Quad-Port Gigabit Ethernet Adapter

The C&N BCM5719-4P is a quad-port Gigabit Ethernet server adapter built on the Broadcom NetXtreme BCM5719 chipset. It connects through a PCI Express x4 interface compatible with v2.1 and v2.0 slots and fits both standard and low-profile chassis with the included bracket. The card targets servers and workstations needing four 10/100/1000 Mbps copper links in a single slot.

Suited For Multi-OS Server Deployments

This adapter suits administrators running Windows Server, Linux distributions such as Ubuntu, Debian, CentOS, Red Hat, Oracle or SUSE, and hypervisors including VMware ESXi 5 through 8, vSphere and Hyper-V. It supports IEEE 802.1Q VLAN tagging, 802.1p priority and 802.3az Energy Efficient Ethernet. Builders who need fiber connectivity, 2.5G or 10G speeds, or a single- or dual-port card should look elsewhere.

Sustained Load Offload Behaviour

Under continuous traffic the BCM5719 hardware handles TCP segmentation, Large Send and TCP/UDP/IP checksum offload across all four ports, reducing host CPU cycles. Receive Side Scaling distributes incoming packets over multiple processor queues to maintain throughput. The PCIe x4 5 GT/s or 2.5 GT/s link provides headroom for simultaneous full-duplex Gigabit streams without saturating the bus.

Questions about this item

Does this quad-port adapter require a PCIe x4 or larger slot to operate?

The card uses a PCIe x4 interface and is compatible with x8 and x16 slots, so any slot of x4 width or wider will work.

Can the BCM5719-4P run in a server that only has PCIe 1.x slots?

Yes, the manufacturer highlights confirm compatibility with both PCIe v1.x and v2.x interfaces, so it will function in a 1.x slot at the lower speed.

How can I verify all four ports are active after installing the driver?

Each port has its own link LED; solid or blinking green indicates a live 10/100/1000 Mbps connection, and the OS network panel will list four separate Ethernet adapters.
