Product Features
Technical Overview
This Gigabit Ethernet card implements PCI Express 2.0 host interface technology, delivering 500 MB/s bandwidth per direction to support simultaneous data transfers across all four ports. The adapter maintains full 1Gb/s throughput on each RJ-45 port when connected via Category 5e or better twisted-pair cabling.
The BCM5719 controller architecture provides hardware-accelerated TCP/IP processing, reducing CPU overhead during network-intensive operations. This efficiency makes the card particularly suitable for virtualization hosts, storage servers, and application servers where network performance directly impacts overall system responsiveness.
Relevant factors for this section include Host Interface, Total Number of Ports, Number of Network (RJ-45) Ports, Media Type Supported. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

User Manual
FAQ
What type of server environments is this Ethernet card designed for?
This HPE BCM5719 Gigabit Ethernet Card is specifically engineered for server deployment in enterprise environments. It's optimized for rack-mounted servers, tower servers, and workstation-class systems that require reliable, high-density network connectivity. The card includes server-specific driver optimizations and thermal design considerations for 24/7 operation in data center and server room conditions.
How many network ports does this adapter provide and what type are they?
This adapter provides four independent network ports, all configured as RJ-45 connectors. These are standard Ethernet ports that support twisted-pair cabling. Having four ports on a single card allows you to connect multiple network segments or implement port aggregation without consuming multiple expansion slots in your server.
What is the maximum data transfer rate supported by this Ethernet card?
Each port on this HPE BCM5719 adapter supports a maximum data transfer rate of 1 Gbit/s (1000 Mbps). This is achieved through 1000Base-T network technology, which operates over standard twisted-pair cabling. The PCI Express 2.0 interface provides sufficient bandwidth to maintain this speed simultaneously across all four ports without performance degradation.
What type of host interface does this network card use?
This Gigabit Ethernet card utilizes a PCI Express 2.0 host interface. This interface provides 500 MB/s of bandwidth per direction, ensuring adequate throughput for all four ports operating at full 1Gb/s speed simultaneously. The PCIe 2.0 standard offers backward compatibility with PCIe 1.x slots while delivering improved performance over earlier interface technologies.
What cabling requirements does this adapter have for network connections?
This adapter supports standard twisted-pair Ethernet cabling, specifically Category 5e, Category 6, or Category 6a cables. It uses 1000Base-T technology, which operates over four pairs of copper wires. The maximum supported cable distance is 100 meters (approximately 328 feet) when using appropriate cabling, making it compatible with most existing network infrastructure without requiring specialized cabling.
What environmental standards does this product meet?
This HPE network adapter is manufactured to comply with the Restriction of Hazardous Substances (RoHS) directive. This means it's constructed without using certain hazardous materials like lead, mercury, cadmium, and specific flame retardants. The RoHS compliance ensures the product meets environmental standards for electronics deployed in enterprise and data center environments.
