The NETBuilder II system consists of a 4-Slot, 8-Slot, or 8-Slot Extended chassis with a main processor (DPE) module, and Enterprise OS software.

Your new bridge/router is either an EZBuilt preassembled NETBuilder II system or a NETBuilder II system that you have assembled from components.

If you have an EZBuilt NETBuilder II system, it was preassembled before delivery. This guide assumes that you have followed the instructions in the hardware installation guide to:

Install a local terminal, PC (with a terminal emulation application), or modem to the console port of the main processor module.

The DPE module has two built-in ﬂash memory drives. The upper drive is drive A, and the lower drive is drive B.

The Enterprise OS software is available from 3Com on a preinstalled 20 MB ﬂash memory card or on CD-ROM. 3Com recommends that you buy the preinstalled ﬂash memory card for ﬁrst time NETBuilder II installations.

See the software packages that are available for your NETBuilder II system. The procedur es in this guide apply to all software packages.

INSTALLING SOFTWARE AND BOOTING

Installing Software and Performing Initial Boot

A NETBUILDER II SYSTEM

This chapter contains the following procedures:

■ Installing and booting Enterprise OS software

■ Making a backup copy of the software ﬂash memory card

Enterprise OS software can be installed in the following ways:

■ From a ﬂash memory card with preinstalled software. 3Com recommends this

method. EZBuilt NETBuilder II systems have a factory-installed software ﬂash memory

card. To boot your EZBuilt system, see “Booting an EZBuilt NETBuilder II System.”

For component NETBuilder II systems to boot from a ﬂash memory card, they must have a ﬂash memory drive installed. For installation instructions, see the NETBuilder II Flash Memory Drive Installation Guide. After you have installed a ﬂash memory drive, see “Booting a Component NETBuilder II System” on page 10 for instructions on booting your system.

Booting from the Flash Memory Card

Prerequisites Before you boot your new NETBuilder II system, you need to complete all setup

To start the NETBuilder II system from a ﬂash memory card with preinstalled software, follow the procedures in this section.

and installation instructions in the hardware guide provided with the system and system components. You also need to connect a console to your system.

The EZBuilt NETBuilder II system comes with a factory-installed ﬂash memory card that contains the Enterprise OS software. To boot an EZBuilt NETBuilder II system, follow these steps:

1 Turn on the EZBuilt NETBuilder system.

The NETBuilder II system boots from the default boot source a:/primary/boot.29K (the ﬂash memory drive).

2 When the boot operation is complete, press the Return key on the console.

The Enterprise OS console prompt should appear on the screen. If the console is not operating properly (if you see incorrect characters, or no

characters), see the setup instructions in the hardware installation guide. You are ready to establish basic settings on your system. See Chapter 4 for more

information.

Making a Backup of the Flash Memory Card

To boot a component NETBuilder II system, follow these steps:

1 Insert a ﬂash memory card with preinstalled software in drive A on the DPE

module.

2 Turn on the NETBuilder II bridge/router.

The NETBuilder II system boots from the default boot source a:/primary/boot.29K (the ﬂash memory drive).

3 When the boot operation is complete, press the Return key on the console.

The Enterprise OS console prompt should appear on the screen. If the console is not operating properly (if you see incorrect characters, or no

characters), see the setup instructions in the hardware installation guide. You are ready to establish basic settings on your system. See Chapter 4 for more

information. If you want to change the primary boot source from the default or adjust system

conﬁguration parameters, see Chapter 4 and the description in the SysconF appendix in Reference for Enterprise OS Software.

As part of the installation procedure, 3Com recommends that you cr eate a backup of your Enterprise OS software on a blank ﬂash memory card. See the software release notes for a list of ﬂash memory cards that can be used with the DPE module.

Prerequisites Before you begin this procedure, complete the following tasks:

1 Boot your NETBuilder II system with software on a ﬂash memory card inserted into

drive A of the DPE module.

