Minimise wasteful overpowering of devices and help your business save money and time whilst powering more devices with the GS1920 series.
Perfect for SMBs these smart managed switches are rich in L2 features and provide 375Watts over
Ethernet providing reliant and future-proof networking.
Zyxel's One Network (ZON) provides a free and easy-to-use tool to simplify configuration, management and troubleshooting of the switch allowing you to focus on your business priorities.
