Section 6. Managing Power over Ethernet Devices

Power over Ethernet

(PoE) provides power to devices over existing LAN cabling, without updating or modifying

the network infrastructure. Power over Ethernet removes the necessity of placing network devices next to power
sources. Power over Ethernet can be used with:

•

IP Phones

•

Wireless Access Points

•

IP Gateways

•

PDAs

•

Audio and video remote monitoring

Powered Devices are devices which receive power from the device power supplies, for example IP phones. Pow-
ered Devices are connected to the device via Ethernet ports.

PoE is enabled for the DXS-3227P only.

This section includes the following topics:

•

Defining PoE System Information

•

Defining PoE Interfaces
