MikroTik CRS354-48G-4S+2Q+RM 48-Port 40G Switch

The MikroTik CRS354-48G-4S+2Q+RM is a high-density 1U rackmount dual-boot switch — 48× GbE RJ45, 4× SFP+ 10G, and 2× QSFP+ 40G, with 168 Gbps non-blocking throughput and dual redundant AC power, running RouterOS v7 License 5 or SwitchOS.

**48× GbE + 4× SFP+ 10G + 2× QSFP+ 40G — three port speeds in one 1U chassis**

48 GbE RJ45 ports handle all standard copper endpoint connections — servers, workstations, APs, and IP phones. 4× SFP+ 10G ports provide inter-switch or uplink connectivity. 2× QSFP+ 40G ports enable direct high-speed spine connections — eliminating the 10G uplink bottleneck for high-throughput core deployments. No PoE on this model — the non-PoE variant to the CRS354-48P-4S+2Q+RM.

**168 Gbps non-blocking throughput — 336 Gbps switching capacity**

98DX3257 switch chip — 168 Gbps non-blocking throughput, 336 Gbps switching capacity, 235 Mpps forwarding rate. No oversubscription at full 48-port GbE line rate with simultaneous 10G and 40G uplink traffic.

**Dual redundant AC power — 2 PSU slots, 2× IEC cords included**

Two independent 100–240V AC inputs with two PSU slots — if one PSU fails the switch remains online. Universal input voltage — compatible with North American 120V and international 230V mains without modification. 2× IEC cords included.

**Dual boot — RouterOS L5 or SwitchOS**

Boot into SwitchOS for lightweight web-managed Layer 2 — VLAN, port isolation, STP/RSTP, mirroring, bandwidth limiting. Boot into RouterOS v7 License 5 for full Layer 3 routing, firewall, NAT, and scripting. Both OSes preinstalled and licensed. Free software updates for the life of the product or minimum 5 years from purchase.

**Canadian market note:** CE, EAC, RoHS only — no FCC, no IC. Wired switch, no wireless transmitter — no ISED wireless type approval required.
