CHAPTER 1
INTRODUCTION
Welcome to the Cabletron Systems VHSIM-G02 User’s Guide . This
manual describes the VHSIM-G02 and provides information concerning
features, installation, troubleshooting, information on Local Management,
and specifications for the VHSIM-G02 (Very High Speed Interface
Module).
A general working knowledge of IEEE 802.3z (Gigabit Ethernet),
IEEE 802.3ab (Gigabit Copper) and IEEE 802.3x (Flow Control and
Auto-Negotiation) data communications networks and their physical
layer components is helpful when installing the VHSIM-G02.
The VHSIM-G02 can be installed into compatible Cabletron Systems
2000 and 6000 series products.
The VHSIM-G02 (Figure 1-1) has two ports that provide Gigabit
Ethernet connections. There are two possible modes of operation for the
VHSIM-G02. In mode one, both ports are active and transmit/receive data
simultaneously. This mode can only be selected if the host platform has
16 or less fixed front panel ports. In mode two, one port is active and the
other is redundant. Redundancy is triggered based on link activity; if port
one loses link then port two becomes active. Port one is active by default.
The default mode for the VHSIM-G02 is redundancy.
Figure 1-1 VHSIM-G02
NOTE
The term “host platform” may be used to refer to the module or
standalone device in which the VHSIM-G02 is installed.

1-2 VHSIM-G02 User’s Guide
1.1 STRUCTURE OF THIS GUIDE
Read through this manual completely to familiarize yourself with its
content and to gain an understanding of the features and capabilities of
the VHSIM-G02. The following list provides an overview of each section
of this manual:
Chapter 1, Introduction , outlines the contents of this manual, describes
the VHSIM-G02 features and concludes with a web site address where
related manuals can be obtained.
Chapter 2, Installation , describes how to install a VHSIM-G02 into an
interface module or a standalone device.
Chapter 3, LANVIEW LEDs , describes how to use the VHSIM-G02
LEDs to monitor performance and status.
Chapter 4, Local Management , gives information on Local Management
for the VHSIM-G02.
Appendix A, VHSIM-G02 Specifications , lists the operating
specifications and regulatory compliance for the VHSIM-G02.
1.2 OVERVIEW
The VHSIM-G02 has two RJ45 ports for twisted pair connections to
Gigabit Ethernet networks. The VHSIM-G02 extends the functionality of
various Cabletron Systems interface modules or standalone devices by
providing high-speed uplink capability through copper Gigabit Ethernet
technology (IEEE 802.3ab).
VHSIM-G02 features include the following:
• RMON support (Statistics, History, Alarms, Events)
• Management
• Flow control and Auto-Negotiation (IEEE 802.3x)
1.2.1 LANVIEW Diagnostic LEDs
Cabletron Systems provides a visual diagnostic and monitoring system
called LANVIEW. The VHSIM-G02 LANVIEW LEDs help you quickly
identify transmit, receive, and link status. Chapter 3 provides information
on the VHSIM-G02 LEDs.

Document Conventions
VHSIM-G02 User’s Guide 1-3
1.2.2 Connectivity
The VHSIM-G02 supports two modes of operation for the Gigabit
interfaces. In one mode, the VHSIM-G02 supports one active and one
redundant Gigabit Ethernet twisted pair port. In the other mode, both of
the interfaces can be active at the same time, if the host platform has 16 or
less fixed front panel ports.
The VHSIM-G02 supports Gigabit Ethernet connections on the RJ45
ports using twisted pair. The VHSIM-G02 module supports the
IEEE 802.3ab Gigabit specification and the IEEE 802.3x specification for
flow control and auto-negotiation. The VHSIM-G02 operates in full
duplex mode.
