XMC403 – Dual 10GbE Switched Mezzanine Card by Kontron

The Kontron XMC403 is a dual 10 Gigabit Ethernet switched mezzanine card engineered for embedded computing platforms that demand high-throughput network connectivity with minimal CPU overhead. At its core is the Intel X710-BM2 Ethernet controller, delivering two independent 10GbE SFP+ interfaces connected to the host via a PCI Express Gen 3.0 x8 interface, enabling full line-rate bidirectional throughput without burdening the host processor. The hardware offload capabilities built into the Intel X710-BM2 free the host CPU from network I/O processing, a critical advantage in latency-sensitive or compute-intensive applications such as signal processing, data acquisition, communications infrastructure, and storage over Ethernet. The XMC403 supports both optical fibre transceivers and direct-attach copper cables through its dual SFP+ cages, offering the flexibility to match the physical layer to the specific deployment environment. Intelligent auto-detection of copper network configurations further simplifies commissioning. Compliant with VITA 42.0, VITA 42.3, VITA 42.6, and IEEE 1386.1, the XMC403 integrates cleanly into standard single-board computer and carrier card ecosystems. The card measures 74 x 149mm as a single XMC module and weighs just 100g, with an exceptional MTBF of 929,999 hours calculated to MIL-HDBK-217 FN2 Ground Benign at 30°C. It operates between 0 and +50°C, stores from -55 to +85°C, and is rated for operation up to 4,000 metres altitude. A coated variant, the XMC403-C, is available for enhanced environmental protection. Software support covers Linux Debian, Windows 10/11 IoT Enterprise LTSC, and Windows Server 2022. Available from Recab, your Nordic partner for Kontron embedded computing solutions.
