CHAPTER 1: INTRODUCTION
Congratulations on your purchase of the NETGEAR®GA621 Fiber 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 GA621 for operation within a Microsoft
®
Windo ws®95OSR2,Wi ndo ws®98,Windows®NT,Windows®2000,Windows®Me,
Novell
®
NetWare,or Red Hat®Linux environment.
This chapter provides information about the features of the GA621. 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 62.5/125 or 50/125 Micron multimod e fiber with SC
connectors.
Benefits
Performance is optimized and network overhead on the host system is minimized
with the use of the GA621 Fiber Gigabit Ethernet Card.
The GA621 has demonstrated interoperability with all major Gigabit Ethernet equipment on the market that is compliant with IEEE 802.3z standards. In addition,
because the GA621 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.
Features
The key features of the GA621 Fiber Gigabit Ethernet Card are:
• Full-duplex operation (2,000 Mbps:1,000 Mbps each way) with DMA (Direct
Memory Access) Gigabit Ethernet interface (IEEE 802.3z)
introduction 1-2
• Duplex SC fiber connector for 62.5-micron or 50-micron multimode fiber cable
• Interoperability with existing Fast Ethernet equipment compliance with the
following standards and protocols:
– IEEE 802.3z 1000BASE-SX Gigabit Ethernet
– IEEE 802.3u Fast Ethernet
• Standard Ethernet frame size (up to 1,518 bytes)
• Jumbo frames support
• 33/66 MHz, 32/64-bit PCI bus master (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 Windows 95 OSR2,Windows 98,Windows NT,
Windows 2000,Windows Me,NetWare 4.2,5.0, 5.1, and Red Hat Linux 6.0, 6.1,
6.2,7.0 and 7.1.
• Universal dual-voltage signaling (3.3 V and 5 V)

Hardware Description
As illustrated in Figure 2-1,the GA621 Fiber Gigabit Ethernet Card has an SC
connector port and two port LEDs.
Figure 2-1. Front Panel of Model GA621 Gigabit Ethernet Card
The front panel of the GA621 has two LEDs:one LED to indicate the link is active
and one LED for data transfer status. Once the hard ware and its driver software are
properly installed on your system,the LEDs indicate the conditions described in Table
2-2.
Table 2-2. GA621 LEDs
Label Activity Description
DATA Blinking Brief bursts of data detected on the port
On Streams of data detected on the port
Off No data detected on the port
LINK On Good 1000 Mbps Gigabit Ethernet link
Off No 1000 Mbps link;possible bad cable,bad connector,or configuration
mismatch
Preparing to Install Your GA621 Fiber Gigabit Ethernet Card
Follow the instructions provided in this section for installing the GA621 Fiber Gigabit
Ethernet Card in your s erver 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
hardware installation 2-7
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 GA621 Fiber Gigabit Ethernet Card
To install your GA621 Fiber 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.

Connecting the Network Cables
The GA621 has one SC port that can be used with either 62.5/125-Micron multimode fiber or with 50/125-Micron multimod e fiber.
1. Prepare an appropriate cable.
Table 2-3 lists the cable characteristics for connecting to 1000BASE-SXport.
Table 2-3. GA621 (1000BASE-SX) Cable Characteristics
Port T ype Connector Media Maxi mum Distance
1000BASE-SX SC 62.5/125-Micron multimode fiber 260 meters
1000BASE-SX SC 50/125-Micron multimode fiber 550 meters
2. Connect one end of the cable to the GA621 Fiber Gigabit Ethernet Card.
3. Connect the other end of the cable to an SC Ethernet network port.
4. Turn on power to the PC and then to the connected device.
5. Verify that the link 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.
