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 GS1920-48 switch fulfills these expectations with support for 44 100/1000BASE-T copper ports + 4 Combo SFP Ports + 2 SFP Ports (50 Ports Total), as well as non-blocking performance to facilitate a greater number of network connections. The ZyXEL GS1920-48 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 GS1920-48 is the best solution for SMB networks. 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 GS1920-48 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. The GS1920-48 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 GS1920-48 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.

  • Smart managed switch with essential L2 features
  • 44x Gbe RJ-45, 4x Gbe combo (RJ-45/SFP) (50 Ports Total)
  • Reliable network availability with Loop Guard, IPSG, and CPU protection
