ZyXEL Smart Switch Simplifies Robust Network Management

Today's small and medium-sized businesses (SMBs) expect a higher level of performance from their networks-more connections to support diverse applications; fewer network disruptions; easier management and a greater degree of network security. The ZyXEL GS1920 Series of switches fulfills these expectations with support for 24/48 100/1000BASE-T PoE Plus or non-PoE copper ports; as well as non-blocking performance and high-power budget support to facilitate a greater number of network connections.

The ZyXEL GS1920 Series offers network protection features and comprehensive access management functions to establish a reliable and secure network environment. Easy deployment; smart management and solid security-the GS1920 Series is the best solution for SMB networks.

  • Smart managed switch with essential L2 features

Advanced Standard Compliance With Intelligent Power Function Support

ZyXEL GS1920 Series PoE switches support 802.3at PoE Plus standards; with a 375-watt high-power budget to meet the connectivity needs of additional powered devices like 802.11ac WLAN access points; VoIP phones and IP cameras. Not only do the GS1920 Series switch PoE models feature full PoE ports; they also employ intelligent technology. While set to Consumption Mode; switches can automatically detect the power consumption status of each powered device and supply only the amount of power required. This intelligent power allocation function minimizes wasteful overpowering of devices; thereby helping businesses save money; while enabling the PoE switch to power more devices.

Zyxel One Network Experience

Aiming for relieving our customers from repetitive operations of deploying andmanaging 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.

Robust Network Availability

Network disruptions are a frequent source of headaches for small to medium-sized businesses. Whether outages are caused by internal errors or outside attack; the ZyXEL GS1920 Series protects users from network disruptions and ensures uninterrupted connectivity through several key features. Loop Guard helps networks avoid service disruptions caused by switching loops; and IP Source Guard (IPSG) shields your network from MAC spoof and ARP spoof attacks. Additionally; attacks such as BPDU; ARP and IGMP can target network facilities. However; CPU protection guarantees that a network continues to operate; even while under attack. Furthermore; dual firmware image and configuration features improve network reliability and availability. These are just some of the ways the GS1920 Series switches guarantee headache-free network connectivity for SMBs.

Rigorous Access Protection To Secure The Network

The ZyXEL GS1920 Series provides efficient allocation of network resources while ensuring comprehensive access protection; along with simple and secure network control. Not only does the GS1920 Series support 802.1X authentication with RADIUS; but it can monitor; filter and police all traffic between clients within the same subnet; creating an even higher degree of security.
