FAQs

Q: What is the difference between this spare unit and the standard configuration?
A: The N9K-C93240YC-FX2 spare unit does not include power supplies or fan modules. These components must be ordered separately. Standard configurations typically include dual redundant power supplies and fan trays as part of the base SKU.

Q: Can this switch operate in both ACI and NX-OS modes?
A: Yes, the Nexus 93240YC-FX2 supports both Cisco ACI (Application Centric Infrastructure) fabric mode and standalone NX-OS mode. The operating mode is configured during initial setup and can support VXLAN EVPN fabrics in both deployment models.

Q: What transceivers are required for the SFP28 and QSFP28 ports?
A: The 48 SFP28 ports support 1G, 10G, and 25G transceivers, while the 12 QSFP28 ports support 40G and 100G modules. Cisco recommends using genuine Cisco optics for full feature support and warranty coverage. Third-party optics may work but are not officially supported.

Q: Is this switch suitable for a spine-leaf data centre architecture?
A: Absolutely. The 93240YC-FX2 is designed as a high-density leaf switch, offering 48x 25G ports for server connectivity and 12x 100G uplinks to connect to spine switches. It's ideal for modern data centres requiring low-latency, high-throughput east-west traffic.

Q: Does this model support port breakout on the QSFP28 uplinks?
A: The 93240YC-FX2 does not natively support breakout cables on the QSFP28 ports, though this feature has been on Cisco's roadmap. The 48 SFP28 ports are fixed and do not support breakout. Always consult the latest NX-OS release notes for feature availability.
