The 3Comâ Fast EtherLinkâ Parallel Taskingâ 10/100BASE-T4
PCI adapter is a 32-bit adapter for use in a personal computer
with a Peripheral Component Interconnect (PCI) computer bus.
It operates whether or not bus mastering is enabled.
This adapter (model number 3C595-T4) is a dual-speed adapter
that can be connected to an Ethernet or Fast Ethernet network
with a single connection over unshielded twisted-pair (UTP)
cable. The adapter supports all UTP cable types, including
Category 3, 4, and 5 UTP as well as screened Category 5 UTP.
For 10BASE-T operation, the 10/100BASE-T4 adapter requires
two pairs of Category 3, 4, or 5 UTP. For 100BASE-T4 operation,
the 10/100BASE-T4 requires four pairs of Category 3, 4, or 5 UTP.
The adapter automatically senses and switches to either
10 Mbps or 100 Mbps operation depending on the type of
hub to which the adapter is connected, as follows:
■
■
When the adapter is connected to a hub that supports 10BASE-T
Ethernet (10 Mbps), it switches to a network speed of 10 Mbps.
When the adapter is connected to a hub that supports
100BASE-T4 Fast Ethernet, it switches to a network speed of
100 Mbps.
The bus master drivers supplied with this adapter are
compatible with the Fast EtherLink 10/100BASE-TX PCI and
EISA adapters. The bus master drivers shipped on the 3C59X
EtherDiskâ diskette are compatible with the 3C59X family of
adapters; they are not backward-compatible with the 3C5X9
family of EtherLink III adapters.
The computer’s PCI BIOS automatically configures the I/O port
address and IRQ. All other required parameters are set to
factory-default values.

CHAPTER 1: INTRODUCTION
PCI Technology
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.
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 Fast Ethernet PCI T4
adapter is a bus master device that can transfer information
directly to system memory without interrupting the system
processor.
The PCI specification supports the following:
■
High performance. The PCI bus runs at a clock speed of
33 MHz and employs a 32-bit data bus that supports multiple
peripheral components and add-on cards at a peak bandwidth
of 132 Mbps, up to an order of magnitude greater than that of
other PC buses (ISA, EISA, or 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 and EISA buses in the same chassis.
For detailed information about the PCI local bus, consult the
PCI specification.

Miscellaneous checks
The 3Com diagnostic program is a DOS program. If you are
running an operating system or interface other than DOS,
refer to the section “Accessing DOS” in Chapter 3.
Troubleshooting with the Diagnostic Tests
The diagnostic tests on the 3C59X EtherDisk diskette check the
adapter’s overall operation and permit the isolation of faults.
You can run the diagnostic tests after installing the
10/100BASE-T4 PCI adapter, or when a fault is suspected.
If the tests in their default configuration do not isolate the
problem, you can change the test parameters to meet specific
situations.

CHAPTER 4: PERFORMING TROUBLESHOOTING AND DIAGNOSTIC TESTS
Before Running the Tests
When the DOS operating system first loads, it executes the
AUTOEXEC.BAT and CONFIG.SYS files. These files are user-
definable files that set up the computer environment and
may also load memory managers and drivers into memory.
If you are using DOS 6.x in a plain DOS environment, you can
bypass the CONFIG.SYS and AUTOEXEC.BAT files by holding
down the right shift key while starting the computer. If you
are running under DOS 6.2, pressing [F5] while starting the
computer will also bypass the same two files.
After performing the diagnostic tests, reboot your computer.
Types of Tests
The diagnostic tests are divided into three groups, of which
only the Group 1 and Group 3 tests apply to the
Fast EtherLink 10/100BASE-T4 PCI adapter.
The Group 1 test checks the physical components and
circuitry on the adapter. These tests are run as default tests.
The Group 2 test (Network Loopback Test) is not used on
twisted-pair adapters such as the Fast EtherLink 10/100BASE-T4
PCI adapter.
The Group 3 test (the Echo Exchange Test) tests the adapter’s
ability to transmit and receive data while on the network.
CAUTION: Running the Group 3 test while connected to an
active network can cause intermittent failures. To avoid this,
connect to an inactive network on which only the computer
being tested is operating.
If you run the diagnostic tests successfully, you rule out a
hardware failure on the computer. If the adapter passes all
the tests and there still appears to be a problem, look at
cabling, software, and other issues that affect functionality on
the network.

Running the Group 3 Test
The Group 3 test (Echo Exchange Test) tests the adapter’s
ability to transmit and receive data while on the network.
To run the Group 3 test on the network, you need a second
computer set up as an echo server. The echo server receives
packets from the adapter being tested and echoes them
back to the adapter.
The second computer must contain a 3Com adapter running
at the same speed as the Fast EtherLink 10/100BASE-T4 PCI
adapter (10 Mbps or 100 Mbps). The diagnostic program
that comes with the Fast EtherLink PCI adapter supports the
EtherLink III echo server diagnostic program.

