Quick Start

Quick Start

Installation Procedure

If you are an experienced user , and you are familiar with your computer, its operating system, and the installation of network adapters - you can follow this simple installation procedure, and use the subsequent chapters in this manual for reference if necessary.

CAUTION

The E2200 network adapters are sensitive to static discharges. Touch the metal chassis of your computer to discharge any static electricity. Hold the adapter by the top of the metal bracket and the opposite top corner. Avoid contact with the adapter’s expansion bus edge connector or any of the adapter’s components. Failure to observe all static precautions could result in damage to the adapter. We recommend the use of an antistatic wrist strap.

Plug and Play Systems

“Plug and Play™” is an automatic configuration scheme. Your computer can be considered a “Plug and Play” system if it uses either a Plug and Play BIOS, or a Plug and Play operating system, or a Plug and Play Configuration Manager device driver. Plug and

Play software will automatically set the parameters of IRQ, I/O

Base Address, and DMA channel for all adapters that are plugged into the system at power up time.

WARNING

Make sure power to your PC is switched off and the power cord unplugged before you open the chassis. Opening the PC chassis with power on can subject you to a serious electrical hazard.

At this time, if you need to install a Boot ROM, see Section 2.3.1,

Installing a Boot ROM . Otherwise follow the steps outlined on the next page.

INTRODUCTION

1.4

FDSE TECHNOLOGY OVERVIEW

1.4.1

Why Full-Duplex Switched Ethernet?

The E2200 Series adapters can operate in both Standard Ethernet mode, and Full-Duplex Switched Ethernet mode. There are many benefits to be gained from operating in Full-Duplex Switched

Ethernet (FDSE) mode. Full-Duplex Ethernet operation can double the throughput of an existing system while eliminating rewiring costs, as it doubles network speed from 10 Mbps to 20 Mbps.

Full-Duplex operation is a prerequisite to the interactive, multimedia network applications of the future. In pursuit of this goal, Cabletron Systems is participating in the standards process with the Full-Duplex Switched Ethernet Consortium (FDSEC), to create an industry standard that will allow various manufacturer’s products to coexist in twisted pair and fiber optic networks which will have an aggregate bandwidth of 20 Mbps.

When increased bandwidth is required, users with E2200 Series adapters will be able to simply upgrade their shared-access

10BASE-T hubs to Full-Duplex Switched Ethernet hubs. No other hardware changes will be required at the Network Interface

Controller (NIC) end of the Ethernet links to operate in Full

Duplex Switched Ethernet mode.

In order to provide a full-duplex service based on existing IEEE

802.3 architecture, these prerequisites must be met:

• The network fabric must be a switched-access medium.

• The physical media must provide two channels (Transmit and

Receive).

• The full-duplex 802.3 network must be run over shielded twisted pair (STP), unshielded twisted pair (UTP), or fiber optic cable. A switching hub must be used (for three or more nodes) to interconnect the full-duplex segments.

Page 1 - 6

INTRODUCTION

In order to implement FDSE, we must define three key components: the operation of the MAC layer entity, the operation of the MAU, or transceiver, and the operation of an Auto-Detection mechanism (for Auto-Detect of FDSE).

The most important, and fundamental requirement for FDSE is that FDSE technology be backward-compatible with standard

802.3 Ethernet technology.

1.4.2

MAC Layer

The Full Duplex Switched Ethernet MAC layer allows for the simultaneous reception and transmission of 802.3 Ethernet frames.

The entire MAC layer provides separate processing paths for the transmitter and receiver, including separate CRC generation and checking. The decision to operate in full-duplex mode will be made by the FDSE Auto-Detect mechanism.

1.4.3

MAU Operation

The MAU, or transceiver, will signal the MAC layer that FDSE mode of operation is desired when either of two events occurs: a

“Hardware” register is set on the MAU, or an FDSE Auto-Detect mechanism indicates that FDSE operation is desired, and switches hardware to FDSE mode.

When the MAU detects that FDSE operation is desired, it will do three things: disable the standard Ethernet Collision detector and the collision LED, disable the loopback signal, and disable the SQE signal.

These changes are required for the following reasons: collision is impossible within FDSE, and future AUI transceivers will have support for FDSE.

