GETTING STARTED
The 3Com® OfficeConnect® Fast Ethernet Network
Interface Card (NIC) allows you to connect your personal
computer (PC) to an Ethernet (10BASE-T) or Fast Ethernet
(100BASE-TX) network.
The OfficeConnect NIC is specifically designed for the
small office/home office environment.
What This Guide Covers
This guide provides all the information you need to install
the OfficeConnect NIC and connect it to a network. It tells
you how to:
■
Insert the NIC into a PC.
■
Attach the PC to a network port on a hub or switch.
■
Install the NIC network driver and diagnostics software
on the PC.
■
Configure the NIC on the PC.
■
Troubleshoot problems you may encounter with
the NIC.
What This Chapter Covers
This chapter provides a brief introduction to networking
and describes the features of your OfficeConnect NIC.
If you’re already familiar with basic networking concepts,
you can start with Chapter 2, “Installing the
Network Interface Card.”
12
CHAPTER 1: GETTING STARTED
Understanding Networking
A computer network is a group of computers and other
associated devices, such as printers, fax machines, and
modems, that are connected to one another so they can
share resources and information.
A network allows you to:
■
Share resources — You and others on the network can
share resources, such as a data file or directory, hard
disk drive, printer, scanner, or modem.
■
Exchange information — You can communicate and
exchange information, such as e-mail, with all
designated users on the network.
■
Provide server support — You can store files and
applications in a central location on one PC hard drive,
where they can be accessed by any network users who
have the proper authorization.
Figure 1 shows a sample network composed of two PCs, a
printer, and a hub.

Understanding Networking
13
Every network requires special software, called a network
operating system (NOS) (such as Windows NT or NetWare),
to control the flow of information between users.
Each PC that you want to connect as part of the network
must have an operating system (such as Windows 95,
Windows 98, or Windows NT) that can communicate with
the NOS.
In a peer-to-peer networking architecture, the operating
system that is installed on each PC acts as the NOS. In a
client/server networking architecture, the operating system
that is installed on each client PC communicates with the
NOS, which is installed on the server PC.
There are two basic types of small business network
architectures: peer-to-peer and client/server.
Peer-to-Peer Networks
A peer-to-peer network is generally suited for home and
small office use. This type of network is the easiest to
install, accommodates up to about five PCs, and is
suitable for sharing applications, data, printers, and
other localized resources.
The PCs on a peer-to-peer network are connected directly to
one other or to a central point, usually a device called a hub.
Unlike a client/server network, a peer-to-peer network allows
users to share information without relying on a centralized
server. Figure 1 is an example of a peer-to-peer network.
The PCs on a peer-to-peer network require an operating
system such as Windows 95 or Windows 98. This operating
system acts as the NOS.
For more information on peer-to-peer networking, see the
Network Assistant CD included in your package.
14
CHAPTER 1: GETTING STARTED
Client/Server Networks
A client/server network is ideal for organizations that
require fast network access for large applications such
as multimedia, databases, and video.
In a client/server network, all shared applications and files
are stored on one central computer known as the server.
Network users (client PCs) can store their own files on their
own PCs, and then use the server to access shared files and
peripherals, such as printers, fax machines, and modems.
The client PCs on a client/server network require an
operating system such as Windows 95, Windows 98, or
Windows NT. The servers on a client/server network require
a NOS such as Windows NT or NetWare.
Ethernet and Fast Ethernet Networking Protocols
Ethernet and Fast Ethernet are local area network (LAN)
protocols, or specifications, that define the signaling of the
network and specify how data is placed on and retrieved
from the network.
Fast Ethernet is the same as Ethernet, except for the speed:
■
Ethernet has a data transfer rate of 10 Mbps (megabits
per second).
■
Fast Ethernet has a data transfer rate of 100 Mbps.
The OfficeConnect NIC is compatible with both Ethernet
and Fast Ethernet networks. It automatically connects to
the network at 10 Mbps or 100 Mbps, depending on the
speed of the connected network hub or switch.
For more information on Ethernet and Fast Ethernet, see
Appendix A.
For more information on networking, see the
Network Assistant CD included in your package.
Understanding Network Interface Cards
15
Understanding Network Interface Cards
A network interface card (NIC) is a printed circuit board
that plugs into a PC expansion slot in your computer to
provide a connection to a network.
Once the NIC is installed in your PC, you connect it to the
network media (cabling, such as unshielded twisted-pair
[UTP]), which in turn connects to all the devices on
the network.
About the OfficeConnect NIC
The OfficeConnect NIC is a 10/100 Mbps PCI (Peripheral
Component Interconnect) NIC. It connects your PC to a
10 Mbps Ethernet or 100 Mbps Fast Ethernet network.

