Kablet router Mikrotik CCR2004-16G-2S+PC Fast Ethernet

The Mikrotik CCR2004-16G-2S+PC is a compact, silent wired router powered by an Amazon Annapurna Labs Alpine v2 CPU with four 64-bit ARMv8-A Cortex-A57 cores running at 1.2 GHz. It provides 16 Gigabit Ethernet ports, two 10G SFP+ cages and an RJ-45 console port on the front panel. The board includes 4 GB DDR4 RAM and 128 MB NAND storage. Each group of eight Gigabit ports is handled by a separate Marvell Amethyst switch chip with a dedicated 10 Gbps full‑duplex link to the CPU; each SFP+ cage also has its own 10 Gbps full‑duplex connection, enabling full wire-speed on all ports when the CPU resources allow.

Advantages

The router delivers significantly higher processing capability compared with previous CCR generations while operating quietly, making it suitable for noise-sensitive environments such as offices, studios, server rooms or homelabs. Its architecture avoids per-port bottlenecks by assigning separate switch chips and dedicated 10 Gbps links to the CPU, and the inclusion of two SFP+ cages provides flexible uplink/downlink options. The device is space‑efficient, energy conscious with typical power consumption around 36 W, and positioned as a cost‑effective option within its product class.

Suitable for

• Small and medium-sized business routing and gateway tasks
• Internal Gigabit network distribution with 10G uplink/downlink via SFP+
• Quiet environments requiring low-noise networking equipment (offices, studios)
• Homelab or server room deployments needing compact, high-throughput routing

How to use

Install the router in a well-ventilated location and connect the power supply. Use the 16 Gigabit Ethernet ports for local network devices and reserve the two 10G SFP+ cages for uplink or high-speed downlink connections to switches or servers. Access the device via the console port or through the network management interface to configure routing, firewall, and other services. Monitor CPU and interface load to ensure the CPU capacity aligns with traffic requirements for sustained wire‑speed performance.

Recommendations

For best results, assign internal traffic to the Gigabit ports and use the SFP+ ports for uplink to core switches or data center connections. Keep firmware updated and place the router where cooling is adequate to maintain stable performance under sustained load.
