MikroTik CRS354-48G-4S+2Q+RM — enterprise switch for core and aggregation networking

MikroTik CRS354-48G-4S+2Q+RM is an enterprise rackmount switch with 48 Gigabit RJ45 ports, four SFP+ 10G ports, and two QSFP+ 40G ports, designed for office, campus, and distributed infrastructures where copper port density, high-speed optical uplinks, and power redundancy are required at a price-to-performance ratio that stands out against market alternatives. With non-blocking throughput of 168 Gbps and switching capacity of 336 Gbps, it handles the most demanding scenarios without performance compromises.

The 48 Gigabit RJ45 ports connect the full range of wired equipment — workstations, servers, IP cameras, VoIP phones — without additional access switches. Four SFP+ 10G ports provide fast optical uplinks to core infrastructure or NAS, while two QSFP+ 40G ports enable interconnection with high-performance switches or core routers at maximum speed. Dual redundant power supply with two PSU slots eliminates power as a single point of failure. The included cable management bracket keeps rack infrastructure organized.

CRS354-48G-4S+2Q+RM supports dual boot between RouterOS v7 license level 5 and SwOS — complete flexibility between advanced Layer 3 management with routing, VPN, and scripting and a streamlined interface for rapid configuration. The RJ45 serial console provides out-of-band access, and active cooling via three fans maintains stable operating temperature under continuous load.

Recommended for medium and large offices with high wired device density, campuses requiring 10G and 40G uplinks from a single switch, network infrastructures where power redundancy and maximum throughput are simultaneous requirements, and any enterprise scenario where a switch with 48 Gigabit ports, SFP+ 10G, and QSFP+ 40G delivers the best price-to-performance ratio among comparable alternatives. RouterOS v7 level 5 license and free lifetime software updates are included.
