Connect the Network Cable
1
Connect a single network cable to the PRO/100B TX PCI adapter as
shown below. For 100BASE-TX, your network cable must be four-pair,
category 5, twisted-pair wiring. If you plan on running the adapter at 100
Mbps, it must be connected to a 100BASE-TX hub (not a 100BASE-T4
hub). For 10BASE-T, use two-pair wiring.
100BASE-TX Wiring
Twisted Pair Ethernet (TPE).
Use category 5 cable and RJ-45
connector for this adapter. Do not
use category 3 wiring. At 100
Mbps, connect to a TX hub, not a
T4 hub. For full duplex, see
instructions on page 11.

Installing Multiple Adapters
All users: The adapter’s 12-digit, hexadecimal Ethernet address is on a
sticker near the edge of the adapter. The Ethernet address is sometimes called
the node address or the MAC address. Note that the PCI slot number may not
correspond with the physical connector in your computer.
NetWare users: The server drivers use the PCI slot number to identify each
installed adapter. You can correlate the PCI slot number to the adapter by
using the Ethernet address that is printed on a label on the adapter. Run Setup
from the Intel disk to view the Ethernet address and slot number for each
installed adapter. For more information, see the README files. NetWare 4.11
server installations use unique slot numbers that are assigned during sever
setup.
Windows NT and Windows 95 users: Repeat the configuration procedure
for each adapter you want to install (add only one adapter at a time). While
PROSet can detect all the PRO/100B adapters in your computer, you still
need to perform the configuration process on each adapter. In Windows NT,
be sure to click the Show all PRO Adapters box in the Configuration window.
See the README file for more information.
Select Duplex Mode (optional)
Duplexing is a performance option that lets you choose how the adapter sends
and receives data packets over the network. The PRO/100B TX adapter can
operate at full duplex only when connected to a full duplex 10BASE-T or
100BASE-TX switching hub. To summarize:
•
Auto (requires a full duplex switching hub with auto-negotiation
capability). The adapter negotiates with the hub to send and receive
packets at the highest rate. This is the default setting. If the hub does not
provide auto-negotiation, the adapter runs at half duplex.
•
Full duplex (requires a full duplex switching hub). The adapter can
send and receive packets at the same time. This mode can increase
adapter performance capability. If the full duplex hub provides auto-
negotiation, the adapter runs at full duplex. If the full duplex hub does
not provide auto-negotiation, you need to set the adapter duplex mode
manually (see following paragraphs)
•
Half duplex. The adapter performs one operation at a time; it either
sends or receives.
NOTE:
If your hub is running at 100 Mbps and half duplex, your potential
bandwidth is higher than if you run at 10 Mbps and full duplex.
11

Manually Configuring for Full Duplex
If your switch supports auto-negotiation with the N-way standard, duplex
configuration is automatic and no action is required on your part. However,
few switches in the current installed base support auto-negotiation. Check
with your network system administrator to verify. Most installations will
require manual configuration to change to full duplex.
Configuration is specific to the driver you’re loading for your network
operating system (NOS), as shown in the following paragraphs.
To set up the duplex mode, refer to the section below that corresponds to your
operating system.
Adapter performance may suffer or your adapter may not operate
NOTE:
if your hub does not support full duplex and you configure the
adapter to full duplex. Leave the adapter on half duplex if you are
not sure what type of hub you are connected to.

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 both RJ-45 connections
(adapter and hub). If the cable is attached but the problem persists, try a
different cable. The maximum allowable distance from adapter to hub is 100
meters.
If you’re directly connecting two computers (no hub), use a crossover cable.
Most hubs require a straight-through cable, while most switches require a
crossover cable (see your hub or switch documentation to verify).
See the Cabling Information README file for more information on cross-
over cables.
Check the LED lights on the adapter.
The EtherExpress PRO/100 TX PCI adapter has three diagnostic LEDs above
the cable connector. These lights help indicate if there’s a problem with the

Make sure you’re using the correct drivers.
Make sure you’re using the drivers that come with this adapter. The driver
filename contains the letter B (for example, E100BODI.DOS). Drivers that
support previous versions of the EtherExpress PRO/100 PCI adapter do not
support this version of the adapter.
Make sure the hub port and the adapter have the same
duplex setting.
If you configured the adapter for full duplex, make sure the hub port is also
configured for full duplex. Setting the wrong duplex mode can degrade
performance, cause data loss, or result in lost connections.
Testing the adapter

