NVIDIA ConnectX-5 EN 10/25GbE Dual-Port SFP28 NIC

Exact specifications

Use cases and applications

Use this adapter to connect a capable host to a 10G or 25G Ethernet network. Faster storage access still depends on the storage array, switch, cabling and application. The dual ports do not automatically double the speed of one connection; bonding and failover need operating-system and switch configuration.

Compatibility and important limits

• Provide a compatible PCIe slot with sufficient electrical lanes, full-height bracket clearance and airflow across the adapter.
• Match SFP28 optics or DAC coding, firmware and switch support at both ends; port shape alone is not a compatibility certificate.
• This exact EN model is Ethernet. Do not assume InfiniBand operation from another ConnectX-5 family model.

Packaging and included items

One network adapter in the tall-bracket variant. Optics, DAC cables and an additional low-profile bracket are not promised. Retail-box presentation is not specified.

Image note: The manufacturer reference photo illustrates the ConnectX-5 dual-SFP28 card design. The exact supplied variant is identified by the part number; the image is not proof of an etched ordering code.

Optional accessories and alternatives

Accessories and alternatives are optional, not a required bundle. Check exact connectors, platform fit and supported media before combining products. Browse Components for the wider range.

Packaging measurements

Estimated shipping package for quotation planning: 30 × 22 × 8 cm. Catalogue gross unit weight: 0.7 kg; this is not the bare-product mass. Package dimensions are a planning estimate, not a measured manufacturer specification. Confirm the final packed parcel before dispatch.

Dispatch and warranty

Dispatch within 48 hours. Dispatch and destination delivery are separate; stock is not reserved by viewing this page.

Warranty and service: 12-month return-to-base service. NVIDIA also documents a one-year limited hardware warranty for its networking adapters without an active support contract; this is factory RMA coverage, not an on-site or software-support plan. Entitlement and the applicable start date are checked against the supplied unit and purchase documents.

How to start a claim: Contact Mineshop support with your order number, product serial number where present, a fault description and useful diagnostic photos. Wait for return authorisation and packing instructions before sending the product.

Commercial warranty and service terms do not limit your statutory rights against the seller. Physical damage, installation errors and use outside the manufacturer’s specifications are assessed under the applicable terms; no repair turnaround or advance replacement is promised.

Frequently asked questions

Which ConnectX-5 ordering code is this?

900-9X5AZ-0053-0T3 maps to the legacy MCX512A-ACAT ordering code. It is the dual-SFP28, PCIe 3.0 x8, tall-bracket Ethernet variant; other ConnectX-5 part numbers can have different ports or interfaces.

Is this a 100GbE or InfiniBand adapter?

No. This listing is the 10/25GbE Ethernet SFP28 variant, not a QSFP28 100G card or an InfiniBand model.

Are SFP28 transceivers or DAC cables included?

They are not included in the stated contents. Select approved media separately and check both adapter and switch compatibility.

Will any physical x16 slot work?

Check electrical lane allocation, BIOS support, bracket space and cooling. A long physical slot does not prove the required lanes are available.

Do two ports double every transfer speed?

No. Individual links, software and switch configuration determine performance. Link aggregation is not automatic bandwidth pooling for every connection.

When is dispatch expected?

Dispatch within 48 hours. This is a dispatch estimate, not the arrival time. Delivery transit depends on destination and service.
