FCC NOTICE

This device complies with Part 15 of the FCC rules. Operation is subject
to the following two conditions: (1) this device may not cause harmful in­terference, and (2) this device must accept any interference received, in­cluding interference that may cause undesired operation.

NOTE:

limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial
environment. This equipment uses, generates, and can radiate radio fre­quency energy and if not installed in accordance with the operator’s
manual, may cause harmful interference to radio communications. Op­eration of this equipment in a residential area is likely to cause interfer­ence in which case the user will be required to correct the interference
at his own expense.

WARNING:

expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.

This equipment has been tested and found to comply with the

Changes or modifications made to this device which are not

DOC NOTICE

This digital apparatus does not exceed the Class A limits for radio noise
emissions from digital apparatus set out in the Radio Interference Reg­ulations of the Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dé­passant les limites applicables aux appareils numériques de la class A
prescrites dans le Règlement sur le brouillage radioélectrique édicté par
le ministère des Communications du Canada.

NOTICE:

To insure FCC and DOC compliance and proper operation of

the ST-500 transceiver, SHIELDED transceiver cables must be used.

CHAPTER 1

INTRODUCTION

Welcome to the Cabletron Systems’ ST-500 Ethernet/IEEE 802.3
Transceiver with LANVIEW Installation Guide. This guide provides in-

stallers and service technicians with information required to install and,
if necessary, diagnose network problems.

Prior to installing and operating the ST-500 transceiver, read through
this manual completely to become familiar with its content and to gain an
understanding of the ST-500 features. A general working knowledge of
Ethernet/802.3 networks is helpful when installing the transceiver. De­tailed specifications are contained in Appendix A.

1.1 ST-500 Features

Cabletron System’s ST-500 Ethernet/IEEE 802.3 Transceiver with LAN­VIEW provides a method of connecting to an Ethernet or IEEE 802.3
controller via a host compatible transceiver cable. The ST-500 transceiv­er is compatible with Ethernet Version 1.0 specifications (September

1980), Ethernet Version 2.0 specifications (November 1983), and IEEE

802.3 standard (1983) for a 10-Mbps Medium Access Unit (MAU).
The ST-500 transceiver consists of two major components; a transceiver

body, and a tap. The type of media used in the network determines the
style of tap to install on the transceiver body (see Figure 1-1).

CHAPTER 1:

The type of tap provided with the transceiver body defines one of four
models of the ST-500 transceiver. The four models are:

ST-500 Features

1.1.1 LANVIEW LEDs

The ST-500 transceiver has five LANVIEW LEDs that monitor network
activity (transmit, receive and collision present), power status, and heart­beat (SQE) test status. These LEDs are described in Table 1-1. They
serve as a useful tool to quickly diagnose physical layer problems.

Table 1-1. LANVIEW LEDs

LED DESCRIPTION

PWR Power - On when the transceiver is receiving power

from the attached node.

SQE Signal Quality Error Test - On if the Heartbeat (SQE)

test is enabled.

XMT Transmit - On during the transmission of packets from

the host.
RCV Receive - On to indicate traffic on the network.
CLN Collision Present - On when a collision is detected by

the transceiver.

1.1.2 Heartbeat (SQE) Test

The ST-500 transceiver supports the Heartbeat (SQE) test. An internal
switch is provided to enable or disable the heartbeat (SQE) test. The sig­nal quality error (SQE) feature is used by some hosts to verify collision
signal path.

When the SQE test is enabled, the transceiver sends a 10-MHz burst on
the collision lead after transmissions. The burst must begin between 600
and 1600 ns after the end of the packet and must last for 500 to 1500 ns
(see Figure 1-2). The times are measured at the transceiver connector.
There is no collision test signal when just receiving.
