Built-in Unique PoE Functions for Surveillance Management
As a managed PoE Switch for surveillance network, the GS-5220-8P2T2S features
the following intelligent PoE management functions:
■PoESchedule
■PDAliveCheck
■ScheduledPowerRecycling
■SMTP/SNMPTrapEventAlert
PoE Schedule for Energy Saving
Besides being used for IP surveillance, the GS-5220-8P2T2S 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-5220-8P2T2S 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.
Total Consumption of 36 watts/hr Save 24 watts/hr during off-business hours
Total Saved = 10800watts/month

Intelligent Powered Device Alive Check
TheGS-5220-8P2T2ScanbeconguredtomonitoraconnectedPDstatus inreal
time via ping action. Once the PD stops working and it is without response, the
GS-5220-8P2T2S 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.
