CHAPTER 1  
INTRODUCTION  
Welcome to Cabletron Systems 7H02-06 Fast Ethernet  
SmartSwitchInterface 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.  
1.1 USING THIS MANUAL  
Chapter 1, Introduction, discusses the capabilities and special  
features of Cabletron Systems 7H02-06 Module. This chapter also  
includes a list of related manuals.  
Chapter 2, Network Requirements, contains a list of available  
FEPIMs and the network requirements that should be considered  
before installing the 7H02-06 Module.  
Chapter 3, Installation, contains instructions for installing the  
7H02-06 in the 7C03 MMAC SmartSwitch, the 7C04 Workgroup  
SmartSwitch or the 7C04-R Workgroup SmartSwitch.  
Chapter 4, Troubleshooting, contains instructions for using  
LANVIEW® (Cabletron Systems built-in diagnostic and status  
monitoring system).  
Chapter 5, Technical Specifications, provides detailed information  
about the physical characteristics of the 7H02-06 Module.

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 Cable Type 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.

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).

TROUBLESHOOTING  
The 7H02-06 Module uses LANVIEW, Cabletron Systems built-in  
visual diagnostic and status monitoring system.  
With LANVIEW LEDs the status of each transmit and receive port  
on the 7H02-06 Module can be determined, at a glance. This section  
discusses the function and purpose of the LEDs on the 7H02-06  
Module.

APPENDIX A  
The 7H02-06 module uses Fast Ethernet Interface Modules  
(FEPIMs) to provide front panel cable connections. The FEPIMs are  
user-installable. See the section ‘Installing an FEPIM’ on page 3-1.  
A.1 FE-100TX  
The FE-100TX is an RJ45 connector supporting Unshielded Twisted  
Pair (UTP) cabling.  
The slide switch on the FE-100TX determines the crossover status  
of the cable pairs. If the switch is on the X side, the pairs are  
internally crossed over. If the switch is on the = side, the pairs are  
not internally crossed over. Figure A-1 shows the pinouts for the  
FEPIM-100TX in both positions.

A.2 FE-100FX  
The FE-100FX shown in Figure A-2 supports multimode fiber optic  
cabling. The FE-100FX is equipped with an SC style port.  
Transmitter power specifications for the FE-100FX are listed in  
Table A-1 on the following page.

The transmitter power levels listed in Table A-1 are peak power  
levels after optical overshoot. A peak power meter must be used to  
correctly compare the values given below to those measured on  
any particular port. If power levels are being measured with an  
average power meter, add 3 dBm to the measurement to compare  
the measured values to the values listed below.
