Use the Correct Wiring

To reliably operate your network at 100 Mbps, you must use Twisted Pair
Ethernet (TPE) category 5 data grade wire and category 5 RJ-45 connectors
with this adapter. While ca tegory 3 or 4 wire and connectors may initially
seem to work, they will soon cause data loss. See page 18 for more
information on wiring.

For your reference, we’ve also printed the adapter’s Ethernet address on a
sticker on the back of the adapter. The Ethernet address is sometimes called
the Node address or the MAC address. Use the Ethernet address to identify
the adapter when configuring multiple adapters.

12-digit
Ethernet Address

MAC=00AA00 0B432EMAC=00AA00 0B432E

MAC=00AA00 0B432E

Use last six digits in multiple
adapter installations; see
page 7.

Always use category 5 (CAT5)
cabling when operating at 100
Mbps. Use category 3, 4, or 5 at 10
Mbps.

1 Turn off and unplug your computer. Then remove its cover.

Warning: Turn off the power before removing the computer cover.
Failure to do so could shock you and damage the adapter or
computer.

2 Remove the cover bracket from a 16-bit ISA slot.
3 Push the adapter in the slot until the adapter is seated firmly. Then,

secure the adapter bracket with the screw you removed in step 2 .

PC-3219

4 If you are installing multiple adapters, insert one adapter at a time and

then run CONFIG for each new adapter, as described in the appropriate
section on pages 5 - 11.

5 Replace the computer cover and plug in the power cord.
6 Connect a twisted-pair Ethernet (TPE) category 5 (CAT 5) cable to the

adapter. If y ou’re in a residential environment, make sure the cable is
shielded.

Configure the Adapter

Standard ISA Computers (not Plug & Play)

If you don’t have a Plug and Play computer, you need to manually configure
the PRO/100 ISA adapter. On most computers, CONFIG.EXE will try to
assign an available interrupt and I/O address to the adapter. However, you
may need to change the assigned values if your computer will not boot or run
properly following the configuration process.

The next step in the process depends on your operating system and network
type. Windo ws 3.1 and Windows NT users configure and test the adapter
before starting the operating system. Windows 95 users start the operating
system Windows 95 first and then configure and test the adapter. Choose your
operating system and proceed as shown here:

• DOS, Windows 3.1, NetWare users: go to pa ge 5

• Windows NT users: go to page 8

• Windows 95 users: go to page 10

• All others: go to page 12

Plug and Play computers

Plug and Play computers automatically detect and configure add-in boards.
You do not have to run the Intel CONFIG utility to configure the Intel
EtherExpress PRO/100 ISA adapter if your computer is Plug and Play.
However, you may need to configure your computer’s CMOS setup utility to
allocate an IRQ and I/O address for the adapter. For more information about
Plug and Play resources, read your computer user’s guide.

To start the automatic configuration, turn your computer on. It automatically
configures the PRO/100 ISA adapter while it boots. Configuration is complete
when the DOS prompt appears.

The next step in the process depends on your operating system and network
type:

• DOS, Windows 3.1, NetWare* users: go to pa ge 5

• Windows NT users: go to page 8

• Windows 95 users: go to page 10

• All others: go to page 12

your computer. Choose the next ste p accordingly.
For Plug and Play computers, run Express and exit CONFIG. If you

want to check adapter IRQ and I/O address settings, click Custom after
Express is done.

For non-Plug and Play computers, run Express and exit CONFIG. If
your computer locks-up after installing the adapter and running Express,
you may need to manually configur e the adapter. Follow the instructions
in the Custom Config section below.

If you want to test the adapter with another PRO/100 ISA adapter on the
network (ping-pong test), see the Test procedure on the next page before
continuing.

CONFIG runs a series of diagnostic tests that makes sure the adapter and
network are functioning prop e rly. If CONFIG finds a problem, it displays
the results and some possible solutions.

If you put more than one Intel PRO/100 ISA adapter in your computer,
click the Custom button on the bottom of the screen. A separate window
for each installed adapter appears.

Test the adapter with a responder on the network (optional)

CONFIG can test the network more thoroughly if you run a Ping-Pong test.
1 Go to another computer on the network that has a PRO/100 ISA adapter

installed. (The other adapter must be the same model. For example, the
test will not work with a PRO/100 PCI adapter.)

2 Run the CONFIG utility and select Custom. From there, choose

Diagnostics from the menu bar and then Ping-Pong. Set this adapter up
as a Slave.

