MikroTik Cloud Core Router, CCR2004-1G-2XS-PCIe

CCR2004-1G-2XS-PCIe is a very smart and standalone router with RouterOS installed with L6 license and powered by your server or computer with its own computing CPU 1.5GHz clock and 4 cores for firewall, access control for home multimedia and file servers and even control some traffic in data centers. This router is equipped with 2× SFP28 interface (25 Gbps), Gigabit Ethernet and PCI-e which is used for powering the router and you can see more 4 virtual interfaces . The two interfaces in SFP28 slots and the remaining two virtual Ethernet-PCIe interfaces are bridged with a Gigabit Ethernet port for management access. A new Passthrough mode has been implemented to make this CCR device work as a network card. In essence, this is FastForward FastPath mode which can also transmit hardware line statuses. However, this form-factor has certain limitations that you should keep in mind. Compared to ASIC-based assemblies, the CCR NIC needs some time to start. If the host system is started before the CCR card, it will not appear among the available devices. You should add a PCIe device initialization delay after power up in the BIOS. Otherwise, you will need to reinitialize the PCIe device from the host system.
