4.16.7 PD Alive-check
NS3502-8P-2S PoE switch can be configured to monitor connected PD’s status in real-time via ping
action. Once the PD stops working and without response, NS3502-8P-2S is going to restart PoE port
power, and bring the PD back to work. It will greatly enhance the reliability and reduces administrator
management burden.
This page provides you how to configure PD Alive Check. The screen in Figure 4-16-8 appears.
