Lenovo 4C57A14366 interface cards/adapter Internal SFP+

The Lenovo 4C57A14366 is an internal SFP+ interface card designed for servers that require enhanced fibre-channel connectivity. Built for compatibility with ThinkSystem DE4000H, this card supports high-throughput links with a maximum data transfer rate of 16 Gbit/s. Its passive cooling design reduces noise and power draw, while a multicolour finish identifies port or module status during installation and maintenance.

Advantages

This internal interface card provides a compact SFP+ solution that delivers low-latency, high-bandwidth connectivity for storage and server environments. Passive cooling eliminates the need for dedicated fans on the module itself, simplifying integration into existing server airflow. The 16 Gbit/s transfer capability supports modern SAN workloads and reduces bottlenecks when connecting to compatible arrays.

Suitable for

• Expanding storage or SAN connectivity in rack and blade servers
• High-throughput data transfer between servers and storage arrays
• Deployments using ThinkSystem DE4000H storage systems
• Environments where passive cooling and minimal noise are required

Key specifications

• Interface type: internal SFP+ card
• Maximum data transfer rate: 16 Gbit/s
• Cooling: passive
• Design: multicolour module housing for visual identification
• Form factor: low-profile server card for internal installation

How to use

Install the card into an appropriate internal expansion slot on a supported server following the server manufacturer’s service manual. Secure the module and connect SFP+ transceivers and fibre or direct-attach cables as required by your network topology. After physical installation, verify that firmware and drivers on the host server are up to date, then configure the SAN or network settings through the operating system or storage management software.

Recommendations

Confirm compatibility with your server model and storage array before purchase. Use manufacturer-recommended SFP+ transceivers and quality fibre or DAC cables to ensure optimal signal integrity. Monitor link status after installation and keep firmware and host drivers current to maintain performance and stability.
