FAQs

Q: Does the N9K-C93128TX support 1G speeds on the copper ports?
A: Yes. All 96 fixed ports are auto-sensing 100M/1G/10GBASE-T, allowing seamless connectivity with legacy 1G servers and future migration to 10G without infrastructure changes.

Q: Can this switch be deployed as a leaf switch in a Cisco ACI fabric?
A: Yes. The N9K-C93128TX is designed to function as a leaf switch in Cisco ACI environments, providing high-density server connectivity and integration with ACI spine switches for automated, policy-based data center operations.

Q: Which uplink modules are compatible with the N9K-C93128TX?
A: The switch supports various uplink modules including the N9K-M6PQ (6x 40G QSFP+), N9K-M12PQ (12x 40G QSFP+), N9K-M6PQ-E, and N9K-M4PC-CFP2 (4x 100G). With the N9K-C93128TX, 8 ports are active on the M12PQ module.

Q: What type of cabling is required for 10G connectivity?
A: For full 10 Gbps speeds over the standard 100-meter distance, Category 6a (Cat6a) or Category 7 (Cat7) cabling is required. Standard Cat6 cabling may support 10G at shorter distances (up to 37-55 meters).

Q: Does the N9K-C93128TX require additional licensing?
A: The switch includes base NX-OS software. Advanced features such as ACI mode or certain Layer 3 protocols may require additional licenses like Nexus 9300 Essentials or Advantage licenses, depending on deployment requirements.
