FAQs

Q: Will it work with existing copper cabling?
A: Yes. For 10G operation use Cat6a (or better) up to 100 meters; it also supports 1G on Cat5e/Cat6.

Q: Does it support SR‑IOV?
A: Yes. SR‑IOV is supported for virtualization; ensure it is enabled in BIOS and the OS driver.

Q: Can I mix 10G and 1G links across the four ports?
A: Yes. Each port negotiates speed independently with the connected switch.

Q: Are RJ45 cables included?
A: No. Patch cables are sold separately.

Q: Is link aggregation supported?
A: Yes. Teaming/LACP support is provided via the OS and driver.