Keep the original Enterprise OS software ﬂash memory card in a safe place and protect it from accidental damage. The original is your backup in the rare event that the Enterprise OS software or the backup ﬂash memory card becomes corrupted. See ”Using the Backup Flash Card” on page 11 for instructions on installing the backup ﬂash memory card.

6 The Enterprise OS software boot ﬁles for a DPE module are factory shipped with

a:/primary/boot.29k as the default primary boot source. If you have installed the Enterprise OS software on drive A, and you want to keep the same boot ﬁle as the boot source, reboot your NETBuilder II bridge/router by entering:

ReBoot

7 If you want to conﬁgure your primary boot source to a drive and ﬁle other than

the default, see Chapter 3 for instructions on conﬁguring the boot source for the NETBuilder II bridge/router.

Using the Backup Flash Card

If the Enterprise OS software has been corrupted and you need to reboot, use your original Enterprise OS software ﬂash memory card to reset your system by following these steps:

1 Remove the corrupted ﬂash memory card from the DPE module. 2 Insert the original Enterprise OS software ﬂash memory card into drive A on the

DPE module.

Press Reset buttons to reboot

The system boots from the Enterprise OS software ﬂash memory card in drive A.

4 Make a copy of the ﬂash memory card in drive A by following the steps in the

previous procedure.

You will need to either obtain an additional ﬂash memory card or reformat the corrupted ﬂash memory card. If you choose to reformat a corrupted ﬂash memory card, inspect the card to make sure that it is not damaged. Always keep the original Enterprise OS software ﬂash memory card in a safe place and protect it from accidental damage.

CHANGING THE BOOT SOURCE

This chapter describes how to change the primary boot source on a bridge/router or tunnel switch.

The Enterprise OS software boot ﬁles for the main processor module are factory shipped with a:/primary/boot.29k as the default primary boot source for NETBuilder bridge/routers. If you have installed the Enterprise OS software ﬂash memory card into drive A, and you want to keep the default boot source, go to Chapter 4.

If you want to adjust system conﬁguration settings, see the SysconF appendix in

Reference for Enterprise OS Software for instructions. 3Com recommends that you initially use the ReBoot command to boot the

bridge/router or tunnel switch. If this command fails, use the BT command.

Using the Boot Command

The Boot Monitor utility Boot (BT) command allows you to reboot or to override the default boot path. The BT command is useful if the boot path has a typing error or if you have a malfunctioning drive. If you enter a new boot path, the Primary Boot Source parameter is updated to reﬂect the new path.

To reboot the NETBuilder II bridge/router (or tunnel switch) using the Boot Monitor utility Boot command, follow these steps:

1 Reset the system in one of two ways. Either press the two outer buttons on the LCD

control panel on the front of the NETBuilder chassis, or press the reset button on the main processor module.

For more information about the Boot Monitor utility, see the Firmware appendix in Reference for Enterprise OS Software.

2 To enter the Boot Monitor utility, enter r: 3 Enter a boot path using:

BT <drive>:/<path>/<filename>

If you do not enter the <drive> value, drive A is used. To boot from drive A, enter:

BT a:/primary/boot29.k

The system attempts to boot from the speciﬁed image ﬁle. If an error occurs, a message is sent to the console and you are returned to the boot monitor.

For more information about the Boot Monitor utility, see the Boot Monitor appendix in Reference for Enterprise OS Software.

Conﬁguring the Primary Boot Source

Prerequisites Before beginning this procedure, complete the following tasks:

Drive A is the default primary boot source. This procedure establishes drive B as the primary boot source.

This procedure is provided as an example showing how to use the command. For actual operations, 3Com recommends that you boot from drive A and assign drive B to capture dumps.

■ Install the system software and boot the NETBuilder II system according to the

instructions in Chapter 2.

■ Attach a terminal, a PC with a terminal emulation program, or a modem for
