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 fullls 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 oers 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 eort needed to initialize the network. Easy
deployment, smart management and solid security—the GS1920 Series is the best solution for
SMB networks.
Benets
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 and managing a network,
ZyXEL ONE Network is designed to simplify the conguration, 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

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
rmware image and conguration 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 ecient 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, lter and police all
trac between clients within the same subnet, creating an even higher degree of security.
