Simple, Fast and Smart Managed Switches for Small Business Connectivity
The ZyXEL GS1900 Series of 8/16/24/48-port GbE Smart Managed Switch with Gigabit speed and essential managing functions bring your business network more fexibility and connectivity. The 1900 Series consists of eight (8) models—the GS1900-8, GS1900-8HP, GS1900-16, GS1900-24E, GS1900-24, GS1900-24HP, GS1900-48 and GS1900-48HP. Providing GbE switches with powersaving functions, fanless design and full IPv6 support ensure your network to be ready for future expansions. In addition, the PoE models GS1900-8HP/24HP/48HP Gigabit switch complies with the IEEE 802.3at Power over Ethernet (PoE) Plus standard. The complete GS1900 Series has been designed with useful features and advanced performances that empower your networks with speed and security as well as silent operation in your office environments.

Avoiding network errors with easy management
The ZyXEL GS1900 Series is equipped with advanced management features to make the network stable and secure: loop protection that prevents network flooding, dual images to provide a backup FW if one crashes and storm control to ensure network efficiency, friendly on/off DoS with simple click to enable/disable instead of several setup pages, while SSL ensures the management frames are well encrypted when the device is accessed. The GS1900 Series provides network error prevention features and integrated network security for reduced risk and improved data streaming.

Energy saving for IEEE 802.3az
As operating overheads such as electric bills increase constantly due to the arising green awareness, businesses have to avoid unnecessary energy waste. The built-in IEEE 802.3az Energy Efficient Ethernet (EEE) and more ZyXEL innovative green features of ZyXEL GS1900 Series can reduce energy consumption of Ethernet devices through multiple intelligent ways.

- Traffic detection—Energy Efficient Ethernet (EEE) compliance
The IEEE 802.3az Energy Efficient Ethernet (EEE) feature automatically detects network traffic and adjusts power consumption dynamically, as such the switch can reduce power consumption during low link utilization periods.

- Inactive link detection
The inactive link detection function automatically reduces power usage when inactive links or devices are detected. The ZyXEL GS1900 Series can adjust power consumption according to the link status and number of the active network devices.

- Cable length detection
This green feature enables the switch to automatically detect the length of connected Ethernet cables and adjust power usage accordingly. The shorter the cable length, the less power it consumes.

Intelligence to power more devices (GS1900-8HP/24HP/48HP)
ZyXEL’s Intelligent PoE feature provides two PoE supply modes: classification mode and consumption mode. Especially in consumption mode, the GS1900-8HP/24HP/48HP reserves the actual required power automatically, and you can set power feeding priorities on different ports to get the optimized use of power resource. This capability increases the number of devices connected and deliver a better ROI for the business. In addition, the GS1900-8HP supports the IEEE 802.3at standard on all 8 ports, providing a maximum of 30 watts per port, total 70 watts. Besides, the GS1900-24HP and 48HP both provide 170 watts of total budget power for devices with higher power requirements such as IP phones, IP cameras and wireless access points.
