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 guide, 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.