CHAPTER 1: GETTING STARTED
After the NIC is installed, these LEDs show whether there’s
an active connection between the NIC and the network,
and the speed at which you’re connected. (See
“Interpreting the LEDs” in Chapter 4 for more
information.)
Required Hardware
You can install the OfficeConnect NIC in any IBM-compatible
PC with an available PCI expansion slot. Almost all
PCs currently on the market have such slots. (See “Inserting
the NIC” in Chapter 2 for more information about
PCI expansion slots.)
Required Cabling
You need an unshielded twisted-pair cable with RJ-45
connectors on both ends to connect the OfficeConnect NIC
to the network. This cable is not supplied with the NIC.
■
If you’re connecting to a 10 Mbps Ethernet network,
use a Category 3, 4, or 5 UTP cable.
■
If you’re connecting to a 100 Mbps Fast Ethernet
network, use a Category 5 UTP cable.
The maximum Ethernet cable length allowed between
the NIC and the network device to which it is connected
is 328 feet (100 meters).
For more information on cabling, see “Cabling
Requirements” in Appendix A.
Required Software
The OfficeConnect NIC is compatible with the following
operating systems:
■
Windows 95
■
Windows 98
■
Windows NT versions 4.0 and 3.51
You can use the OfficeConnect NIC to connect to both
Microsoft and NetWare network environments.
The EtherDisk diskette included in your package contains the
software (configuration programs, diagnostic programs, and
device drivers) that allows your NIC to work with all of the
operating systems mentioned in this section.

INSTALLING THE
NETWORK INTERFACE CARD
This chapter explains how to install the OfficeConnect NIC
in your PC and connect it to an Ethernet or Fast Ethernet
network.
Preparing for Installation
Before you install the OfficeConnect NIC, make sure
that you have the following items:
■
OfficeConnect 10/100 Fast Ethernet NIC
■
OfficeConnect EtherDisk diskette
If any of these items are damaged or missing, contact
your shipper or network supplier.
You also need an unshielded twisted-pair (UTP) cable
with RJ-45 connectors on both ends to connect the
OfficeConnect NIC to an Ethernet or Fast Ethernet
network. This cable is not supplied with the NIC.
Table 3 specifies the type of cable that you need for the
type of network that you are connecting to (10 Mbps
Ethernet or 100 Mbps Fast Ethernet).
The maximum distance between any two devices on your
network can be no more than 328 feet (100 meters).

CHAPTER 2: INSTALLING THE NETWORK INTERFACE CARD
Inserting the NIC
To insert the OfficeConnect NIC in your PC:
1 Remove all jewelry from your hands and wrists.
CAUTION: The NIC is packed in an antistatic container
to protect it during shipment. To avoid damaging any
static-sensitive components on the NIC, before you remove
it from the container, touch the metal chassis of your PC to
discharge static electricity from your body. Also, be careful
to handle the NIC by its edges only.
2 Turn the power off to the PC. Unplug the
power cable. Detach all other cables from the PC.
3 Remove the PC cover.
See your PC documentation for details.
4 Find an empty PCI expansion slot and remove the
corresponding slot cover. Keep the backplate screw.
The OfficeConnect NIC works in a PCI expansion slot. Some
PCs have three types of expansion slots: PCI, ISA, and EISA.
PCI slots are usually white and shorter than the other
expansion slots (see Figure 3). ISA slots are usually black.
EISA slots are usually brown, and are as long as ISA slots. If
you’re not sure what type of expansion slots your PC has,
see your PC documentation for details.
For more information on PCI expansion slots, see
“Frequently Asked Questions” in Chapter 4.
5 Carefully insert the NIC into the slot, pressing firmly
with steady pressure until it’s seated properly.
The NIC’s metal backplate should be positioned so that you
can easily fasten it with the backplate screw. You shouldn’t
be able to see any of the NIC’s edge connector.
Not all PCs have expansion slots positioned on the bottom
of the chassis, as shown in Figure 3. You may be using a PC
with the expansion slots on a vertical panel. If so, follow
the same insertion instructions, except install the NIC
horizontally. If it helps, position the PC on its side
temporarily to insert the NIC securely.

