FAQs

Q: What deployment scenarios is the N9K-C92300YC best suited for?
A: The N9K-C92300YC is designed for high-density 25G/100G data center fabrics, particularly spine-leaf architectures, cloud-scale environments, enterprise data centers, service provider hosting, and virtualized workloads requiring low latency and high throughput.

Q: Does this switch require a separate software license?
A: The N9K-C92300YC runs Cisco NX-OS Base software, which is included with the switch. Advanced features such as enhanced Layer 3 routing, VXLAN, or additional automation capabilities may require optional Essentials or Advantage licenses depending on your deployment needs.

Q: Can the SFP28 ports operate at both 10G and 25G speeds?
A: Yes, all 48 SFP28 ports support 1/10/25 Gigabit operation, providing flexible connectivity for mixed-speed environments. The 18 QSFP28 uplink ports can operate at either 40G or 100G speeds.

Q: What power supply options are available for this switch?
A: The N9K-C92300YC supports dual redundant hot-swappable power supplies, including 650W AC, 930W DC, and 1200W HVAC/HVDC options. Power supplies are sold separately and you can mix airflow directions to match your data center cooling design.

Q: Is this switch end-of-life?
A: Yes, Cisco announced end-of-sale for the N9K-C92300YC in January 2023. However, it remains a popular choice for refurbished deployments and continues to receive software support through its published end-of-life timelines. Contact us for current availability and support details.
