CWWK 1U C236 19" Rackmount Firewall i3-8100/i5-9400/i7-8700 Router PC 8 I226V LAN SFP+ 10Gbe DDR4 OPNsense Network Appliance,Upgradable 2U

Flexible LGA1151 CPU Platform

Supports Multiple Intel Processor Options

The C236 platform uses an LGA1151 CPU socket and supports multiple Intel processor configurations. Users can choose a pre-configured CPU version or select a suitable processor based on firewall performance, VPN throughput, routing load, and multi-service requirements.

For basic firewall and routing use, an Intel Core i3 configuration is a practical choice. For heavier VPN, multi-WAN, VLAN, and network service workloads, Intel Core i5 or Core i7 configurations provide stronger performance headroom.

1U Rackmount Firewall PC Specifications

Internal Layout and Expansion Design

Rich Interfaces for Storage, Network and System Expansion

The C236 platform provides multiple internal interfaces, including DDR4 SO-DIMM memory slots, LGA1151 CPU socket, mSATA slot, SATA ports, Mini PCIe, SIM card slot, GPIO pin header, USB headers, and PCIe x8 expansion. This gives the system more flexibility than a fixed mini PC and makes it suitable for users who need a rack-mounted firewall appliance with better expansion potential.

Standard 8 × Intel i226-V 2.5GbE LAN Version

For Multi-WAN, VLAN and Firewall Deployment

The standard version provides 8 × Intel i226-V 2.5GbE RJ45 LAN ports. It is suitable for pfSense, OPNsense, OpenWrt, Linux routing, ESXi network labs, multi-WAN routing, VLAN segmentation, and small office firewall deployment.

With 8 × 2.5GbE LAN ports, users can separate WAN, LAN, guest network, IoT devices, storage network, and management network more clearly.

Optional 2 × 10GbE SFP+ Expansion

For Higher-Speed Uplink and Fiber Network Use

For users who need faster uplink or fiber network connectivity, the C236 platform can be configured with 2 × Intel 82599ES 10GbE SFP+ ports. This version is suitable for NAS uplink, switch uplink, virtualization network, high-speed LAN, and advanced firewall deployment.

The 8 × 2.5GbE + 2 × 10GbE SFP+ version is a practical choice for users who need both multiple RJ45 LAN ports and high-speed SFP+ connectivity.

Optional 4 × 10GbE SFP+ Expansion

For Advanced Network Segmentation and High-Speed Lab Use

For more advanced network environments, the C236 platform can also support a 4 × Intel X710 10GbE SFP+ expansion version. This configuration is suitable for users who need more high-speed fiber ports for network segmentation, virtualization, NAS traffic, switch uplink, firewall testing, or home lab network design.

The 8 × 2.5GbE + 4 × 10GbE SFP+ version is better suited for users who need stronger network expansion and higher-speed connectivity than the standard 8-LAN version.

19-Inch 1U Rackmount Chassis with Active Cooling

Designed for Long-Term Rack Deployment

The C236 firewall PC uses a 19-inch 1U rackmount chassis with cooling fans and a dust filter. Compared with desktop firewall appliances, the rackmount design is easier to install in a standard server rack or network cabinet. The active cooling structure helps improve airflow and supports stable long-term operation in rack-based environments.

This design is suitable for home lab racks, small office server rooms, network cabinets, firewall deployment, and always-on gateway applications.

Optional 2U Rackmount Chassis Version

More Internal Space for Flexible Rack Deployment

In addition to the standard 1U rackmount chassis, the CWWK C236 platform can also support a 2U rackmount chassis version for users who need more internal space, easier maintenance, and a larger chassis structure for specific deployment requirements.

The 2U chassis measures approximately 435 × 440 × 90mm, making it suitable for standard rack cabinet installation. Compared with the 1U version, the 2U chassis provides a larger physical structure, which can be useful for customers who prefer more internal room for airflow, cable management, storage layout, or project-based hardware customization.

2U Front and Rear Interface Layout

Clear I/O Access for Rack Cabinet Installation

The 2U chassis version provides a practical front and rear I/O layout for rack-mounted network deployment. The front panel includes console, USB 3.0, RJ45 LAN ports, GPIO button, hard disk status light, and power status light. The rear panel includes VGA, chassis cooling fan, power switch, and AC socket.

This layout is suitable for users who need easier rack access, clear front-side network cabling, and stable long-term deployment in a server rack, office network cabinet, or small business equipment room.
