Installing and Operating BayStack ARN Routers
Preparing to Install the ARN
Verify the following before beginning the installation, as explained in the sections
that follow:
•Your shipment is complete and undamaged.
•You have the proper equipment and tools.
•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
We strongly suggest that you inspect all items for shipping damage. If you detect
any damage, do not install the ARN. Call the Bay Networks Technical Response
Center in your area, as described in “About This Guide.”
In addition to the ARN and this manual, your shipping container should contain
several other hardware accessory items. Verify that the items in the shipping
container match those on the packing list.
Note: You can find 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 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).
__ Two flange brackets and eight #6 flathead screws.
__ Four #10 cagenut screws and washers for rack-mounting the ARN.
__ Four rubber feet (for table-top operation).

Supplying Equipment
You may need items that are not part of the ARN accessory package. Before
installing the ARN hardware, ensure that you have 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 for
Routers and BNX Platforms.
Service Console
You can attach an optional VT-100 console (or equiv alent) 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.
Note: To use the Netboot, Directed Netboot, or Local Boot configuration
options (see Chapter 3), you must have a local terminal connected the first time
the ARN powers up.
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 cagenuts (see
igure 1-1) to use with the cagenut screws.

able 1-1.
Once you are ready to install the ARN in its final location, you can
•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
•Sturdy enough to support the combined weight of the ARN and any cables
that you connect
We recommend that you place the self-adhesive, rubber feet on the bottom of the
ARN chassis (shipped with the ARN). 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.

Rack-Mounting the ARN
For this procedure, you need
•Four #10 cagenut screws and washers (shipped with the ARN)
•Two flange brackets and eight #6 flathead screws (shipped with the ARN)
•A Phillips screwdriver
•An electronic enclosure rack
Note: If the rack does not have threaded rail holes, you must supply and attach
four cagenuts.
To rack-mount the ARN:
1.Attach a flange bracket to both sides of the ARN.
On each side of the chassis:
a.Align the holes in the longer end of the flange bracket with the
mounting holes near the front panel of the ARN (F
igure 1-2).
b.Insert a #6 flathead screw through each hole and into the ARN.
c.Tighten the four screws with a Phillips screwdriver.

see the Cable Guide for Routers and BNX Platforms.
Note: Refer to Appendix C, later in this manual, for ARN cable interface
descriptions.
Connecting to an Ethernet Interface
You can connect an Ethernet cable to any ARN base or expansion module that
contains an Ethernet interface option. Each Ethernet interface option offers two
Ethernet interface types -- an AUI transceiver interface or a 10Base-T interface.
Note: You can use only one Ethernet interface on an ARN base or expansion
module at any time. For example, you can connect to either the AUI
transceiver interface or the 10Base-T interface on a base module, but you
cannot use both interfaces at the same time.

Chapter 2
Starting the ARN
The first time you start the ARN, you complete an important software
configuration process -- you provide the ARN with the files it needs to operate
over the network. This chapter discusses the need for these specific startup files,
what methods you can use to ensure that the router installs and uses the
appropriate files, and how to use each of these installation methods.
Note: Coordinate the initial startup of the ARN with your network
administrator. This person refers to Configuring Remote Access to determine
which software configuration option is best for your site and for instructions
on setting up a boot server.
Software Installation
Before it can operate, the ARN hardware must install two startup files -- a
software image and a configuration file.
The software image is a group of executable files that operate the protocols that
the network requires. The process of installing and using this image is called
booting. The software image that the ARN uses is called arn.exe.
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.
Bay Networks ships the executable and default configuration files on PCMCIA
Flash cards.
114200 Rev. A2-1
Page 62
Installing and Operating BayStack ARN Routers
You must complete an initial startup procedure to obtain the executable and
default configuration files and connect the ARN to the network. Getting a file o ver
the network is called network booting, or netbooting. Getting a file from the ARN
file system, stored in Flash memory, is called local booting.
Caution: The ARN must contain a Flash memory card if you plan to obtain
any startup files through the local boot procedure. If you attempt to local boot
the ARN without the Flash memory card inserted, the router does not operate.
Refer to “Installing the Flash Memory Card” in Chapter 1 for instructions.
Understanding the ARN Boot Options
You use one of four boot options to complete software installation: EZ-Install,
Netboot, Directed Netboot, or Local Boot. T
the sections that follow provide steps for completing each option.