3 Return to the first computer and use CONFIG to set it up as a Master.
4 In the panel that appears, enter the number of repetitions you want to run

(such as 1000). Click OK to start the test.

5 When the test finishes, the pass or fail results appear. Click OK on both

computers to return to the main window.

Duplex Mode and Speed
Selection

Duplexing is a performance option that lets you choose how the adapter sends
and receives packets over the network. The speed setting refers to either 10 or
100 Mbps. Running the adapter at full duplex requires a full duplex switch.

In its default mode, the PRO/100 ISA adapter automatically senses the speed
and duplex mode of your network. If you want to run in full duplex mode and
you have a switch that doesn’t support auto-negotiation, you’l l need to
manually configure for full duplex. If you are installing the PRO/100 ISA
adapter in a NetWare server, refer to the README files for complete
configuration information.

Manually configuring duplex mode and speed

To manually set duplex mode and speed, use the MEDIATYPE keyword. For
Windows 95 and NT, you can select the keyword from within the operating
system. For NetWare drivers, you’ll need to edit the NET.CFG file. The
following steps summarize each method. See the README files for complete
information.

Troubleshooting

If the adapter can’t connect to the network

Make sure the cable is installed properly

The network cable must be securely attached at all connections. If the cable is
attached but the problem persists, try a different cable.

If you’re operating at 100 Mbps, you must use TPE category 5 wiring. See
the 100 Mbps Cabling Specifications README file for a list of recommen­ded cables and information on how to install the cabling properly.

If you’re directly connecting two workstations (no hub), you can use a
crossover cable. See the 100 Mbps Cabling Specifications README file for
information on crossover cables.

Check the LED lights on the adapter

The PRO/100 ISA adapter has three diagnostic LEDs below the cable
connector. These lights indicate if there’s a pr oblem with the connector,

Common problems and possible solutions

I’m using a Plug and Play computer and need to change the I/O address or
interrupt values of the PRO/100 ISA adapter.

• Manually override the automatic configuration values by running CONFIG
and clicking Custom. Click the Lock Resources and Activate box to change
values. Save the configuration before exiting.

While starting, my computer reports a resource conflict.

• Run Express CONFIG and restart your computer.

The Ethernet address is ‘unknown’ when I select Custom Config.

• This is normal on some computers. After making your IRQ and I/O address
settings, save your configuration file. Go back to the main CONFIG window
and click Custom again. Ethernet address now displays.

In multi-adapter computers, the adapters fail to keep their I/O and address
settings.

• Run CONFIG and choose Custom. For each installed adapter, click the Lock
Resources and Activate box. Set the IRQ and I/O addresses again if necessary.
Save the settings before exiting.

Diagnostics pass, but the connection fails.

• Make sure the network cable is securely attached.

• Make sure you’re using category 5 cabling/connectors when operating at
100 Mbps.

• Check duplex setting for possible mis-match.

Link LED does not light.

• Check all connections at the adapter and hub.

• Make sure speed and duplex modes are correct for hub. See page 13 for details.

Activity LED does not light.

• Make sure you’ve loaded the network drivers.

• The network may be idle; try sending data from this workstation.

• Try another cable.

• The adapter isn’t transmitting or receiving data; tr y another adapter.

Data is corrupted or sporadic.

• Make sure you’re using category 5 cabling/connectors when operating at
100 Mbps.

• Try another port on the hub and/or another cable.

The adapter stopped working after adding a second adapter.

• Run CONFIG to check for conflicting interrupts or I/O addresses.

• Try reseating the adapter.

• For multiple adapters, add serial parameter for each adapter. See page 7.

The adapter stopped working without apparent cause.

• Try reseating the adapter or try a different slot.

• The network driver files may be corrupt or deleted. Reinstall the drivers.

• Try a different PRO/100 ISA adapter.

Technical information

Fast Ethernet Wiring

100BASE-TX Specification: The 100BASE-TX specification supports
100 Mbps transmission over two pairs of twisted pair Ethernet (TPE) wiring.
In two-pair wiring, one pair of wires is used for transmission, and the second
is used for collision detection and receive.

Because a 125 MHz frequency is used on the wire, 100BASE-TX calls for
category 5 (CAT 5) wiring. Segment lengths are limited to 100 meters with
100BASE-TX for signal timing reasons.

Refer to the 100 Mbps Cabling Information README file for more informa­tion.