Page 1 - 7

INTRODUCTION

1.4.4

FDSE Cabling

FDSE will run on existing category 3 and category 4 UTP cabling.

There is no need to change cable media to upgrade to FDSE technology.

However, for new wiring plant designs, category 5 cabling will allow upgrading to 100 Mbps Ethernet operation in the future.

Category 5 UTP cable is specified for desktop wiring distances up to 100 meters and data rates up to 100Mbps.

Two Technical System Bulletins (TSB) were issued by EIA/TIA after ANSI EIA/TIA 586.

• TSB-36 classifies UTP cables into categories 3, 4, and 5, and provides characteristic and performance values at particular data rates.

• TSB-40 classifies connector hardware (punch-down blocks, patch panels, wall jacks, etc.) into categories 3, 4, and 5, and also provides characteristic and performance values at particular data rates.

Anyone considering installing a new cable plant should consult all three documents. They are available through your local EIA publications office - call 1-800-854-7179.

Cabletron Systems is committed to delivering FDSE products in strict conformance with industry standards and Cabletron’s

Integrated Network Architecture (INA).

2.1

INSTALLATION REQUIREMENTS

The E2200 Series adapters are designed for any computer that supports ISA or EISA Bus architecture. Installation of the

Cabletron E2200 Series network adapters is simple and straightforward.

2.1.1

Plug and Play Compatibility

The E2200 type Ethernet network adapters are “ Plug and Play ” compatible. Plug and Play is most often implemented in the computer’s system BIOS, or the operating system proper (as in

Microsoft Windows 95™).

Each E2200 Series adapter is shipped with a factory default configuration stored in the adapter’s configuration EEPROM. If the preset default Plug and Play parameters are not satisfactory for your specific system requirements, and your system ’s Plug and

Play BIOS cannot resolve the conflict, contact Cabletron Technical

Support (See page 1-2, Getting Help ).

Page 2 - 1

INSTALLATION

2.1.2

Unpacking the Adapters

The network adapter and software are shipped separately. The hardware package should contain one box with a network adapter and this manual.

PC, with the E2200 series adapter, to communicate on the Ethernet network. Network operating system software drivers are supplied on the Cabletron software diskette that accompanied the adapter.

The drivers are grouped in subdirectories that contain readme files to explain recent changes in procedure, etc. The Network Software

Installation Guide , included with the Cabletron software diskette(s), contains detailed instructions for installing network drivers.

The E2200 series adapters contain configuration information, stored in EEPROM. The adapters are shipped with a set of default parameters already installed. Table 2-1, on the following page, lists the default parameters.

If these parameters are acceptable, no further configuration of the adapter is necessary and you may proceed to install network drivers (see the Network Software Installation Guide for instructions on installing drivers.

NOTE

If you wish to change the default parameters in your adapter, you MUST configure it before loading network drivers. See Section 2.6.1, QuickSet™ Configuration

Utility.

The QuickSet™ Configuration Utility

The E2200 series Ethernet adapters do not have configuration switches or jumpers; the configuration information is written into the adapter at the factory. You can use the Cabletron QuickSet configuration utility to change the default configuration parameters.

QuickSet is a user-friendly, menu-driven application that lets you customize the configuration of I/O port address, DMA channel, media port, hardware interrupt level, boot ROM address, and memory access speed, for the E2200 series adapters. The following section contains a brief description of the operation of the QuickSet utility.

SECONDARY MEDIA

CHAPTER 3 SECONDARY MEDIA

This section contains instructions for connecting your adapter’s secondary media port to an Ethernet network. The adapter’s secondary media port can be connected to the Ethernet network via any of the following means: a second 10BASE-T link, a Thin-

Net coaxial connection, a fiber optic link, a wireless hub, or an AUI port and an external Ethernet transceiver.

You should have selected the port to use during the configuration procedures. If you did not, run the QuickSet configuration utility on the Cabletron Software diskette. See Section 2.6.1, The

QuickSet Configuration Utility , for more detailed instructions.

We recommend that you run the diagnostic program before connecting your PC to a network segment. You can run the diagnostic program from your backup copy of the Cabletron

Software diskette.

