The MikroTik CRS354-48G-4S+2Q+RM is a managed access switch with 48 Gigabit RJ45 ports, four SFP+ slots (10 Gbps) and two QSFP+ slots (40 Gbps) in a 1U rack-mount chassis. The model covers an entire floor of an office building or a large department: workstations, IP phones, printers and Wi-Fi access points all connect to a single device. Management runs on RouterOS — MikroTik's own operating system with VLAN, routing, firewall and monitoring support. The RM in the name stands for rack-mount hardware — the switch goes into a 19-inch server cabinet without extra accessories.
The main argument for the CRS354 is its uplink headroom. Four SFP+ ports provide 10 Gbps to the network core, while two 40 Gbps QSFP+ ports allow a backbone that holds up even with all 48 copper ports fully loaded. Switching is done in hardware by the switching fabric regardless of CPU load, so workstation traffic never degrades. For a network designed with growth in mind, this means the uplink will not need upgrading a year after launch.
Advantages
- 48 Gigabit RJ45 ports — a floor or department on a single device
- Four SFP+ 10 Gbps and two QSFP+ 40 Gbps for bottleneck-free uplinks
- Hardware switching — throughput independent of CPU load
- RouterOS: VLAN, routing, firewall and monitoring included
- 1U rack chassis with 19" cabinet mounting hardware
- One CRS354 replaces a pair of 24-port switches, saving rack units and power
Applications
- Floor distribution nodes in office buildings
- Corporate networks of mid-sized businesses
- Server rooms and mini data centers
- Video surveillance networks with many cameras
- Educational and administrative institutions
Installation and setup
The switch is designed for a 19-inch rack or wall cabinet; active cooling makes the server room, not an office, its proper location. At the design stage it pays to split the ports into VLANs in advance: workstations, telephony, cameras and Wi-Fi are isolated from each other using RouterOS tools. Uplinks are built with SFP+/QSFP+ modules or DAC cables, selected by fiber type and distance to the network core. The two QSFP+ ports are convenient for aggregation with a second identical switch or a 40 Gbps link to the core. satsolutions.uz supplies the CRS354 from stock in Tashkent together with modules and patch cords and takes on turnkey network design and configuration.
