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. To create a one-network experience, the GS1920 Series features inter-device discovery and reset, which along with the ZON utility, reduces the time and effort needed to initialize the network. Easy deployment, smart management and solid security—the GS1920 Series is the best solution for SMB networks.

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.

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. Intrusion Lock detects connection status and ensures port security. 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.
