WGS-804HPT

Intelligent Powered Device Alive Check
The WGS-804HPT 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-804HPT 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-804HPT 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.
PoE Schedule for Energy Saving
Under the trend of energy saving worldwide and contributing to environmental
protection, the WGS-804HPT 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 or enterprises save power and budget. It also
increases security by powering off PDs that should not be in use during non-business
hours.
