INTRODUCTION  
1
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.

and modifies the CONFIG.SYS and AUTOEXEC.BAT files. It  
automatically logs on to the server and updates the client  
software if your system administrator has already configured  
a 3Install account on the server. Instructions for configuring  
a 3Install account are contained in the README.TXT file  
located in the \QINSTALL\SERVER directory on the  
3C59X EtherDisk diskette.

PERFORMING  
TROUBLESHOOTING AND  
DIAGNOSTIC TESTS  
4
This chapter explains how to isolate and solve  
10/100BASE-T4 PCI adapter problems.  
Make sure that the adapter is correctly installed. (See Chapter 2  
for installation instructions.)  
This chapter contains information about the following topics:  
Diagnostic tests overview  
Starting the diagnostic program  
Getting help if a test fails  
Changing the test setup  
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.

4-2  
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.

Starting the Diagnostic Program  
4-3  
Starting the Diagnostic Program  
Always run diagnostic tests with no device drivers or memory  
managers (EMM386.EXE and HIMEM.SYS) installed. Whenever  
you plan to run the diagnostic tests, you must first start your  
computer from a DOS diskette containing no device drivers, or  
you must exit to DOS if you have an operating system other  
than DOS. (Refer to the section “Accessing DOS” in Chapter 3.)  
To use the 3C59X EtherDisk diskette Configuration and  
Diagnostic Program, follow these steps:

pressing [F1].  
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.

Setting Up an Echo Server  
To test 10 Mbps operation of the 10/100BASE-T4 PCI  
adapter, use a computer as an echo server that contains an  
EtherLink III adapter or another 10/100BASE-T4 PCI adapter.  
To test for 100 Mbps operation of the 10/100BASE-T4 PCI  
adapter, use another Fast EtherLink PCI adapter in the  
computer being used as the echo server.  
In either case, select the Echo Server menu item under the  
Test menu, and click Start to make the computer an echo  
server.  
If you are setting up an echo server on a computer with a  
10 Mbps 3Com adapter other than an EtherLink III adapter,  
follow these steps:

or improper installation. Complete the following steps to test  
the adapter further.  
CAUTION: Make sure to turn the power off and disconnect all  
cables from the adapter before inserting or removing it from  
the computer.  
Check the adapter installation by reviewing the installation  
instructions in Chapter 2.  
Make sure the adapter is seated correctly in the slot.  
Inspect all cables and connections.  
Make sure that the PCI slot containing the adapter is activated.  
PCI computers allow PCI slots to be activated or deactivated  
through the computer‘s BIOS setup, or in some cases, with a  
special PCI utility. Refer to your computer documentation for  
information about activating PCI slots.  
In addition, bus mastering is not supported on all PCI slots in  
all computers. The Fast EtherLink PCI adapter provides better  
performance in a bus master slot, but will work in a non-bus  
master slot. Refer to your computer documentation.  
The original slot may be defective.  
Make sure that you booted your computer under  
DOS version 3.1 or later, and that no device drivers or memory  
managers are loaded.

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.  
The maximum UTP cable distance is 100 meters (330 feet) at  
either speed.

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.

CONFIGURING SOFTWARE  
SETTINGS  
B
The Fast EtherLink 10/100BASE-T4 PCI adapter is automatically  
configured by the PCI’s computer’s BIOS with the following  
basic configuration parameters:  
I/O Port Address  
Interrupt Request Level (IRQ)  
This is done automatically when the computer with the  
installed Fast EtherLink PCI adapter is turned on for the first  
time after installation of the adapter. Other required  
parameters are preset on the adapter so that it will function  
without further action.  
Additional default settings can be changed in the following  
situations:  
You have a boot PROM.  
You want to manually select the network speed for the adapter.  
You want to optimize driver performance for Windows.  
You want to enable the Full Duplex option for 10 Mbps  
operation.  
The Full Duplex setting can only be utilized in a 10 Mbps  
network with a hub or a switch that supports it.  
Table B-1 lists each software option and the options’ default  
setting and available settings. Refer to the on-line help (press  
[F1] when the option is highlighted) for more information  
about each setting.

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.

GLOSSARY  
MAC  
Media access control. The operational scheme that gives  
each network node orderly access to the network cable.  
CSMA/CD is a MAC protocol that determines how nodes on  
the network share access to the cable.  
NDIS  
Network Driver Interface Specification. Defines the LAN Manager  
network driver architecture and interfaces that let a DOS or OS/2  
system support network adapters.This architecture provides a  
standardized way to write drivers for network adapters.  
NetWare  
A series of network operating systems and related products  
made by Novell, Inc.  
ODI driver  
Open Data-Link Interface. A MAC-level specification  
developed by Novell and Appleâ. Drivers complying with this  
specification can work with NetWare 2.x, 3.x, and 4.x. Like NDIS,  
ODI drivers support multiple protocols and adapters, and can  
be unloaded from memory to conserve conventional DOS  
RAM space.  
Parallel Tasking  
3Com’s third-generation Ethernet adapter architecture.  
Parallel Tasking technology accelerates data transfer by  
processing data packets simultaneously instead of  
sequentially. For example, when transmission is the task, the  
Parallel Tasking architecture begins to write data to the  
network even before an entire frame has been loaded into  
the adapter’s buffer memory. This permits complete  
parallelism in all data transfers.  
PCI  
Peripheral Component Interconnect. An advanced high-  
performance local bus that supports multiple peripheral  
devices. At 33 MHz, the PCI bus transfers 32 bits of data at up  
to 132 Mbps.

STP  
Shielded twisted-pair cable. Twisted-pair cabling with an  
overall shield to prevent the entry of outside interference,  
and individually shielded and twisted-pairs to prevent  
crosstalk.  
Transcend  
3Com’s integrated network management solution based on  
groups of logically related devices and including a variety of  
network management tools.  
Twisted-pair  
Wiring similar to that found in the telephone system,  
consisting of two insulated wires loosely twisted around each  
other to help cancel out induced noise in balanced circuits.  
UTP  
Unshielded twisted-pair cable. Twisted-pair cabling that does  
not have individual or overall shielding. The cable contains  
two or more pairs of twisted copper wires.
