FCC Warning
-----------
The SN2000PT and SN2000PCT have been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference when these devices are operated in a commercial environment.
These devices generate, use and can radiate radio frequency energy and,
if not installed and used in accordance with this installation manual, may
cause harmful interference to radio communications. Operation of these
devices in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his
own expense.

1. Introduction
---------------
This section is an introduction of the SN2000P series. It provides an
overview of the adapters, a brief description of their features, and
information on their LED indicators.
1.1 Overview
The SN2000P series consists of 16-bit Ethernet adapters that comply
with the Plug-n-Play (PnP) specifications. The series provides
installation flexibility with its ability to connect on both PnP
and non-PnP systems. On PnP systems, the adapters are automatically
configured without user intervention, while on non-PnP systems,
configuration is manually done through a setup program.
The series,which can be used with the IBM PC, PC XT, PC AT and their
compatibles, includes the following models:
SN2000PCT
This model allows connection to a thin coaxial cable or
10BASE-T twisted-pair segment through its BNC and RJ-45 ports,
respectively. Only one port, however, may be used at a time.
SN2000PT
This model works with 10BASE-T twisted-pair cable. It provides
one RJ-45 connector.
1.2 Features
The SN2000P series complies with the IEEE 802.3 Ethernet standards
and uses VLSI components for enhanced reliability. The following
are just a few of the series' distinctive features.
Easy installation
The series complies with PnP specifications, thus configuration
on PnP systems is handled entirely by the system with no user
intervention. While on non-PnP systems, configuration is
accomplished through an innovative setup program included in the
SN2000P package. In either case, assignment of system resources
is handled through software instead of physical jumpers. Once the
adapter is inserted into a slot in your computer, you do not need
to remove it to change its settings.
Support for 8-bit and 16-bit expansion slots.The series can be used
in 8-bit (the short XT-style) or 16-bit (AT-style) expansion slots.
The adapter automatically detects the type of slot being used.
Use of NE-2000 drivers. The series can use the same network drivers
as the Novell NE-2000 cards.
Setup/diagnostic program and LEDs. The series comes with a
setup/diagnostic program that tests all adapter functions to verify
correct operation of the card. The two LED indicators on the
adapter report network activity.
Support for remote boot function. The series can be used on PCs or
diskless workstations for remote booting on the network. In order
to use the remote boot function, however, a remote boot ROM
(purchased separately) must be installed on the card.
Runs a wide variety of networking software. The series can be used
with all popular networking software. The table below lists the
supported software:
NDIS driver
Novell NetWare 3.x and 4.x ODI driver
MS LAN Manager
Packet driver
Win/TCP Pathway Access for DOS

IBM LAN Server
3COM 3+Share
DECnet PathWork
Banyan VINES
Windows for Workgroups
3COM 3+Open
Windows NT
Windows 95
Windows NT Advanced Server
SCO UNIX
1.3 LED Indicators
The LEDs on the SN2000P series adapter provide information on the
state of the network. The LEDs work in different ways, depending on
the type of Ethernet cable being used. The LEDs and their functions
are listed below.
ACT Indicator. Indicates power and/or data transmit/receive.
LINK Indicator. Indicates the state of the data link.

2 Installation
-------------------------------------------------
2.1 Inserting the Adapter into the PC
CAUTION: To prevent damage to the adapter during installation,
touch a grounded object to release any electrostatic build up
in your body. Static electricity can damage certain components
on the adapter.
To insert the adapter into your computer, follow these steps:
Turn OFF your PC and unplug it from the power outlet.
Remove the PC cover.
Insert the adapter into an available ISA expansion slot.
The SN2000P series adapter can be used in a 8-bit or a
16-bit expansion slot. Use of a 16-bit slot is
recommended for better network performance.
Secure the adapter in the slot with a bracket screw.
Replace the computer cover.
After inserting the adapter into your computer, you will no
longer need to remove it to adjust physical settings when
configuring the card. Configuration (that is, assigning system
resources to the adapter) takes place entirely through software.
2.2 Connecting Network Cables
2.2.1 Connecting 10BASE-T Twisted-Pair Cable
This type of connection requires a twisted-pair cable of
maximum length of 100 meters with RJ-45 connectors at both ends.
Pins 1 and 2 of this cable must be a pair and so should pins 3 and 6.
Each pin must connect straight to the other end of the cable (that
is, pin 1 to 1, 2 to 2, 3 to 3 and 6 to 6).
Connect one end of the twisted-pair cable to the RJ-45 port of the
adapter and the other end to a 10BASE-T hub. To connect, orient the
RJ-45 connector correctly with the port, then push the connector into
the port until it locks into place.
2.2.2 Connecting 10BASE2 Thin Coaxial Cable
This section discusses how to connect the SN2000PCT to a 10BASE2
Ethernet network. Follow these steps:
Turn OFF the computer.
Connect a BNC T-connector to the BNC port on the adapter.
If your computer exists at the end of a 10BASE2 segment,
then you only need to connect a single cable to the adapter
via the T-connector; otherwise, you will need to connect two
cables to both ends of the T-connector. With just a single
cable connected to the T-connector, you will need to attach
a terminator on the unused end of the T-connector.
2.3 Configuring the Adapter
How the SN2000P series adapter is configured depends on the type
of system into which it is installed. In PnP systems with both
PnP system BIOS and a PnP-compliant operating system, the adapter
configuration is handled entirely by the computer. All you need
to do is insert the card into an ISA slot in your computer, secure
the card, close the case and connect the network cable. The adapter
along with the other installed PnP cards will be configured by the
BIOS and the operating system at system bootup. After booting up,
just load the appropriate drivers to establish the software
connection to your network. If your computer connects to a network
during bootup (via startup files), then this step is handled by the
system.
On non-PnP systems, the series operates as an ordinary ISA-bus adapter
without the PnP function. To configure the adapter in such an
environment, run the provided setup program to assign system resources
for the card.
2.4 Testing the Adapter Functionality
The setup/diagnostic program incorporates two diagnostic tests for
checking the adapter's basic functions and connectivity on the network.
These tests can be used on both PnP and non-PnP systems.
The Network Diagnostics test checks the adapter's ability to
communicate on the network. This test requires that at least two
computers be connected by an Ethernet cable. One computer should be
set as the Responder and the others as an Initiator. If this test
succeeds, then you have confirmed that the adapter can communicate on
your network.
For the Network Diagnostics to be successful,network drivers supplied
on the SN2000P series' installation diskette must be located in the
same directory as the setup program. The install program on the
diskette takes care of copying all necessary files from the
installation diskette to the same directory on your hard drive.Unless
you move files at a later time,you should not have any problems here.
If either the Adapter Basic Diagnostics or the Network Diagnostics
fail, then you need to change something on your configuration.
On non-PnP systems, first try to verify that the base address and
the interrupt number do not conflict with other cards. PnP systems
should properly handle this aspect of configuration. If you still
have a problem on a PnP computer system,the trouble is most likely
the network drivers, not the base address or the interrupt number.
