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

802.5 Token-Ring network. The various adapter models
incorporate both an unshielded (RJ-45 UTP) twisted pair port, and
a DB-9 shielded twisted pair port. 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 RJ-45 Unshielded Twisted Pair Port

The adapter’s unshielded twisted pair port employs the RJ-45
eight-pin industry standard connector. The adapters do not require
a media filter for attachment of a UTP lobe link. An unshielded
twisted pair lobe cable can be connected directly to this port. The
other end of this lobe cable must be connected to an IEEE 802.5
compliant Token-Ring device such as one of Cabletron’s TRMIM
Token-Ring Media Interface Modules.

1.2.3 DB-9 Shielded Twisted Pair Port

The adapter’s shielded twisted pair port incorporates the industry
standard DB-9 connector. A shielded pair lobe cable can be
connected to the DB-9 port. The other end of the lobe cable must be
connected to an IEEE 802.5 compliant Token-Ring device such as
one of Cabletron’s TRMIM Token-Ring Media Interface Modules.

Page 1 - 2

INTRODUCTION

1.2.4 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 a device at
the far end of the link. Individual LEDs advise you when the
adapter is sending and receiving data packets, when wire faults
occur in the lobe link, and the operating speed of histogen-Ring. A
more detailed description of the functions of the individual LEDs
appears in Chapter 2,

Installation

.

1.2.5 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. For network
software installation instructions, refer to the Network Software
Installation Guide that accompanies the software.

The diagnostic program provided with the adapter is user-friendly
and menu-driven and does not require detailed instructions. With
the diagnostic program you can check the adapter’s operation at
various levels, through a series of tests. The diagnostic program
detects where problems might be located in the operation of the
adapter, or determines if a problem exists in the communication
between the adapter and the computer.

1.2.6 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

style bus.

2.2 PREPARING THE ADAPTERS

This chapter shows you how to prepare a Cabletron Systems
Token-Ring network adapter and install it in your computer. The
clock configuration for both the T2015 and T3015 is set through a
jumper. The I/O address for the T2015 is set through a dual DIP
switch, and the I/O address of the T3015 is set by configuring the
Adapter Description File for your microchannel-compatible
computer. All other parameters for both adapters are set through
software. The preparation and installation procedure for any of the
adapters consists of:

• Unpacking the adapter and software, and making a backup

copy of the software.

• Configuring and installing the adapter, and running

diagnostics if necessary.

• Making network connections, and installing network drivers

for your operating system.

Page 2 - 1

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

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.

The adapter is sensitive to static discharges. Hold it by the

CAUTION:

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.

Network Software Installation Guide

.

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.

2.3 PREPARING THE T2015 ADAPTER

Before you install the T2015 Token-Ring adapter in your computer,
you will have to set the adapter’s I/O base address, and possibly
the adapter’s Clock Source.

The I/O base address is set through a pair of dip switches. If your
T2015 adapter is being installed in a computer that requires a
synchronous clock source for its adapter boards, you will also need
to change the clock source jumper.

Page 2 - 2

INSTALLATION

Setting this jumper is described in Section 2.3.2. The jumper’s
default setting is correct for most computers. Refer to Figure 2-1 for
the jumper and switch locations.

If your adapter is installed in a computer with incompatibilities

NOTE:

in the bus architecture, such as an IBM PS/2 Model 30-286,
you may need to change the bus compatibility switch in the
driver software command line. Setting this switch is described
in the Network Software Installation Guide.

2.3.1 Setting the I/O Base Address

Before the T2015 adapter can be used, the I/O base address must
be set using a pair of two-position dip switches accessible through
the card’s bracket. The switches are located just below the ports on
the bracket (see Figure 2-2).

The card’s other parameters are set during the installation of
network software. This configuration is discussed in the Network
Software Installation Manual.

The I/O base address is a hexadecimal field that distinguishes the
T2015 adapter from other adapters that may be in the PC. The
adapter must be set to one of four base addresses - 0A20, 0A80,
1A20, or 1A80.

The adapter is sensitive to static discharges. Hold the
adapter by its corners. Avoid contact with the PC bus edge

The I/O base address can be reset after the adapter has been
installed. However, the new I/O base address must be entered into
your network driver’s configuration. Note that only two base
addresses, 0A20 and 1A20, can be used if you are running IBM’s
PC LAN Program or other NetBIOS-based applications. Refer to
the

Network Software Installation Guide

for more information.

If an incompatibility exists in the clock source, and you need to set
the adapter for the synchronous clock source mode, proceed to
Section 2.3.2 which follows. If you are installing the adapter in any
other AT-compatible machine, proceed to Section 2.4 to begin
installation procedures.

Page 2 - 5

INSTALLATION

2.3.2 Setting the Clock Source Jumper

You will need to set the Clock Source Jumper (JP1) if your PC
requires the adapter to be synchronous with the system bus clock.
In most computers, the adapter will use its own clock source,
meaning that the adapter is running in the asynchronous mode. If
the adapter uses the system’s clock source, it will be running in the
synchronous mode.

