CHAPTER 1
INTRODUCTION
This manual provides installation and reference information for
the network adapters. The network adapters connect your PC to: a
10BASE-T twisted pair Ethernet network segment, a thin Ethernet
10BASE-2 coaxial network, a fiber optic network segment, or a
transceiver via an AUI cable.
The adapters incorporate Cabletron Systems’ LANVIEW
LEDs.
These diagnostic LEDs indicate power, network transmit and
receive, link established, and collision present conditions as soon
as the adapter is connected to the network segment.
1.1 USING THIS MANUAL
This manual is organized so that you can follow sequential
chapters as you install the adapter. Read Chapter 1 first to
familiarize yourself with the adapter’s capabilities. Then:
• Copy the software diskettes supplied with the adapter.
• Install the adapters as outlined in Chapter 2.
• Run the diagnostic program supplied with the adapter.
• Connect the adapter to the network as outlined in Chapter 3.
• Install the network drivers required for your application as
outlined in the Network Software Installation Guide.
Chapter 1, Introduction, discusses the capabilities of the adapters.
Chapter 2, Installation, provides instructions for installing the
adapters in your computer.
Chapter 3, Making Network Connections, provides instructions
and requirements for connecting your adapters to the network.
Page 1-1
INTRODUCTION
1.2 THE ADAPTER FEATURES
The following sections outline the features of the adapters.
1.2.1 Connectivity
The Cabletron Systems adapters connect your computer to an
IEEE 802.3 Ethernet network. The various adapter models
incorporate either an Ethernet 10BASE-T twisted pair port, a thin
Ethernet coaxial BNC port, an SMT type fiber optic port, or an
external transceiver via an AUI cable. All port types provide
access for SNMP network management such as Cabletron’s
SPECTRUM
, Remote LANVIEW/Windows, or any SNMP-
compliant management software.
1.2.2 Thin Ethernet Port
The adapter’s 10BASE-2 port provides a thin Ethernet BNC
connection to a coaxial segment such as the backbone of a
corporate-wide network, or to a concentrator such as Cabletron’s
MMAC Multi Media Access Center
.
1.2.3 10BASE-T Twisted Pair Port
The adapter’s 10BASE-T twisted pair port employs the RJ-45
eight-pin industry standard connector which must be connected
to a concentrator such as Cabletron’s MMAC Multi Media Access
Center. The 10BASE-T twisted pair port on the adapter has builtin automatic polarity detection and correction. This means that if
the cable connected to the twisted pair port should have the RX+
and RX– leads reversed, the port circuitry will automatically
detect and correct this problem.
When polarity correction has occurred, the link LED flashes to
indicate that this automatic correction has been performed.
Performance will not be impacted.
Page 1-2
INTRODUCTION
1.2.4 Fiber Optic Ports
The fiber optic ports on the adapter employs two ST type fiber
optic connectors. The dark gray ST connector is the fiber optic
receive port and light gray ST connector is the fiber optic transmit
port. The ST connector fiber optic ports can utilize
50/125 µm, 62.5/125 µm, and 100/140 µm fiber optic cables.
1.2.5 Jabber Protection
A built-in jabber protection scheme ensures that the network is
not disabled due to the transmission of excessively long packets
(jabber). This protection scheme automatically interrupts the port
for 96 bit times (1 bit time = 100 ns.) if the port has been
transmitting continuously for more than 65,536 bit times.
1.2.6 LANVIEW LEDs
Cabletron Systems’ adapters incorporate Cabletron Systems’
LANVIEW Status Monitoring and Diagnostic System. The
LANVIEW LEDs help you diagnose problems, such as failure to
establish a twisted pair link between the adapter and an Ethernet
device at the far end of the link. Individual LEDs advise you when
the adapter is receiving or transmitting data packets, or when a
collision condition exists on the network (see Figure 1-1).
• Media Link Good (LNK) LED fiber optic adapters
When lit, this green LED indicates that a link has been established
between the fiber optic port on the adapter and the fiber optic
device at the other end of the fiber optic link segment. This LED
remains lit as long as the link is maintained.
• Link OK (LNK) 10BASE-T only
When lit, this LED indicates that a link has been established
between the adapter and the device at the other end of the
Ethernet segment (green indicator).

• Collision Present (CLN)
This LED flashes when the adapter is transmitting to indicate that
the adapter is detecting a collision condition on the network (red
indicator).
• Receive (RCV) network traffic
This LED flashes to indicate that the adapter is receiving data
packets from the network (yellow indicator).
• Transmit (XMT)
This LED flashes to indicate the adapter is transmitting packets
onto the network (green indicator).

INTRODUCTION
1.2.7 Software
Software drivers, related software, and diagnostics are supplied
by Cabletron Systems on floppy diskettes shipped with the
adapter. The drivers support a variety of network platforms. Refer
to the Network Software Installation Guide.
The diagnostic program provided with the adapter allows you to
check the adapter’s operation at various levels, through a series of
tests. The diagnostic program allows you to detect where a
problem might be located in the operation of the adapter, or
determine if a problem exists in the communication between the
adapter and the computer.
1.2.8 Statistics
Statistics can be gathered from the adapter either from your
computer, or from another workstation utilizing Cabletron
Systems’ SPECTRUM, Remote LANVIEW/Windows, Remote
LANVIEW for SunNet Manager
, or other SNMP-compliant
network management software. Through this software, you can
gather statistics on the adapter’s activity on the Ethernet network.
For further information on Local Statistics, refer to the Network
Software Installation Guide.

2.2 THE E1100/E2100 SERIES ADAPTERS
This chapter shows you how to prepare an E1100 or E2100 Series
Cabletron Systems’ network adapter and install it in your
computer. The I/O base address and Boot PROM address are
hardware configurable for the E1100 and E2100 Series adapters,
while the other parameters are set through software. The
preparation and installation procedure for the adapter consists of
the following steps:
• Unpacking the adapter and software
• Making a backup copy of the software
• Configuring and installing the adapter
• Running diagnostics
• Making network connections
• Installing network drivers
Page 2-2
INSTALLATION
2.2.1 Unpacking the Adapter
The network adapter and its software are shipped separately. The
complete installation package should contain one conductive
pouch with the adapter and this manual. The software is shipped
in a shrink-wrapped package containing the software, a license
agreement, and a Network Software Installation Guide.
Carefully remove the conductive pouch from the box. Leave the
adapter in the conductive pouch until you are ready to install it.
Open the shrink-wrapped software package when you are ready
to install the software. Be sure to read the license agreement.
CAUTION: The adapter is sensitive to static discharges. Hold it by the
corners. Avoid contact with the PC bus edge connector or any of the
components, except the jumpers. Failure to observe all static precautions
can result in damage to the adapter.
2.2.2 Copying the Software
Before you begin the installation, it is important that you make a
backup copy of the Cabletron software supplied with the adapter.
Use the disk copy routine for your PC to make a duplicate copy of
the Cabletron software diskettes. Store the original software in a
safe place, and use the copies for the actual installation procedure.
2.2.3 Preparing the E1100 for Installation
The E11xx Series employs a socket for an optional Boot PROM. All
parameters except the I/O base address and PROM base address
are set through software. Instructions are included for setting the
I/O base address, and installing the Boot PROM. Figure 2-1, an
E1112 adapter, shows the locations of the jumpers and Boot
PROM socket. Boot PROM addressing is covered in the
installation instructions included with the Boot PROM.
