NVIDIA Mellanox® MTM005004 — Modular Switch Leaf Blank Filler Panel

Technical Identity
The NVIDIA Mellanox® MTM005004 is a passive leaf-slot blank filler panel for the NVIDIA Mellanox modular / director-class switch chassis family. It is a metal cover plate installed in empty leaf module bays of a half-populated director switch to maintain front-to-back airflow, prevent hot-air recirculation across the spine fabric cards, preserve EMI shielding integrity, and keep dust out of the unpopulated bay. The MTM005004 contains no active electronics, no fans, no PSU, and no fiber/copper interfaces — it is a chassis structural accessory.

Specifications

Brand: NVIDIA Mellanox
Manufacturer Part Number (MPN): MTM005004
Product type: Modular switch leaf-slot blank filler panel (passive)
Function: Airflow management, EMI containment, dust ingress prevention for unpopulated leaf bays
Slot type: Single leaf module bay cover
Active components: None — passive metal plate
Installation: Tool-less / single-screw retention into the leaf bay rails (chassis-dependent)
Hot-swap: Yes — can be installed or removed while chassis is powered (no electrical interface)
Power draw: 0 W
Cooling impact: Required for chassis to meet specified thermal envelope when leaf bays are not fully populated
Condition: Refurbished Grade A — bench-inspected by T.E.S IT-SOLUTIONS for fit, finish, and shielding gasket integrity


What This Is NOT

NOT a leaf line card. This is a blank filler — it has no ports, no ASIC, and provides no switching capacity. It cannot be used to add IB or Ethernet ports to a chassis.
NOT a fan tray or PSU. Despite being a chassis FRU, the MTM005004 contains no fans, no power components, and consumes no power.
NOT a standalone switch. It is only meaningful when installed in a compatible NVIDIA Mellanox modular / director-class chassis.
NOT for 1U fixed-form-factor switches. Fixed pizza-box switches (SN2000/SN3000/SN4000/QM8000/QM9000 series in 1U/2U) do not have leaf bays and do not accept this part.


Compatibility

Compatible with NVIDIA Mellanox modular / director-class InfiniBand and Ethernet chassis platforms (CS7500-series EDR director, CS8500-series HDR director, SX6536 / SX6512 modular switch families, and equivalent generations where the MTM005004 leaf blank is the OEM-specified filler part).
Verify before ordering: the leaf-bay blank part number is chassis-specific — always cross-reference your director chassis service manual or OEM spares matrix to confirm MTM005004 is the correct blank for your slot dimensions.
Required (per OEM thermal spec) whenever a leaf bay is left without a populated leaf module — operating a director chassis with open leaf bays causes airflow short-circuiting and may trigger thermal alarms.
No firmware, driver, or software interaction — pure mechanical part.


Frequently Asked Questions (FAQ)
Q. What exactly is the NVIDIA Mellanox MTM005004?
It is a passive metal blanking / filler panel that covers an empty leaf module bay in an NVIDIA Mellanox modular director-class switch chassis. Its job is airflow management, EMI containment, and dust protection — it adds no ports and no switching capability.
Q. Do I really need a blank filler for my empty leaf slots?
Yes. NVIDIA Mellanox director chassis are engineered for front-to-back airflow with all bays either populated or covered. Open bays cause hot exhaust air to recirculate into the cold aisle of the chassis, which raises ASIC junction temperatures on the populated leaves and the spine fabric cards. The OEM thermal spec assumes all bays are sealed.
Q. Will the MTM005004 fit any modular switch?
No. Blank filler panels are chassis-specific — slot dimensions and shielding gasket layouts differ between director-switch generations. Always verify against the spares matrix for your specific chassis (CS7500, CS8500, SX6536, SX6512, etc.) before ordering.
Q. Is this a fan or a power supply?
No. The MTM005004 is purely a passive mechanical part — no fans, no PSU, no electrical connection. It draws 0 W.
Q. Can I hot-swap it?
Yes. Because it has no electrical interface, the blank can be inserted or removed while the chassis is powered. However, leaving the bay open while the chassis is running will degrade cooling — minimize the open interval.
Q. What condition does T.E.S IT-SOLUTIONS supply?
Refurbished Grade A. Each unit is inspected for fit, finish, shielding gasket integrity, and absence of physical damage. Ships from EU stock in anti-static / protective packaging with worldwide B2B shipping options.

Why buy from T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS is a Europe-based NVIDIA Mellanox specialist serving HPC, AI, and enterprise data-center procurement teams since 2007. Chassis FRUs like leaf blanks, fan trays, PSUs, and rail kits are part of every director-class deployment — and they are exactly the parts that get lost in moves, RMAs, or partial reconfigurations. We keep these spares in EU stock, identify every unit by OEM part number before shipping, and offer free pre-sale verification against your chassis service manual so you do not end up with the wrong blank for your slot dimensions. Multi-currency B2B invoicing, EU stock with worldwide express options, and direct access to our networking engineers — not a generic call-center.