JP1 is used to select which source clock will be used, the adapter’s
or the system’s. For most AT-compatibles, you will not have to
change this jumper.

To set the jumper, place shunts as shown in Figure 2-3, below:

When you have completed setting the Clock Source Jumper, you
are now ready to install the T2015 into your computer.

2.4 INSTALLING THE T2015 ADAPTER

A T2015 adapter can occupy any 16-bit expansion slot or an XT
type slot, but in an 8-bit slot, performance will be degraded.
Follow these steps to install the T2015 adapter in your computer:

• Turn off the power to the PC and peripherals and disconnect
all power cords and cables.

Page 2 - 6

INSTALLATION

• Follow the instructions in your computer user manual, and

using static discharge precautions, remove the cover from the

• Remove the backplate from the selected slot by removing the

screw holding the backplate in place, and slide the backplate
out of the slot.

Figure 2-4. Installing the T2015 Adapter

Carefully insert the adapter into the expansion slot as shown in
Figure 2-4. Orient the adapter so the PC edge bus connector is
pointed down and the ports face out the back of the PC. Align the
adapter so the PC bus edge connector is lined up with the
expansion slot, and firmly press the adapter into the slot.

Reinsert the screw removed in disassembly and replace the PC
cover. Reattach the power and peripheral cables and turn on the
power for the PC and the peripherals.

2.10 TROUBLESHOOTING CHECKLIST FOR ADAPTERS

• Make sure the adapter is installed and properly seated in the

PC chassis connector.

• On the adapter, if the coax port is used it is necessary to have a

Tee and terminator attached to it.

• If the adapter does not initialize, verify that the bus slot is

operational by swapping the adapter with an adapter that you
know is functioning.

• Try swapping the adapter with a known working adapter.

• The interrupt, I/O address or memory parameters could be

conflicting with another adapter. Use a program like “Check­It” to determine what settings are currently in use by other
adapters.

• Verify that the cable is attached to the media port that you want

to use, and that the cable is actually a Token-Ring twisted pair
cable.

• If a connection to a server or another host cannot be

maintained, check the cable first with a TDR or pair scanner.
After verifying the cable, check the device that you are trying
to communicate with. Verify that you can ping it or that other
clients can contact it.

2.11.1 Diagnostics

Diagnostics are included in the Cabletron software diskette under
the directory DIAGS. These diagnostics are menu driven and can
be run from the floppy diskette, or copied onto your hard disk into
the directory containing the Cabletron software.

2.11.2 Software Tips

The following tips may help you avoid software related problems:

• Cabletron supplies different drivers for use with different
operating systems. Make sure that you are using the correct
driver and that the I/O hardware switch setting agrees with
the software I/O setting that you selected.

• If you are using Novell NetWare, Cabletron supplies a direct
IPX and a packet driver IPX. Make sure you are using the
correct IPX.COM file. See the Network Software Installation
Guide included with the Cabletron software for more
information.

• When using the packet driver version 4.0 or above, you must
use IPX (NSHPD) LAN Option 1.05.03 or above.

• If you are using a Kingston Memory Board, DO NOT use
automatic configuration after copying the Cabletron ADF file.

CHAPTER 3

NETWORK CONNECTIONS

The network connections for all Cabletron Systems Token-Ring
adapters are the same. An adapter can be connected to the network
through either the adapter’s DB-9 shielded twisted pair port or
RJ-45 port. The port should have been selected during installation
procedures. Refer to the appropriate installation chapter for your
model adapter for further information on selecting a port.

3.1 CONNECTING TO AN STP CABLE

The Token-Ring adapter can be connected to a shielded twisted
pair lobe link through the DB-9 port. The shielded twisted pair
connection consists of two twisted pairs:

• One pair (RX+, RX-) for the incoming (receive) signal from the

upstream neighbor in the Token-Ring.

• One pair (TX+, TX-) for the outgoing (transmit) signal to the

downstream neighbor in the Token-Ring.

The T2015 Token-Ring adapter (Figure 3-1) is used here for a
connection example. To connect the adapter to a Token-Ring lobe
link via the DB-9 port:

• Connect the DB-9 connector (2, Fig. 3-1) on the end of the lobe

link to the DB-9 port (1).

• Tighten the screws (3) to secure the connector to the port.

Once the PC is powered up and on the network, check the
condition of the bicolor LED. The bicolor LED will be off when the
PC is first powered up. The LED will turn green when the adapter
has accessed the network. If the bicolor LED turns red, there is a
wire fault present. See Section 1.6, LANVIEW LEDs, for more
information.

If the bicolor LED is not lit or remains red, check the following
items:

• Verify that the PC is powered up.

• Check that the device at the other end of the lobe link is
properly connected.

• Verify that the DB-9 connector on the lobe link has the proper
pin-outs (see Section 3.3).

• Check the cable for continuity, and ensure that the cable is a
twisted pair Token-Ring cable.

• Check that the adapter is properly seated in the expansion slot.

• Check that the twisted pair connection meets dB loss and cable
specifications outlined in Section 3.3.

If the bicolor LED is still not lit, or is red, call Cabletron Systems
Technical Support.

