NVIDIA Mellanox® MSX6002TBS — SwitchX-2 36-Port FDR10 40Gb/s Blade Module for SX65xx Directors (dual P/N MIS5002QC)
Technical Identity
The NVIDIA Mellanox® MSX6002TBS is a SwitchX-2 based 36-port FDR10 40Gb/s VPI blade module for the Mellanox SX65xx family of director-class modular InfiniBand switches. It installs in a chassis blade slot and forms part of the internal switching fabric. The same board carries a second part number, MIS5002QC, used in the InfiniScale IV / IS5x00 QDR 40Gb/s chassis context (IS5100, IS5200, IS5600). This is a chassis module, not a standalone switch. Condition: Refurbished.
Per-unit flag: port count and the leaf-versus-spine role are printed on the board label. Channel catalogue data consistently describes MSX6002TBS as a 36-port FDR-10 spine for SX6500-series chassis, but the role and port count of the specific unit supplied must be confirmed from its label before ordering.

Engineering Context
Director-class InfiniBand chassis are built as a two-stage Clos fabric inside one enclosure: leaf blades terminate the external QSFP cabling, spine blades cross-connect the leaves. The MSX6002TBS sits in that internal stage. FDR10 runs 40Gb/s per port using 64/66 encoding — deliberately distinct from full FDR at 56Gb/s and from QDR at 40Gb/s with 8/10 encoding. T.E.S also stocks the MSX6002TBR (FDR10 spine) and MSX6002FLR (FDR14 / 56Gb/s class spine for SX6500); those are not interchangeable with an MSX6002TBS without checking chassis population rules and firmware level.
Use Cases

Replacement or spare fabric module for an in-service SX6506, SX6512, SX6518 or SX6536 director.
Replacement or spare module for an IS5100, IS5200 or IS5600 chassis where the board is labelled MIS5002QC.
Capacity population of a partly filled director chassis to raise internal bisection bandwidth.
Lab and staging spares for legacy FDR10 / QDR director estates.

What This Is NOT

NOT a standalone switch. The MSX6002TBS operates only inside a supported chassis. No independent power supply, management plane or external cable ports.
NOT an FDR 56Gb/s module. FDR10 is 40Gb/s per port. For FDR14 / 56Gb/s class spine capacity a different part number is required, such as MSX6002FLR.
NOT an EDR, HDR or NDR module. CS75xx, CS85xx and later director families use entirely different module part numbers.
NOT the same part number as MSX6002TBR. Different suffix, separate T.E.S listing — confirm the exact P/N printed on the board.
NOT usable in fixed 1U switches. SX6036, SX6710 and SX6720 are fixed-configuration systems and do not accept blades.
NOT supplied with a chassis, slot blanks, cables, rails or management modules.

Compatibility & Hard Constraints

Typical host chassis: Mellanox SX65xx directors (SX6506, SX6512, SX6518, SX6536) for the MSX6002TBS designation; IS5100, IS5200 and IS5600 for MIS5002QC.
Chassis population rules: module type, quantity and slot placement must follow the rules for the target system. Mixing FDR10 and FDR14 class modules in one chassis is not assumed to be supported.
Firmware: chassis management firmware must recognise the module revision. Verify module inventory and status in the chassis CLI after insertion.
Board label: confirm the printed part number (MSX6002TBS or MIS5002QC), board revision, port count and leaf/spine role before ordering.
Pre-deployment verification: chassis model, existing module population, chassis firmware level, module revision.

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MSX6002TBS?
A SwitchX-2 based 36-port FDR10 40Gb/s VPI blade module for Mellanox SX65xx director-class chassis switches. It is a hot-swappable internal fabric module, RoHS-6 compliant, and not a standalone switch.
Q. Why does this board have two part numbers, MSX6002TBS and MIS5002QC?
The same board family is designated MSX6002TBS in the SX65xx / FDR10 context and MIS5002QC in the InfiniScale IV IS5x00 / QDR 40Gb/s context. Which number is printed on a given board depends on the build, so check the label against the target chassis.
Q. Is FDR10 the same as FDR 56Gb/s?
No. FDR10 runs at 40Gb/s per port with 64/66 encoding; full FDR is 56Gb/s per port. For 56Gb/s class spine capacity a different SX65xx module such as MSX6002FLR is required.
Q. Which chassis accept the MSX6002TBS?
The Mellanox SX65xx director family: SX6506, SX6512, SX6518 and SX6536. As MIS5002QC the board is used in IS5100, IS5200 and IS5600. It does not fit CS75xx or CS85xx directors, or any fixed 1U switch.
Q. Is the MSX6002TBS a leaf blade or a spine blade?
Channel catalogue data consistently lists it as a 36-port FDR-10 spine for SX6500-series chassis. Because leaf and spine boards in this generation are closely related, the role and port count of the individual unit must be confirmed from the board label.
Q. Does the MSX6002TBS have external QSFP ports?
No. Fabric blades provide the internal switching stage; external QSFP cabling terminates on the chassis leaf blades, not on this module.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
