PCI T echnology

The PCI local bus is a high-performance bus that provides a processor-independent data path between the CPU in a PC and high-speed peripherals. This interconnect mechanism is designed speciﬁcally to accommodate multiple high-performance peripheral devices that support networking and disk subsystems, graphics, full-motion video, and multimedia.

1-4 CHAPTER 1: INTRODUCTION

The PCI speciﬁcation deﬁnes two types of PCI devices: a target and a master. A target is a device that accepts commands and responds to the requests of a master. The master, or bus master, is a more intelligent device that can conduct processing independently of the bus or other devices. A bus master device shares the bus with the main processor and targets. Bus mastering allows a peripheral device to take control of the system bus and not rely on the central processor. The 3C971-F adapter is a bus master device.

The PCI speciﬁcation supports the following features:

■ High performance. The PCI local bus runs at a

clock speed of 33 MHz and employs a 32-bit data bus that supports multiple peripheral components and add-in cards at a peak bandwidth of 132 MBps, up to an order of magnitude greater than that of other PC buses (ISA, EISA, and MCA).

■ Automatic conﬁguration. A PCI adapter has

conﬁguration speciﬁcations set in on-board memory and provides installation information to the computer at start-up.

■ Shared slots. The PCI speciﬁcation calls for

“shared slots,” which denotes the shared expansion backplate slot. This shared backplate slot provides access to one of two types of adapters: a PCI adapter and an ISA adapter, for example, or a PCI adapter and an EISA adapter. Only one adapter at a time can be installed in a shared slot. Manufacturers are currently producing computers that support the PCI bus in conjunction with conventional ISA or EISA buses in the same chassis.

For detailed information about the PCI local bus, consult the PCI speciﬁcation.

HARDWARE INSTALLATION

Installation Overview

This section describes the procedure for installing the 3C971-F adapter hardware in your host computer. Follow all applicable instructions included with your system documentation for installing PCI bus adapters. Hardware installation consists of these basic steps:

■ Unpack the 3C971-F ATMLink PCI adapter.

■ Tur n off the power to your computer and remove the

computer cover. Refer to your system documentation for speciﬁc instructions.

■ Install the 3C971-F adapter in an available PCI slot.

■ Replace the computer cover.

■ Connect the appropriate cables.

■ Tur n on the power to the computer.

Please observe all special notes and precautions. For technical speciﬁcations on the 3C971-F adapter

hardware, see Appendix A.

Tools Required

The only tools required are a grounding strap and a #1 Phillips head screwdriver.

2-2 CHAPTER 2: HARDWARE INSTALLATION

Keep the 3C971-F ATMLink PCI adapter in the protective antistatic bag until you are ready to install it. To prevent adapter damage due to electrostatic discharge, wear a grounding strap and handle the adapter only by its edges. Do not touch the components or any metal parts on the adapter, except for the backplate.

Installing the 3C971-F Adapter

To install the 3C971-F adapter in your computer, perform the following steps:

1 Attach a grounding strap to your wrist or ankle

before handling the adapter.

2 Unpack and inspect the 3C971-F adapter for

damage.

3 Turn off the power to your computer and any

attached devices. WARNING:

Your computer operates with voltages that can be lethal. Before you remove the computer cover, carefully review the steps in this procedure and observe all cautions and warnings to protect yourself and to prevent damage to the computer.

4 Remove the cover from your computer.

Refer to the system documentation for your computer.

5 Locate an empty PCI bus expansion slot. 6 Remove the metal expansion slot cover from the

computer chassis, as shown in Figure 2-1.

Save the screw for step 9 later in this section.

10 Replace the system cover. 11 Connect the 3C971-F adapter to the network.

The connectors and cabling available for the 3C971-F adapter are SC duplex type connectors for multimode ﬁber, as shown in Figure 2-3.

12 Turn on the power to the computer.

When the computer power is turned on, the system BIOS should enable the PCI slot and initialize the 3C971-F adapter conﬁguration space.

The 3C971-F ATMLink PCI adapter is plug-and-play with systems that are compliant with the PCI Local Bus Revision 2.1 speciﬁcation. Computers that are not compliant may require manual conﬁguration using a PCI Device Conﬁguration menu in the BIOS. See your system documentation for PCI device conﬁguration.

The installation of the hardware for the 3C971-F ATMLink PCI adapter is complete.

The next step is to install the network software driver for the adapter card. Refer to Chapter 3 for Windows NT™ 3.51 workstations and servers, or to Chapter 4 for NetWare™ 4.1 servers.

Overview

WINDOWS NT DRIVER INSTALLATION

This chapter describes the procedure for installing a 3C971-F ATMLink PCI adapter dr iver for Microsoft Windows NT™ 3.51 workstations. The 3C971-F adapter driver provides standards-based ATM LAN emulation connectivity to an ATM network. This allows you to run legacy LAN applications, Ethernet networking technologies and Ethernet protocols over an ATM network.

The LAN emulation SVC driver utilizes signaling software to establish connections between two end stations on the ATM network. The driver operates below the host’s Link Level protocol. It provides for broadcast/multicast addressing, along with other LAN-like services, so that host network protocols function as if they were talking to a real MAC layer of an Ethernet interface. Connections are set up and torn down dynamically by the signaling software provided with the 3C971-F adapter. Once the LAN emulation server (LES) has been set up on the ATM network, it is easy to add a LAN emulation client (LEC) to the network.

CAUTION:

the UNI 3.0 standard for switched virtual circuits.

Multiple LAN Emulation Clients

The 3C971-F adapter can communicate with up to four LAN emulation servers (LESs) at a time. Dur ing installation of the hardware driver, four client

Your ATM switch must be set to support

addresses, Client 0 through Client 3, are assigned to the adapter. Each client has a MAC address, with Client 0 being assigned the true MAC address of the 3C971-F adapter. Clients 1 through 3 have a virtual MAC address, assigned by the driver, that is an increment of the true MAC address. Duplicate MAC addresses cannot occur on the network. The true MAC assignments at the factory are spaced in increments of 16 addresses. You are not required to use the three additional clients. Client 0, however, represents the true MAC addresses of the 3C971-F adapter and cannot be disabled.

Each client can be set to contact (at bootup time) a LAN emulation conﬁguration server (LECS) using the ATM Forum’s “well-known” LECS address. The LECS contains all the necessary conﬁguration information for each client to connect to the appropriate LAN emulation server. If an LECS is not in use or not available on the network, the user can set the client to contact an LES directly by entering the LES’s 20-byte ATM address.

Installation Procedures Overview

The basic installation procedures for these drivers are:

■ Verify the system requirements.

■ Install the adapter hardware driver.

■ Conﬁgure the PCI parameters.

■ Conﬁgure the signaling options.

■ Conﬁgure the TCP/IP interface.

■ Conﬁgure the LAN emulation clients (LECs).

System Requirements

The workstation must meet the following minimum requirements:

■ Intel x86 system running Microsoft Windows NT

version 3.51 or later

■ 24 MB of system memory (32 MB of system memory

is recommended for multiple VLAN ﬁle server applications)

■ 3.5 inch ﬂoppy disk drive

■ IP addresses for the enabled LAN emulation clients

■ Subnet mask for the network
