The MikroTik CRS520-4XS-16XQ-RM is a high-end switch designed for future-proof enterprise networks and data centers, combining ultra-fast connectivity and extra processing power in a single rack unit. With 16 100 Gbps QSFP28 ports, 4 25 Gbps SFP28 ports, and 2 10 Gbps Ethernet ports, it enables centralization and management of highly complex network infrastructures. This port diversity allows it to handle the tasks of multiple devices in scenarios such as server farms requiring high bandwidth, multimedia processing studios, or backbone connections. The technical strength of this product comes not only from the high-speed ports but also from the powerful hardware familiar from the CCR series routers. A quad-core ARM processor clocked at 2 GHz and 4 GB of DDR4 RAM elevate the device beyond a typical switch. It can run advanced routing protocols like OSPF/BGP, management VPNs, Access Control Lists (ACL), Jumbo frames, and even hardware-accelerated L3 routing without issues. The capabilities of the Marvell 98CX8410 switch chip are further expanded with regular MikroTik RouterOS v7 software updates, keeping the device future-proof for years. The CRS520-4XS-16XQ-RM can be reliably deployed in critical environments requiring high availability. It features two hot-swappable power supplies and four hot-swappable fans, operating stably across a wide temperature range from -20°C to +50°C. The extra processing power, combined with its license level, makes this device not just a traffic forwarder but a central brain that actively manages and optimizes the network. All these features come with one of the best price-per-100-Gigabit-port ratios on the market.
