according to the ports priority. If two ports have the same priority the port with the highest port number
is shut down.
2. Reserved Power: In this mode the ports are shut down when total reserved powered exceeds the
amount of power that the power supply can deliver. In this mode the port power is not turned on if the
PD
requests more power than available from the power supply.
PoE Power Supply Configuration
Primary Power Supply (W)
Some switches support having two PoE power supplies. One is used as primary power source, and
one as backup power source. If the switch doesn't support backup power supply only the primary power
supply settings will be shown. In case that the primary power source fails the backup power source will
take over. For being able to determine the amount of power the
PD
may use, it must be defined what
amount of power the primary and backup power sources can deliver.
The valid values in this field is range from 0 to 2000, however, the valid range of power supply is up to
your product specification.
Check the power budget of your switch and type the correct number here.
PoE
Port
Configuration
Port
This is the logical port number for this row.
Ports that are not PoE-capable are grayed out and thus impossible to configure PoE for.
PoE
Mode
The PoE Mode represents the PoE operating mode for the port.
Disabled: PoE disabled for the port.
PoE: Enables PoE IEEE 802.3af (Class 4 PDs limited to 15.4W)
PoE+: Enables PoE+ IEEE 802.3at (Class 4 PDs limited to 30W)
Priority
The Priority represents the ports priority. There are three levels of power priority named Low, High and
Critical.
The priority is used in the case where the remote devices requires more power than the power supply
can deliver. In this case the port with the lowest priority will be turn off starting from the port with the
highest port number.
Maximum
Power
The Maximum Power value contains a numerical value that indicates the maximum power in watts that
can be delivered to a remote device.
The maximum allowed value is 30 W.
