Network Module with 4x 2.5GbE Copper Ports & Bypass Function


  • Intel® I225-LM LAN controller
  • 4x 2.5GbE RJ45 ports
  • 2 pairs bypass segments
  • Based on OCP NIC 3.0 spec with extended depth of OCP NIC 3.0 SFF physical form factor

The Portwell PNC series offers OCP (Open Compute Project) NIC 3.0 cards with network bypass function, an industry-leading design concept. Featuring a convenient thumbscrew pull-tab design to simplify maintenance and upgrades, the PNC series NICs are also designed on a compact form factor, and yet are configured with high port density to optimize connectivity options. Furthermore, the PNC series of network adapters helps ensure network connection and business continuity with its built-in network bypass function to optimize uptime, fail-safe network connectivity, as well as network security, resilience and threat prevention.

The PNC-EB4R-G2 network adapter features Portwell’s innovative proprietary design based on OCP NIC 3.0 specification with extended depth of the OCP NIC 3.0 SFF physical form factor, to provide even higher port density as well as more application design flexibility. It is built with 4x 2.5GbE copper ports and network bypass function, and is designed with Intel Ethernet controller, delivering energy efficiency, seamless interoperability, optimized load balancing, and enhanced agility through Data Plane Development Kit (DPDK) drivers.

Offering a comprehensive feature set to ensure superior performance and reliability, the PNC-EB4R-G2 bypass network adapter is an ideal critical component for modern network infrastructure in diverse applications for next-generation firewalls, unified threat management (UTM) solutions, network routers, gateways, and software-defined wide-area networks (SD-WAN).
