to establish your
initial IP network connection to the management workstation.

Installing and Operating Passport ARN Routers

Starting the ARN for the First Time

The ARN factory defaults are set to find the image file and configuration file from
the following locations:

• Image file -- on the local PCMCIA flash memory card

• Configuration file -- over the network

These default settings work with the default EZ-Install procedure.

The first time you power on an ARN, the router steps through its diagnostic tests
and then attempts to boot over all of its serial (COM) interfaces using EZ-Install.

Note:

Coordinate the initial startup of the ARN with your network
administrator. To determine which software configuration option is best for
your site and for instructions on setting up a boot server, the network
administrator can refer to Configuring Passport Remote Access.

If your network administrator has configured the network for the EZ-Install
procedure, the router boots using its local image and obtains its configuration file
over the network. Your network administrator can then connect to the ARN and
manage it remotely. For more information, refer to the next section, “

EZ-Install.”

Using

2-4

If your network administrator does not configure the network for EZ-Install, the
ARN cannot obtain its configuration file from the network, and the EZ-Install
procedure fails. The ARN then attempts to boot locally with the configuration file
that resides on its flash memory card. Refer to “

Using Netboot, Directed Netboot,

or Local Boot” for more information.

If both the EZ-Install and local boot attempts fail, the EZ-Install and local boot
processes repeat until one of the following occurs:

• The ARN boots successfully.

• You interrupt the boot process to enter the ARN monitor.

• You turn off the ARN.

The following sections describe how to use each of the different boot options for
the ARN.

114200-E Rev 00

Using EZ-Install

EZ-Install is the default installation option provided by Nortel Networks. This
option requires that your network administrator has set up the network so that you
can start the EZ-Install procedure. In addition, this option requires that you:

• Install a flash memory card.

For instructions, see “Installing the Flash Memory Card” on page 1-31.

• Connect at least one serial (COM) interface to the network.

For instructions, see “Connecting Communications Cables” on page 1-10.

Note:

If your ARN does not have a COM interface, you must configure the
ARN using one of the other methods such as netboot or directed netboot over
an Ethernet or token ring interface. Or, you may local boot the ARN and run
the Quick-Start script. For more information, see “Using Netboot, Directed
Netboot, or Local Boot” on page 2-6

To use EZ-Install:

Starting the ARN

.

114200-E Rev 00

1. Press the power switch on the ARN back panel to the ON position.

The ARN comes on and activates EZ-Install.

Note:

If you power on the ARN before the network administrator is ready,
restart the ARN by pressing the reset button on the rear panel. See Chapter 3,
“Operating the ARN” for more information on resetting the ARN.

2. Ensure that the ARN boots correctly.

When the ARN boots, its LEDs flash in a particular order. For information on
checking the ARN front-panel LEDs to ensure that the installation was
successful, see “Understanding the ARN LEDs” on page 3-1.

2-5

Installing and Operating Passport ARN Routers

Using Netboot, Directed Netboot, or Local Boot

When you netboot or local boot the ARN, you must use a command line interface
that accesses the router software. To use a command line interface, you can:

• Wait for the ARN to local boot (that is, wait for the router to fail EZ-Install

and then attempt to boot using its local configuration file). After the ARN
boots locally, you can log in to the Technician Interface and redefine the boot
process.

• Interrupt the boot process using a break sequence and log in to the ARN

monitor to redefine the boot process.

Using the netboot, directed netboot, or local boot options requires that you:

• Connect any necessary communications cables to access the network.

• Connect a management console.

• Connect the ARN power cable.

• Install a flash memory card.

See Chapter 1, “Installing the ARN” for instructions on how to complete these
tasks.

Interrupting the Boot Process

Interrupting the boot process automatically starts the ARN monitor. Using the
ARN monitor allows you to bypass the EZ-Install procedure.

Note:

Before you power on the ARN, make sure that you have installed the
router and connected the management console equipment you need (see
“Connecting a Management Console” on page 1-23).

