N9K-C9336PQ - Cisco Nexus 9000 Series Switch

N9K-C9336PQ Hardware Identity

N9K-C9336PQ identifies the Cisco Nexus 9336PQ, a fixed 2-RU ACI spine switch in the Nexus 9300 ACI spine. Cisco documents 36 fixed 40G QSFP+ ports. Optional modules, optics, cables, licenses and support are included only when explicitly itemized.

ACI 40G spine-port reserve

Assign each of the thirty-six QSFP+ positions to a leaf, border leaf, service connection or reserved capacity role. This product is documented as an ACI spine, so APIC release compatibility and fabric policy are essential purchase facts. Calculate ECMP capacity with one spine or link unavailable and retain enough unused positions for maintenance. A migration plan should identify which 40G optics or breakouts can be reused and how leaf links will transition to a 100G-era spine without creating a mixed-speed bottleneck.

Acceptance test

Verify APIC discovery, bring up leaf links across the port range, remove one fabric path and record endpoint reachability plus convergence.

Lifecycle boundary

Cisco has published lifecycle guidance for this first-generation 40G spine; verify APIC compatibility and migration to a current 100G-capable spine.

Receiving controls

• Match the exact PID, serial, installed modules, airflow and power configuration.
• Record every port personality, optic, cable, breakout and peer relationship.
• Confirm NX-OS or ACI mode, image checksum, license and controller compatibility.
• Attach failure-test evidence and a dated migration decision to the asset record.
