92 Configuring System Information
Managing Power over Ethernet
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.
Powered Devices are devices which receive power from the PowerConnect power supplies, for example
IP phones. Powered Devices are connected to the PowerConnect device via Ethernet ports. Powered
devices are connected via either all PowerConnect 3524P’s 24 FE ports or all PowerConnect 3548P’s
48 FE ports.
