Intelligent Powered Device Alive Check
The GS-5220-8UP2T2X can be configured to monitor a connected PD status in
real time via ping action. Once the PD stops working and it is without response,
the GS-5220-8UP2T2X 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, thus reducing administrator management burden.

PoE Schedule for Energy Saving
Besides being used for IP surveillance, the GS-5220-8UP2T2X is certainly
applicable to build any PoE network including VoIP and wireless LAN. Under the
trend of energy saving worldwide and contributing to the environmental protection
on the Earth, the GS-5220-8UP2T2X can effectively control the power supply
besides its capability of giving high watts power. The “PoE schedule” function helps
you to enable or disable PoE power feeding for each PoE port during specified
time intervals and it is a powerful function to help SMBs and enterprises save
energy and budget.
