Identity
The NVIDIA Mellanox® MCC4L30-002 is a 20GbE 2m Passive Copper DAC Cable. Refurbished Grade A — bench-tested in both link and signal-integrity checks by T.E.S IT-SOLUTIONS.
What This Is NOT
- NOT an AOC. Passive copper cable with limited reach (typically ≤7m for high-speed gens).
- NOT a transceiver. Fixed-length cable assembly; ends are not field-replaceable.
- NOT a splitter or breakout cable. 1-to-1 cable assembly only.
- NOT bundled with adapters or transceivers — sold standalone.
Capabilities & Features
- Passive copper twin-axial pairs — no power required, lowest latency.
- DDM (Digital Diagnostic Monitoring) — temperature, voltage, optical power readable via I²C.
- EEPROM on each end with product identification and operating data.
- Hot-pluggable into any matching QSFP/SFP cage.
Compatibility & Constraints
- Reach: 2m fixed length.
- Speed: 20GbE.
- Compatible adapters: NVIDIA ConnectX series.
- Compatible switches: NVIDIA Spectrum / Quantum (verify by speed).
- Power: drawn from host port (no external supply required).
Deployment & Use Cases
- Top-of-Rack to server interconnect.
- HPC compute node fabric.
- AI training cluster east-west bandwidth.
Frequently Asked Questions (FAQ)
Q. What is the MCC4L30-002?
The MCC4L30-002 is a 2m passive copper CX4 cable rated for InfiniBand DDR 20Gb/s.
Q. Will this work in QDR, FDR, EDR or HDR networks?
No. It is a legacy DDR-generation 20Gb/s CX4 cable, not compatible with later-generation QSFP-family InfiniBand fabrics.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MCC4L30-002 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) bench-tests each unit where test topology is available, before dispatch from EU stock.
Why T.E.S IT-SOLUTIONS
Every unit is bench-tested by T.E.S IT-SOLUTIONS: link establishment, port-by-port traffic validation, and full cosmetic inspection. Professional anti-static packaging, global B2B shipping from EU stock, and technical consultation for HPC / AI cluster deployments.
