Lenovo Broadcom 5719 Interný Ethernet 1000 Mbit/s

The Lenovo Broadcom 5719 Internal Ethernet adapter is a wired Gigabit network card designed for installation in servers or workstations via a PCI Express slot. Delivering up to 1000 Mbit/s, it supports common Ethernet standards including IEEE 1588, 802.1Q, 802.1as, 802.3ad, 802.3az, 802.3x and 802.3z. The adapter is available in multiport variants within the Broadcom NetXtreme family and is compatible with ThinkSystem and System x servers, providing a durable stainless steel and green finish suited for rack-mounted environments.

Advantages

The adapter offers reliable wired connectivity at Gigabit speeds with broad standards support for network timing, VLAN tagging, link aggregation and energy-efficient Ethernet. Its PCI Express host interface ensures a direct connection to the system bus for low-latency data transfer. Compatibility with Lenovo server platforms and the NetXtreme family simplifies deployment and driver support in data centre and enterprise environments.

How to use

Install the adapter into an available PCI Express slot on a powered-down server or workstation according to the chassis and motherboard instructions. Secure the card and connect the Ethernet cables to the appropriate ports. Power on the system and install the vendor-provided or platform-supported drivers. Configure network settings, VLANs, link aggregation and time synchronization within the operating system or network management tools as required.

Recommendations

For optimal performance in enterprise deployments, use certified drivers from Lenovo or Broadcom, apply firmware updates when available, and configure link aggregation and quality-of-service settings on both adapter and switch sides. Ensure cable quality and switch compatibility for Gigabit operation and enable IEEE 1588 only where precise time synchronization is required to avoid unnecessary configuration overhead.
