FAQs

Q: Does it ship in Ethernet or InfiniBand mode?
A: It ships in InfiniBand mode (XDR 800Gb/s) by default and can be reconfigured to operate as 2x400GbE.

Q: What PCIe version is required?
A: It fits a standard PCIe x16 slot; achievable throughput depends on system PCIe bandwidth and platform design.

Q: Which transceivers or cables are supported?
A: Use vendor-qualified 400G/800G optics or compatible DAC/AOC for the specific cage type and mode; verify module compliance with your platform.

Q: Is firmware field-upgradeable?
A: Yes. Firmware can be updated using standard management tools to enable features and improvements.
