A PoE-enabled Switch 4210 has the following features:
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.
It can deliver data and current simultaneously through data wires (1,2,3,6) of
■
The PSE processing software on the switch can be upgraded online.
The switch provides statistics about power supplying on each port and the
■
whole equipment, which you can query through the display command.
The switch provides two modes (auto and manual) to manage the power
■
feeding to ports in the case of PSE power overload.
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).
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.
n
When you use the PoE-enabled Switch 4210 to supply power, the PDs need no
■
external power supply.
If a remote PD has an external power supply, the PoE-enabled Switch 4210 and
■
the external power supply will backup each other for the PD.
Only the Ethernet electrical ports of the PoE-enabled Switch 4210 support the
■
PoE feature.
