Product Features
Technical Overview
This switch operates at Gigabit Ethernet speeds across all ports, supporting network technologies of 10/100/1000Base-TX and 1000Base-X for high-speed data transfer. The 26 Gigabit Ethernet ports handle standard twisted pair connections, while the four SFP slots allow for fiber optic uplinks or additional Gigabit Ethernet expansion via SFP modules. The shared SFP slot design optimizes port utilization, and the modular expansion capability supports future network upgrades without replacing the entire switch.
Layer 3 switching enables advanced routing protocols, VLAN support, and quality of service (QoS) features, improving network performance and management granularity. The manageable interface provides full control over configuration, monitoring, and security settings through a web-based or command-line interface. Power is supplied via an internal power supply, with no support for redundant power supplies, but the low power consumption of 36.90 watts contributes to energy efficiency in deployment.
