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

EtherDisk

â 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.

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.

RJ-45 connector

Figure 2-2 Connecting Twisted-Pair Cable

The Fast EtherLink 10/100BASE-T4 PCI adapter is equipped with an on-board transceiver for connection to twisted-pair cable. To establish a valid 10 Mbps connection, the cable must be connected to a 10BASE-T hub. To establish a valid

100 Mbps connection, the cable must be connected to a

100BASE-T4 hub.

Connect the network cable as follows:

1 Make sure that the connector on your cable is wired appropriately for standard 10BASE-T or 100BASE-T4 adapters.

Connecting to the Network

2-5

100BASE-T4 connections use all 4 pairs of wire normally contained in a bundle of Category 3, 4, or 5 UTP cable. The

“straight through” connection should be made from the Fast

EtherLink PCI adapter through the cable and connectors to the hub. No crossover in the cable is required.

Refer to Appendix A for RJ-45 connector pin assignments.

2 Align the RJ-45 connector on the end of the twisted-pair cable with the notch on the adapter’s connector and insert it into the adapter connector.

3 For 100 Mbps operation, be sure the connection is to a

100BASE-T4 hub port.

1 Make sure that you have booted the computer under DOS, version 3.1 or later, and that your computer is connected

to the network, as detailed in Chapter 2.

2 Insert the EtherDisk diskette in a floppy drive on your computer and make that drive the active drive.

For example, if the floppy drive is A, type the following command:

A: [Enter]

3 At the prompt, type:

INSTALL [Enter]

Alternatively, at the prompt, type:

AUTOLINK [Enter]

If you type AUTOLINK instead of INSTALL, you will bypass the

EtherDisk diskette menu program (skipping steps 5 and 6)

and advance to step 7.

4 The first time you use the diskette to install an adapter, a license screen appears. To accept the terms and conditions of the 3Com end-user software license agreement, type the following:

Y

To view the full text of the license agreement, press [F1].

Once you have agreed to the terms and conditions of the

3Com license agreement, the license screen will not appear again.

The Auto Installation Information screen appears, as shown in

Auto installation may take a few moments. Several messages appear while the AutoLink program is running. A final message indicating successful installation appears.

If you experience problems that occur only when using the

AutoLink program, access the AUTOLINK.LOG file, as described

in the section “Getting Help If a Test Fails” in Chapter 4.

7 When the auto installation process is finished, remove the diskette and reboot the computer.

When you do this, a DOS ODI client starts.

This concludes the procedure for installing a single adapter in a NetWare DOS ODI client using the AutoLink program.

Multiple Adapters in a Client

Use multiple adapters in a client only if you plan to run multiple protocols or to connect to more than one network.

For information on running multiple protocols, refer to the documentation accompanying your operating system.

Before proceeding, make sure you know each adapter’s port number. To find the adapter’s port number, refer to the next

section, “Finding the Adapter’s Port Number.”

If you are running NetWare and you need to install multiple

10/100BASE-T4 PCI adapters in a client computer, follow these steps to load the NetWare ODI drivers:

1 Make sure your computer is turned off. Install the first adapter.

2 Connect the network cable to the adapter.

3 Turn on the computer, insert the EtherDisk diskette, and run the AutoLink program.

Refer to the section “AutoLink Installation” earlier in this

chapter for instructions.

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.

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:

1 In the main menu, select

Configuration/Diagnostic/

Troubleshooting and press [Enter].

Refer to Chapter 3 for instructions for accessing the main menu.

2 When the Configuration and Diagnostic screen appears, select Configuration and Diagnostic Program, and press

[Enter].

If you are testing multiple adapters, a screen displaying descriptions of each installed adapter appears. Select the adapter you want to test and press [Enter]. A screen appears, showing the selected adapter.

3 Continue with the instructions given in the next section,

“Running the Group 1 Tests.”

Group 1 tests are the default.

You can also run the tests from the command line. At the system prompt, type:

3C595CFG

Running the Group 1 Tests

To run the Group 1 tests, follow these steps:

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.

Starting the Diagnostic Program

4-5

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:

1 Select a computer to use as an echo server.

2 Insert the

EtherDisk diskette for the installed adapter in a floppy drive.

The EtherDisk diskette that accompanied the adapter contains the diagnostic program.

3 Start the diagnostic program on the echo server.

The diagnostic program that you use depends on the adapter board that is installed in the echo server. After the system prompt of the drive containing the Configuration and

Diagnostic Program, enter the name of the program (3CXXX),

as indicated in Table 4-1.

The diagnostic programs listed in Table 4-1 come on the

EtherDisk diskette that accompanies the adapter.

If any test fails, you can get additional information as follows:

1 Highlight the test that failed in the Run Tests dialog box and press [Enter].

2 Highlight the Zoom button and press [Enter].

If the diagnostic tests fail, the adapter may not be defective.

The problem may be caused by incorrect option settings, option settings that conflict with the settings of other boards, 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.

10BASE-T operation and specifications

100BASE-T specifications, including 100BASE-TX,

100BASE-T4, and 100BASE-FX

Pin assignments for the RJ-45 connector

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.

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.

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.

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.

* 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 saved may be lost.

1 Make sure the 10/100BASE-T4 PCI adapter has been properly installed in your computer.

2 Boot your computer under DOS, version 3.1 or later.

Auto Select Media Type

A utility that detects the type of network cable connected to the adapter and automatically selects that connection for packet transmission. This function is implemented by all NetWare ODI,

Windows for Workgroups, NDIS 2.01, Windows NT, and

Windows 95 drivers.

Broadcast architecture

The signaling scheme in which every node receives every broadcast from every other node at the same time.

Bus

An electronic pathway along which signals are transmitted from one area of a computer to another.

Bus master adapter

An adapter that contains its own processor, which allows the adapter to operate independently of the computer’s main processor.

CSMA/CD

Carrier Sense Multiple Access with Collision Detection.

A media-sharing scheme in which stations listen in to what is happening on the network media. If the cable is not in use, the station is permitted to transmit its message. If two or more nodes simultaneously start to transmit, a collision results. In this case each node stops transmitting for a specified interval of time, and then transmits the signal when the cable is clear.

DMI

Desktop Management Interface. The management scheme, developed by the Desktop Management Task Force (DMTF), to make management of a PC easier through standardized means of access to information from managed devices.

The standard supported by the DMI defines how information on PCs is made available and accessible.

EISA

Extended Industry Standard Architecture. The EISA 32-bit extended AT personal computer bus architecture is downward compatible with the 16-bit ISA architecture.

EMM386

Expanded Memory Manager. A dual-purpose memory manager that comes with MS-DOS. It provides access to the upper memory area, which enables you to free conventional memory by running device drivers in upper memory.

EMM386 also uses extended memory to simulate expanded memory. Refer to Microsoft documentation for additional information.

Ethernet

A local area network standard defining a physical medium and its method of placing data, or packet signaling, on a cable. Access to the cable is based on CSMA/CD (carrier sense multiple access with collision detection).

ISA

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

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 Apple

â

. 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

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.

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.
