Ports 1 to 16 support IEEE802.3at/af PoE. This function allows for power supply of up to 30 W through
each port and 250W in total through the Switching Hub.
PoE power supply function operation overview
2.2 PoE power supply function
Port LEDs (right) 1 to 16
Green Light: Supplying power normally.
Orange Blink: Overload caused by a single port. (Requested power is exceeding 30 W. *1) or
total power supplied by the Switching Hub.
Off: Not supplying power or no PoE-powered device connected.
PoE LIM. LED (PoE limit)
For silent fan control high-speed (High)* For factory default, or low-speed (Low2)
Off:
Supplying power in the range from 0 to 235 W.
Green Light: Supplying power in the range from 235 to 250 W.
Orange Blink: A single port's power supply is exceeding the upper limit, or the total power
supply of the Switching Hub is exceeding 250 W.
For silent fan control low-speed (Low1), or min-speed (Min)
Off:
Supplying power in the range from 0 to 170 W.
Green Light: Supplying power in the range from 170 to 185 W.
Orange Blink: A single port's power supply is exceeding the upper limit, or the total power
supply of the Switching Hub is exceeding 185 W.
*1 When configured IEEE802.3at (factory default). Exceeds 15.4 W when configured IEEE802.3af.
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.
Power supply while the PoE LIM. LED is blinking orange
(overload caused by the total power supplied by the Switching Hub)
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.
(If the requested power supply for the device overall is exceeded, then the power supply to
a port with a higher port number will be stopped first.)
