NVIDIA Mellanox® MTDF-CP-A — MCS75XX Director System Cable Supporter
Technical Identity
The NVIDIA Mellanox® MTDF-CP-A is a passive mechanical cable supporter accessory designed for the MCS75XX-series Director InfiniBand switch chassis (SwitchX-2 / FDR-class director platform). It provides structural cable strain relief and organized routing for high-density InfiniBand fabrics in the 648-port, 324-port, 216-port and 108-port MCS75XX director configurations, reducing bend-radius stress on QSFP+/QSFP14 copper and active-optical interconnects across leaf-to-spine cable bundles. Sold standalone as a spare / replacement part for chassis cable management kits. Condition: New factory-sealed.

What This Is NOT

NOT an InfiniBand cable, transceiver, leaf card, spine card or management module. No signal or protocol function.
NOT an active component. No power, no firmware, no PHY — purely mechanical strain relief.
NOT compatible with Quantum / Quantum-2 (QM87xx / QM97xx) director platforms — designed specifically for the older MCS75XX SwitchX-2 director generation.
NOT supplied with cables, AOCs, DAC harnesses, brackets or rail kits.

Compatibility & Constraints

Target chassis: NVIDIA Mellanox MCS75XX-series Director Switch — verified configurations: 648-port, 324-port, 216-port and 108-port.
Cable types supported: Standard QSFP+/QSFP14 passive copper (DAC), active copper, and active optical cables (AOC) used in MCS75XX director deployments.
Out of scope: Quantum (QM87xx HDR) and Quantum-2 (QM97xx NDR) director platforms use a different mechanical cable management system and are NOT compatible with MTDF-CP-A.
Pre-deployment: Confirm MTDF-CP-A revision matches your specific MCS75XX chassis revision and existing cable management hardware before ordering replacement units.

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MTDF-CP-A?
The MTDF-CP-A is a passive mechanical cable supporter for the NVIDIA Mellanox MCS75XX-series Director InfiniBand switch chassis. It provides cable strain relief and routing organization for the 648-port, 324-port, 216-port and 108-port MCS75XX director configurations. No electronic components.
Q. Does the MTDF-CP-A have any electronic or signal function?
No. MTDF-CP-A is a purely mechanical accessory — no power draw, no firmware, no PHY, no protocol function. It supports the cables physically; it does not carry traffic.
Q. Which director systems is MTDF-CP-A compatible with?
NVIDIA Mellanox MCS75XX-series Director Switch chassis in 648-port, 324-port, 216-port and 108-port configurations. It is NOT compatible with Quantum (QM87xx) or Quantum-2 (QM97xx) director platforms.
