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 in-
terference, and (2) this device must accept any interference received, in-
cluding interference that may cause undesired operation.
NOTE:
This equipment has been tested and found to comply with the
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 fre-
quency energy and if not installed in accordance with the operator’s
manual, may cause harmful interference to radio communications. Op-
eration of this equipment in a residential area is likely to cause interfer-
ence in which case the user will be required to correct the interference
at his own expense.
WARNING:
Changes or modifications made to this device which are not
expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
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 Reg-
ulations of the Canadian Department of Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dé-
passant 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.

VCCI NOTICE
This equipment is in the 1st Class Category (information equipment to
be used in commercial and/or industrial areas) and conforms to the stan-
dards set by the Voluntary Control Council for Interference by Informa-
tion Technology Equipment (VCCI) aimed at preventing radio
interference in commercial and/or industrial areas.
Consequently, when used in a residential area or in an adjacent area
thereto, radio interference may be caused to radios and TV receivers,
etc.

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
thismanualcompletely tobecome familiarwithits contentand togainan
understanding of the ST-500 features. A general working knowledge of
Ethernet/802.3 networks is helpful when installing the transceiver. De-
tailed specifications are contained in Appendix A.
1.1 ST-500 Features
Cabletron System’s ST-500 Ethernet/IEEE 802.3 Transceiver with LAN-
VIEW provides a method of connecting to an Ethernet or IEEE 802.3
controller via a host compatible transceiver cable. The ST-500 transceiv-
er 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).
TheST-500transceiverconsistsoftwomajorcomponents;atransceiver
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:
INTRODUCTION
Page 1-2 ST-500 INSTALLATION GUIDE
The type of tap provided with the transceiver body defines one of four
models of the ST-500 transceiver. The four models are:
•
ST-500-00
- transceiver body only (no tap included)
•
ST-500-01
- with non-intrusive (stinger style) Ethernet tap
•
ST-500-02
- with N-Series (intrusive) Ethernet tap
•
ST-500-03
- with BNC (Thin-net) tap

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 heart-
beat (SQE) test status. These LEDs are described in Table 1-1. They
serve as a useful tool to quickly diagnose physical layer problems.
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 sig-
nal 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
thecollision leadaftertransmissions.Theburst mustbegin between600
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.
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.

CHAPTER 2
INSTALLATION
This chapter provides instructions for installing the three types of taps
supported by the ST-500 transceiver (see Figure 1-1). After unpacking
thetransceiverand configuringtheHeartbeat(SQE)testswitch,perform
the tap installation procedure that is applicable to the transceiver model.
2.1 Unpacking the ST-500 Transceiver
Open the package containing the ST-500 transceiver and check its con-
tents:
• 1 ST-500 transceiver body
• 2 Flat-head screws for attaching tap to transceiver
• 1 Cabletron Tap Kit (1K-TAP-01, 02, or 03)
• 1 Cabletron 1K-500 Installation Kit (for ST-500-01 only)
• 1 Installation guide
Inspect the ST-500 transceiver for damage. If it is damaged, contact
Cabletron Systems’ Customer Service. Save the shipping materials for
possible future shipment of the transceiver.
Note:
Taps may be installed and capped for future use. If extra taps are
required, the type of tap need only be called out. (Tap-01, Tap-02,
Tap-03)
2.2 Items Needed to Install the ST-500 Transceiver
To install the transceiver, the following items are needed:
• Cabletron Tap Kit
• Small flat-blade screw driver
• Cabletron 1K-500 Installation Kit (for ST-500-01 only, includes a
coring tool)
