Zyxel GS1920-24 Технические характеристики онлайн
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 ful lls 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 o ers 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 ideal 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  rmware image and con guration features improve network
reliability and availability. These are just some of the ways the GS1920 Series switches guarantee
headache-free network connectivity for SMBs.
