Digital Input and Digital Output for External Alarm
The Industrial Managed PoE+ Switch supports Digital Input and Digital Output on its upper panel. The external alarm enables
users to use Digital Input to detect external device's status (such as door intrusion detector), and send event alarm to the
administrators. The Digital Output could be used to alarm the administrators if the Industrial Managed PoE+ Switch port is
link-down, link-up or power-dead.
Intelligent Powered Device Alive Check
The Industrial Managed PoE Switch can be configured to monitor connected PD (powered device) status in real-time via ping
action. Once the PD stops working and responding, the Industrial Managed PoE Switch will recycle 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 reduce administrator management burden.