To interrupt the boot process:

1. Press the power switch on the ARN back panel to the On position.

As the router powers on, your console displays the ARN diagnostic tests.
After successfully completing these tests, the router begins the EZ-Install
procedure and attempts to boot over the network.

2-6

114200-E Rev 00

2.

While the router is running the EZ-Install procedure, issue a break
sequence from the management console.

The ARN monitor login prompt appears.

Be sure to issue a break sequence before the boot process completes.

Note:

Break sequences can vary, depending on the console type. Some management
consoles have specific “Break” keys on their keyboards; other require a key
sequence to issue a break (for example,

Cntrl-C

for your management console, see the PC/terminal documentation.

Logging in to the Command Line Software

Regardless of the command line software used (ARN monitor or Technician
Interface) the procedures to log in are identical.

To log in to the command line:

1. Type the following command (noting the use of an uppercase “M”) at the

login prompt and press the Return key:

Protecting Memory Card Files

Nortel Networks ships each memory card with its read/write protect switch in the
unprotected position (Figure 3-5)
and saving your configuration, you may want to write-protect the memory card for
backup purposes.

Note:

You typically do not operate the ARN with a write-protected memory
card. You should make a copy of your configuration on another memory card,
write-protect that card, and store it in a safe place.

To change memory card protection, complete the following steps:

1. Remove the memory card as described on page 3-13.

2. Adjust the read-write protect switch, which is located on the edge

opposite the INSERT arrow of the memory card (Figure 3-5)

Note:

This chapter provides generic instructions that apply to all ARN WAN

this document refers to a module-specific Supplement, which ships in the
adapter module upgrade kit.

Preparing for Installation

Before installing the module, examine the contents of your adapter module
upgrade kit. If any parts appear damaged, call the Nortel Networks Technical
Solutions Center immediately.

Downloading New Boot and Diagnostic Code

When installating an adapter module as an upgrade to your existing hardware
configuration, you must verify that the ARN contains the minimum required
version of programmable read-only memory (PROM) code for the module you are
installing. BayRS release media includes the latest boot and diagnostic code at the
time it is shipped, but if your upgrade requires newer code, you must manually
download it to the router PROM.

To determine which version of boot and diagnostic code you need when installing
a particular adapter module, see see the module-specific Supplement that ships
with the module, and to the Document Change Notice or the Release Notes
distributed with your BayRS release. For instructions on how to upgrade the
PROM code in flash memory, refer to the Upgrading Routers guide.

Powering Down

Before installing a WAN adapter module:

1. Turn off the ARN.

Set the power switch to 0, off (refer to Figure 1-25 on page 1-30).

4-2

Warning:

2. If present, turn off or disconnect the redundant power supply.

3. Attach an antistatic wrist strap.

Caution:

You cannot hot-swap ARN WAN adapter modules.

Electrostatic discharge can damage hardware. You must wear the

antistatic wrist strap whenever you handle printed circuit boards.

You receive an antistatic wrist strap with the adapter module. See the
instructions included with the wrist strap.

The wrist strap directs static electricity from your body to the router chassis,
preventing discharge to sensitive electronic components.

What to Do Next

Before you can use the WAN adapter module after installation, you must start the
router on the network and modify its configuration file to include the new
interface.

See your module-specific Supplement for a list of software installation tasks and
related documentation.

Please note the following:

• BayRS recognizes the ARN WAN adapter module interfaces by their
front-panel slot number. For example, even if there is no adapter module
installed in slot 1, the interface in slot 2 is named COM2 or ISDN2.

• Configuring software for additional interfaces may increase the ARN memory
requirements.

Using the ifconfig Command

A router interface cannot communicate in an IP network without an IP address.
Because an ARN netboots over one of its serial, 56/64K DSU/CSU, Ethernet, or
token ring links, the netboot interface must have a valid IP address.

You use the interface configuration command

• Configure the router’s initial IP interface to the network. (The initial IP

interface should be a serial interface if you are using EZ-Install.) You also use
