PoE Configuration
PoE is an acronym for Power Over Ethernet. Power Over Ethernet is used to transmit electrical
power, to remote devices over standard Ethernet cable. It could for example be used for powering
IP telephones, wireless LAN access points and other equipment, where it would be difficult or
expensive to connect the equipment to main power supply.
Label Description
Reserved Power
determined by
There are three modes for configuring how the ports/PDs may reserve power.
1. Allocated mode: In this mode the user allocates the amount of power that each
port may reserve. The allocated/reserved power for each port/PD is specified in the
Maximum Power fields.
2. Class mode: In this mode each port automatically determines how much power to
reserve according to the class the connected PD belongs to, and reserves the power
accordingly. Four different port classes exist and one for 4, 7, 15.4 or 30 Watts.
In this mode the Maximum Power fields have no effect.
3. LLDP-MED mode: This mode is similar to the Class mode expect that each port
determine the amount power it reserves by exchanging PoE information using the LLDP
protocol and reserves power accordingly. If no LLDP information is available for a port,
the port will reserve power using the class mode
In this mode the Maximum Power fields have no effect
For all modes: If a port uses more power than the reserved power for the port, the port
is shut down.
