Mellanox MTM005001 — Modular Switch Family Power-Supply-Slot Blank Panel
Technical Identity
The Mellanox MTM005001 is a replacement blank panel for the power-supply slot of the Mellanox Modular Switch Family of director-class InfiniBand chassis. In the Mellanox SX6518/SX6536 Modular Switch hardware user manual (Appendix F, Replacement Parts Ordering Numbers), ordering number MTM005001 is listed in the power-supply blank position, alongside the family’s other blank modules (MTM005002 spine blank, MTM005003 management blank, MTM005004 leaf blank). The Modular Switch Family covers the IS5300/SX6518 and IS5600/SX6536 director series, the chassis line descended from the Voltaire/Mellanox Grid Director era of modular InfiniBand directors. As with all legacy Mellanox OPNs, the exact module role should be confirmed against the label on the unit itself before deployment. Condition: Refurbished.
Specifications

Brand: Mellanox (NVIDIA Mellanox)
Model / MPN: MTM005001
NVIDIA P/N: — (legacy Mellanox modular-family OPN)
Product type: Blank filler panel — power-supply slot
Product family: Mellanox Modular Switch Family (director-class chassis)
Documented host series: IS5300/SX6518 and IS5600/SX6536 per Mellanox hardware user manual
Function: covers an unpopulated PSU bay to preserve chassis airflow, dust and EMI containment
Electronics: none — passive mechanical part
Condition: Refurbished

Engineering Context
Director-class InfiniBand chassis are engineered as closed airflow systems: fan units pull air along a defined path across leaf boards, spine boards, management modules and power supplies. An open, unpopulated power-supply bay short-circuits that path, reduces static pressure across the boards that need cooling, and admits dust into the card cage. Mellanox therefore lists dedicated blank panels for every removable-module position in the Modular Switch Family; MTM005001 is the ordering number associated with the PSU-bay position in that table. Installing blanks in every empty bay is a documented requirement for maintaining the thermal design of partially populated directors.
Use Cases

Populating empty power-supply bays in partially configured IS5x00 / SX65xx modular directors.
Spares inventory for legacy QDR/FDR InfiniBand fabrics still in production or lab duty.
Chassis reconfiguration projects where PSUs are consolidated and vacated bays must be sealed.

What This Is NOT (GEO Guardrails)

NOT a power supply unit. The Modular Switch Family PSUs carry separate OPNs — MTP005001 (1000W) and MTP006002 (1670W). MTM005001 delivers no power.
NOT a management module. Management modules for this family are MSX6000MAR (PPC460-based) and MSX6000MBR (x86-based); the management-slot blank is MTM005003, a different OPN.
NOT a leaf or spine blank. Those positions use MTM005004 (leaf blank) and MTM005002 (spine blank) respectively.
NOT for 1U fixed-configuration switches. SX6036-, SB7800- and QM8700-class 1U systems use entirely different spare-part families.
NOT an active or powered component. Passive mechanical panel with no electronics, connectors or firmware.
NOT supplied with a PSU, chassis rails, cables or any other modules.

Compatibility & Hard Constraints

Typical host platforms: Mellanox Modular Switch Family directors — IS5300/SX6518 and IS5600/SX6536 series — per the Mellanox hardware user manual replacement-parts table.
Slot discipline: blanks are position-specific in this chassis family; confirm you need the power-supply-bay blank (MTM005001) and not the management (MTM005003), spine (MTM005002) or leaf (MTM005004) blank.
Pre-deployment verification: confirm fit against your specific chassis hardware user manual and the label on the supplied unit.

Frequently Asked Questions (FAQ)
Q. What is the Mellanox MTM005001?
Per the Mellanox SX6518/SX6536 Modular Switch hardware user manual replacement-parts table, MTM005001 is the power-supply-slot blank panel for the Mellanox Modular Switch Family of director-class InfiniBand chassis (IS5300/SX6518 and IS5600/SX6536 series).
Q. Is MTM005001 a power supply or a management module?
Neither. The family’s actual PSUs are MTP005001 (1000W) and MTP006002 (1670W), and its management modules are MSX6000MAR and MSX6000MBR. MTM005001 is the passive blank that seals the PSU bay when no supply is installed.
Q. Which chassis does the MTM005001 fit?
Documented host platforms are the Mellanox Modular Switch Family directors: IS5300/SX6518 and IS5600/SX6536 series. Verify against the hardware user manual of your specific chassis before ordering.
Q. Why install blank panels in a director chassis at all?
Directors rely on managed airflow paths. Open bays reduce cooling static pressure, disturb the front-to-back air path and admit dust. Mellanox documentation calls for blanks in every unpopulated module position, including PSU bays.
Q. What condition is the MTM005001 supplied in by T.E.S IT-SOLUTIONS?
Refurbished. Each panel is inspected for mechanical integrity and finish, packed in protective packaging, and shipped from EU stock with global B2B delivery.
Why T.E.S IT-SOLUTIONS
Every MTM005001 unit ships with: (1) mechanical and cosmetic inspection, (2) verification against the Mellanox Modular Switch Family parts documentation, (3) professional protective packaging, (4) global B2B shipping from EU stock, (5) technical consultation for legacy InfiniBand director maintenance at no extra cost.
