INTRODUCTION

The IBM 10/100 Fast EtherLink® XL Adapters by 3Com
provide a high-performance connection to an Ethernet or
Fast Ethernet network. These adapters operate at 100
Mbps or 10 Mbps automatically, depending on the speed
of the connected hub.

Figure 1-1 3C905B-TX Adapter

There are two types of 3C905B-TX adapters: the 3C905B-TX
adapter with Remote Wake-Up and the 3C905B-TX-NM
adapter without Remote Wake-Up.

The 3Com Remote Wake-Up adapter (3C905B-TX), shown in
Figure 1-1, operates as a wake-up adapter only in PCs with
the Remote Wake-Up connector attached to the PC
motherboard. This adapter provides a network connection
with or without the Remote Wake-Up connector installed.

The 3C905B-TX-NM adapter does not have the Remote
Wake-Up connector or functionality.

1-2 CHAPTER 1: INTRODUCTION

Unless specifically indicated, the name 3C905B-TX is used
throughout this guide to refer to both adapters.

This chapter describes the 3C905B-TX adapter features and
PC and server requirements.

Industry-Leading Performance

The 3C905B-TX adapter provides the following
performance features:

■ Interactive Access technology to minimize CPU utilization

■ Parallel Tasking

low processor utilization

■ Full-duplex 10 Mbps and 100 Mbps support

■ Hardware IP checksum enabled for better Internet and

intranet performance

®

II architecture for high thr oughput and

■ Fast IP switching solution that allows you to

cost-effectively scale internetwork performance as
bandwidth requirements increase

■ 32-bit bus master design with full scatter gather and

infinite bursting performance

■ Flow control (IEEE 802.1x), which optimizes performance

in switched networks through efficient data transmissions

DynamicAccess Software

DynamicAccess® software delivers intelligence at the edge of
the network to optimize network performance and control.

DynamicAccess features include PACE™ Interactive Access
technology, dRMON (distributed RMON) support, and
support for PACE real-time and multimedia applications.

PACE class of service drivers enable prioritization of
multimedia and business-critical applications like video
conferencing and distance learning. With the 3Com PACE
drivers, you can set the class of service for each application.

The 3C905B-TX adapter ships with dRMON SmartAgent®
intelligent agents that collect remote management
information used by the Transcend® Edge Monitor System.
Together, they provide full RMON network management
information for both switched and Fast Ethernet networks.

Remote Wake-Up

Remote Wake-Up support is enabled for the 3C905B-TX
adapter. If you are using the 3C905B-TX adapter in a PC
that supports Remote Wake-Up through the PCI bus, the
adapter will respond to a remote Wake-Up command or
magic packet signal from a sleep state.

Installation and Configuration

The 3Com NIC Diagnostics program allows you to test
the 3C905B-TX adapter, configure it, and display the
adapter configuration information. If you are running DOS,
you cannot use this program.

The NIC Diagnostics Help system includes the 3C905B-TX
adapter Release Notes, Frequently Asked Questions, and
KnowledgeBase.

Remote Wake-Up 1-3

Microsoft Windows 95 detects the 3C905B-TX adapter and
installs the network driver from 3Com EtherDisk Diskette #2.

The AutoLink™ installation software automatically installs
all Novell NetWare DOS ODI client software into your
operating system.

10/100 Mbps Support

The single RJ-45 connector on the network cable supports
10 Mbps or 100 Mbps speeds.

NWay auto-negotiation enables the 3C905B-TX adapter to
automatically run at the speed that the connected hub
supports. The 3C905B-TX adapter works with products that
comply with IEEE 10BASE-T and 100BASE-TX specifications.

1-4 CHAPTER 1: INTRODUCTION

PC and Server Requirements

Your PC or server must have:

■ An 80386, 80486, or Pentium processor

■ An available bus mastering PCI slot

■ A minimum of 640K of memory

Make sure that you are running the latest BIOS for your PC or
server, even if your PC is new. Contact your PC manufacturer
for more information.

How Do I Install the 3C905B-TX Adapter?

To complete installation, install the adapter in your PC or
server, connect it to the network, and install the network
driver. The installation steps are depicted in Figure 1-2.

Proceed to Chapter 2 to install the 3C905B-TX adapter in
your PC or server and connect it to the network.

INSTALLING THE ADAPTER

There are two types of 3C905B-TX adapters: the 3C905B-TX
adapter and the 3C905B-TX-NM adapter. They are both
installed in your PC and connected to the network in exactly
the same way.

After you connect the 3C905B-TX adapter to the network,
you connect the Remote Wake-Up cable to the motherboar d.

Before you begin, make sure that you have the user guide
and the 3C905B-TX adapter EtherDisk diskettes, and that
your PC meets the requirements described in Chapter 1.

CAUTION: Each adapter is packed in an antistatic container
to protect it during shipment. Before handling the adapter,
touch the metal chassis of your PC. Maintain grounding by
wearing a wrist strap attached to the chassis. Handle the
adapter by its backplate and top edge. Do not touch the
edge connector.

To install the 3C905B-TX adapter in your PC or server and
connect it to the network, follow these steps:

1 Open the shipping container and inspect each item

for damage.

2 Remove all jewelry from your hands and wrists.

Use only insulated or nonconductive tools.
3 Unplug the PC and disconnect all cables.
4 Remove the PC cover.
5 Choose an empty bus mastering PCI slot.

A sample PCI slot is shown in Figure 2-1. If you do not know

how to identify a PCI slot, check your PC documentation or

ask your system administrator. In most PCs, slots 1 and 2 are

bus mastering slots. Use slot 1 for the 3C905B-TX adapter if

possible. If you have a video PCI card, install it in the last slot

(the one farthest from slot 1).

2-2 CHAPTER 2: INSTALLING THE ADAPTER

6 Unscrew the screw holding the PCI slot’s backplate

and remove it.

7 Insert the 3C905B-TX adapter into an empty PCI slot,

shown in Figure 2-1.

Make sure that the adapter is firmly seated in the slot.

8 Secure the adapter with the screw you removed

earlier.

If you are installing the Remote Wake-Up connector, go to
“Connecting the Remote Wake-Up Cable,” on page 2-4 at
the end of this chapter before replacing the PC cover.

Remote Wake-Up is only supported in systems that provide
a 3-pin header for a Wake-Up cable.

9 Replace the PC cover and reconnect all previously

connected cables.

10 Turn on the power to the PC.

11 Proceed to the next section, “Connecting to the

Network.”

Connecting to the Network

You must connect the adapter to the network before

installing the network driver. To connect the 3C905B-TX

adapter to the network cable, follow these steps:

1 Connect the network cable to the RJ-45 port on the

3C905B-TX adapter, as shown in Figure 2-2.

Connecting the Remote Wake-Up Cable

WARNING: Install the adapter in slot 1 in the PC (as
described earlier) before plugging in the 3-pin connector.
Only properly trained and authorized personnel should
perform service. Contact your PC manufacturer for
information about safe service techniques.

1 Insert the cable into the connector on the adapter,

shown in Figure 2-3.

Twist the cable twice before attaching the cable to the
motherboard.

2 Attach the cable to the connector on the PC

motherboard, as shown in Figure 2-3.

The connector is located in different locations depending
on the PC.
