This is a Silicom PE2G4BPI35LA-SD Quad-Port Gigabit Ethernet PCIe Bypass Network Adapter designed for mission-critical networking environments. Based on the Intel i350-AM4 controller, this enterprise-grade NIC provides four RJ45 Gigabit Ethernet ports with hardware bypass capability, making it ideal for inline security appliances such as firewalls, IDS/IPS systems, load balancers, and high-availability network deployments.

The built-in bypass functionality ensures continuous network traffic flow by automatically switching ports into bypass mode in the event of system failure, power loss, or software crash—helping prevent network downtime in production environments.
