FAQs

Q: Can I run one port at 25G and the other at 10G?
A: Yes, ports can operate independently at 10G or 25G when supported by optics/DAC and the connected switch.

Q: Does this card include transceivers?
A: Transceivers or DAC cables are typically sold separately; select SFP28 (for 25G) or SFP+ (for 10G) according to your needs.

Q: Is SR-IOV enabled by default?
A: SR-IOV requires platform and OS support and may need to be enabled in system firmware and drivers.

Q: Will it work in a PCIe Gen4 slot?
A: Yes, PCIe is backward/forward compatible. The adapter will operate at PCIe Gen3 speeds.
