Description

IBM 00W0031 — Mellanox SX65xx-Series InfiniBand Chassis Switch Leaf Module (Service FRU)

Identity

This listing is for an OEM service part carrying the printed part number 00W0031, an IBM field-replaceable unit. The source basis for the identification below is a secondary-market listing that pairs 00W0029 and 00W0031 with IBM machine type/model 0724-HCM, described as an 18-port leaf module for the Mellanox SX65xx chassis switch family, together with the directly parallel and independently documented pairing of 00W0033 / 00W0035 for the SX65xx spine module (option number and FRU number for one part). On that basis 00W0031 is most likely the IBM service number for the SX65xx 18-port QSFP FDR leaf module of the MSX6001 family, with 00W0029 as its option number. T.E.S has not been able to corroborate this against an IBM or Mellanox parts document, and confirms the exact model from the unit label before dispatch.

Note for buyers who arrived here from a supplier list: 00W0031 is described in some stock records as a "Mellanox ConnectX-3 adapter". Research does not support that. Nothing found associates 00W0031 with a ConnectX-3 PCIe adapter card; the evidence points to a chassis switch module. This is stated plainly rather than quietly corrected.

What is confirmed about 00W0031

  • The printed part number is 00W0031, an IBM field-replaceable unit number.
  • It appears in the market alongside 00W0029 under IBM machine type/model 0724-HCM.
  • That 0724-HCM designation is described by the source as an 18-port leaf module for Mellanox SX65xx-series InfiniBand chassis switches.
  • The numbering pattern is consistent with the SX65xx spine module, whose IBM option number 00W0033 and IBM FRU number 00W0035 are documented together on a multi-OEM cross-reference (which also gives HPE 674282-B21, Dell A5063199 and IBM MTM 0724-HCN for that spine part).
  • The SX65xx chassis family that these modules populate comprises the Mellanox SX6506, SX6512, SX6518 and SX6536 InfiniBand chassis switches.
  • It is a plug-in chassis module, not a standalone switch and not a PCIe adapter card.

What is not yet confirmed

This list is deliberate. It is what T.E.S could not establish from documentation, and it is read off the physical unit before dispatch rather than guessed at here.

  • Whether this unit is a leaf module or a spine module. The two are not interchangeable and occupy different slots. Only the label and the physical connector face settle it.
  • Port count. The 18-port figure comes from a single secondary-market source and is not corroborated by vendor documentation.
  • InfiniBand generation. The SX65xx family spans FDR10 and FDR14; QDR, FDR10, FDR14, EDR, HDR and NDR are distinct generations and are not interchangeable. The generation of this unit is read off the label.
  • The specific Mellanox MSX6001 suffix (FR / FS / other) behind the IBM number, which distinguishes variants within the family including airflow direction.
  • Firmware level, and which chassis this unit was pulled from.

Request label photos before you order

Ask us for photographs of this unit's product label and we will send them before you commit to anything. There are 4 units of 00W0031 in this lot. Because the leaf-versus-spine question is the single thing that decides whether this part is useful to you, we will photograph the connector face and the full label of the specific units allocated to your order before you commit. If the label does not match what is described on this page, we say so and re-quote or cancel — we do not ship a substitute and hope it fits. Quote part number 00W0031 when you contact us.

Frequently asked questions

What exactly am I buying with 00W0031?

A refurbished IBM field-replaceable unit whose printed number is 00W0031. The available evidence — market listings pairing it with 00W0029 under IBM MTM 0724-HCM, and the parallel documented 00W0033/00W0035 pairing for the SX65xx spine module — points to a plug-in chassis switch module for the Mellanox SX65xx InfiniBand chassis family, most likely the 18-port QSFP FDR leaf. T.E.S could not corroborate that against a vendor parts document, so it is treated as unconfirmed and read from the label before dispatch.

Is 00W0031 a ConnectX-3 adapter card?

No evidence supports that. Some stock records describe 00W0031 as a Mellanox ConnectX-3 adapter, but nothing located in research connects 00W0031 to a PCIe adapter card of any generation. Everything found describes an SX65xx chassis module. If you need a ConnectX-3 adapter, do not order 00W0031 on the assumption that it is one — ask us for the label photograph first.

Will T.E.S confirm the exact model before shipping 00W0031?

Yes, as a standard dispatch step rather than on request. We read the printed part number, any Mellanox MSX600x number on the module, the port count and the generation marking off the physical unit. If it contradicts this page — in particular if it is a spine module rather than a leaf — we contact you before shipping.

What if 00W0031 turns out not to be the module I need?

Tell us the chassis (SX6506, SX6512, SX6518 or SX6536), the slot you are filling and the fabric generation you are running before you order. We check the unit against that first. If the label shows a different module, we re-quote or cancel; the identity risk is not passed to you silently. If a unit ships and we misread the label, it comes back at our cost.

Is the 00W0031 module tested?

It is cleaned, visually inspected and bench-tested where a suitable test topology is available. For a chassis module that depends on having a matching SX65xx chassis on the bench, which is not always the case. Ask what was actually done to the unit allocated to you and we will tell you rather than implying more than was done.

Can I get photographs of the 00W0031 label before I order?

Yes. Request label photos and we send images of the printed part number, any Mellanox module number, the connector face and the port count for the specific unit, before you commit. With 4 units in stock we can also check whether the lot contains more than one variant.

Why T.E.S IT-SOLUTIONS

T.E.S IT-SOLUTIONS supplies refurbished enterprise networking and server hardware from EU stock to a B2B market. On OEM service parts whose exact model is not established by the part number alone, we publish what we can verify and name what we cannot, instead of filling the gap with plausible-sounding specifications. Every unit is photographed and its label read before dispatch. If the unit differs from this page, we tell you before we ship. See tes-itsolutions.com.

Condition

Condition: Refurbished. Cleaned, visually inspected and bench-tested where a suitable test topology is available. EU stock, global B2B shipping. Final pricing for 00W0031 is subject to confirmation of the exact model: if the label identifies a higher- or lower-specification variant than described above, we contact you and re-quote or cancel rather than shipping a mismatch.
