Built-in Unique PoE Functions for Powered Devices Management
As it is the managed PoE switch for surveillance, wireless and VoIP networks, the
GS-4210-8P2S features the following special PoE management functions:
■PDAliveCheck
■ScheduledPowerRecycling
■PoESchedule
■PoEUsageMonitoring
■PoEExtension
Intelligent Powered Device Alive-Check
TheGS-4210-8P2ScanbeconguredtomonitorconnectedPD(powereddevice)
status in real time via ping action. Once the PD stops working and responding, the
GS-4210-8P2S 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 the administrator’s management burden.
