Lenovo ThinkStation Broadcom BCM5719-4P Quad-port Gigabit Ethernet Adapter network card

SKU CH-9JKZ-VQDSH

Quad-port Gigabit Ethernet adapter with PCIe 2.1 x4 interface delivers 10/100/1000 Mbps speeds across four ports

  • Quad-port design connects four networks simultaneously
  • PCIe 2.1 interface delivers 1000 Mbit/s throughput
  • Broadcom BCM5719-4P controller handles offload tasks efficiently
  • Supports 10/100/1000Base-TX speeds on each port
  • Reduces host CPU load through hardware acceleration

Quad-port Gigabit adapter for ThinkStation servers

The Lenovo ThinkStation Broadcom BCM5719-4P installs in a PCI Express 2.1 slot and presents four 10/100/1000Base-TX ports for wired Ethernet connectivity. It targets administrators who need multiple Gigabit links on a single card for server or workstation deployments.

Four ports with offload to reduce host load

Each port negotiates at 10, 100 or 1000 Mbit/s and the controller supports Large Send, TCP segmentation, TCP/UDP/IP checksum offload and Receive Side Scaling. These features lower CPU utilisation during sustained traffic, but the card remains limited to Gigabit speeds on copper media.

Plug-in card with no extra software bundle

The adapter ships as a bare plug-in card; no cables, brackets or management utilities are included in the package. Buyers requiring fibre uplinks or pre-installed driver media will need to source those separately.

Questions about this item

Will the BCM5719-4P quad-port adapter work in my older PCIe 2.0 slot?

Yes, the card complies with the PCI Express 2.1 specification and is backward compatible with PCIe 2.0 and 1.0 slots, though it will operate at the lower slot speed.

How can I verify the Broadcom BCM5719-4P is running at full 1000 Mbit/s after installation?

Check the link speed in your OS network settings or the adapter's driver properties; it should report 1.0 Gbps full duplex on each active port when connected to a Gigabit switch.

Does the Lenovo ThinkStation BCM5719-4P include the SFP transceivers needed for the optical fibre ports?

The adapter provides four SFP cages for optical fibre; SFP transceivers and fibre patch cables are sold separately and must match your link distance and wavelength requirements.
