MikroTik CCR2004-16G-2S+ Quad-Core 10G RouterOS L6

The CCR2004-16G-2S+ (product code: CCR2004-16G-2S+) is the Gigabit-focused member of MikroTik's CCR2004 router family, distinguished within the series by its emphasis on single-core CPU performance. The Annapurna Labs AL32400 processor operates at 1700 MHz across four ARM 64-bit cores (four threads), paired with 4 GB of RAM and 128 MB of NAND flash storage. This combination delivers strong performance across demanding RouterOS workloads including complex multi-rule firewall policies, BGP/OSPF routing tables, and deep packet inspection.

The 16× 10/100/1000 Mbps Gigabit Ethernet ports — managed by the 88E6191X switch chip — provide high-density LAN or WAN connectivity suited to medium and large enterprise edge or aggregation deployments. The two SFP+ slots accept 1G or 10G SFP modules, serving as uplinks to a distribution switch, core router, or ISP hand-off point. Ethernet test results show routing throughput of up to 35.5 Gbps (fast path, 1518-byte frames) across all ports simultaneously.

IPsec performance is a particular strength of the AL32400 platform. Testing with 256 tunnels using AES-128-CBC + SHA1 at 1400-byte packets yields approximately 2.6 Gbps — making the CCR2004-16G-2S+ a capable VPN concentrator for organisations running large numbers of site-to-site or remote access tunnels. The same throughput holds across AES-256-CBC cipher variants, indicating hardware-assisted crypto acceleration.

Power resilience is provided by two hot-swap PSU slots, accepting a wide AC input range of 100–240 V at 50–60 Hz. Either PSU can be removed and replaced under load without interrupting operation. Maximum power consumption is 48 W under full load (35 W without SFP attachments), with cooling handled by two active fans. A single USB port is available for storage or configuration use, along with an RJ45 serial console port for out-of-band management. CPU temperature, PCB temperature, and voltage monitors are included. IP20 indoor rating applies.

The unit ships with rack ears, two IEC power cords, and a K-57 kit, and is dimensioned at 443 × 210 × 44 mm for standard 1U rack installation. Certifications include CE, EAC, and RoHS, with an MTBF of approximately 200,000 hours at 25 °C.
