The MikroTik CSS326-24G-2S+RM is a cost-effective, high-capacity 1U rackmount Layer 2 switch designed for enterprise branch offices, server closets, and ISP access networks. Built to handle non-blocking Layer 2 forwarding at line rates, it provides an ideal combination of high-density copper ports and ultra-fast 10G fiber uplinks.
At its core, the CSS326-24G-2S+RM is driven by a specialized Marvell 88E6393X switch chip operating alongside 2 MB of embedded flash memory. The interface layout includes 24x 10/100/1000 Mbps Gigabit Ethernet ports for client equipment, paired with 2x 10G SFP+ cages that support both 1.25G SFP and 10G SFP+ optical transceiver modules for high-speed trunking over long distances.
Powered exclusively by MikroTik SwitchOS (SwOS), the device is managed via an intuitive web browser interface that gives network administrators granular control over network operations. Features include port-to-port forwarding, MAC filtering, VLAN configurations, traffic mirroring, bandwidth limitation, and packet header field adjustments. Housed in a durable 1U metal rackmount casing with passive fanless cooling, it ensures 100% silent and energy-efficient performance.
