Identity

The NVIDIA Mellanox® MCP7904-X002A is a QSFP 40GbE 2m Passive Copper DAC Cable. This is a splitter / breakout cable assembly. 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 1-to-1 cable. This is a splitter/breakout — both endpoints on the split side must accept the lower-speed downstream connector.
  • 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

  • Primary connector: QSFP (compliant with MSA cage spec).
  • Downstream connectors: 2 × SFP+ on the split side.
  • Reach: 2m fixed length.
  • Speed: 40GbE.
  • Compatible adapters: ConnectX-3 Pro / ConnectX-4 / ConnectX-5.
  • Compatible switches: NVIDIA Spectrum / SwitchX-2.
  • 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.
  • Fan-out: one switch port serves two lower-speed endpoints.

Frequently Asked Questions (FAQ)

Q. What is the MCP7904-X002A?
The MCP7904-X002A is a 2m passive copper breakout cable: one QSFP head at 40GbE breaks out into four SFP+ legs at 10GbE each.

Q. Does the switch need special configuration?
Yes. The head port must be configured for 4x10GbE breakout mode.

Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MCP7904-X002A before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit and verifies vendor markings before dispatch from EU stock.
