Mellanox SS-NEPTUNE1 - Neptune Engineering Sample, 36-Port QSFP Class
Technical Identity
SS-NEPTUNE1 is the code exactly as printed on the unit. It is a Mellanox engineering sample carrying the internal codename Neptune. The owner stock record describes it as a 36-port QSFP QDR InfiniBand switch of the SX6790 class. T.E.S presents that as a described specification with a stated evidence basis, not a verified fact, and specifically does not confirm the QDR generation.
Engineering-sample, pre-production and unverified-part-number hardware carries no NVIDIA / Mellanox support entitlement, no manufacturer warranty, no vendor firmware entitlement and no RMA path. Sold for lab, spares and evaluation use.

Engineering Context
The Neptune codename has a real evidence trail. Marketplace listings exist for a Mellanox Neptune MSX6790 36-port InfiniBand switch, tying the name to the MSX6790 platform, and the T.E.S catalogue holds NPTNMNG-FS2F2 and NPTNBBU-FS2F2 units using the same NPTN naming. That supports the 36-port QSFP description but does not settle the generation: MSX6790 is a SwitchX-2 platform and public listings describe it variously as QDR 40Gb/s and FDR 56Gb/s. Do not assume QDR - confirm from the label.
What is known
The code SS-NEPTUNE1 is printed on the unit, physically in T.E.S EU stock.
The internal codename associated with the unit is Neptune.
Marketplace listings tie the Neptune name to the Mellanox MSX6790 36-port platform. These are marketplace listings, not NVIDIA documents.
What is not yet confirmed
The InfiniBand generation. QDR 40Gb/s and FDR 56Gb/s are both associated with this platform family publicly.
That SS-NEPTUNE1 is in fact 36-port. It is described, not verified.
Any equivalence to MSX6790, SX6790, SX6720 or any production part number.
Whether the unit is managed or externally managed.
Request Label Photos
T.E.S IT-SOLUTIONS photographs the regulatory label, serial number and board markings on this exact unit before dispatch. Request photos before you commit. Pricing is subject to confirmation of the exact unit.
Use Cases
Laboratory and bench work where an unsupported QSFP-class sample switch is acceptable.
Repair-donor and spares harvesting for QSFP cages, PSUs and fan trays.
Evaluation buys where the purchaser will verify port count and generation themselves.
What This Is NOT
NOT a supported production unit. SS-NEPTUNE1 was never released as a documented, supported product under this code.
NOT covered by warranty or RMA. No manufacturer warranty, no advance replacement, no vendor support route.
NOT supplied with firmware, licences, MLNX-OS entitlement or vendor documentation.
NOT equivalent to any production model. No mapping from SS-NEPTUNE1 to a shipping part number is implied.
NOT specified for ports, speed, connector or protocol. No port count, Gb/s figure or cage type is claimed.
NOT supplied with rails, brackets, transceivers, cables or PSUs unless confirmed for the unit.
Compatibility & Hard Constraints
No compatibility list is published. T.E.S does not state platform compatibility for an unverified unit.
Identity verification is the buyer gate. Model, ports, speed, connector and protocol must be read off the unit first.
Connector-family caution: OSFP, QSFP-DD, QSFP56, QSFP28, QSFP+ and SFP cages are not interchangeable.
Generation caution: QDR, FDR, EDR, HDR and NDR are not interchangeable, nor Ethernet speed grades with InfiniBand generations.
Pre-deployment verification: firmware and licence state are unknown. Do not buy SS-NEPTUNE1 for a production fabric.
Frequently Asked Questions (FAQ)
Q. What exactly am I buying when I order SS-NEPTUNE1?
One physical unit marked SS-NEPTUNE1, held in the EU. It is a Mellanox Neptune engineering sample described as a 36-port QSFP InfiniBand switch, generation unconfirmed. Hardware only - no documented model, specification sheet, firmware, licence, warranty or support entitlement.
Q. Is SS-NEPTUNE1 a production unit?
No. SS-NEPTUNE1 is pre-production engineering-sample hardware. It is not MSX6790, SX6790, SX6720 or any other production model, and no such equivalence is asserted. It carries no support entitlement, no warranty and no RMA path.
Q. Will you confirm the model before shipping SS-NEPTUNE1?
T.E.S photographs the SS-NEPTUNE1 code, label, serial and board markings before dispatch, and will count and photograph the physical ports. If the label states an InfiniBand generation or licensed speed, T.E.S will read it off and pass it to you unedited - the only reliable way to settle QDR versus FDR here.
Q. Is SS-NEPTUNE1 tested?
SS-NEPTUNE1 receives visual inspection and label photography. Functional testing is limited by the absence of vendor firmware and documentation, so do not assume it has been validated. Where a rig is available T.E.S will attempt a power-on check on request and report the result honestly, including a negative result.
Q. Can I get photos of the regulatory label on SS-NEPTUNE1?
Yes. Request label photographs before ordering and T.E.S will photograph the label, serial number and chassis markings on the actual SS-NEPTUNE1 unit that would ship. Pricing is subject to confirmation of the exact unit.
Q. How is SS-NEPTUNE1 different from your other Neptune units?
They are different physical units. NPTNBBU-FS2F2 is listed as a pre-GA SX6720 and NPTNMNG-FS2F2 as a Neptune 36-port QSFP FDR managed switch, each with its own stock and pricing. SS-NEPTUNE1 is a separate engineering sample, quantity 1, cross-referenced rather than merged.
