D-Link PD-Alive Feature
for Powered Devices on Surveillance Networks

The PD-Alive feature is ideal for IP surveillance networks, as it will automatically check to see if powered devices (PDs) connected to PoE ports are currently active or not.

It can actively reset PDs to help reconnect them to the network, wake them up, or reset devices due to network connectivity problems.



IT network administrators set the poll (or ping) interval time, retry count, waiting time, and action.


The switch follows the protocol and pings PDs connected to PoE ports.


When inactivity is detected, the switch will reset the PD, notify a specified network administrator, or both based on the specific action.
