Product Overview

Introduction

The 3Com Baseline Switch 2900 Family are Layer 2 Gigabit Ethernet switches developed by 3Com.
They are intelligent manageable switches designed for network environments where high performance,
high-density port distribution, and easy installation are required.
With 10/100/1000 Mbps Ethernet interfaces, the 3Com Baseline Switch 2900 Family are mainly
deployed at the access layer in enterprise networks requiring Gigabit to the Desktop (GTTD) application
and at the distribution layer in metropolitan-area networks (MANs). In the latter deployment, the 3Com
Baseline Switch 2900 Family provide GE electrical interfaces for user access or low-end switch
convergence in the downlink direction. Whereas, in the uplink direction, they are aggregated to
large-capacity Layer 3 switches or switches at the exchange office through their GE interfaces.
Table 1-1 shows the models and system specifications of the 3Com Baseline Switch 2900 Family.