Table 5 Frequently Asked Questions (continued)
Question
Answer
How do I remove
the 3Com icon from
my Windows
system tray?
1 Double-click the 3Com icon to start the 3Com NIC
Diagnostics program.
2 In the bottom-right corner of the main window, click the
Enable Tray Control check box to remove the check mark.
3 Exit the program and the icon will not appear anymore.
Which PCI slot
should I use for my
OfficeConnect NIC?
3Com PCI NICs, such as the OfficeConnect NIC, are
designed to work in any bus-mastering PCI slot, preferably
slot 1. Normally, slot 1 is marked on the PC motherboard
and is located closest to the computer power supply.
Avoid any PCI slot next to an ISA slot. This is often a
shared slot and does not support bus mastering. The
NICs perform best in those slots that support
bus-mastering data transfers.
Some PCs have three types of expansion slots: PCI, ISA,
and EISA. PCI slots are usually white and shorter than the
other expansion slots (see Figure 3 in Chapter 2). ISA slots
are usually black. EISA slots are usually brown, and are as
long as ISA slots. If you’re not sure what type of expansion
slots your PC has, see your PC documentation for details.
Also refer to your PC manual for information on which
slots support bus-mastering data transfers.
Do I have to configure PCI is a self-configuring bus architecture. Most of the
the OfficeConnect NIC? time you only need to install the NIC in your PC; PCI does
the rest. However, on some PCI computers, you may be
required to configure the computer’s BIOS manually after
installing your PCI NIC. Refer to your PC documentation
for more information about your PC’s BIOS.
What interrupts
should I avoid?
You should avoid using any interrupts used by ISA/EISA
boards that do not properly support shared interrupts
(level-triggered). If you don’t know or aren’t sure whether
other devices or adapters in your PC support shared
interrupts, then avoid using them.
Avoid using the same interrupt as your local hard drive
(normally IRQ 14 for IDE drives and IRQ 11 for most SCSI
host adapters), because not all hard drives support shared
interrupts at this time. Avoid using 9 because it cascades
with 2.
Does the OfficeConnect Yes, the OfficeConnect NIC supports full-duplex operation
NIC support
at 10 Mbps and 100 Mbps.
full-duplex?
Full-duplex is the ability of a device or line to transmit data
simultaneously in both directions (the PC is sending and
receiving data at the same time).

