FAQs

Q: Which transceivers or cables are compatible?
A: Use QSFP28 modules or DAC/AOC cables qualified for the adapter and server platform (e.g., 100G SR4/LR4, or passive/active QSFP28 DAC/AOC).

Q: Does it support breakout to 4x 25G?
A: Downshift and breakout capabilities depend on platform and firmware support. Verify your server’s documentation for supported configurations.

Q: What drivers are required?
A: Use the Intel E810 family driver set appropriate for your operating system. Refer to the OS and platform support matrices.

Q: What slot do I need?
A: A high-bandwidth PCIe slot (Gen4 recommended) with adequate lane width and cooling is required to achieve full performance.
