Versatility and flexibility for different needs

The complete Zyxel GS1900 Series has an essential portfolio of 8/10/16/24/48- port compact desktop and rackmount size with GbE connectivity. All models support multiple deployment methods to fulfill the needs for small offices and meeting room environments such as wall, under table or desktop mounting and rackmount options. It’s now quick and effortless to enjoy the high-speed business network applications without a hitch. Additionally, the GS1900-10HP/ 24/24HPv2/48/48HPv2 is equipped with 2 extra SFP slots to provide 100M and GbE speeds for long-distance deployments.

Experience whisper-silent operations

The GS1900 Series includes fanless and built-in smart fan models. The smart fan is designed to automatically adjust speeds based on the device temperature, offering near silence while the GS1900 Series is in operation. Ideal for your office environment no matter if it’s on the desktop or mounted on a rack.

Simple, intuitive wizard set up

For small businesses that want to manage their infrastructure in advance, the Zyxel GS1900 Series comes with a friendly built-in Web-based browser for simple configuration and management. Moreover, the friendly step-by-step intuitive wizard helps avoiding multiple complicated configuration pages for quick set up with few clicks in the matter of minutes. To guide the users from start-up, VLAN, Guest VLAN to QoS setting, the Zyxel Series offers four most common steps and combines them into a quick and easy setup wizard; which does not just save deployment time and efforts, but is also helpful especially for the non-IT staff.

Intelligence to power more devices (PoE models)

PoE models of GS1900 Series support IEEE 802.3at providing a maximum of 30 W per port features with default PoE consumption mode to deliver only the actual power required by your networked devices, reserves the rest and optimizes its power budget. That means a single switch can power more APs, IP cameras and VoIP phones, ensuring a better ROI for your business.

Web managed with advanced features

Designed to support advanced features like VLAN (for segregation of your public and private networks), enhanced Quality of Service (for better bandwidth management), IGMP Snooping, Link Aggregation (LAG), IPv6 and DoS prevention, this switch helps you segregate and prioritize traffic streams and keep up with your network as it grows.

Plug into the power of the Zyxel One Network
