Chapter 1 Getting to Know Your Switch

The following figure depicts a typical segment bridge application of the Switch in an enterprise 
environment. The two networks (RD and Sales), the standalone server and the computers can all 
communicate with each other and share all network resources.

Bridging Example 

1.4  Power Over Ethernet (PoE)

The PoE function is available for ES1100-8P and ES1100-16P only. 

ES1000-8P and ES1100-16P has FE PoE ports and supports IEEE 802.3af Power over Ethernet 
(PoE).

A powered device (PD) is a device such as an access point or a switch, that supports PoE (Power 
over Ethernet) so that it can receive power from another device through a 10/100Mbps Ethernet 
port.

In the figure below, the IP camera and IP phone get their power directly from the Switch. Aside 
from minimizing the need for cables and wires, PoE removes the  hassle of trying to find a nearby 
electric outlet to power up devices.
