4. Power over Ethernet Budget
The following table lists how many PoE devices can be powered by the IPOE-
E302 over a distance of under 1m:
Power Source
PoE Output
Budget*
Max. Number of PDs supported
IEEE 802.3bt PoE++
PSE (Type 4)
90 watts max.
Class 4 PD@25.5 watts 2 units
Class 3 PD@12.9 watts 2 units
Class 2 PD@6.5 watts 2 units
Class 1 PD@3.8 watts 2 units
IEEE 802.3bt PoE++
PSE (Type 3)
60 watts max.
Class 4 PD@25.5 watts 1 unit
Class 3 PD@12.9 watts 2 units
Class 2 PD@6.5 watts 2 units
Class 1 PD@3.8 watts 2 units
IEEE 802.3at PoE+
PSE (Type 2)
30 watts max.
Class 4 PD@25.5 watts 1 unit
Class 3 PD@12.9 watts 2 units
Class 2 PD@6.5 watts 2 units
Class 1 PD@3.8 watts 2 units
Remarks:
1. The PoE output budget means the aggregated power output of the 2 PSE
ports.
2. The aggregated power consumption will be below 60 watts if with PoE+ PSE.
