Configuring the PSE

ONFIGURATION
The whole PoE system is powered by the PoE power, which includes external PoE
power and internal PoE power.
n
The support for the PoE power type varies with devices.
PSE
■
PSE is a card or subcard. PSE manages its own PoE interfaces independently. PSE
examines the Ethernet cables connected to PoE interfaces, searches for the
devices, classifies them, and supplies power to them. When detecting a PD is
unplugged, the PSE stops supplying the power to the PD.
An Ethernet interface with the PoE capability is called PoE interface. Currently, a
PoE interface can be an FE or GE interface.
c
CAUTION: After you uninstall the PSE card using the remove command, the card
does not stop supplying power to the PD until the card is unplugged. For details of
the remove command, refer to
PD
■
A PD is a device accepting power from the PSE. There are standard PDs and
nonstandard PDs. A standard PD refers to the one that complies with IEEE 802.3af.
The PD that is being powered by the PSE can be connected to other power supply
unit for redundancy backup.
The protocol specification related to PoE is IEEE 802.3af.

CAUTION:
When the PoE power or PSE fails, you cannot configure PoE.
■
Turning off of the PoE power during the startup of the device might result in
■
the failure to restore the PoE configuration.
