Power Management Mode
There are 2 modes for configuring when to shut down the ports:
1.
Actual Consumption:
In this mode, the ports are shut down when the actual power consumption for
all ports exceeds the amount of power that the power supply can deliver or if the actual power
consumption for a given port exceeds the reserved power for that port. The ports are shut down
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 a backup power source. If the switch doesn't support a backup power supply, only the primary
power supply settings will be shown. In case the primary power source fails, the backup power source
will take over. To be able to determine the amount of power the
PD
may use, the amount of power the
primary and backup power sources can deliver must be defined.
The valid values in this field range from 0 to 2000; however, the valid range of the 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 for PoE.
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 15.4 W).
PoE+
: Enables PoE+ IEEE 802.3at (Class 4 PDs limited to 30 W).
Priority
The
Priority
represents the ports priority. There are three levels of power priority: 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 turned off starting from the port with the
highest port number.
