1U rack firewall with Intel Atom C3958, 16 GB DDR4, 512 GB NVME, 10 RJ-45 ports and 4 SFP+ uplinks
This 1U rack-mount firewall appliance runs an Intel Atom C3958 processor with 16 GB of DDR4 memory and a 512 GB NVME SSD. It is built for network administrators who need a dedicated hardware platform for open-source routing and security distributions such as OPNsense or pfSense. The unit includes mounting ears for 19-inch racks and supports wall or desktop placement.
The appliance provides ten RJ-45 ports: two Intel I211 and four I350 controllers operating at 1 Gbps, plus four I225-V controllers at 2.5 Gbps. Four SFP+ cages use the X553 interface for fibre uplinks. Aggregate throughput cannot exceed the combined line-rate of these controllers, so total bidirectional traffic is bounded by the 1 Gbps and 2.5 Gbps physical layers fitted.
Verify that your rack depth can accommodate a 484 mm long chassis and that the 100-240 V AC supply matches your facility power. Confirm the SFP+ modules you intend to use are compatible with the X553 interface. Ensure the single PCIe x8 slot and the Mini PCIE or M.2 3052 expansion slots meet any additional card or wireless module requirements you have planned.

The 512 GB capacity ships on the M.2 2280 NVMe PCIe 3.0 x2 slot; the 2.5-inch bay is an additional SATA slot you can populate later for extra storage.
Each SFP+ port is wired to the Intel X553 controller and runs at up to 10 Gbps line rate, so aggregate throughput depends on your switch and cable but the hardware caps at 10 Gbps per port.
The six 1 GbE ports use two I211 and four I350 controllers, while the four 2.5 GbE ports use four I225-V controllers; each controller connects via PCIe so full line-rate on all ten RJ-45 ports is supported simultaneously.
