Product Features
Technical Overview
This switch provides 24 Gigabit Ethernet ports that auto-negotiate to 10/100/1000 Mbps speeds, ensuring compatibility with a wide range of devices from legacy equipment to modern high-speed endpoints. All RJ-45 ports support Power over Ethernet, eliminating the need for separate power adapters for connected PoE devices. The two shared SFP slots accept mini-GBIC transceivers for connecting to fiber optic cabling, enabling network spans beyond the 100-meter limit of copper Ethernet.
Operating at Layer 2 of the OSI model, the switch performs basic switching functions including MAC address learning, frame forwarding, and loop prevention through spanning tree. While not manageable via a web interface or CLI, it includes essential features like IGMP snooping for efficient multicast traffic handling and port mirroring for network monitoring. The internal power supply delivers consistent voltage to all ports, supporting PoE devices without external power injectors.
