What is the CCR2004-16G-2S+?

The CCR2004-16G-2S+ is a routing and switching device that belongs to the CCR2004 series, characterized by the use of the Amazon Annapurna Labs Alpine v2 CPU. Unlike previous models in the CCR family, this device specifically aims to maximize single-core performance, a critical aspect for network operations that require intensive processing per connection, such as queuing. The design is intended to be an “all-in-one” solution for small and medium-sized enterprise networks, eliminating bottlenecks between the ports and the CPU.

What are the main technical features?

The key specifications of the CCR2004-16G-2S+ include:

  • CPU: AL32400 (Amazon Annapurna Labs Alpine v2) with 4 ARMv8-A Cortex-A57 cores at 1.7 GHz.
  • Memory and Storage: 4 GB of DDR4 RAM and 128 MB of NAND storage.
  • Network ports: 16 Gigabit Ethernet ports (connected to two Marvell Amethyst 88E6191X switch chips) and 2 10G SFP+ slots.
  • Additional interfaces: 1 USB 3.0 Type A port and 1 RJ-45 console port.
  • Power supply: Integrated dual redundant power supplies, AC input 100-240 V.
  • Power consumption: Maximum 35 W without accessories, 48 W with accessories.
  • Operating system: RouterOS v7 (exclusive).
  • Dimensions and cooling: 1U rackmount form factor (443 x 210 x 44 mm) with active cooling.

Who is it for and in which scenarios does it make sense?

This router is suitable for network administrators managing offices or small WISP infrastructures where the internal bandwidth is Gigabit Ethernet and the uplink/downlink connections are 10G fiber optic. The typical scenario involves using the 16 Ethernet ports for the internal network and the two SFP+ slots for the connection to the operator or for traffic aggregation. The integrated power supply redundancy makes it suitable for environments where reliability is a priority, without the need to purchase separate external power supply units.

What to know before choosing it?

It is fundamental to note that the CCR2004-16G-2S+ exclusively supports RouterOS v7; it is not compatible with previous versions of the operating system. Each group of 8 Ethernet ports is connected to a separate switch chip, and each SFP+ slot has a dedicated 10 Gbps full-duplex line to the CPU, ensuring that all ports can reach line speed as long as the CPU is not saturated. The device operates in a temperature range from -20°C to +60°C and includes in the package two power cables, rack brackets, and a mounting kit.

Frequently asked questions

Does the CCR2004-16G-2S+ support RouterOS v6?

No, the CCR2004-16G-2S+ is designed to work exclusively with RouterOS v7. It is not possible to install or run previous versions of the operating system on this hardware.

How many power supplies does the CCR2004-16G-2S+ have?

The device includes two redundant power supplies integrated into the case. This means that you do not need to purchase external power supply units to ensure redundancy, simplifying rack installation.

What is the maximum power consumption of the CCR2004-16G-2S+?

The maximum power consumption specified by MikroTik is 35 W without accessories connected and 48 W with accessories. This positions it as one of the most efficient CCR models in terms of performance per watt.

Are the Ethernet ports of the CCR2004-16G-2S+ connected directly to the CPU?

The ports are connected to two Marvell Amethyst (88E6191X) switch chips, which in turn communicate with the CPU via 10 Gbps full-duplex lines. This architecture allows reaching line rate on all ports, limiting the bottleneck to the processing capacity of the CPU itself.
