28-Port Managed Switch | 8-RJ45 Ethernet Ports, 20-SFP Fiber Ports

Description Technical Specification Key Features Resources & Downloads

VERSITRON’s 28 port managed switch feature 8 combo ports RJ-45 shielded connectors that support Auto-MDI/MDX and auto-negotiation, enabling seamless optimization and integration for various networking environments. Its 16 SFP slots can accommodate long-distance communications with improved security and high throughput needs. These slots are ideal for industrial facilities looking to leverage fiber optic connectivity options. Finally, its 4 1G/10G SFP slots support high-speed networking, offering unparalleled performance for backbone connections and data-intensive applications.

This 28-port gigabit switch has L2+ management capabilities with several sophisticated control options, including Telnet, Web, CLI, and SNMP management interfaces. These control options allow you to prioritize data flow, ensuring data-intensive applications, such as video conferencing and VOIP, receive uninterrupted bandwidth. This 28 port managed switch has impressive 128Gbps switching capacity and 95Mpps forwarding performance assure high bandwidth and low latency, thereby making it an ideal choice for data-intensive applications. Additionally, it supports jumbo frames up to 9.6K bytes, thereby enabling seamless data transmission.

VERSITRON’s 28 port gigabit switch supports multiple VLAN protocols, including MAC-based VLAN, IP-based VLAN, Protocol-based VLAN, Q-in-Q Configuration, and Port Configuration of Access. This enables you to segment the network into virtual LANs, creating isolated traffic flows for different functions, thereby enhancing the overall efficiency of the network. Advanced security features of this 28-port managed switch, including IEEE802.1x & MAC Address Authentication, Radius Service, Port Security, IP Source Protection, IP-MAC-Port Binding, ARP Inspection, ARP Packet Filtering, and Port Isolation, enables you to safeguard your switch against unauthorized access and threats, ensuring your data security.
