LABEL DESCRIPTION
PoE Mode Select the power management mode you want the Switch to use.
•
Classification - 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.
• Consumption - 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.
Port This is the port index number.
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.
PD Priority This field is only available on the PWR model but not available for the Gigabit or mini-
GBIC ports.
When the total power requested by the PDs exceeds the total PoE power budget on
the Switch, you can set the PD priority to allow the Switch to provide power to ports
with higher priority.
Select
Critical to give the highest PD priority on the port.
Select High to set the Switch to assign the remaining power to the port after all critical
priority ports are served.
Select
Low to set the Switch to assign the remaining power to the port after all critical
and high priority ports are served.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click Cancel to begin configuring this screen afresh.
