DESCRIPTION
Sets how the Switch provides power to a connected
PD at power-up.
802.3af
over Ethernet standard to supply power to the
connected PDs during power-up.
legacy
connected PDs that require high inrush currents at
power-up. Inrush current is the maximum,
instantaneous input current drawn by the PD when
first turned on.
pre-802.3at
port according to the IEEE 802.3af standard, and then
switches to support the IEEE 802.3at standard within 75
milliseconds after a PD is connected to the port.
Select this option if the Switch is performing 2-event
Layer-1 classification (PoE+ hardware classification) or
the connected PD is NOT performing Layer 2 power
classification using Link Layer Discovery Protocol
(LLDP).
802.3at
Power over Ethernet standard and can supply power
of up to 30W per Ethernet port. IEEE 802.3at is also
known as PoE+ or PoE Plus. An IEEE 802.3at
compatible device is referred to as Type 2. Power
Class 4 (High Power) can only be used by Type 2
devices. If the connected PD requires a Class 4
current when it is turned on, it will be powered up in
this mode.
802.3bt
standard and can supply power of up to 60W per
Ethernet port to the connected PDs at power-up.
Sets the PD priority on a port to allow the Switch to
allocate power to higher priority ports when the
remaining power is less than the consumed power.
critical
Note: Available for non-full power models only.
Specifies a pre-defined schedule to control when the
Switch enables PoE to provide power on the specified
port(s).
Removes all the applied schedule(s) from the
specified port(s).
Removes a specific schedule from the specified
port(s).
