FAQs

Q: What operating systems does the N9K-C9336C-FX2 support?
A: The switch supports both Cisco NX-OS for traditional data center deployments and Cisco ACI mode for intent-based, policy-driven network automation. You can choose the operating mode based on your network architecture requirements.

Q: Can this switch support lower-speed connections like 10G or 25G?
A: Yes, all 36 QSFP28 ports support full breakout capabilities. You can use breakout cables to connect 4x25G or 4x10G devices per port, significantly increasing port density. The switch supports 1/10/25/40/50/100 Gbps speeds with appropriate optics and cables.

Q: What airflow options are available for the N9K-C9336C-FX2?
A: The switch offers reversible airflow configurations to match your data center cooling design. You can order port-side intake (burgundy colored) or port-side exhaust (blue colored) fan and power supply modules. All fan modules and power supplies must have matching airflow direction.

Q: Is this switch suitable for spine or leaf deployment in a data center fabric?
A: Yes, the N9K-C9336C-FX2 is designed for both spine and leaf roles in modern data center architectures. With 36 high-speed ports, 7.2 Tbps capacity, and sub-microsecond latency, it excels in spine-leaf topologies, VXLAN EVPN fabrics, and ACI deployments.

Q: What type of transceivers are required?
A: The switch uses QSFP28 transceivers for 100G links and QSFP+ transceivers for 40G connections. For breakout configurations, you can use QSFP28-to-4xSFP28 cables for 25G or QSFP+-to-4xSFP+ cables for 10G. Ensure you use Cisco-compatible optics for full feature support.
