Lenovo 4XC7A08236 network card Internal Ethernet 10000 Mbit/s

The Lenovo 4XC7A08236 is an internal dual‑port 10Gb BASE‑T network card based on the Broadcom 57416 solution. It is fully compliant with IEEE 802.3an and provides high‑speed wired Ethernet over copper cabling with a maximum data transfer rate of 10000 Mbit/s. The card uses a PCI Express host interface and is designed for integration into servers and workstations that require reliable 10 Gb connectivity.

Advantages

The adapter delivers dual 10GBASE‑T ports on copper cabling, enabling high throughput without needing fiber optics. Compliance with IEEE 802.3an and IEEE 802.3ab standards ensures interoperability with existing network equipment. Using PCI Express as the host interface provides low latency and adequate bus bandwidth for demanding applications. The internal form factor suits rack servers and tower workstations where an onboard high‑speed network interface is required.

Suitable for

• Server and data center network uplinks
• High‑performance storage and backup systems
• Virtualization hosts and hyperconverged infrastructure
• Workstations requiring 10 Gb Ethernet

How to use

Install the card into an available PCI Express slot on a compatible server or workstation following the system vendor's service manual. Connect the Ethernet copper cables to the RJ‑45 ports and verify link lights to confirm physical connectivity. Install vendor or Broadcom drivers appropriate for the operating system to enable full functionality and features. Configure network settings (IP addressing, MTU, link aggregation, VLANs) through the operating system or network management tools according to your infrastructure requirements.

Recommendations

Use certified Cat6a or better cabling for reliable 10 Gb BASE‑T operation at full speed and keep cable runs within specified length limits. Ensure the host system has available PCIe lanes and sufficient cooling. Verify driver and firmware versions for compatibility with the OS and network management features before deployment.
