LABEL DESC RIPTIO N
PoE Mode Select the power management mode you want the Switch to use.
•
C la ssific a tio n
- Select this if you want the Switch to reserve the Max Power (mW) to each PD
according to the priority level. If the total power supply runs out, PDs with lower priority do not
get power to function.
•
C o nsum ptio n
- Select this if you want the Switch to manage the total power supply so that
each connected PD gets a resource. However, the power allocated by the Switch may be
less than the Max Power (mW) of the PD. PDs with higher priority also get more power than
those with lower priority levels.
Pre-Allocate Select this to have the Switch pre-allocate power to each port based on the classification of the
PD device.
Dual Detection Select this to have the Switch run another detecting procedure between the detection and
classification stages. This helps check if the power interface (PI) range of the connected PD is
within the IEEE 802.3AF/AT standard range and ensures it is an IEEE PD.
Power Up
Sequence
Delay Select this to allow PoE ports to be powered up one-by-one randomly or clear to allow them all to
be powered up at the same time.
Port This is the port index number.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
PD Select this to provide power to a PD connected to the port.
If left unchecked, the PD connected to the port cannot receive power from the Switch.