CAUTION

If you wish to run the diagnostic program, you must make sure that no E22XX network drivers are loaded. Make sure drivers are not being autoloaded by your system.

If you encounter problems running diagnostics, power cycle your computer. You may load E22XX drivers when diagnostics are completed.

3.1

CONNECTING TO A THIN-NET SEGMENT

To connect a thin coaxial 10BASE-2 segment to an adapter with a

BNC port, attach a BNC tee-connector (see Figure 3-1, on the following page) to the adapter’s BNC port.

Slip the female end of the BNC tee connector over the (male) BNC port. Then, line up the tee connector slots with the pins on the port connector.

Page 3 - 1

SECONDARY MEDIA

Push the tee connector in until you engage the pins and rotate the tee connector clockwise until it locks.

Next, attach the thin-net segment (see Figure 3-1) to one of the male connections on the BNC tee-connector. Rotate and lock the collar on the Thin-Net segment, as above.

Each segment attached to the tee-connector must be terminated (at an end point). If a segment is not attached to (the other) of the male connections on the tee-connector, then a terminator (see

Figure 3-1,View A) must be placed on that connection.

Attach another thin-net segment (see View B) or a terminator

(View A) to the other male connection on the tee-connector.

CONNECTING TO AN EXTERNAL TRANSCEIVER

3.2.1

AUI Port

Figure 3-2. Connecting an AUI Cable

Any adapter with an AUI port can be connected to the network via an external transceiver and an AUI cable. The AUI port should have been selected during adapter configuration procedures.

Page 3 - 3

SECONDARY MEDIA

To connect an AUI cable to your adapter, attach an external transceiver to the network segment to which the adapter is going to be attached. Refer to the applicable transceiver manual. Attach the female end of an AUI cable, no more than 50 meters in length, to the transceiver.

Attach the male connector on the AUI cable to the adapter’s AUI port and tighten the securing screws.

CONNECTING TO A FIBER OPTIC LINK

The physical communication link consists of two fiber optic strands between the adapter and the other Ethernet fiber optic device on the link: Transmit (TX) and Receive (RX).

The adapter Tx connects to the Rx of the Ethernet device. The adapter Rx connects to Tx of the Ethernet device.

Page 3 - 4

SECONDARY MEDIA

We recommend that you label the fiber optic cable to indicate which fiber is Receive and which is Transmit. When you buy fiber optic cable from Cabletron Systems, it is labeled so that at one end of the cable the fiber is labeled 1, and the other fiber is labeled 2.

This pattern is repeated at the other end of the cable.

ST type fiber optic connectors attach to ST ports in the same way that BNC connectors attach to BNC ports. You slide the connector into the port with the alignment key on the connector inserted into the alignment slot on the port. Then turn the connector until it is locked in place (see Figure 3-3, below).

NOTE

Do not touch the ends of the fiber optic strands and do not let the ends come in contact with dust, dirt, or other contaminants. Contamination of the ends can cause data transmission problems. If the ends become contaminated, clean them with denatured alcohol using a soft, clean, lint free cloth. If this does not work, use a fiber optic polishing kit to polish the end of the strand.

Page 3 - 5

SECONDARY MEDIA

To connect a fiber optic segment, attach the fiber labeled 2 to the adapter’s Transmit port (light gray). Attach the fiber labeled 1 to the adapter’s Receive port (dark gray).

At the other end of the fiber optic cable, attach the fiber labeled 1 to the Transmit port of the applicable device. Attach the fiber labeled

2 to the Receive port of the applicable device. At this time you should check to see that the adapter’s Link LED is lit. If the LED is not lit, verify that power is on for the PC, and check that the power is on for the device at the end of the fiber optic cable.

Verify that the fiber optic strands are “crossed over” at the far end device, Transmit to Receive by checking the labeling on each strand. Verify that the fiber connection meets the dB loss specifications outlined in Appendix A, Technical Specifications. If a link still has not been established, contact Cabletron Systems

Technical Support (see Section 1.2, Getting Help).

Twisted Pair Requirements

Length

10BASE-T transceivers must be able to transmit over a 100 meter link (328 feet) using 24 AWG unshielded twisted pair wire. 10BASE-T specifies no maximum link length.

