SuperStack® II Switch 1000BASE-T Module (3C16978)

User Guide

INTRODUCTION

The SuperStack II Switch 1000BASE-T Module provides a Gigabit Ethernet module for the SuperStack II Switch 1100 (12 and 24 port), SuperStack II Switch 3300 (12 and 24 port), and SuperStack II Switch 3300 FX.

The module requires management software version 2.42 or later to be installed on the Switch. For instructions on upgrading management software, refer to the documentation supplied with your Switch.

The module conforms to the full duplex implementation of the Gigabit Ethernet standard IEEE 802.3ab. The module supports a 100 m cable segment, using Category 5 copper cabling and RJ-45 connectors, as defined in the ANSI/TIA/EIA-568-A Commercial Building Telecommunications Cabling Standard, and in the 1000BASE-T standard.

A white paper which describes 1000BASE-T technology and cabling requirements in more detail is available from the 3Com® Web site.
