About the NVIDIA Mellanox MAM1Q00A-QSA56
The NVIDIA Mellanox MAM1Q00A-QSA56 is a hot-swappable QSFP56 to SFP56 port adapter (QSA56) that fits a QSFP56 port and accepts an SFP-type module, so the port can run a 50 Gbps (or 25/10/1 Gbps) link. The QSA56 let a 200GbE QSFP56 port accept an SFP56 / SFP28 / SFP+ module for a 50G or slower link; NVIDIA has since replaced it with the QSA28. Typical uses: 50GbE server connectivity on ConnectX-6 Lx / Dx and SFP56 switch ports.

MAM1Q00A-QSA56: frequently asked questions
What is the NVIDIA Mellanox MAM1Q00A-QSA56?
The MAM1Q00A-QSA56 is a QSFP56 to SFP56 port adapter (QSA56) from NVIDIA's LinkX range. It plugs into a QSFP56 port on an NVIDIA / Mellanox switch or adapter and holds one SFP-type module, so that port can run a 50 Gbps (or 25/10/1 Gbps) link. It is used for 50GbE server connectivity on ConnectX-6 Lx / Dx and SFP56 switch ports.
What is the NVIDIA SKU for the MAM1Q00A-QSA56?
NVIDIA's current ordering number for the MAM1Q00A-QSA56 is 980-9I79O-00G000. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN MAM1Q00A-QSA56. They are the same module; quote either and we will match it.
Which modules can I insert in the MAM1Q00A-QSA56?
Any SFP-type module the port adapter class supports: SFP56 / SFP28 / SFP+ modules. Reach, wavelength and connector then depend on that module, not on the adapter.
Is the MAM1Q00A-QSA56 compatible with my NVIDIA / Mellanox switch or adapter?
It works in NVIDIA and Mellanox platforms with QSFP-type ports that list this part in their firmware 'validated and supported cables and modules' table. Send us your switch / adapter model and firmware version and we check it against NVIDIA's support list before dispatch, so you only receive a module that links up in your port.
Is the MAM1Q00A-QSA56 still available?
NVIDIA has marked the MAM1Q00A-QSA56 legacy / end-of-life, so it is no longer in regular production. Next Gen Networks sources genuine new and surplus stock on request. Replaced by MAM1Q00A-QSA28; stock on request. Tell us the quantity and we will confirm availability, or suggest the current NVIDIA equivalent.
Is your MAM1Q00A-QSA56 genuine NVIDIA / Mellanox?
Yes. Next Gen Networks supplies original NVIDIA (Mellanox) LinkX parts, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch and we share serial numbers on request so you can verify them with mlxlink / mlxcables or the switch's transceiver inventory.
What is the MAM1Q00A-QSA56 price in India and how do I order?
The NVIDIA Mellanox MAM1Q00A-QSA56 price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number (or NVIDIA SKU 980-9I79O-00G000), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
