FAQs

Q: Does this switch support Power over Ethernet?
A: No, the N9K-C93108TC-FX does not support PoE. It is designed as a high-density data centre switch for server and storage connectivity, not for powering endpoints.

Q: What licensing is required for this switch?
A: The N9K-C93108TC-FX requires either NX-OS Essentials or NX-OS Advantage software licenses for standalone mode, or ACI Essentials/Advantage licenses for ACI fabric deployments. Licenses are sold separately and are typically subscription-based.

Q: Can the 48 BASE-T ports run at different speeds simultaneously?
A: Yes, each of the 48 RJ-45 ports can auto-negotiate and independently run at 100 Mbps, 1 Gbps, or 10 Gbps, making it ideal for mixed-speed environments and staged migration from legacy infrastructure.

Q: Is MACsec encryption supported on all ports?
A: MACsec wire-rate encryption is supported on ports operating at 10 Gbps and higher, including the 48 BASE-T ports when running at 10G and all six QSFP28 uplink ports at 40G or 100G.

Q: What deployment scenarios is this switch best suited for?
A: The N9K-C93108TC-FX is ideal for top-of-rack deployments in data centres with existing copper cabling infrastructure. It excels in VXLAN EVPN fabrics, ACI environments, and brownfield upgrades where CAT6/CAT6A cabling is already in place.
