产品问答

Where does NVIDIA document Q3400-RA in an AI-cluster design?

The DGX B300 XDR SuperPOD components table names Q3400-RA order code 920-9B36F-00RX-8S0 for compute leaves and spines. It is a manufacturer reference architecture whose final bill of materials depends on the project; it is not a SwitchInfra customer-delivery claim.

Can I select a replacement by appearance or wattage alone?

Use the manufacturer replacement-parts table for the complete switch model and order code. Matching dimensions, connector shape or PSU wattage alone does not establish compatibility.

Does a power supply listing prove the required power cord is included?

Check the exact ordering row and quote. Some PSU rows explicitly include a cord; the Q3400-RA system ordering row explicitly excludes power cords. Cord region and electrical ratings still need checking.

Does a public ordering or compatibility entry prove stock and delivery?

No. Record the manufacturer’s published lifecycle wording separately from commercial availability. Stock, lead time, software entitlement, support and warranty require a current supplier quote.

How are Q3400-RA and Q3401-RD ports arranged?

Both are documented with 144 XDR data ports across 72 OSFP cages. NVIDIA also documents a separate fabric-management port, which should be considered separately in port planning.

What is the practical difference between Q3400-RA and Q3401-RD power?

The ordering table lists eight power supplies for Q3400-RA and 48 VDC busbar input for Q3401-RD. Both require the correct rack and cooling design; they are distinct purchase configurations.
