Power supply function
Ports 1 to 24 support the IEEE802.3 at/af compatible power supply function.
Maximum power supply: 30W per port, 185W in total
Power supply method
Alternative A (Using 1,2,3,6 pin)
Silent fan control
The fan rpm can be set in accordance with the usage environments.
If the fan rpm are set, the maximum power supply will be
automatically restricted. If the fan rpm (Fan Speed) are set to Low1,
or Min, the device’s overall maximum power supply (Power Budget)
will be automatically restricted, and it can be used with the fan noise
reduced.
