The 1OBaseT-compatible Ethernet adapter board is designed for
IBM PS/2 and other Micro Channel-compatible computers. The
adapter connects to alocal area network (LAN) using either stan-
dard Ethernet cable or 1OBaseT twisted-pair wire with
telephone-type modular plugs.
In anetwork, the adapter will interoperate with most other
Ethernet adapters that comply with the IEEE 802.3 (10Base2,
1OBase T, and 10Base5) Ethernet standards.
Using This Manual
This user installation guide provides information on setting up
and installing the Ethernet Micro Channel adapter board for
1OBase Ttwisted-pair wiring. You can save time by reading these
instructions before installing the adapter board. Information is
provided to help you avoid some common problems such as
hardware conflicts and interconnecting cable that is incorrectly
wired. A"Troubleshooting" section is provided to help resolve
problems. Network cable information is provided in the "Network
Cable and Components" Appendix.
ii Table of Contents Introduction 1

Adapter Features
•Micro Channel-compatible.
•_10BaseT twisted-pair and AUi Ethernet network ports.
•High performance LAN controller device.
•Dual-ported 16 Kbyte random access memory (RAM) buffer.
•No direct memory access channels (DMA) required.
•On-b?ard, non-volatile memory and programmable option
selection feature replaces most jumpers to simplify
instai lati on.
•Soc_ket provided for an optional read only memory (ROM)
device. Aboot ROM may be used in this socket.
•The adapter automatically determines whether to use the
RJ-45 or AUi network connector based on which cable the
user connects. No jumper changes are required if the cable
is changed.
•"Link status" and "polarity correction" LED indicators are
provided adjacent to the twisted-pair modular network port.
When the computer power is on, the link status LED is lit if
anormal connection exists between the adapter board and
aconcentrator. The polarity correction LED is lit if the
twisted- pair wiring polarity on the receive pair is not
reversed. If the polarity is reversed, the adapter
automatically corrects the reversal and functions normally.
Driver Diskettes
The driver diskettes contain areadme.doc file, software driver
programs, and ahardware diagnostic program for this and other
LAN adapters. Refer to the readme.doc file for alisting of net-
wo?k opera?ing sy?tems that are supported by the adapter and
for mfo_rmat1on on installing the software driver programs. The di-
agnostic program on the diskettes is used to check the adapter
and network cabling when installation and configuration is 'com-
plete.
Network Environment
The adapter board is designed for use in a1OMbps 10BaseT
twisted-pair wire network environment. This type of network has
the same data throughput as a standard, coaxial-cabled,
Ethernet LAN but uses unshielded telephone-type cables. The
1OMbps twisted-pair wire network uses any 10BaseT compatible
concentrator.
The adapter board can be used to do the following:
•Set up atwisted-pair network using telephone-type wire.
•Add computers using 1OBase Ttwisted-pair cable to an
Ethernet network.
•Operate as an Ethernet LAN adapter board in astandard
Ethernet network.
Concentrators
When used with twisted-pair cable, the adapter must connect to
aconcentrator. This results in astar-wired network with the con-
centrator at the center of the star. The adapter is compatible with
10BaseT concentrators from avariety of vendors.
The adapter is also compatible with the AT&T and Hewlett
Packard "StarLAN 1O" twisted-pair signalling method. StarLAN
10 concentrators that are not 10BaseT-based are compatible
with this adapter by simply changing ajumper on the adapter.
For more information, refer to "W21 -Link Integrity Test" and
"Using StarLAN 1OConcentrators."
2Introduction Introduction 3

Installation and Setup
This section contains the information needed to configure the
adapter board and your computer system for operation. First,
verify and/or change the LAN adapter board configuration. Next,
follow the steps to prepare for the system configuration. Finally,
install the LAN adapter board and configure the system.
Adapter Board Preparation
The following paragraphs provide information on preparing the
LAN adapter board for installation. Do not install the LAN
adapter board yet.
The adapter board provides the following hardware configuration
options:
•Adevice socket: provided for installing an optional ROM,
such as aboot ROM.
•ROM size selection: 16, 32, or 64 Kbytes (jumper options.)
Factory Jumper Settings
The adapter board is preset at the factory and ready to install in
your computer. Before installing the board, verify the factory
jumper settings as shown in Figure 1. If the settings are correct
and no other hardware configuration changes are necessary, go
to the section titled "LED Indicators". If the settings do not match
the configuration shown in Figure 1or if you intend to reconfigure
the adapter board, continue on to the next section.
NOTE
Always handle the adapter board by its edges.
If you have an Ethernet 10BaseT adapter that has an additional
jumper labelled W20 "Polarity Correction'" please leave this
jumper in the factory installed on position (as labeled on the
board).

