The MikroTik CRS354-48G-4S+2Q+RM is a versatile and powerful 1U rackmount switch solution engineered to deliver high port density and extreme throughput for large-scale corporate networks, service provider hubs, and data center deployments. Driven by a Qualcomm QCA9531 CPU operating at 650 MHz alongside a Marvell switch chip, 64 MB RAM, and 16 MB flash storage, it provides uncompromised wire-speed connectivity across all ports simultaneously.
Featuring a comprehensive interface layout, the switch integrates 48x 10/100/1000 Mbps Gigabit Ethernet ports for copper end-point connections, 4x 10G SFP+ cages for rapid 10 Gbps uplinks, and 2x 40G QSFP+ slots for high-capacity 40 Gbps backbone trunking (QSFP+ slots support breakout cables to split into 4x 10G links each). To ensure uninterrupted enterprise operations, the CRS354-48G-4S+2Q+RM comes fitted with dual redundant internal AC power supplies inside a durable 1U steel enclosure. It supports Dual Boot functionality, allowing users to run lightweight SwOS for pure Layer 2 switching or RouterOS Level 5 for full Layer 3 routing and firewall capabilities.
