A: Yes, when the host platform and optics/cables support 4x10G breakout, each QSFP+ port can fan out to four 10GbE links.

Q: Is a software license required?
A: Most deployments do not require an additional license for port activation, but verify your platform’s licensing policy.

Q: Can it be hot-inserted?
A: Yes, it is hot-swappable. Follow the platform’s recommended procedure for safe insertion and removal.

Q: Which optics are supported?
A: QSFP+ SR4/LR4 and compatible DAC/AOC cables are commonly supported; check the platform’s transceiver compatibility list.

Q: Will it affect switching performance?
A: No, it adds line-rate ports and leverages the host’s switching ASIC and features without reducing baseline performance.
