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 which 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 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, therefore remove value after
decimal point.
