Mellanox SCRPNMNG-ES2F — SCORPION 36-Port QSFP28 EDR 100Gb/s Managed InfiniBand Switch, Engineering Respin
Technical Identity
The Mellanox SCRPNMNG-ES2F is an engineering / internal-use build from the Mellanox SCORPION switch program: a 36-port QSFP28 EDR 100Gb/s managed InfiniBand switch with two power supplies, standard depth and P2C airflow, carrying a respin CPU and based on the MSB7700-ES2F revision A7 design. The unit is marked FOR INTERNAL USE. Protocol: InfiniBand EDR. Condition: Refurbished.
Engineering status, stated plainly. SCRPNMNG-ES2F is an engineering respin, not a general-availability SKU. It carries no NVIDIA or Mellanox support entitlement, no manufacturer warranty and no vendor RMA or firmware-update path. The CPU respin means control-plane hardware differs from the shipping MSB7700-ES2F, so management-software behaviour must be validated on the unit itself. Sold for laboratory, spares and evaluation use only.

Engineering Context
EDR InfiniBand runs 25Gb/s per lane with 64/66 encoding over four lanes, producing the 100Gb/s per-port figure quoted for the MSB7700 platform behind SCRPNMNG-ES2F. SCORPION is the Mellanox internal program name for this generation of 36-port EDR systems. A CPU respin is a control-plane change, usually driven by component availability or a silicon erratum; it does not alter the InfiniBand data path but it can change which management-software builds boot cleanly. T.E.S also stocks SS-SCORPION3 and SS-SCORPION6 units as separate listings — different builds, not interchangeable with SCRPNMNG-ES2F.
Use Cases

Laboratory and test-bench EDR 100Gb/s InfiniBand fabrics where vendor support is not required.
Non-critical spares for an existing SB7700-class EDR estate, accepting control-plane differences.
Training rigs, protocol development and fabric-software validation.

What This Is NOT

NOT a GA SKU. SCRPNMNG-ES2F is an engineering respin marked FOR INTERNAL USE. The general-availability equivalent is MSB7700-ES2F.
NOT covered by NVIDIA support or warranty. No support entitlement, RMA path or firmware-update entitlement applies.
NOT identical to a shipping MSB7700-ES2F. The respin CPU changes the control plane, so management-software compatibility must be validated on the unit.
NOT an FDR, HDR or NDR switch. Per-port rate is EDR 100Gb/s. FDR is SwitchX-2, HDR needs Quantum, NDR needs Quantum-2.
NOT a QSFP+, QSFP56 or OSFP switch. QSFP28 cages only.
NOT a C2P-airflow unit. This build is P2C; installing it in a rack plumbed for C2P will fight the rack airflow.
NOT supplied with QSFP28 transceivers, DAC/AOC cables, rail kits or spare power supplies.

Compatibility & Hard Constraints

Typical fabric endpoints: Mellanox ConnectX-4 and ConnectX-5 EDR 100Gb/s QSFP28 host adapters and OEM-branded equivalents.
Typical cabling: QSFP28 EDR passive copper DAC and EDR active optical cable. Verify cable profile recognition in the switch CLI.
Airflow: P2C only on this build. Match it to the rack and to neighbouring switches before installation.
Firmware and management: the installed image is an engineering build and upgrade paths through NVIDIA channels are not available. Validate subnet-manager and management-plane behaviour on the unit itself.
Pre-deployment verification: board revision, CPU respin implications for the intended management stack, firmware build, PSU population, airflow.

Frequently Asked Questions (FAQ)
Q. What is the Mellanox SCRPNMNG-ES2F?
An engineering respin from the Mellanox SCORPION program: a 36-port QSFP28 EDR 100Gb/s managed InfiniBand switch, 2 power supplies, standard depth, P2C airflow, based on the MSB7700-ES2F revision A7 design and marked FOR INTERNAL USE.
Q. Is SCRPNMNG-ES2F a production part number?
No. It is an internal engineering build. The GA equivalent is MSB7700-ES2F: 36-port QSFP28 EDR 100Gb/s managed, 7.2Tb/s non-blocking, 90ns switch latency.
Q. Does SCRPNMNG-ES2F carry NVIDIA warranty or support?
No. No NVIDIA or Mellanox support entitlement, no manufacturer warranty and no vendor RMA path. T.E.S sells it for laboratory, spares and evaluation use only.
Q. What does the respin CPU change?
It changes control-plane hardware relative to a shipping MSB7700-ES2F. The InfiniBand data path is unchanged, but which management-software builds boot and run cleanly must be validated rather than assumed.
Q. What connector and airflow does SCRPNMNG-ES2F use?
36 x QSFP28 cages at EDR 100Gb/s per port, P2C airflow. QSFP+ FDR, QSFP56 HDR and OSFP NDR modules are not compatible, and this build is not a C2P unit.
Q. How does SCRPNMNG-ES2F relate to the SS-SCORPION3 listing?
Both come from the SCORPION program but are different builds with different part numbers. T.E.S stocks them as separate listings; they are not interchangeable.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. The unit is powered up and inspected where test topology is available, with port checks, label and firmware-build verification, cosmetic inspection and anti-static packaging. EU stock, global B2B shipping.
Why T.E.S IT-SOLUTIONS
Every unit ships with: (1) power-on verification where test topology is available, (2) label, board-revision and firmware-build check, (3) cosmetic inspection, (4) anti-static packaging, (5) global B2B shipping from EU stock, (6) honest disclosure of internal-use status before purchase.
Condition