Fast Ethernet hubs

New hubs and switches, such as Intel’s Express 100BASE-T Fast Ethernet
Stakable Hub and Express 100BASE-TX Switching Hub, are becoming
available to support a variety of configurations. These hubs are divided into
two basic types: shared and switching. You can use EtherExpress PRO/100
adapters with either a hub or a switch for 10 Mbps or 100 Mbps operation.
For the latest information on Intel hubs and switches, visit our website at
http://www.intel.com.

18

Shared hubs (also called repeaters or concentrators)

In a shared hub network environment, computers are connected to hubs. All
ports share a fixed amount of bandwidth, or data capacity. A 100 Mbps hub
means that all nodes on the hub must share the 100 Mbps of bandwidth. As
stations are added to the hub, the effective bandwidth available to any indi­vidual station gets smaller. With an Intel Stackable hub, all ports in the entire
stack share the 100 Mbps of bandwidth.

Think of this hub as a single-lane highway that everyone shares. As the num­ber of vehicles on the highway increases, the traffic becomes cong ested and
transit time for individual cars increases.

On the shared hub, all nodes must operate at the same speed, either 10 Mbps
or 100 Mbps. Fast Ethernet hubs provide 100 Mbps of available bandwidth,
ten times more than what’s available with a 10BASE-T hub.

Hubs, such as Intel’s, use a well-established, uncomplicated design, making
them highly cost-effective for connecting computers within a workgroup.
Shared hubs are the most common type of Ethernet hubs in the installed
base.

Switching hubs (switches)

In a switching hub network environment, each port gets a fixed, dedicated
amount of bandwidth. In the highway scenario, each car has its own lane on a
multi-lane highway and there is no sharing.

In a switching hub environment, data is sent only to the port which leads to
the proper destination station. Network bandwidth is not shared among all sta­tions and each new station added to the switching hub gets access to the full
bandwidth of the network.

If a new user is added to a 100 Mbps switching hub, the new computer re­ceives its own dedicated 100 Mbps link and doesn’t impact the 100 Mbps
bandwidth of other users. Switching hubs can effectively increase the overall
bandwidth available on the network, significantly improving performance.

Adapter Configuration Notes

Manual configuration

If you install your new PRO/100 ISA in a non-Plug and Play computer you
can manually assign an I/O Address and IRQ to the adapter using Custom
Config in the CONFIG program. Check the “Lock Resources and Activate”
box to choose an available IRQ and address. When done, save the configura­tion before exiting the CONFIG program.

Moving the adapter to another computer

If you move a PRO/100 ISA adapter from a non-Plug and Play computer to a
Plug and Play one, you must run the CONFIG program again and follow the
instructions exactly. The CONFIG program first deactivates the Lock Re­sources feature. Then it prompts you to restart your computer. When the com­puter starts again, the Plug and Play resources are properly assigned to the
PRO/100 ISA adapter.

Adapter defaults

The PRO/100 ISA adapter default settings for speed and duplex mode are
“Automatic.” However, when attaching to a device that is not auto-negotiat­ing, the defaults are half duplex and 10 Mbps. To manually change speed or
duplex settings, use the driver keywords for your operating system. See page
13 for details.

Overriding adapter settings

On some networks you may need to override or specifically identify the speed
and duplex settings on the PRO/100 ISA adapter. All network drivers allow
you to do this with the MEDIATYPE keyword. Refer to page 14.

FCC Compliance Statement

This product has been tested and found to comply with the limits for a Class B computing device pursuant to Part
15 of the FCC rules. These limits are designed to pr ovide reasonable protection against harmful interference in a
residential installation. Installed correctly, it probably will not interfere with r adio or TV reception. However we do
not guarantee the absence of interference.

This product generates and uses energy of about the same frequency as radio and TV broadcasts. Installed
incorrectly, it may interfere with reception of radio and TV broadcasts.

If you suspect this product is causing interference, t u rn your computer on and off while the radio or TV is showing
interference. If the interference disappears when you turn the computer off and reappear s when you tur n t he
computer on, something in the computer is causing interference.

To reduce interference, try these suggestions:

• Change the direction of the radio or TV antenna.

• Move the computer, radio or TV. For example, if the computer is to the right of the TV, move it to the left of the
TV. Or move them farther apart.

• Plug the computer into a different electrical outlet than the radio or TV.

• Ensure that all expansion slots (on the back or side of the computer) are co vered. Also ensure that all metal
retaining brackets are tightly attached to the computer.

NOTE
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This

device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
