Page 24

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

You should inspect all items for shipping damage. If you detect any damage, do not install the ARN. Call the Bay 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.

1-2

Refer to the fo llowing 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 connect ing 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, ei ght #6 Phi ll i ps sc rews, four #10 cagenut screws and

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

___Four rubber feet for table-top operation.

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 re sults o f star tup diag nosti cs and p erform manual b oot conf igu ratio ns. Or you can attach any AT-compatible modem to allow remote dial-in access to diagnostics and configuration.

Note:

T o use the Netboot, Directed Netboot, or Local Boot option s for booting 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-D Rev 00

Page 27

Verifying Site Requirements

The installation site must provide a certain amount of free space around the ARN to dissipate heat, as de tailed in Table 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 electri cal and environmental specifications listed in Appendix C.

Installing the ARN

Caution:

You must use grounded electrical power outlets with the ARN.

Installing the ARN

Once 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 AR N) 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-D Rev 00

1-5

Page 28

Installing and Operating BayStack 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 no t hav e threade d 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:

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.

Attach a flange bracket to each side of the ARN.

Align four bracket holes with four holes in the ARN enclosure

(Figure 1-2)

The Ethernet base and expansion modules can also contain an optional data collection module (DCM). This optional DCM gathers Ethernet statistics for a remote monitoring (RMON) utility. A subset of these statistics is gathered with a built-in RM ON function on the Ethernet10/100BASE-Tx and -Fx interfaces. See Configuring RMON and RMON2 on BayRS Routers for information about h ow to enable and use each RMON data collection implementation.

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 netw or k admi nis tr at or 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 1-14

• “Connecting to a Serial Interface ” on page 1-16

• “Connecting to the ISDN Interface” on page 1-18

• “Connecting to the 56/64K DSU/CSU Interface” on page 1-19

• “Connecting to the E1/FE1 DSU/ CSU Interface” on page 1-21

• “Connecting to the X.25 PAD Interface” on page 1-24

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) transceiv er interf ace or a UTP inter face -- you can onl y use one interface at a ti me . F or example, you can connect to either t he 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-D Rev 00

Page 33

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:

Connect an Ethernet AUI drop cable to the interface labeled AUI (Figure 1-5

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

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.

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

When you start the ARN for the fi rst time, it complet es an initial sta rtup proced ure 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 compl ete the initial sof tware startup. Table 2-1 summarizes the four optio ns; the sect ions that fol lo w prov ide steps f or completi ng each option.

Starting the ARN for the First Time

The ARN factory def aul ts ar e set to find the image file a nd 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 (C OM) interfaces u sing 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 BayStack 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 wit h t he 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 follow ing sections describe how to use each of the different boot options for

the ARN.

114200-D Rev 00

Page 61

Using EZ-Install

EZ-Install is the default installation option provided by Bay Networks. This option requires th at your netw ork a dminist rator has set up th e netw or k so that you can start the EZ-Install procedure. In addition, this option requires that you:

• Install a flash memory c ard.

For instructions, see “Installing the Flash Memory Card” on page 1-33.

• Conn ect at least one serial (C OM) interfac e 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 E Z-Install:

Starting the ARN

114200-D Rev 00

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.

Ensure that the ARN boots correctly.

When the ARN boots, its LEDs fl ash 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.

Page 62

Installing and Operating BayStack ARN Routers

Using Netboot, Directed Netboot, or Local Boot

When you netboot or local boot t he 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 c ard. 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 1-25).

To interrupt the boot process:

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-D Rev 00

Page 63

While the router is running the EZ-Install procedure, issue a break 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 type. Some management consoles have specific “Break” keys on their keyboards; other require a key sequence to issue a bre ak (for ex ample,

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 pr ogrammable r ead-only memory (PROM) code for the module you are installing. BayRS r elease media incl udes t he l atest boot and d iagnost ic c ode 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 ve rsi on of boot and diagnostic code yo u n eed 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:

Turn off the ARN.

Set the power switch to 0, off (refer to Figure 1-25 in Chapter 1).

Warning:

Caution:

You cannot hot-swap ARN WAN adapter modules.

If present, turn off or disconnect the redundant power supply. Attach an antistatic wrist strap.

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.

Turn power on, and check the diagnostic LEDs on the front panel of the base module.

See “Ensuring a Successful Installation” in Chapter 3.

Note:

See your module-specific Supplement for information about the LEDs on the newly installed module. The new module’s LEDs will not indicate data transfer until you have configured and enabled software services.

If the module fails its diagnost ic test, t he Fai l LED remains on a nd the module LED flashes rapidly.

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 ta sks 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 softw are for additi onal inter faces may incr ease th e 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

ifconfig

to do the following:

• Configure the router’s initial IP interface to the ne twork. (The ini tial IP

interface shou ld be a ser ial in te rf ace if yo u are usi ng EZ-In stal l.) You also use the same procedure to configure other seri al interfaces fo r the netbooting procedure.

• Configure Ethernet or token ring interfaces for the netbooting procedure.

• Enable or disable netbooting on an interface.

Configuring an IP Serial or 56/64K DSU/CSU Interface for Netbooting

Configure a serial or 56/64K DSU/CSU (COM) interface to the IP network using the following interface configuration command:
