FAQs

Q: Does this switch provide PoE on the 10GBASE-T ports?
A: No. The 1/10GBASE-T ports are data-only and do not provide PoE.

Q: Can the 40G QSFP+ uplinks be broken out into 4x10G?
A: Yes. QSFP+ ports support 4x10G breakout with compatible DAC/AOC or optics and fanout cables.

Q: What license tier is included?
A: This configuration ships with the Base feature set under NX-OS. Enhanced L3 can be added with the appropriate license.

Q: Which airflow direction does this unit use?
A: Airflow direction is SKU-specific (BA = port-side intake; FA = port-side exhaust). Check the exact airflow suffix on your unit.

Q: What optics are supported on QSFP+?
A: Standards-based 40G QSFP+ modules such as SR4 and LR4 are supported, plus 4x10G breakout where applicable. Always validate transceiver compatibility with the platform support matrix.
