../../../_images/hubtool_ext3c_poe.png

The PoE tab shows the status of the Power over Ethernet system on the extension link. The PoE controller automatically manages power distribution between endpoints based on available sources and connected loads. For testing, diagnostics, and advanced applications, manual control and monitoring are available.