NOTE

Due to cable delay, the maximum link length is always limited to about 200 meters (656 feet), regardless of the type of cable.

Generally, you can achieve links of up to 150 meters (492 feet) for unshielded and shielded twisted pair cable. For each connector or patch panel, subtract 12 meters (39.4 feet).

Page A - 2

TECHNICAL SPECIFICATIONS

This allows links of up to 126 meters (413.4 feet) using standard

24 AWG UTP wire and two patch panels. Higher quality, low attenuation cables may be required if you want to use links greater than 126 meters.

Insertion loss

The insertion loss is 11.5 dB maximum for 10BASE-T links at all frequencies between 5.0 and 10.0 MHz. This includes attenuation of cables, connectors, patch panels, and reflection losses due to impedance mismatches.

Impedance

Unshielded twisted pair cable is typically between 85 and

110 ohms. Shielded cable, such as type 1 cable, is typically

150 ohms which can increase the signal reflection. Cabletron

Systems 10BASE-T twisted pair products will work on shielded twisted pair cable with 75 to 165 ohms impedance.

Jitter

Not more than 5.0 nanoseconds for a 10BASE-T link.

Delay

Must not exceed 100 nanoseconds for a 10BASE-T link.

Crosstalk

Crosstalk is caused by signal coupling between cable pairs within a multi-pair cable bundle. Crosstalk should not be a problem if the cable meets all other requirements.

Noise

Noise can be caused by either crosstalk or externally induced impulses. Impulse noise can cause data errors if the impulses occur at very specific times during data transmission. If you suspect noise-related data errors, it may be necessary for you to reroute the cable or eliminate the source of the impulse.

Temperature

Multi-pair, PVC 24AWG telephone cables have an attenuation of approximately 8 to 10 dB/100 meters at 20

Page A - 3

TECHNICAL SPECIFICATIONS

The attenuation of PVC insulated cable varies significantly with temperature. At temperatures greater than 40

C, we strongly recommend that you use plenum rated cables to ensure that cable attenuation remains within specification.

A.1.3

Thin-Net Requirements

Cable

Must be 50 ohm RG-58A type coaxial cable.

Length

Must be no longer than 185 meters (607 feet).

Termination

A 50 ohm terminator must be installed at the far end of each

Thin-Net segment.

Connections

A maximum of 30 connections can be used throughout a thin coaxial segment for host connections. If an excessive number of barrel connections are used within the cable segment, i.e., finished wall plates with BNC feed-throughs, then a reduced number of host connections may be required.

A.1.4

AUI Cable Requirements

Type

The AUI cable must be Ethernet Version 1, Version 2, or IEEE

802.3, 10BASE-5 type cable that matches the Ethernet device attached to the AUI port.

Length

The AUI cable must not exceed 50 meters (164 feet) if 24 AWG

AUI cable is used. If 28 AWG AUI cable is used, then the maximum cable length is 16 meters (52 feet).

Page A - 4

TECHNICAL SPECIFICATIONS

A.1.5

Fiber Optic Requirements

Cable

The fiber optic link segments should consist of either 50/125 micrometer, 62.5/125 micrometer, or 100/140 micrometer fiber optic cabling.

Attenuation

Cable must be tested with a fiber optic attenuation test set adjusted for 850 nanometer wavelength. This test verifies that the signal loss in the cable is acceptable. Attenuation limits for various cable types are listed below:

-3.0 dB or less for a 50/125 micrometer fiber cable segment

-16.0 dB or less for a 62.5/125 micrometer fiber cable segment

-19.0 dB or less for a 100/140 micrometer fiber cable segment

Fiber Optic Budget

The fiber optic budget and total network propagation delay should be calculated before fiber runs are incorporated in any network design.

Fiber optic budget is the combination of optical loss of the fiber optic cable, in-line splices, and fiber optic connectors.

Propagation delay is the time it takes a packet to travel from the sending device to the receiving device.

Length

The maximum fiber optic cable length is 2Km (6558 feet), if system budgets are met. However, IEEE 802.3 FOIRL (Fiber

Optic Inter-Repeater Link) specifications specify a maximum of

1 Km (3279 feet).
