Advanced smart managed switching to minimise wasteful overpowering and help your business save money and time whilst powering more devices. Perfect for SMBs, these smart managed switches are rich in L2 features and provide 375 watts over Ethernet for reliable networking. Zyxel's One Network (ZON) provides a free tool to simplify configuration, management and troubleshooting, allowing you to focus on business priorities. Zyxel's networking equipment includes in-built awareness of other Zyxel units, enabling one-click remote factory resets and power cycling through Smart Connect. The web-based interface provides access to L2 features such as LACP, advanced QoS, VLAN, ACL and multicast IGMP snooping without complex command-line knowledge. Consumption mode delivers only the actual power required for improved efficiency and better ROI. The in-built smart fan automatically adjusts speed based on device temperature, enabling silent and reliable operation ideal for office environments. Easily maintain your network with the free Zyxel One Network tool. Install, configure and discover switches, WLAN and gateways with one-click. The GS1920 series provides multiple Gigabit copper and fibre ports for flexible connectivity and network growth.
