Poe Power Supply Function - Panasonic GA-ML4TPoE+ Series Installation Manual

2.2 PoE power supply function

 PoE power supply function operation overview
Ports 1 to 4 support IEEE802.3at/af PoE. This function allows for power supply of up to 30 W through
each port and 62W in total through the Switching Hub.
Port LEDs (right) 1 to 4
Green Light: Supplying power normally.
Orange Blink: Overload caused by a single port. (Requested power is exceeding 30 W. *1) or
Off:
PoE LIM. LED (PoE limit)
Off:
Green Light: Supplying power in the range from 47 to 62 W.
Orange Blink: A single port's power supply is exceeding the upper limit, or the total power
*1 When configured IEEE802.3at (factory default). Exceeds 15.4 W when configured IEEE802.3af.
 Power supply while the PoE LIM. LED is blinking orange
(overload caused by the total power supplied by the Switching Hub)
When the requested power supply for the Switching Hub is exceeded and it gets overloaded, the
power supply to the low priority ports is stopped, and the port LEDs (right) of the ports whose power
supply have been stopped blink orange.
The priority settings for the power supply can be set and changed from the console, etc.
* For configuration and management method, please see the PDF version Operating
Instructions in CD-ROM.
 Power supply while the overload is caused by a single port
When the power supply which is requested exceeds 30 W via a single port and the port LED (right)
blinks orange, and the power supply is stopped.
Unplug the port cable which is blinking orange, and check the PoE receiving equipment's specifications.
Caution: 1) Some PoE-powered devices may have a large difference in power consumption between
their maximum power use condition and normal condition. Carefully configure them so
that the upper limit of power supply will not be exceeded.
2) If you do not set a priority for power supply or if the same priority is given, note that the
power supply priority is assigned to the ports in ascending order of the port numbers.
(When the requested power supply exceeds 62W, power supply to a port with a higher
port number will be stopped first.)
