FAQs

Q: Can I mix speeds on different ports?
A: Yes. Ports auto-negotiate to 32/16/8/4 Gbps, allowing mixed-speed operation per port.

Q: Is NVMe/FC supported on this module?
A: Yes. It supports NVMe/FC for modern, high-performance storage fabrics.

Q: Which optics should I use for 32G operation?
A: Use 32G FC SFP28 transceivers to achieve full 32G speeds.

Q: Does it require specific licenses for advanced features?
A: Some features, such as Inter-VSAN Routing, require additional NX-OS licenses.

Q: What chassis does it fit?
A: It fits Cisco MDS 9700 series directors, including the 9706, 9710, and 9718.
