CHAPTER 1: INTRODUCTION

Congratulations on your purchase of the NETGEAR®GA622T Copper Gigabit Ethernet Card.Designed especially for high-performance systems, such as servers and high-end workstations,it offers 2 gigabits per second (Gbps) of aggregate bandwidth and optimized performance while minimizing network overhead on the host system. This guide describes the installation and use of the GA622T for operation within a

Microsoft Windows Me

This chapter provides information about the features of the GA622T.It connects your PCI-compliant server or workstation to a Gigabit Ethernet network,incorporating a new technology that transfers data at a rate of 1 Gbps or 1000 megabits per second (Mbps) over standard Category 5 cables.

Benefits

Performance is optimized and network overhead on the host system is minimized with the use of the GA622T Copper Gigabit Ethernet Card.

The GA622T has demonstrated interoperability with all major Gigabit Ethernet equipment on the market that is compliant with IEEE 802.3ab standards and should work with most non-compliant Gigabit Ethernet products. In addition,because the GA622T uses standard Ethernet frame and Media Access Control (MAC) formats, it provides full compatibility with Fast Ethernet network equipment through network switches from a variety of vendors,including NETGEAR.

Windows 95OSR2®,Windows 98®,Windows NT®,Windows 2000®,

,Novell NetWare®,or Red Hat Linux®environment.

Features

The key features of the GA622T Copper Gigabit Ethernet Card are:

• Full-duplex operation (2,000 Mbps:1,000 Mbps each way) with DMA (Direct Memory Access) Gigabit Ethernet interface (IEEE 802.3ab)

• RJ-45 connector for Category 5 unshielded twisted pair (UTP) cable

introduction 1-1

• Interoperability with existing Fast Ethernet equipment compliance with the following standards and protocols:

– IEEE 802.3ab Gigabit Ethernet – IEEE 802.3u Fast Ethernet – IEEE 802.3u Auto Negotiation – IEEE 802.3x Flow Control

• Standard Ethernet frame size (up to 1,518 bytes)

• Jumbo frames support

• Adaptive interrupt frequency

• Adjustable interrupt hold-off time to minimize CPU utilization, therefore

maximizing PCI bus and network throughput

• 33/66 MHz, 32/64-bit PCI bus mas ter (Local Bus Revision 2.2 compliant) with adaptive DMA channels

• Two independent DMA channels for simultaneous read and write operations; as a bus master,the network card requests access to the PCI bus instead of waiting to be polled

• Software driver support for Windows95OSR2,Windows 98,Windows NT, Windows 2000,Windows Me,NetWare 4.2,5.0, 5.1, and Red Hat Linux 6.1 and 6.2

• Universal dual-voltage signaling (3.3 V and 5 V)

Preparing to Install Your GA622T Copper Gigabit Ethernet Card

Follow the instructions provided in this section for installing the GA622T Copper Gigabit Ethernet Card in your server or workstation.For additional information about performing these tasks on your particular system,refer to the manuals included with your system hardware.

Before installing your Gigabit Ethernet Card:

1. Make sure that your system meets the hardware and software requirements provided in Table 2-1.

2. Make sure that your system uses the latest BIOS.

3. Turn off the power to your PC.

• If you are running Windows,close all applications and click Start from the

desktop menu, select Shut Down,and then s elect Shut down the computer.

• If you are running NetWare, us e the following commands to shut down the

server functions and reach the DOS prompt:

server_name: down server_name: exit

hardware installation 2-6

Danger:You are installing the card in a machine that operates with voltages that can be dangerous.Follow the steps after this warning to protect yourself and to prevent damage to the PC components.

4. Protect yourself,the card, and your server by taking these precautions:

• Shut down the server software and turn off the power to your server.

• Use only insulated or non-conducting tools.

• Hold the Gigabit Ethernet Card by the edges and place it on an antistatic

surface only.

• Check the card for visible signs of damage, particularly to the connector on

the edge of the card.Never attempt to install a damaged card.

Installing Your GA622T Copper Gigabit Ethernet Card

To install your GA622T Copper Gigabit Ethernet Card:

1. Remove the PC cover.

2. Choose an available 32-bit or 64-bit PCI expansion slot (PCI slots are usually the shorter slots) and remove the corresponding back plate from the PC chassis.

3. Insert the card into the PCI expansion slot.

Note:To avoid damaging any components on the card,handle it by the edges, using your thumbs to push it securely into the PCI slot.Do not us e excessive force,but make sure the card is fully inserted into the slot to prevent the PC operating system from freezing at startup.

The connector dock in a 32-bit PCI slot is shorter than in a 64-bit PCI slot. When installed in a 32-bit PCI slot,part of the connec tor edge remains undocked.This situation is normal.

4. Fasten the card to the rear of the computer chassis by tightening the screw that is on the PC.

5. Replace the PC cover and reconnect the power cord to the PC.

hardware installation 2-7

Connecting the Network Cables

The GA622T has one RJ-45 connector used for attaching the system to an Ethernet copper-wire segment.The card will automatically negotiate the fastest connection speed and duplex possible.If a specific speed or duplex is desired, the card can be placed into one of the supported modes: 1000 Mbps full duplex; 100 Mbps full duplex;100 Mbps half duplex.

1. Prepare an appropriate cable. Table 2-3 lists the cable characteristics for connecting to 100/1000BASE-Tports.

Table 2-3. GA622T (100/1000BASE-T) Cable Characteristics

Port T ype Connector Media Maxi mum Distance

100/1000BASE-T RJ-45 CAT 5 UTP/CAT 5e UTP 325 feet (100 meters)

Note:1000BASE-T signaling requires four twisted pairs of Category 5 balanced cabling,as specified in ISO/IEC 11801:1995 and ANSI/EIA/TIA-568-A (1995) and tested using procedures defined in TIA/EIA TSB95.

2. Connect one end of the cable to the GA622T Copper Gigabit Ethernet Card.

3. Connect the other end of the cable to an RJ-45 Ethernet network port.

4. Turn on power to the PC and then to the connected device.

5. Verify that one of the two link speed LEDs is on, indicating that there is a good link to the card.

Note:See Table 2-2 for a description of port LED operation.See Chapters 3 through 7 for driver installation and configuration instructions.

CHAPTER 3: WINDOWS 95OSR2/98/ME DRIVER SOFTWARE

This chapter provides information about the Microsoft Windows 95OSR2/98/Me driver software.

This chapter also describes how to:

• Install the driver software in the Windows 98 environment

• Move the card to a different slot

Note:The specific steps and screen shots used in this chapter refer to a computer with Windows 98 installed, bu t the information and procedures shown here apply to computers with Windows 950SR2 and Windows Me.

Installing the Driver Software

A network driver must be installed before the card can be used with your Windows 98 system.

Note:The Gigabit Ethernet card must be physically installed in your system prior to installing the driver software.See Chapter 2 “Hardware Installation,” for details.

When the Windows 98 System first boots up after installing a new hardware device, such as a GA622T Copper Gigabit Ethernet Card,the system automatically detects the new hardware and prompts you to install the driver software for the device.
