• High-performance 24-port Gigabit Ethernet connectivity: Each port supports auto-negotiation for seamless compatibility with a wide range of devices, delivering full-duplex 1 Gbps performance to desktops, servers, printers, and IP cameras. The dense 24-port design maximizes space efficiency in office racks or on a desk, providing a straightforward path to a fast, dependable local area network. With energy-conscious hardware, the GS1900-24E keeps power use in check while maintaining consistent throughput for day-to-day operations and streaming workloads.
• Smart management for reliable networks: The GS1900-24E combines a user-friendly web GUI with CLI access, enabling administrators to configure VLANs, QoS, access control lists, and traffic policies without complexity. Features such as IGMP Snooping, traffic prioritization by 802.1p/class of service, and link aggregation (LACP) give you granular control over how data traverses your network. With SNMP support and remote management options, IT teams can monitor health, performance, and security from a centralized console, reducing troubleshooting time and improving uptime.
• Security and access control that protect your data: Built to minimize risk, the GS1900-24E includes security features like 802.1X port-based authentication, DHCP snooping, IP source guard, and ARP inspection. These controls help prevent unauthorized devices from connecting to the network and reduce the likelihood of attacks such as MAC spoofing and rogue DHCP servers. Layer 2 isolation through VLANs and secure management access contribute to safer guest networks and more predictable traffic for vital business applications.
• Scalability and reliability for growing deployments: With support for link aggregation (LACP) to combine multiple ports into higher-bandwidth uplinks, the GS1900-24E provides resilience and throughput for expanding workloads. Its robust Layer 2 feature set, including storm control and multicast filtering, helps maintain performance under heavy traffic while preserving service levels for critical apps. The practical, non-blocking design makes it an excellent fit for small offices, retail environments, or branch locations where dependable connectivity is essential.
• Compact, efficient design with quiet operation: The GS1900-24E is engineered to fit into diverse environments—whether mounted in a rack, placed on a shelf, or tucked into a small equipment cabinet. The chassis emphasizes quiet operation and solid build quality, delivering durable, long-term performance with a favorable total cost of ownership. Energy-saving features, plus efficient cooling and heat dissipation, keep the device running cool and reliable without unnecessary noise or power drain.

how to install ZYXEL GS1900-24E

• Unpack the switch and verify all ports and power connections are intact. Place the device on a suitable surface or mount it in a rack if needed, ensuring adequate ventilation around the chassis.
• Connect the switch to your network by plugging your uplink device (such as a router or core switch) into one or more ports using Cat5e/Cat6 cabling. For redundancy and higher throughput, configure a Link Aggregation group by combining multiple ports with LACP if your uplink device supports it.
• Power on the switch and connect a management workstation. Access the web-based management interface using the default IP address provided in the user manual, or set a static management IP on the PC and discover the switch through network scanning. Follow the on-screen wizard or navigate to the VLAN, QoS, and security sections to begin configuration.
• Set up VLANs to segment traffic by department, device type, or guest vs. corporate networks. Apply 802.1Q tagging where required, and configure appropriate port assignments so devices connect to the correct network segments. Enable QoS for latency-sensitive applications such as voice and video, and define traffic classes to prioritize critical traffic.
• Implement security policies: enable 802.1X authentication for wired access, activate DHCP snooping and IP source guard to mitigate rogue devices, and configure ARP inspection to prevent spoofing. Save your configuration and monitor port activity via the management interface to verify that traffic is flowing as intended and that security policies are enforced across the network.

Frequently asked questions

• What is the ZyXEL GS1900-24E best used for? The GS1900-24E is ideal for small to mid-sized business networks that require reliable, scalable Gigabit connectivity with robust Layer 2 features and easy management. It supports VLANs, QoS, and security controls to optimize performance and protect critical applications.
• Does the GS1900-24E support PoE? The GS1900-24E is a non-PoE variant in the GS1900 family. For PoE capabilities, consider other models within the GS1900 lineup such as the GS1900-8HP, which provides PoE support for powering access points or IP cameras.
• How do I manage this switch? You can manage it through a web-based GUI for most tasks, plus CLI access for advanced configurations. It also supports SNMP for centralized monitoring and integration with network management systems.
• Can I aggregate links for higher bandwidth? Yes. The GS1900-24E supports Link Aggregation (LACP) to combine multiple ports into a single, higher-bandwidth uplink, improving throughput and providing redundancy in the event of a port or link failure.
• Is the GS1900-24E suitable for guest networks? Yes. You can create separate VLANs for guest traffic, apply access controls, and manage bandwidth to ensure guest activity does not impact your corporate network.
• What kind of security features does it include? It includes 802.1X authentication, DHCP snooping, IP source guard, and ARP inspection to help protect against unauthorized devices and common network threats.
