65 watts max.
Class 4 PD@25-watt
2 units
Class 3 PD@15-watt
4 units
Class 2 PD@7-watt

Note:
1. The PoE Output Budget means the 4-port PD aggregated power output. The aggregated power consumption will be below 65
watts if with
IEEE 802.3bt PoE++
PSE.
2. If the PoE output, whose power source is
IEEE 802.3at PoE+
, is more than 25 watts, the device will be shut down.
