Built-in Unique PoE Functions for Powered Devices Management
As it is the managed PoE switch for surveillance, wireless and VoIP networks, the GS-5220 Ultra PoE & PoE+ Series features
the following special PoE management functions:

PD alive check

Scheduled power recycling

PoE schedule

Intelligent Powered Device Alive Check
The GS-5220 Ultra PoE & PoE+ Series can be configured to monitor connected PD (powered device) status in real time via ping
action. Once the PD stops working and responding, the GS-5220 Ultra PoE & PoE+ Series 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.
Scheduled Power Recycling
The GS-5220 Ultra PoE & PoE+ Series allows each of the connected PoE IP cameras or PoE wireless access points to reboot
at a specified time each week. Therefore, it will reduce the chance of IP camera or AP crash resulting from buffer overflow.
