GS-4210-24P2S

Intelligent Powered Device Alive Check
The GS-4210-24P2S 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-
4210-24P2S 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-4210-24P2S allows each of the connected PoE IP cameras or PoE wireless
access points to reboot at a specic time each week. Therefore, it will reduce the chance
of IP camera or AP crash resulting from buffer overow.
PoE Schedule for Energy Saving
Under the trend of energy saving worldwide and contributing to environmental protection,
the GS-4210-24P2S 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 specied time intervals and it is a powerful
function to help SMBs or enterprises save power and money. It also increases security
by powering off PDs that should not be in use during non-business hours.
