2.3.6 Alive Check
The FGSW 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 FGSW 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.
