Product questions & answers
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.
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.
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.
