Industrial-grade 4-port optical and 4-port Ethernet PoE switch

POE Management Function

Power Supply Power Configuration

Power can be manually and automatically allocated, and the total output power can be limited

Port modules can be selected, divided into PoE (15.4W) and PoE+ (30W);

Set the priority level of ports to consider the priority order of devices;

Compliant with IEEE802.3at/af standards;

Power Supply Time Schedule

Power output and power off can be set arbitrarily from Monday to Sunday at any time;

Power supply plans can be set for any port

Automatic Detection of Powered Devices

Monitor and detect powered devices during operation, and restart power management if a fault or abnormality occurs

The number of restarts can be set to resolve situations such as remote device freezes or crashes as much as possible

The restart delay time can be set to facilitate remote device maintenance and protect the device from being burnt out
