A PoE-enabled device has the following features:
z
As the PSE, it supports the IEEE802.3af standard. It can also supply power to some PDs that do
not support the 802.3af standard.
z
It can deliver data and current simultaneously through data wires (1,2,3,6) of category-3/5 twisted
pairs.
z
The PSE processing software on the device can be upgraded online.
z
The device provides statistics about power supplying on each port and the whole equipment, which
you can query through the display command.
z
The device provides two modes (auto and manual) to manage the power feeding to ports in the
case of PSE power overload.
z
The device provides over-temperature protection mechanism. When the internal temperature of
the device exceeds the PoE protection temperature, the device disables the PoE feature on all
ports for self-protection.
z
The device supports the PoE profile feature, that is, different PoE policies can be set for different
user groups. These PoE policies are each saved in the corresponding PoE profile and applied to
ports of the user groups.
z
When you use the PoE-enabled device to supply power, the PDs need no external power supply.
z
If a remote PD has an external power supply, the PoE-enabled device and the external power
supply will backup each other for the PD.
z
Only the Ethernet electrical ports of the PoE-enabled device support the PoE feature.
