Wanglink P O E switch test. specialized QC manager is testing the PCB board one by one before assembly, making sure all functions are running correctly. strict quality control is the vital principal for Wanglink. could you let me know how you test the PCB board and how to improve the quality? looking forward to getting your professional insight. comments please.
The PoE switch can force the port 1-8 transmission rate to be reduced to 10mbps through the DIP switch, and then this will be able to transmit a maximum distance of 250m through the existing twisted pair.At the same time, the port 1-8 are in a state of mutual network isolation, but they can communicate with the uplink ports (9-10) respectively.It can effectively isolate the conflict domain and broadcast domain, reduce the generation of broadcast storms, and improve the efficiency of network communication. It is an ideal choice for video surveillance networking in hotels, shops, supermarkets, family homes and small and medium-sized enterprises.
