Intelligent Powered Device Alive Check
The LRP-422CST can be configured to monitor connected PD (Powered Device) status in real time via ping action. Once the PD stops working and
responding, the LRP-422CST will resume the PoE port power and bring the PD back to work. It will greatly enhance the network reliability through the PoE
port resetting the PD’s power source and reducing administrator management burden.