Installing and Operating BayStack ARN Routers
Starting the ARN for the First Time
The ARN f actory defaults are set to find the configuration and image files from the
following locations:
•Configuration file -- over the network
•Image file -- on the local PCMCIA Flash memory card
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.
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. Refer to the next section, “Using EZ-Install,” for more
information.
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.
2-4114200 Rev. A
Page 65
Using EZ-Install
EZ-Install is the default installation option. 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.
•Connect at least one serial (COM) interface to the network.
Refer to Chapter 1 for instructions on how to perform any of these tasks.
Note: If your ARN does not have a COM interface, you must configure the
ARN using netboot or directed netboot over an Ethernet, token ring, or
DSU/CSU interface, or local boot the ARN and run the Quick-Start script. Go
to the next section, “Using Netboot, Directed Netboot, or Local Boot,” for
more information.
To use EZ-Install:
1.Press the power switch on the ARN back panel to the ON position.
Starting the ARN
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
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. See Chapter 3 for
information on checking the ARN front-panel LEDs to ensure that the
installation was successful and that the router is operating properly.

Installing and Operating BayStack ARN Routers
Using Netboot, Directed Netboot, or Local Boot
You must use a command line interface that accesses the router software when
you netboot or local boot the ARN. 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.
Refer to Chapter 1 for instructions on how to perform 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 necessary management console equipment (refer to
Chapter 1 for instructions).
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.

sequence from the management console.
The ARN monitor login prompt appears.
Note: Be sure to issue a break sequence before the boot process completes.
Break sequences can vary, depending on the console equipment type. Some
console terminals have specific break keys on their keyboards; other
management terminals require a specific key sequence to issue a break (for
example,
Cntrl-C or ~ #). Refer to your console terminal or terminal emulator
documentation for the break sequence specific to your console equipment.

Ensuring a Successful Installation
After connecting the ARN to the netw ork, you can ensure a successful installation
by checking the diagnostic LEDs on the front panel of the base module (refer to
igure 3-1).
F
When you power on the ARN, the following sequence of front panel LED activity
should occur:
•All base module LEDs light momentarily; this tests that the LEDs are
operational.
•The Run, Boot, and Fail LEDs count through a short, initial startup sequence.
•The Pwr (power) LED lights and remains on.
•The Run LED begins flashing and continues to flash until the ARN completes
all diagnostic tests.
•As the diagnostic procedure tests each module, the LED representing that
module flashes slowly. If the module passes its diagnostic test, the LED
remains on. If the module fails its diagnostic test, the Fail LED remains on
and the module LED flashes rapidly.
Operating the ARN
•After completing the diagnostic testing procedure, the boot process begins.
The Run and Boot LEDs indicate the boot status as shown in T

When you remove a formatted memory card, the NVFS automatically removes
access to the card. When you insert and format a card or insert an already
formatted card, the NVFS automatically provides access.

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. We recommend making a copy of your configuration on another memory
card, write-protecting the card, and storing it in a safe place.
To change memory card protection, complete the following steps:
1.Remove the memory card as described in the previous section.
2.Adjust the read-write protect switch, which is located on the edge

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

Configuring the ARN for Netboot and Directed Netboot
Using the bconfig Command
To use netboot, you use the bconfig command to specify that the ARN
configuration file or software image resides on the network. To use directed
netboot, you use the
the full pathname to the software image and configuration file. To use local boot,
you use the
bconfig command to specify that the configuration file and software
image both reside on the local file system (that is, the PCMCIA Flash card).
bconfig Command Format
To configure an interface for netboot, use the following format for the bconfig
command:
bconfig -d [image | config]
To configure an interface for directed netboot, use the following format:
bconfig command to specify the IP address of the server and
