Built-in Unique PoE Functions for Powered Devices Management
As it is the managed PoE switch for surveillance, wireless and VoIP networks, the
WGS-4215-8P2S features the following special PoE management functions:
• PD alive check
• Scheduled power recycling
• PoE schedule
• PoE usage monitoring
Intelligent Powered Device Alive Check
The WGS-4215-8P2S can be configured to monitor connected PD (Powered Device)
status in real time via ping action. Once the PD stops working and responding, the
WGS-4215-8P2S 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 and reducing administrator management burden.
Scheduled Power Recycling
The WGS-4215-8P2S allows each of the connected PoE IP cameras or PoE wireless
access points to reboot at a specific time each week. Therefore, it will reduce the
chanceofIPcameraorAPcrashresultingfrombufferoverow.
