FAQs

Q: Can I mix 800G and 400G in the same chassis?
A: Yes. Use QSFP-DD 800G for native 800G and break out to 2x400G or use supported 400G modules, subject to software support.

Q: Is ACI supported on this platform?
A: Yes, it can operate in NX-OS standalone mode or as part of an ACI fabric, depending on licensing and design.

Q: What breakout options are available?
A: Each 800G port can be broken out to 2x400G, 4x200G, or 8x100G where supported by optics and software.

Q: What cooling and power options are available?
A: The switch supports redundant, hot-swappable PSUs and fan trays. Select airflow orientation and PSU wattage appropriate for your site.

Q: Is it suitable for AI/ML clusters?
A: Yes. The 800G ports and 25.6Tbps switching make it well-suited for AI/ML, HPC, and large cloud fabrics.
