It bridges Gigabit management access with 10 Gigabit SFP+ uplinks, enabling IT teams to deploy fiber-based network segments in offices, labs, or distributed locations where fanless operation and desk-friendly form factors are essential.\u003c\/p\u003e\n\u003cp\u003eBuilt on the 98DX3236 switch chip with 512MB RAM and dual-core ARM architecture, this device handles 41Gbps of non-blocking throughput with forwarding rates up to 61Mpps. The dual boot system allows network administrators to run full RouterOS for VLAN, routing, and firewall capabilities, or switch to lightweight SwOS when only basic switching functions are needed. Power redundancy through two DC jacks and PoE-IN support ensures the switch stays operational even during single power source failures.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #E65611;\"\u003eBest
