Congratulations on your purchase of the 8-Port 10/100Mbps Fast Ethernet Switch with

4-Port PoE. This Switch integrates 100Mbps Fast Ethernet and 10Mbps Ethernet

network capabilities in a highly flexible package. And this switch’s Port-1 to Port-4 are

Power over Ethernet (PoE) ports, and it will automatically detects the presence of IEEE

802.3af-compliant powered device (PD) and provides power through the Port-1 to

Port-4. The switch provides up to 15.4 W for PoE port and can be used to WLAN

access point, IP phone, video camera and other PD devices. The Switch will

automatically detect the network appliance’s requirements, and the switch will supplies

the required power current to each appliance.

In this

uide, the term “Switch” (first letter upper case) refers

to your 8-Port 10/100Mbps Fast Ethernet Switch with 4-Port

PoE and “switch” (first letter lower case) refers to other

Ethernet switches.

1. Introduction

This chapter describes the features of the Switch and some background information

about Ethernet/Fast Ethernet switching technology.

1.1 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 guarantee cost effective and high performance Fast Ethernet solutions

in the years to come.

100Mbps Fast Ethernet is a new 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.
