MANAGING POWER OVER ETHERNET DEVICES
NOTE: This chapter is valid only when using devices
on which Power over Ethernet (PoE) is
supported.
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 in the following applications:
 IP Phones
 Wireless Access Points
 IP Gateways
 Audio and Video Remote Monitoring
Powered Devices are devices that receive power from the device power supplies, for example IP phones. Powered Devices
are connected to the device via Ethernet ports. Guard Band protects the device from exceeding the maximum power level.
For example, if 400W is the maximum power level, and the Guard Band is 20W, if the total system power consumption
exceeds 380W no additional PoE components can be added. The accumulated PoE components power consumption is
rounded down for display purposes.
This section includes the following topics:
 Defining PoE Port Information
 Configuring PoE System
