8H02-16 Overview
8H02-16 User’s Guide 1-3
1.3 8H02-16 OVERVIEW
The 8H02-16 is a standalone 16-port high-speed network switch device
that supports traditional switching (bridging). Ports 15 and 16 support
optional Fast Ethernet Interface Modules and can provide uplinks to
100BASE-TX or 100BASE-FX fast Ethernet networks.
The 8H02-16 is used to connect individual high-bandwidth user devices,
such as workstations, and provide a central switching point for multiple
Ethernet segments built using devices such as Cabletron Systems
HUBSTACK or other third party stackable devices.
The 8H02-16 is a tabletop unit that can also be installed in a standard
19-inch rack using the supplied rack mounting hardware.
The 8H02-16 has a universal ac power supply with automatic voltage
sensing that allows operation using 100–125 or 200–250 Vac, 50/60 Hz.
1.3.1 8H02-16 Features
The 8H02-16, shown in Figure 1-1, has the features listed below.
Figure 1-1 The 8H02-16
• Intel i960 RISC processor control
• 14 Port High-Speed Workgroup Switch with two optional ports for

Chapter 1: Introduction
1-4 8H02-16 User’s Guide
• Full Duplex Switched Ethernet (FDSE) support for 20 Mbps links to
bandwidth intensive users/servers
• Runtime IP Address Discovery that allows the 8H02-16 to send out a
RARP or BootP request to determine its IP address
• Manageable using Simple Network Management Protocol (SNMP)
and Remote Monitoring (RMON)
• Support for traditional switching services as well as for Cabletron
Systems S
ECURE F AST Switching Virtual Network technology
• Possible linking of existing stackable or third party hubs to 100 Mbps
Fast Ethernet backbones
• IEEE 802.3 compatibility with support for IEEE 802.1d and DEC
Spanning Tree Algorithms
• LANVIEW Diagnostic LEDs
1.3.2 Connectivity
The 8H02-16 connects to Ethernet networks or workstations through
fourteen RJ45 ports on the front panel. These ports support Unshielded
Twisted Pair (UTP) and Shielded Twisted Pair (STP) cables at lengths up
to 100 meters. The ports are IEEE 802.3 10BASE-T compliant.
The 8H02-16 has two front panel slots (ports 15 and 16) for optional Fast
Ethernet Interface Modules to support an uplink to 100 Mbps Ethernet
backbones or a high speed connection to a local server.
1.3.3 Full Duplex Switched Ethernet
Each switched Ethernet port supports full wire-speed Ethernet
communications and can be configured to operate in Full Duplex
Switched Ethernet mode.

8H02-16 Overview
8H02-16 User’s Guide 1-5
1.3.4 Management
Management of the 8H02-16 is accomplished using Local Management
tools or remote SNMP management stations. Out-of-band local
management is provided through the RS232 COM port on the front panel
using a VT100 terminal or a VT100 terminal emulator. In-band remote
management is possible through any SNMP compliant Network
Management Software.
1.3.5 Traditional Switching
The 8H02-16 provides traditional Switching or S ECURE F AST Switching
Virtual Network Services between all of the front panel interfaces
including the optional ports 15 and 16.
Through Cabletron Systems Synthesis framework, the 8H02-16 supports
operations in traditional Switching mode or S
ECURE F AST Switching
mode. S
ECURE F AST Switching allows for future migration to Virtual
Network technologies without requiring the replacement of existing
equipment.
1.3.6 Standards Compatibility
The 8H02-16 provides IEEE 802.1d Spanning Tree Algorithm (STA)
support to enhance the overall reliability of the network and protect
against “loop” conditions. The 8H02-16 supports a wide variety of
industry standard MIBs including RFC 1213 (MIB II), RFC 1271
(RMON), RFC 1371 (RS232 MIB), RFC 1493 (Bridge MIB) and RFC
1354 (FIB MIB). A full suite of Cabletron Systems Enterprise MIBs
provide a wide array of statistical information to enhance troubleshooting.
1.3.7 LANVIEW Diagnostic LEDs
LANVIEW diagnostic LEDs serve as an important troubleshooting aid by
providing an easy way to observe the status of individual ports and overall
network operations. Chapter 4 provides details about the 8H02-16
LANVIEW LEDs.

1.4 LOCAL MANAGEMENT FEATURES
Local Management provides the tools that allow management of the
8H02-16 and any of the optional Fast Ethernet Interface Modules
installed as ports 15 and 16. It also allows the following tasks to be
performed:
• Assign an IP address and subnet mask to the 8H02-16.
• Select a default gateway and default interface.
• Control local and remote access.
• Designate workstations to receive SNMP traps from the 8H02-16.
• Configure module specific SNMP MIB objects including the IETF
Bridge MIB objects and many of the RMON MIB objects.
Chapter 6 provides detailed information about Local Management.
1.5 OPTIONAL FEATURES
The two optional Memory Upgrade Kits for the 8H02-16 SmartSwitch
are listed below:
• The 8H02-16-MEM-UGK Memory Upgrade Kit provides an 8 MB
DRAM SIMM that allows the 8H02-16 to run SFS (Secure Fast
Switching) and all groups of RMON.
• The 8H02-8D/4F-ADV Advanced Memory Upgrade Kit provides
8 MB DRAM, 4 MB of FLASH with a preloaded image, and image
diskettes that allows the 8H02-16 to run VLAN (Virtual Local Area
Network), SFS, and RMON.

Document Conventions
