Introduction - 3Com EtherLink 3C509B User Manual

Introduction

The 3Com
family of third-generation Ethernet adapters. These adapters
include 16-bit Industry Standard Architecture (ISA) and
32-bit Extended Industry Standard Architecture (EISA)
adapters for both coax and 10BASE-T connections. This
manual contains installation, configuration, and diagnostic
information about the following adapters:
16-bit ISA adapters
– 3C509 coax
– 3C509-TP 10BASE-T
– 3C509-COMBO with both 10BASE-T and coax
32-bit EISA adapters
– 3C579 EISA coax
– 3C579-TP EISA 10BASE-T
The five adapters are functionally identical; they differ only
in the layout of the components on each board, the bus
connectors, and the backplates. The name EtherLink III
adapter is used in this manual to refer to all five adapters
unless otherwise specified.
EtherLink III adapters connect your IBM
computer or compatible to an Ethernet network wired
with IEEE 802 standard 10BASE-2 or 10BASE-5 coaxial
cable, or 10BASE-T twisted-pair cable.
