N9K-C9336C-FX2 Description
N9K-C9336C-FX2 is a Cisco Nexus 9336C-FX2 1RU fixed-port data center switch with 36 40/100G QSFP28 ports for Nexus 9000 leaf or compact high-speed fabric deployments.
This model fits orders that need a 36-port QSFP28 switch with Ethernet-focused 1/10/25/40/100G flexibility instead of the `-E` variant that Cisco documents with 16/32G Fibre Channel support. It also differs from N9K-C93360YC-FX2 by keeping every data port as QSFP28 rather than mixing dense SFP28 access ports with a smaller QSFP28 uplink set.
For price and stock checks, the main BOM risks are supported optics or QSA adapters, breakout mapping, port-side intake or exhaust airflow, matching fan and power supply direction, and the correct NX-OS or ACI software baseline.

Product Performance
Key Features
N9K-C9336C-FX2 uses a uniform QSFP28 port design across all 36 data ports. That matters when the rack plan is built around 40G or 100G optics, DACs, AOCs, or approved breakout designs.
Cisco documents the non-`-E` N9K-C9336C-FX2 as an Ethernet switch, while the N9K-C9336C-FX2-E variant adds 16/32G Fibre Channel support. Procurement should not substitute the two models when SAN convergence is part of the bill of materials.
The hardware guide confirms 10G QSA operation on ports 1-36 and 1G QSA operation on ports 7-32. A design that needs 1G fallback on edge ports should map those connections before the switch is quoted.
The platform can be used in Cisco NX-OS or Cisco ACI environments. The software image, license package, APIC connectivity, and fabric role should be aligned before the hardware order is released.
Cisco lists port-side intake and port-side exhaust choices for fans and power supplies. Fan modules and power supplies must use the same airflow direction to avoid a cooling mismatch in hot-aisle or cold-aisle racks.
The switch uses three fan modules and two power supply modules with one power supply for operation and one for redundancy. Power source type and airflow color should be checked together because Cisco warns against mixing AC and DC power sources.
Application Scenarios
Deploy N9K-C9336C-FX2 where the design calls for a compact Nexus switch with 36 QSFP28 ports and 7.2 Tbps switching bandwidth. It is a better match than SFP28-heavy FX2 models when the port plan is primarily 40G or 100G.
Select this SKU for projects that have already chosen Cisco Nexus 9000 operations in ACI mode or standard NX-OS mode. The quote should include the image baseline and the license package that matches the intended feature set.
Use the documented QSA support when a 40G or 100G fabric still needs selected 10G connections. The 1G QSA limit is narrower, so ports 7-32 should be reserved if any 1G QSA links are required.

- In a N9K-C9336C-FX2 vs N9K-C9336C-FX2-E comparison, the key difference is FC capability: the `-E` model supports 16/32G Fibre Channel, while N9K-C9336C-FX2 is the Ethernet-focused 36-port QSFP28 option.
- The N9K-C9336C-FX2 difference from N9K-C93360YC-FX2 is port layout and form factor; N9K-C9336C-FX2 keeps 36 QSFP28 ports in 1RU, while N9K-C93360YC-FX2 uses a 2RU layout with 96 SFP28 ports and 12 QSFP28 ports.
- For buyers comparing which model to choose, N9K-C9336C-FX2 is the comparison point when the BOM asks for a compact 36-port QSFP28 Nexus 9300-FX2 switch without documented FC port use.
Selection Guide
1. Choose N9K-C9336C-FX2 for QSFP28-heavy designs
Select N9K-C9336C-FX2 when the design needs 36 40/100G QSFP28 ports in a 1RU Nexus 9300-FX2 switch and does not require Fibre Channel operation.
2. Choose N9K-C9336C-FX2-E only for the FC variant
Use N9K-C9336C-FX2-E when the official BOM requires 16/32G Fibre Channel support on the 9336C-FX2 hardware family. Do not treat the non-`-E` PID as the FC-capable replacement.
3. Compare against N9K-C93360YC-FX2 for dense SFP28 access
Move to N9K-C93360YC-FX2 only when the design needs 96 1/10/25G SFP28 access ports plus 12 40/100G QSFP28 ports instead of a uniform 36-port QSFP28 layout.
4. Verify software, airflow, and optics together
Confirm NX-OS or ACI image requirements, port-side intake or exhaust airflow, matching PSU and fan direction, and Cisco-supported optics, QSA adapters, or breakout cables before adding this SKU to the quote.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Port speed plan |
40G or 100G native ports, breakout use, and QSA adapter locations |
Prevents a port map that exceeds Cisco-documented adapter limits |
|
1G QSA placement |
1G QSA links only on ports 7-32 |
Keeps low-speed exceptions inside the supported port range |
|
Airflow direction |
Port-side intake or port-side exhaust across fans and power supplies |
Mixed airflow can create a cooling fault in the rack |
|
Power supply type |
750W AC, 1100W AC, 1100W DC, or 1100W HVAC/HVDC |
AC, DC, and high-voltage power choices affect site power design |
|
750W AC software baseline |
ACI-N9KDK9-14.2 or NXOS-9.3.3 and later for the 750W AC PSU |
Avoids ordering a PSU choice that is not supported by the planned image |
|
Software license package |
ACI or NX-OS Essential or Advantage package for a 10/25/40G+ Nexus 9K leaf |
Feature enablement depends on the selected Cisco licensing model |
|
Optics and cables |
Cisco-supported QSFP28 optics, DACs, AOCs, or QSA adapters |
The switch order and cabling BOM must match the validated transceiver list |
