The GSW 802.3at PoE+ Switch series can be configured to monitor connected PD's
status in realtime via traffic detection. Once there is no traffic at interval time, the
GSW 802.3at PoE+ Switch series is going to restart PoE port power, and bring the
PD back to work. It will greatly enhance the reliability and reduce administrator
management burden.
