INTRODUCTION

The 3Com SuperStack™ II Hub 100 Management Unit provides
Simple Network Management Protocol (SNMP) management capabilities
for 3Com’s SuperStack II Hub 100 repeater units. The Management Unit is a
member of the SuperStack II family of stackable network devices. A
managed stack is composed of up to seven repeaters (hubs) and one
Management Unit, which can be placed anywhere in the stack. The stack
can also optionally include up to two SuperStack II Redundant Power
System (RPS) units, which ensure fail-safe operation and constant power to
the stack.

The Management Unit supports 100BASE-T Fast Ethernet, which is an
extension of the Ethernet IEEE 802.3 specifications. The 100BASE-T
specification supports the following 100 Mbps media options:

■ 100BASE-TX (two-pair Category 5 UTP cabling)

■ 100BASE-T4 (four-pair Category 3, 4, or 5 UTP cabling)

■ 100BASE-FX (two-strand fiber cabling)

This guide discusses only the SuperStack II Hub 100 Management Unit. For
detailed information on the 3Com SuperStack II Hub 100 T4, Hub 100 TX, or
the 100BASE-TX, 100BASE-T4, and 100BASE-FX transceiver interface