Technical Information
PCI Installation Tips
PCI computers are designed to automatically configure add-in cards each time
the computer starts. Your PCI computer sets the I/O address and IRQ level for
your Intel network adapter when the computer starts. These values cannot be
changed by Intel adapter software. If you experience a problem when the
computer starts, additional configuration steps may be required.
On these computers, manual configuration is possible through the computer’s
PCI BIOS setup utility. Refer to your computer’s documentation. You may
need to verify or change some BIOS settings.
Some common PCI solutions are listed here.
•
Busmaster enabled slots. On some computers, all slots are not
busmaster enabled by default. Check your BIOS PCI bus setting. It will
set to either Busmaster or Non-busmastered. Choose Busmaster.
•
Reserve interrupts (IRQs) and/or memory addresses for ISA
adapters. This prevents PCI cards from trying to use the same settings
ISA cards are using. Check your PCI BIOS setup program. There may be
IRQ options such as ‘Enable for ISA,’ ‘Reserve for ISA,’ or ‘Disable for
PCI.’ This option is sometimes in the Plug and Play area of the BIOS
setup.
•
•
Enable the PCI slot. In some PCI computers, you must use the PCI
BIOS setup program to enable the PCI slot. This is especially common in
PCI computers with the Phoenix BIOS.
Update your PCI BIOS. An updated PCI system BIOS can correct some
PCI configuration problems. Call your computer manufacturer to see if
an updated BIOS version is available for your computer. Phone numbers
for the top PCI computer manufacturers are listed in the PCI Installation
README file on the Intel Configuration and Drivers disk.
•
Configure the slot for level-triggered interrupts. The slot the adapter
is using must be configured for level-triggered interrupts rather than
edge-triggered interrupts. Check your PCI BIOS Setup program.
Here are some example PCI BIOS setup program parameters:
PCI slot #:
Master:
Slave:
Slot where the adapter is installed
ENABLED
ENABLED
Latency timer: 40
Interrupt:
Edge-level:
Choose an IRQ from the list
Level
The exact wording of these parameters varies with different computers.

Fast Ethernet Wiring
100BASE-TX Specification: The 100BASE-TX specification supports 100
Mbps transmission over two pairs of category 5 twisted-pair Ethernet (TPE)
wiring. One pair is for transmit operations and the other for receive
operations. Segment lengths are limited to 100 meters with 100BASE-TX for
signal timing reasons. This complies with the EIA 568B wiring standard.
Fast Ethernet Hubs and Switches
The two basic types of hubs are shared hubs and switching hubs. Ether-
Express PRO/100 TX adapters can be used with either type of hub for 10
Mbps. At 100 Mbps, a TX hub or switch is required.
Shared hubs
In a shared network environment, computers are connected to hubs called
repeaters. All ports of the repeater hub share a fixed amount of bandwidth, or
data capacity. On a 100 Mbps shared hub, all nodes on the hub must share the
100 Mbps of bandwidth. As stations are added to the hub, the effective band-
width available to any individual station gets smaller. Shared hubs do not
support full duplex.
Think of a shared repeater hub as a single-lane highway that everyone shares.
As the number of vehicles on the highway increases, the traffic becomes con-
gested and transit time increases for individual cars.
On a shared hub all nodes must operate at the same speed, either 10 Mbps or
100 Mbps. Fast Ethernet repeaters provide 100 Mbps of available bandwidth,
ten times more than what’s available with a 10BASE-T repeater.
Repeaters use a well-established, uncomplicated design, making them highly
cost effective for connecting PCs within a workgroup. These are the most
common type of Ethernet hubs in the installed base.
Switching hubs
In a switched 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 switched environment, data is sent only to the port that leads to the pro-
per destination station. Network bandwidth is not shared among all stations,
and each new station added to the hub gets access to the full bandwidth of the
network.
If a new user is added to a 100 Mbps switching hub, the new station receives
its own dedicated 100 Mbps link and doesn’t impact the 100 Mbps bandwidth
of another station. Switching hubs can effectively increase the overall
bandwidth available on the network, significantly improving performance.
Switching hubs can also support full duplex.

website (see page 1).

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 provide reasonable protection against harmful interference in a
residential installation. Installed correctly, it probably will not interfere with radio 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, turn your computer on and off while the radio or TV is showing
interference. If the interference disappears when you turn the computer off and reappears when you turn the
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 covered. 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.