APPENDIX A: SPECIFICATIONS AND CABLING REQUIREMENTS
Unshielded Twisted-Pair Cable
Twisted-pair cable consists of copper wires surrounded by
an insulator. Two wires are twisted together (the twisting
prevents interference problems) to form a pair, and the pair
forms a circuit that can transmit data. A cable is a bundle of
one or more twisted pairs surrounded by an insulator.
Unshielded twisted pair (UTP) is the most commonly used
type of twisted-pair cable. Shielded twisted pair (STP)
provides protection against crosstalk. Twisted-pair cable is
now commonly used in Ethernet, Fast Ethernet, and other
network topologies.
The EIA/TIA defines five categories of unshielded
twisted-pair cable (see Table 7).
Table 7 Unshielded Twisted-pair Cable Categories
Category
Use
1
Traditional telephone cable.
2
Data transmissions up to 4 MHz.
3
Voice and data transmission up to 25 MHz. The cable
typically has four pairs of wires. Category 3 is the
most common type of installed cable found in older
corporate wiring schemes.
4
Voice and data transmission up to 33 MHz. The cable
normally has four pairs of wire. This grade of UTP
isn’t common.
5
Voice and data transmission up to 125 MHz. The cable
normally has four pairs of copper wire and three twists
per foot. Category 5 UTP is the most popular cable
used in new installations today.
10BASE-T Operation
10BASE-T is the Institute of Electrical and Electronics
Engineers (IEEE) 802.3 standard for Ethernet signaling over
unshielded twisted-pair wire at 10 Mbps.
Ethernet, as the most widely used network protocol, uses
10BASE-T as its primary cabling scheme. Ethernet’s
characteristics include:
■
A data rate of 10 Mbps
■
A broadcast architecture
■
A specific media-access control (MAC) scheme
Cabling Requirements
59
10BASE-T Specifications
The 10BASE-T name indicates a signaling speed of
10 Mbps and twisted-pair wiring. Base stands for
baseband, which denotes a technique for transmitting
signals as direct-current pulses rather than modulating
them onto separate carrier frequencies.
A wiring topology using 10BASE-T specifies a wiring hub,
cable arranged in a star configuration, and unshielded
twisted-pair cable. Each node has a separate cable run that
must not exceed 100 meters (328 ft) from the node to
the hub.
100BASE-TX Operation
100BASE-TX is the Institute of Electrical and Electronics
Engineers (IEEE) 802.3u standard for Ethernet signaling
over unshielded twisted-pair wire at 100 Mbps.
Fast Ethernet uses 100BASE-TX as its primary cabling
scheme. Fast Ethernet’s characteristics include:
■
A data rate of 100 Mbps
■
A broadcast architecture
■
A specific media-access control (MAC) scheme

newer BIOS, you replace the ROM chip in your PC with
an upgraded chip.
bus mastering
Method for accessing the PC bus in which a card or
device takes control of the bus in order to send data onto
the bus directly, without help from the central processing
unit (CPU).
client/server network
Networking architecture in which all shared applications
and files are stored on one central computer known as a
server. Network users (known as clients) can store their
own files on their own PCs and then use the server to
access shared files and peripherals, such as printers, fax
machines, and modems.
Ethernet
IEEE standard network protocol that specifies how data
is placed on and retrieved from a common transmission
medium. Ethernet has a transfer rate of 10 Mbps.
68
GLOSSARY
Fast Ethernet
100 Mbps technology based on the 10BASE-T Ethernet
network protocol.
full-duplex
Communication setup in which a device or line transmits
data simultaneously in both directions (the PC is sending
and receiving data at the same time).
half-duplex
Communication setup in which a device or line transmits
data in only one direction at a time.
hub
Device that serves as the central location for attaching
wires from workstations. A hub can be passive, when there
is no amplication of the signals; or active, when it is used
like a repeater to provide an extension of the cable that
connects to a workstation.
network
Group of computers and other associated devices, such as
printers, fax machines, and modems, that are connected to
one another so they can share resources and information.
network driver optimization
Driver option that specifies how to optimize performance
of the network driver for your environment.
network operating system (NOS)
System software that runs on the network’s file server, with
a smaller component that runs on each device attached to

driver architecture and interfaces that let a PC support
NICs. This architecture provides a standardized way to write
drivers for network NICs.
GLOSSARY
69
PCI
Peripheral Component Interconnect. Advanced,
high-performance local bus that supports multiple peripheral
devices. A local bus is one that is connected directly to the
PC’s central processing unit (CPU).
peer-to-peer network
Networking architecture in which PCs and other devices,
such as printers and fax machines, are connected directly
to one another or to a central point, usually a hub. Unlike a
client/server network, a peer-to-peer network does not use
a server.
server
PC that provides access to resources or services such as files,
printers, fax machines, and e-mail on a client/server network.
Servers may be distinguished by the elements to which they
control access (for example, on a client/server network there
may be a print server, file server, or communications server).
switch
Device that can direct network traffic among several
Ethernet networks.
unshielded twisted pair (UTP) cabling
Most commonly used type of twisted-pair cable.
Twisted-pair cable consists of copper wires surrounded by
an insulator. Two wires are twisted together (the twisting
prevents interference problems) to form a pair, and the pair
forms a circuit that can transmit data. A cable is a bundle of
one or more twisted pairs surrounded by an insulator.

rights which may vary depending on local law.
