PoE standards

Power over Ethernet (PoE) supplies power and data over a single Ethernet cable connection. This reduces installation cost and effort for locations without available power lines. 

There are 3 common PoE standards:

• 802.3af: PoE delivers up to 15 Watt per port
• 802.3at: PoE+ delivers up to 30 Watt per port
• 802.3bt: PoE++ delivers up to 90 Watt per port

The PoE standard supported by a Plasma Cloud PoE equipment (PSE) depends on the specific model. Refer to the comparison table below for details.

Compatible PoE devices

The graphic below shows common examples for PoE consuming devices and their required PoE standards. Check your specific device to learn about its power / PoE standard requirements.

Plasma Cloud Switches intelligently identify the PoE standard required by each connected device and supply the corresponding power level, safeguarding against power overdraw.

The AP-per-Switch estimate assumes each AP is drawing its maximum rated power. In practice, if APs operate under typical or lower loads, additional devices may be supported beyond the stated capacity.
