A PoE-enabled S3100 switch has the following features:
z
As the PSE, it supports the IEEE802.3af standard. It can also supply power to 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 switch can be upgraded online.
z
The switch provides statistics about power supplying on each port and the whole equipment, which
you can query through the display command.
z
The switch provides two modes (auto and manual) to manage the power feeding to ports in the
case of PSE power overload.
z
The switch provides over-temperature protection mechanism. Using this mechanism, the switch
disables the PoE feature on all ports when its internal temperature exceeds 65°C (149°F) for
self-protection, and restores the PoE feature on all its ports when the temperature drops below
60°C (140°F).
z
The switch 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 S3100 switch to supply power, the PDs need no external power
supply.
z
If a remote PD has an external power supply, the PoE-enabled S3100 switch and the external
power supply will backup each other for the PD.
z
Only the 100 Mbps Ethernet electrical ports of the PoE-enabled S3100 switch support the PoE
feature.
