The card is colored green and offers reliable performance for data-intensive applications.

## Long description

The NVIDIA Mellanox Technologies MCX631102AS-ADAT ConnectX-6 Lx is an internal fiber network card that delivers up to 25 Gbit/s per port and supports dual SFP28 ports. Designed for server and data center installations, the adapter uses a PCI Express host interface (compatible with PCIe Gen3/Gen4 x8) to provide low-latency, high-throughput connectivity. The card is built for wired fiber networks and comes in a green PCB finish, offering a compact, tall-bracket form factor suitable for a range of chassis and rack-mounted systems.
Advantages
The card provides dual-port 25GbE fiber connectivity with industry-standard SFP28 transceiver support and a PCIe x8 host interface for sustained high bandwidth. It is engineered for efficient data forwarding, low latency, and high packet rate performance, which helps maintain predictable network behavior under load. The adapter supports Secure Boot and a no-crypto configuration, simplifying deployment where cryptographic offload is not required. Its ConnectX-6 Lx architecture enables interoperability with common data center networking stacks and management tools.
Suitable for (tasks / use cases)
High-performance server networking in data center and colocation environments
Virtualization hosts and hyperconverged infrastructure requiring 25GbE links
Storage networks and SAN front-end connectivity over fiber
High-throughput applications such as database replication and backup
Edge and enterprise switches requiring uplink or server connectivity

How to use
Install the MCX631102AS-ADAT into an available PCIe x8 or x16 slot on a powered-off server motherboard, secure the card with the bracket to the chassis, and insert compatible SFP28 fiber transceivers into the SFP28 cages. Connect fiber optic cables to the transceivers and ensure the host system firmware and operating system have the appropriate Mellanox/NVIDIA drivers installed. Configure network settings in the operating system or management software to assign IP addresses, MTU sizes, and link aggregation as required for the deployment.
Usage recommendations
Use certified SFP28 transceivers and single-mode or multimode fiber consistent with the transceiver specifications. Keep firmware and drivers up to date to ensure compatibility with PCIe Gen4 platforms and to benefit from performance and stability fixes. Verify chassis airflow and cooling to maintain recommended operating temperatures for sustained high-speed operation.