3.2.4 Connecting to a UTP Cable

The Token-Ring adapter can be connected to an unshielded
twisted pair lobe link through the RJ-45 port. The unshielded
twisted pair connection consists of two twisted pairs:

• One pair (RX+, RX-) for the incoming (receive) signal from the

upstream neighbor in the Token-Ring.

• One pair (TX+, TX-) for the outgoing (transmit) signal to the

downstream neighbor in the Token-Ring.

To connect the adapter to a Token-Ring lobe link, via the RJ-45
port, connect the UTP lobe link (4, Fig. 3-3) to the adapter by
inserting the RJ-45 connector (3) into the RJ-45 port (2) on the
adapter.

LED (1) is lit. The LED will be off when the PC is first powered up.
The LED will turn green when the adapter has accessed the
network.

Page 3 - 5

NETWORK CONNECTIONS

If the bicolor LED remains unlit or turns red, check the following
items:

• Verify that the PC is powered up.

• Check that the device at the end of the lobe link is properly
connected.

• Verify that the RJ-45 connector on the lobe link has the proper
pin-outs (see Section 3.3).

• Check the cable for continuity, and ensure that the cable is
actually a twisted pair cable.

• Check that the adapter is properly seated in the expansion slot.

• Check that the twisted pair connection meets dB loss and cable
specifications outlined in Section 3.3.

The Token-Ring adapter is now ready for operation. If you
encounter any problems, contact Cabletron Systems Technical
Support.

3.3 NETWORK SPECIFICATIONS

This section outlines the Token-Ring Network operating and
environmental specifications.

3.3.1 Cable Specifications

Each Token Ring adapter supports IBM shielded twisted pair (STP)
cable Types 1, 2, 6, 8, and 9. The adapters also support voice grade,
unshielded twisted pair cable (IBM Type 3).

• Type 1 - Two shielded twisted pairs (STP) of 22 AWG solid wire
for data. Typically used for the longest cable runs in walls of
buildings.

Page 3 - 6

NETWORK CONNECTIONS

• Type 2 - Similar to Type 1 data cable, with four additional

unshielded twisted pairs of 24 AWG solid wire. The additional
wires are outside of the shield casing and are typically used for
voice communication. Type 2 is frequently used to wire cable
runs within the walls of buildings.

• Type 3 - Usually four unshielded twisted pairs (UTP) of 24

AWG solid wire for data or voice communication, such as
telephone lines. Used for cable runs in walls of buildings.

• Type 6 - Two STP of 26 AWG stranded wire for data. This type

is used in patch panels or to connect devices with wall jacks.
Due to the higher attenuation, Type 6 cable is good for up to 66
meters for every 100 meters of Type 1 cable (Type 6 cable
distance = 2/3 x Type 1 cable distance).

• Type 8 - One flat STP of 26 AWG stranded wire for under

carpet installation. Type 8 STP has the same characteristics as
Type 9 cabling.

• Type 9 - Similar to Type 1, but uses 26 AWG solid wire. Due to

the higher attenuation, Type 9 cable is good for up to 66 meters
for every 100 meters of Type 1 cable (Type 9 cable distance = 2/
3 x Type 1 cable distance).

3.3.2 Cable Lengths

Lobe length is the physical length of the cable connecting a PC to a
trunk coupling unit port on the ring concentrator. Lobe length
limits for the Token-Ring adapters are shown in Table 3-1 on the
following page. To determine the specific lobe link length, refer to
the manual for the concentrator to which your Token-Ring adapter
is connected.

with UL478, UL910, NEC 725-2(b), CSA, IEC, TUV, VDE Class A.
Meets FCC, Part 15, Class A limits.

65 meters
(213 feet)

3.5 ATTENUATION

Maximum attenuation for specific cable types is shown in
Table 3-2. Since there are two possible ring speeds, both
frequencies are listed, 4.0 MHz and 16 MHz. The attenuation
values include cables, connectors, and patch panels.

Page 3 - 8

NETWORK CONNECTIONS

Table 2:

Cable Type at 4 Mbps at 16 Mbps

STP (IBM Types 1 and 2 22 dB/Km 45 dB/Km
Voice Grade UTP (IBM Type 3) 56 dB/Km 131 dB/Km
STP (IBM Types 6 and 9) 33 dB/Km 66 dB/Km

3.6 IMPEDANCE

The characteristic impedance for UTP cable is 100 ohms ±15%. For
STP cable, the characteristic impedance is 150 ohms ±10%.

3.7 CROSSTALK

Is caused by signal coupling between the different cable pairs
contained within a multi-pair cable bundle. In shielded pair cables,
the effects of crosstalk are minimized.

3.8 NOISE

Can be caused by either crosstalk or externally induced impulses.
If noise induced errors are suspected, it may be necessary to re­route cabling away from potential noise sources (motors,
switching equipment, high current equipment), or to ensure that
the electrical wiring in the area is properly wired and grounded.

WARNING: It is the responsibility of the person who sells the
system of which the adapter will be a part to ensure that the total
system meets allowed limits of conducted and radiated emissions.
