MREŽNA KARTA/ROUTER MIKROTIK CCR2004-1G-2XS-PCIe 2x 25 Gbps, 1x 1 Gbps

Turn your server into a powerful router with the CCR2004 NIC!
This unique card combines a 2x 25G PCIe Ethernet adapter with the full functionality of a RouterOS-powered CCR.

By default, it appears as four virtual Ethernet interfaces: two for 25G SFP28 passthrough and two bridged with the Gigabit port for management. All settings are fully configurable.

A new Passthrough mode enables wire-speed (100 Gbps with Jumbo frames) while preserving hardware link status—perfect for high-performance server setups.

With a quad-core ARMv8 CPU, 4 GB RAM, and 128 MB storage, it handles firewalls, access control, and traffic shaping without a separate router.

Note: The card takes time to boot. Ensure BIOS has a PCIe initialization delay, or re-init from the host.

We can’t wait to see how you’ll use this compact, high-speed CCR!
Unleash RouterOS in your server!

By default, the PCIe interface will show up as four virtual Ethernet interfaces. Two interfaces in passthrough mode to the 25G SFP28 cages. Remaining two virtual Ethernet-PCIe interfaces are bridged with the Gigabit Ethernet port for management access. The user can configure all interfaces and settings freely since we are running fully functional RouterOS here.

With 4 GB of RAM, 128 MB of NAND storage, and a powerful quad-core ARMv8 64-bit CPU, this device can handle a lot: firewalls, user management and access control for home media and file servers, and even some traffic control in data centers – without the need for a stand-alone router.
