INTRODUCTION 
This chapter describes the features of the FSW-1670TX 
8+8POE 10/100Mbps Web Smart Switch and some background 
information about Ethernet/Fast Ethernet switching technology. 
Fast Ethernet Technology 
The growing importance of LANs and the increasing complexity 
of desktop computing applications are fueling the need for high 
performance networks. A number of high-speed LAN 
technologies have been proposed to provide greater bandwidth 
and improve client/server response times.  Among them, 
100BASE-T (Fast Ethernet provides a non-disruptive, smooth 
evolution from the current 10BASE-T technology.  The non-
disruptive and smooth evolution nature, and the dominating 
potential market base, virtually guarantees cost-effective and 
high performance Fast Ethernet solutions. 
100Mbps Fast Ethernet is a standard specified by the IEEE 
802.3 LAN committee.  It is an extension of the 10Mbps 
Ethernet standard with the ability to transmit and receive data at 
100Mbps, while maintaining the CSMA/CD Ethernet protocol. 
Since the 100Mbps Fast Ethernet is compatible with all other 
10Mbps Ethernet environments, it provides a straightforward 
upgrade and takes advantage of the existing investment in 
hardware, software, and personnel training.
