Parameter description:
Power Over Ethernet Configuration

Reserved Power determined by :
There are three modes for configuring how the ports/ PDs may reserve power.
1. Allocated mode: In this mode the user allocates the amount of power that each port may
reserve. The allocated/reserved power for each port/
PD is specified in the Maximum Power
fields.
2. Class mode: In this mode each port automatically determines how much power to
reserve according to the class the connected
PD belongs to, and reserves the power
accordingly. Four different port classes exist and one for 4, 7, 15.4 or 30 Watts.
In this mode the Maximum Power fields have no effect.
3. LLDP-MED mode: This mode is similar to the Class mode expect that each port
determine the amount power it reserves by exchanging PoE information using
the
LLDP protocol and reserves power accordingly. If no LLDP information is available for a
port, the port will reserve power using the class mode
In this mode the Maximum Power fields have no effect
For all modes: If a port uses more power than the reserved power for the port, the port is
shut down.

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] :
To display watts for the primary power supply.
PoE Port Configuration

Port :
This is the logical port number for this row.

PoE Mode :
The PoE Mode represents the PoE operating mode for the port. Enable or Disable PoE.

PoE Schedule :
Disable or Select the PoE Schedule profile.

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
