Chapter 3

Starting the AN/D C and ANH-8/D C

The first time you start the AN/DC or ANH-8/DC, you complete an important software configuration process.

Before you begin the initial sta rtup from a remote site:

Coordinate with your network administrator. The network administrator, using the manual Connecting BayStack AN and

ANH Systems to a Network or Configuring Remote Access , determines which software configuration option is best for your site and configures the network to support it.

Install the PCMCIA Flash card supplied w ith the router. See “Installing the Flash Memory Card

For information about the software configuration methods, read the “About

Software Installa tion” section in this chapter.

To begin the startup process, follow the detailed instructions in one of these sections:

• Using EZ Install

• Using Netboot, Directed Netboot, or Local Boot

About Software Installation

To bridge and route traffic, the router needs a configuration file that is customized for the network and a software image mad e up of executable files -- an operating system kernel and applicat ion f iles. Nortel Net works s hips th ese f ile s on PCMCIA Flash media.

312410-A Rev 00

” in this chapter.

3-1

Installing and Operating AN/DC and ANH-8/DC Systems

You must complete an initial startup procedure to obtain the necessary files and connect the AN/DC or ANH-8/ DC to the network. Getting a file o ver the network is called network booti ng, or netbo oting. Getting a file from the router file system, stored in Flash memory, is called local booting.

Note:

This guide explains using Site Manager software to connect the router to a managed network. If you plan to use EZ Internetwork software to start the AN/DC or ANH-8/DC on the network, you use the Quick2Config software. Quick2Config is a Microsoft Windows-based appl ication that allows you to quickly and easily create or modify configuration files for Nortel Networks Access routers. See Configuring Y our Router Usin g the Quic k2Conf i g Tool for information.

Boot Options

You use one of four Site Manager boot options to complete software installation: EZ Install, Netboot, Directed Netboot, or Local Boot. Table 3-1 four options; the sections that follow provide steps for completing each option.

Installing the Flash Memory Card

A PCMCIA Flash memory card (Figure 3-1) provides storage capability for the nonv ol atile f ile syst em (NVF S) in the AN/ DC and ANH-8/ DC. When yo u remo v e a formatted memory card, the NVFS automatically re moves access to the card. When you insert and format a card or insert an already formatted card, the NVFS automatically provides access.

Although you do not need a modem or console connection for EZ Install, we strongly recommend that you connec t a modem or console. This let s you issue commands t o the router and view messages.

Contact your network administrator to verify that the remote network is set up so that you can start the EZ Install procedure.

Be sure that the Flash memory card is installed, as described earlier in this chapter.

Supply power as described in this chapter.

As the router powers on, it begins diagnostic tests. Your console displays the message

*****Testing Memory***** with the amount o f memory a vailable.

Once it passes diagnostic tests, the router automatically activates and completes EZ Install. (It gets a software image from the local file system, its IP address from the upstream router, and a configuration file from the BootP server.) The router then starts bridging and routing traffic.

When booting, the AN/DC and ANH-8/DC LEDs flash in a particular order. To interpret the LED sequence and trouble shoot any potential problems, refer to Chapter 4.
