[ MODEL-SPECIFIC NETWORK HARDWARE ]
Broadcom NetXtreme BCM5719 Ethernet Controller
Four-port 10/100/1000BASE-T PCIe controller used in server NICs and embedded boards. This is a controller/chip record; finished-card details are implementation-specific.
IDENTIFICATION: Match complete component top-mark, stepping and board revision. Nominal signaling rates are not measurements of application throughput.
Exact specifications and compatibility
| Dedicated subcategory | Ethernet controllers and PHYs |
|---|---|
| Exact controller identity | Broadcom NetXtreme BCM5719 Ethernet Controller |
| Component / board identity | Quad-port PCIe Gigabit Ethernet controller; a board adds PHY-side circuitry and four external ports. |
| PCIe bus and host interface | PCI Express Gen2 x4 host interface. |
| Ethernet ports / physical interface | Four 10/100/1000BASE-T Ethernet interfaces in the controller implementation; board routing and connector count vary by product. |
| Nominal rate (not measured) | Up to 1 Gb/s nominal per port (4 Gb/s aggregate line rate); not measured throughput. |
| Drivers and OS compatibility | Linux bnx2 driver supports BCM5719 devices; Broadcom/OEM packages provide support for selected Windows Server versions; the HPE source identifies a BCM5719 four-port BASE-T OCP3 implementation. Server firmware, subsystem IDs and OEM lifecycle determine exact compatibility. |
| Board / system compatibility | Use on an adapter or board designed for BCM5719, with PCIe x4 host link, suitable power and four port-side circuits. Do not assume the IC package directly exposes an RJ-45 interface. |
| Revision and variant warning | BCM5719 is the controller silicon; branded cards have distinct PCI subsystem IDs, firmware, bracket and port wiring. Verify the exact adapter assembly before selecting drivers. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result records the host, link partner, medium, driver/firmware, traffic pattern, test tool and duration. |
Identification and revision notes
BCM5719 is the controller silicon; branded cards have distinct PCI subsystem IDs, firmware, bracket and port wiring. Verify the exact adapter assembly before selecting drivers.

Archival and preservation notes
Record package top-mark, adapter board number, subsystem IDs, firmware and any OEM heatsink. Maintain server airflow and note whether ports are copper or board-specific variants.
For an installed specimen, preserve source URL, access date, source revision and label/condition notes. Do not infer connector count or board-level compatibility from controller family name alone.
