4.16.7 PoE Alive Check Configuration
The NS3552-8P-2S PoE Switch can be configured to monitor connected PD’s status in real time via ping action. Once the PD
stops working and is without response, the NS3552-8P-2S PoE Switch 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.
 PD Ping Alive Check Configuration

Figure 4-16-8: PD Alive Check Configuration Screenshot
The page includes the following fields:
Object Description
• Mode Allows user to enable or disable per port PD Alive Check function. As default value all
ports are disabled.
• Ping PD IP Address This column allows user to set PoE device IP address here for system making ping to
the PoE device. Please be noted that the PD’s IP address must be set to the same
network segment as the NS3552-8P-2S PoE Switch.
• Interval Time (10~300s)
This column allows user to set how long system should issue a ping request to PD for
detecting PD whether it is alive or dead. Interval time range is from 10 seconds to 300
seconds.
• Retry Count (1~5)
This column allows user to set how many times system retries ping to PD. For
example, if we set count 2, the meaning is that if system retries ping to the PD and the
PD doesn’t response continuously, the PoE port will be reset.
• Action Allows user to set which action will be applied if the PD is without any response. The
NS3552-8P-2S PoE Switch offers 3 actions as follows:
 PD Reboot: It means system will reset the PoE port that is connected to the
PD.
