Product Description

Zyxel GS1900-48HP, 48-port L2 Smart Switch, 170 Watt rackmount

The ZyXEL GS1900-48HP is a smart managed switch with 48 Gigabit ports to provide network connectivity and flexibility to a business network. With IPv6 support, this ZyXEL GS1900-48HP 48-Port Smart Managed Gigabit Switch has been designed with a host of useful features and advanced performances that empower your networks with speed and security as well as silent operation in your office environments. The ZyXEL GS1900-48HP switch also features two SFP ports for Gigabit uplinks and network expansion and 802.3at PoE+ for powering external PoE devices up to 30W.

Versatility And Flexibility

The ZyXEL GS1900-48HP 48-Port Smart Managed Gigabit Switch is Rackmountable for supporting multiple deployment methods to fulfil the needs for small offices and meeting room environments such as under a table, on a desktop or within a server rack or data cabinet. It's now quick and effortless to enjoy the high-speed business network applications without a hitch.

Simple, Intuitive Wizard Set Up

For small businesses that want to manage their infrastructure in advance, the ZyXEL GS1900-48HP switch 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 complex steps have been combined into four quick individual steps; 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 GS1900-48HP switch 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 ZyXEL GS1900-48HP switch 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 GS1900-48HP switch 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 utilisation 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

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