Welcome to Cabletron Systems 7H02-06 Fast Ethernet
SmartSwitch
™
Interface Module Installation Guide. This guide is a
simple reference for installing and using the 7H02-06 Module.
Before installing the module, carefully read this manual to gain a
full understanding of its capabilities.
The 7H02-06 Module is a six port Fast Ethernet module that
supports 10/100 operation in both half and full duplex. The 7H02-
06 Module supports auto negotiation allowing it to automatically
use the fastest link both it and the attached device are capable of.
Connectivity to the ports is provided by 5 RJ45 connectors and one
Fast Ethernet Port Interface Module (FEPIM), allowing either
Category 5 twisted pair or multimode fiber optic cabling. This
module connects to a network and the 7X00 SmartSwitch Control
Module in the 7C03, 7C04 or 7C04-R MMAC SmartSwitch via a
SmartSwitch bus.

Introduction
1.2 THE 7H02-06 MODULE
The 7H02-06 Module provides six Fast Ethernet ports via 5 RJ45
connectors and one FEPIM. The 7H02-06 Module can be installed
in:
• The 7C03 MMAC SmartSwitch
• The 7C04 Workgroup SmartSwitch Chassis
• The 7C04-R Workgroup SmartSwitch Redundant Chassis
The 7H02-06 Module has one backplane connection and six front
panel connections. The backplane connection provides power to
the 7H02-06 Module and a channel for communication with the
7X00 SmartSwitch Control Module. The six front panel ports
provide Category 5 Twisted Pair (UTP) and one user configurable
port for UTP or multimode fiber optic connectivity (through the
FEPIM).
1.2.1 CableType and FEPIMs
The 7H02-06 module has six front panel connectors that interface to
the 7X00 SmartSwitch through the chassis backplane. 100 Base-TX
connections are provided through 5 RJ45s; one FEPIM provides 100
Base-TX (via RJ45) or 100 Base-FX (via multimode SC).
Note: UTP operates at 10/100 Mbps, while Fiber operates at 100 Mbps.
Both UTP and Fiber are capable of half or full duplex operation.

Introduction
Ring to be used with the 7H02-06 Module. These modules provide
the capability to share data without the use of external bridges or
routers.
The 7C03 MMAC SmartSwitch is a unique module that can be
installed in an MMAC Series chassis. The 7C04 Workgroup
SmartSwitch and the 7C04-R Workgroup SmartSwitch are stand-
alone chassis that provide the same functions.
1.3 FEATURES
The 7H02-06 provides Fast Ethernet connectivity via 5 front panel
RJ45 connectors and one FEPIM, and also includes the following
features:
• LANVIEW LEDs
• FEPIMs
• Fixed connectivity ports
1.3.1 LANVIEW LEDs
The 7H02-06 Module incorporates LANVIEW - Cabletron Systems
status monitoring and diagnostic system. Should a problem arise,
such as a power failure, the LANVIEW LEDs help you diagnose the
problem.
The 7H02-06 Module incorporates the following LANVIEW LEDs:
• Transmit (TX) LED
• Receive (RX) LED
For more information about the LANVIEW LEDs and the reset
switch on the 7H02-06 Module, refer to Chapter 4, Troubleshooting.

Introduction

1.3.2 FEPIMs
The front panel connections are standard Cabletron FEPIMs.
Currently, the 7H02-06 supports the following two FEPIMs:
• FE-100TX (see Figure 1-2). The FE-100TX allows Fast Ethernet
connectivity using Category 5 Twisted Pair (UTP) cabling with
one RJ45 connector.
Figure 1-2. FE-100TX PIM.
• FE-100FX (see Figure 1-3). The FE-100FX allows Fast Ethernet
connectivity using multi-mode fiber optic cabling with SC
connector.
Figure 1-3. FE-100FX PIM.
Refer to Appendix A of this manual for the specifications for these
FEPIMs.
1.3.3 Connectivity
The 7H02-06 Module has one backplane connection and five front
panel RJ45 connections and one FEPIM connection. The backplane
connection provides power to the 7H02-06 Module and a channel
for communication with the 7X00 SmartSwitch Control Module.
The six front panel ports provide Category 5 Twisted Pair (UTP)
and/or multimode fiber optic connectivity.

CHAPTER 3
INSTALLATION
This chapter contains instructions for unpacking and installing the
7H02-06 Module in the 7C03, 7C04, 7C04-R MMAC SmartSwitch.
Also included in the chapter are instructions for the front panel
FEPIMs.
3.1 UNPACKINGTHE 7H02-06 MODULE
Unpack the 7H02-06 Module by using the following steps:
1. Carefully remove the module from the shipping box. (Save the
box and packing materials in the event the module must be
reshipped.)
2. Remove the module from the plastic bag. Observe all
precautions to prevent damage from Electrostatic Discharge
(ESD).
3. Carefully examine the module and check for damage. If damage
exists, DO NOT install the module; contact Cabletron Systems
Technical Support.
3.2 INSTALLING FEPIMS
The 7H02-06 module is shipped without an FEPIM. To install an
FEPIM, follow the procedure below:
1. Remove the module if it is installed in the 7C03 MMAC
SmartSwitch chassis (follow the procedure in Section 3.3.2.)
Note: The procedure for removing the module depends upon the chassis
(7C03,7C04 or 7C04-R) the module is installed in. See the
applicable removal procedure contained within the following pages.
2. Remove the module faceplate by removing the 3 screws on the
bottom of the module. Carefully remove the module faceplate
exposing the slot for the FEPIM (see Figure 3-1).
