FAQs

Q: Can I run 10GbE on this adapter?
A: Yes, many deployments support 10GbE when used with 10G-capable SFP+ modules and compatible switches. Confirm downspeed support in your environment.

Q: Which cables or optics do I need?
A: Use SFP28 DAC/AOC cables for short runs or SFP28 optical transceivers for longer distances, matched to your switch ports and fiber type.

Q: Is SR-IOV supported on all OSes?
A: SR-IOV requires platform BIOS support and OS/hypervisor drivers. Check your OS and hypervisor documentation and enable it in BIOS if needed.

Q: Does this card support PXE boot?
A: Yes, PXE boot is commonly supported; ensure the correct firmware and BIOS settings are applied.

Q: Will this fit my server slot?
A: It uses a PCIe 3.0 x8 interface and low-profile bracket. Verify available slot type and bracket height in your UCS C890 M5 chassis.
