Mellanox MCP7H50-H003R26 Compatible TAA Compliant 200GBase-CU QSFP56 to 2xQSFP56 Infiniband HDR Direct Attach Cable (Passive Twinax, 3m, LSZH)

The Mellanox MCP7H50-H003R26 Compatible TAA Compliant 200GBase-CU QSFP56 to 2xQSFP56 Infiniband HDR Direct Attach Cable (Passive Twinax, 3m, LSZH) is engineered to unlock extreme performance in modern data centers. Designed for demanding workloads and dense rack environments, this high-speed DAC delivers deterministic, low-latency connectivity that is essential for HPC clusters, AI/ML accelerators, and high-throughput storage networks. With a focus on reliability, safety, and compliance, this cable provides a ready-to-deploy solution that helps you scale bandwidth without adding complex switching equipment.

• Extreme bandwidth and HDR readiness: Delivers up to 200 Gbps per link with InfiniBand HDR compatibility, enabling rapid data transfers across multi-node compute fabrics and storage backbones for latency-sensitive applications.
• Direct attach, passive twinax design: A robust copper DAC with no active electronics, offering ultra-low latency, high signal integrity, and reduced power consumption compared with active cabling options.
• Fan-out capability for flexible topologies: One QSFP56 end to two QSFP56 connectors on the opposite side enables streamlined connections from a single host port to dual NICs, switches, or high-performance storage adapters, simplifying cabling in dense racks.
• Optimized length and safety for data centers: The 3-meter length provides generous reach in standard racks while minimizing excess cabling. The LSZH jacket minimizes smoke and halogen emissions, contributing to safer data-center environments and easier compliance with safety standards.
• TAA compliant and enterprise-friendly: Built to meet Trade Agreements Act requirements, ensuring compatibility with government and enterprise procurement processes and simplifying supplier qualification for large-scale deployments.

How to Install Mellanox MCP7H50-H003R26

• Power down all devices before handling the cable to prevent electrostatic discharge or damage to ports.
• Identify the correct QSFP56 ports on each device in your InfiniBand HDR fabric; confirm the port type and alignment before insertion.
• Connect the QSFP56 end to the host or switch port, ensuring the connector clicks securely into place and latches are fully engaged.
• Attach the fan-out end to the two QSFP56 ports on the destination devices, taking care to align and seat each connector firmly without forcing.
• Maintain proper cable management to avoid sharp bends or kinks; observe recommended bend radii to preserve signal integrity and longevity.
• Power up the equipment and verify link status, negotiated speed, and error counters through the system BIOS/firmware or vendor network management tools; monitor for stability during initial runs.