Adapter Cabling Requirements
When properly connected to a 10BASE-T network, the
Fast EtherLink 10/100BASE-T4 PCI adapter operates in 10BASE-T
mode and requires standard 10BASE-T cable topologies and
types, including 2 pairs of Category 3, 4, or 5 UTP for 10 Mbps.
When properly connected to a 100BASE-T4 network, the
Fast EtherLink PCI adapter operates in 100BASE-T4 mode and
requires 4 pairs of Category 3, 4, or 5 UTP for 100 Mbps.
In either case, the cable, quality, distance, and connectors must
comply with the EIA/TIA 568 “Commercial Building Wiring
Standard” and the Technical Services Bulletin TSB38 standards.

APPENDIX A: CABLING
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, token ring,
and other network topologies.
The Electronic Industries Association/Telecommunications
Industries Association (EIA/TIA) defines the following five
categories of twisted-pair cable:
■
■
Category 1—Traditional telephone cable.
Category 2—Cable certified for data transmissions up to
4 MHZ.
■
Category 3—Used for voice and data transmission up to
16 Mbps. The cable has four pairs of wires and three twists
per foot. Category 3 is the most common type of previously
installed cable found in corporate wiring schemes and
normally contains 4 pairs in a bundle.
■
■
Category 4—Used for voice and data transmission up to
20 Mbps. The cable normally has four pairs of wire. This grade
of UTP is not common.
Category 5—Used for voice and data transmission up to
100 Mbps. The cable normally has four pairs of copper wire.
Category 5 is the most popular cable used in new
installations today.

10BASE-T Operation
A-3
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 maximum station separation of 2.8 kilometers (1.7 miles)
using fiber
■
■
A broadcast architecture
A specific media-access control (MAC) scheme
The specified networking technology for Ethernet is its MAC
protocol called Carrier Sense Multiple Access with Collision
Detection (CSMA/CD). Ethernet uses CSMA/CD to prevent
network failures or collisions when two devices try to access
the network at the same time.
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 being modulated onto separate carrier
frequencies. This is a feature of the Ethernet architecture.
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 328 feet (100 meters) from the node to the hub.
The 10BASE-T four-repeater (hub) rule states that you can use
no more than four repeaters between major LAN segments.
If you add a fifth repeater, the timing of the packets can be
impaired and the CSMA/CD media-sharing scheme may
break down.

APPENDIX A: CABLING
100BASE-T Standard
The 100BASE-T standard defines a network architecture
based on the 10BASE-T standard that retains almost all of the
original IEEE 802.3 Ethernet specification, while greatly
increasing the network’s overall throughput.
100BASE-T has the following similarities to 10BASE-T:
Uses the same CSMA/CD access method and MAC functions
Retains a hub-based architecture
■
■
■
■
Runs over unshielded twisted-pair or fiber cabling
Employs the same network management tools
The maximum span of a 100BASE-T network using only
twisted-pair cable is 205 meters (672.4 feet).
100BASE-T media specifications allow Fast Ethernet to run on
the most common Ethernet wiring, including Categories 3, 4,
and 5 unshielded twisted-pair, shielded twisted-pair, and fiber.
100BASE-TX Operation
100BASE-TX designates the IEEE 802.3 specification for
100 Mbps with CSMA/CD over two pairs of Category 5 UTP
or STP wire. Most 100BASE-TX equipment only supports
100 ohm UTP cable. The pairs of wires used for transmitting
and receiving signals are the same as those used for
10BASE-T. This means that the same cabling used for
10BASE-T can be used for 100BASE-TX with no change to
cable termination. Also, the connectors used for 100BASE-TX
at the hub or end station are the common Category 5
certified RJ-45 connector for UTP.

100BASE-T Standard
A-5
100BASE-T4 Operation
100BASE-T4 is the IEEE 802.3 specification for Ethernet
signaling for 100 Mbps over four pairs of Category 3 or better
UTP cable.This physical layer standard was specifically defined
to allow 100BASE-T to be deployed over the large installed
base of Category 3 voice-grade UTP.
100BASE-T4 uses four pairs of Category 3, 4, or 5 UTP cable, at
distances of up to 100 meters. Transmission requires four pairs
of cable to lower emissions and meet FCC requirements. You
must have four pairs of UTP available for each node to run
100BASE-T4.
100BASE-FX Operation
100BASE-FX is the IEEE 802.3 specification for 100 Mbps Ethernet
signaling over two strands of fiber cabling. 100BASE-FX is used
for transmissions over extended distances (up to 2 kilometers
[1.24 miles] between nodes), downlinks, and backbones, and is
especially useful in any environment subject to electrical
interference.

* This option specifies whether to optimize the network driver for a normal environment, a
minimized CPU utilization environment, or a maximized network performance environment. You
may choose to use a larger percentage of CPU resources under DOS in order to improve
network throughput.
In multitasking environments, choosing the Minimize CPU Utilization option saves the resources
of the CPU for other tasks. If no other applications are making major demands on CPU resources,
you may choose the Maximize Network Performance option.
† Full duplex operation is possible only in 10 Mbps operation when used in an environment
where the switch supports it. Do not enable the Full Duplex option unless your switching hub is
set for full duplex.
Changing Software Settings
To change the software option settings, follow these steps:
If this computer is an operating server, notify all users of the
server to save their work and log out from the network. The
Configuration and Diagnostic Program disrupts the normal
operation of servers and workstations, so work that is not