Figure 1. Factory Jumper Settings
W21 -Link Integrity Test
With this jumper (see Figure 1) removed, which is the normal set-
ting, link integrity test pulses are transmitted and received ac-
cording to the 10BaseT standard. If this jumper is installed, the
link integrity test is NOT performed (no link test pulses are gener-
ated, and received link test pulses are ignored). The twisted-pair
port (RJ-45) is enabled and the AUi port is disabled.
The adapter board will operate correctly when used in "StarLAN
1O" networks without Link Integrity such as those by AT&T and
Hewlett Packard, even though "StarLAN 1O" without Link Integrity
is not fully 10BaseT compatible. To operate the LAN adapter in
this mode, the link integrity test function must be disabled ·
Uumper installed).
LED Indicators
There are four LED indicators on the adapter bracket and
adapter as shown in Figure 2. These have the following functions:
P-Polarity Correction LED (Green)
This indicator is on when the twisted-pair received signal polarity
is correct and the link is valid (the "L" indicator is on). If this indi-
cator is off when "L" is on, the adapter will still operate properly,
but the received signal polarity is reversed.
L-Link Integrity LED (Green)
This indicator is on when the twisted-pair link is valid (10BaseT
Link Test Pass mode) or when jumper W21 (Link Integrity Test) is
installed. It indicates that the RJ-45 port is being used instead of
the AUi port.
T-Transmit LED (Yellow)
This indicator flashes to show when the adapter is transmitting.
R-Receive LED (Green)
This indicator flashes to show when the adapter is receiving. It
also flashes when transmit data from the adapter is looped back
to the receiver by the on-board twisted-pair transceiver or by an
external transceiver connected to the AUi port.

Memory Space Requirements
The adapter board can occupy as much as 80 Kbytes of com-
puter memory space with its 16 Kbytes of shared RAM buffer and
a 64 Kbyte ROM installed. Both the shared RAM and ROM de-
vice are located in the memory range C0000 to E0000 (hex).
Note that there is a maximum of 128 Kbytes of total available
RAM for all option boards installed in acomputer. This memory
space is allocated in the range C0000 to DFFFF (hex). If, for ex-
ample, two adapter boards are installed in acomputer and each
is set to use 16 Kbytes of shared RAM and each includes a 16-
Kbyte ROM device, 64 Kbytes of RAM is available for other
option boards.
When configuring the adapter board using the configuration pro-
gram on the Reference Diskette that came with your operating
system, any memory space conflict will be indicated. Anon-
conflicting value must then be specified so that the adapter will
work properly .
System Unit Configuration
Each time an option board is installed or removed, the PS/2
Micro Channel system unit must be configured using the Refer-
ence Diskette. The configuration program on the Reference
Diskette has two modes of operation: Automatic configuration
and manual configuration.
In the automatic mode, the configuration program uses the LAN
adapter board options provided on the driver diskette to automati-
cally select parameters that do not conflict with those used by
any other board installed in the system. The automatic mode is
the fastest way to configure the system. However, in some situa-
tions amanual configuration is required, such as when aboot
ROM or multiple LAN adapter boards are installed.
In the manual mode, the configuration program displays the LAN
adapter board options provided on the driver diskette and allows
you to select parameter values one at a time. If you choose a
value that conflicts with that used by another board, or avalue
previously chosen, the conflict will be noted and you must select
another parameter from alist provided by the configuration pro-
gram.
The manual mode must be used if aROM is installed on the LAN
adapter board or if multiple LAN adapters are installed. The
ROM can only be enabled using the manual mode because
"ROM disabled" is the default value used in the automatic mode.
Most network software, including NetWare, requires that each
LAN adapter board have aunique interrupt request (IRQ) chan-
nel if more than one adapter board is installed in acomputer.
The automatic mode of the Reference Diskette configuration pro-
gram, however, allows adapter boards to share IRQ channels.
No configuration conflict will be indicated when an IRQ channel is
assigned to more than one adapter board. Therefore, you must
perform amanual configuration and select unique IRQ channels
when more than one LAN adapter board is installed.
8Adapter Setup Adapter Setup 9

The configuration program allows you to change the following pa-
rameters:
•1/0 base address
•Interrupt request (IRQ) channel
•Shared RAM base address
•BIOS ROM enable, base address and size (16, 32, or 64
Kbytes)
