Zyxel One Network Experience

Aiming for relieving our customers from repetitive operations of deploying and managing a network; ZyXEL ONE Network is designed to simplify the configuration; management; and troubleshooting; allowing our customers to focus on the business priorities. ZyXEL ONE Network presents an easy-to-use tool; ZyXEL ONE Network Utility (ZON Utility); to realize speed network setup. ZyXEL Smart Connect allows ZyXEL networking equipment to be aware and recognize each other and further facilitating the network maintenance via one-click remote functions such as factory reset or power cycling. ZyXEL ONE Network redefines the network integration across multiple networking products from switch to Wi-Fi AP and to Gateway.

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.

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.
