MikroTik CRS354-48P-4S+2Q+RM — enterprise PoE switch for SMB and corporate infrastructures
MikroTik CRS354-48P-4S+2Q+RM is an enterprise rackmount switch with 48 Gigabit PoE ports, four 10G SFP+ ports, and two 40G QSFP+ ports, designed for demanding network infrastructures where powering large numbers of PoE devices and high-speed connectivity are simultaneous requirements. With 700W of available PoE power and full 802.3af/at auto-sensing support across all 48 ports, it eliminates the need for external PoE injectors or additional switches in a single 1U unit.
All 48 Ethernet ports support passive PoE, low voltage PoE, and 802.3af/at (PoE/PoE+) with auto-sensing — the switch automatically detects each connected device's requirements and delivers the appropriate power. The 750W internal power supply covers maximum-density PoE device scenarios. Non-blocking throughput of 168 Gbps and switching capacity of 336 Gbps eliminate any internal bottlenecks. The 40G QSFP+ ports handle core switch interconnects or high-speed uplinks, while the 10G SFP+ ports cover standard fiber connections. The included cable management bracket keeps rack infrastructure organized.
CRS354-48P-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 firewall capabilities and a streamlined switching-focused interface. The front-panel RJ45 serial console port provides out-of-band access. Active cooling via four fans maintains stable operating temperature at maximum load in permanent datacenter or server room deployments.
Recommended for campuses and offices with high PoE device density — WiFi access points, IP cameras, VoIP phones — small and medium datacenter infrastructures requiring 40G uplinks, distributed networks where a single switch must simultaneously cover PoE power delivery and high-speed connectivity, and any enterprise scenario where price-to-performance ratio versus market alternatives is a decision criterion. RouterOS v7 level 5 license and free lifetime software updates are included.
