Section 4
PoE Max
On: When the remaining system power is less than or equal to 7.5 watt, this LED
will light, and no more power will be provided to additional PoE devices.
Off: When the system has power over 7.5 watt.
For example: When the total power consumption is 25 watt, the PoE Max LED
will light because the remaining power is less than 7.5 watt. If another PoE device
is connected, the system will not provide power to the additional PoE device.
Priority: This function protects the Switch when the system power is over loaded.
The Switch will disable PoE function to the lower priority PoE ports to maintain the
power requirement of the PoE port with a higher priority. When the shared power
resource is over 30 watt, the system will automatically distribute power according
to the priority status of each port. The lower port number has higher priority than
the higher port number, Port 1 > Port 2 > Port 3 > Port 4.
For example: Port 2 is using 7 watt and Port 3 is using 15.4 watt for a combined
usage of 22.4 watt. If you connect an additional PoE device to Port 1 with 15.4
watt requirement, the shared power resource would be over 30 watt and the priority
function would be activated. Since Port 1 has the highest priority, it will have 15.4
watt, Port 2 will have 7 watt, and the system will cut off power to Port 3 due to
overcurrent.
