Technical Identity
The Cisco N9K-C9336C-FX2 is the Cisco Nexus 9336C-FX2, a Nexus 9300-FX2 series 1RU data center switch built on Cisco Cloud Scale technology, with 36 QSFP28 ports supporting 40/100 Gigabit Ethernet and up to 7.2 Tbps of bandwidth. Ports can be configured for 1/10/25/40/50/100G operation and breakout is supported on all ports. The platform runs in either Cisco NX-OS standalone mode or Cisco ACI fabric mode and supports VXLAN EVPN designs. Condition: Refurbished. Quantity available: 2 units.

Engineering Context
The Nexus 9336C-FX2 is one of the most widely deployed 100G fixed switches of its generation and was Cisco's designated migration platform for the earlier Nexus 9236C and 9300-EX 100G models. Its Cloud Scale ASIC provides larger buffers and telemetry capabilities, and its dual-personality software support (NX-OS or ACI) makes the same hardware usable as a standalone VXLAN EVPN leaf/spine node or as an ACI spine/leaf. All-port breakout allows dense 4x25G or 4x10G fan-out from a single rack unit.
Use Cases

100G leaf or spine in NX-OS VXLAN EVPN fabrics
ACI spine or leaf node in Cisco ACI data centers
High-density 25G access via 4x25G breakout on any port
Data center interconnect and storage backbones at 40/100G

What This Is NOT

NOT a 400G platform. Ports are QSFP28 100G — QSFP-DD 400G optics will not operate here.
NOT the Nexus 9336C-FX2-E. The -E is a newer enhanced PID; this listing is the standard N9K-C9336C-FX2.
NOT the Nexus 9336PQ. That is an older 40G-only ACI spine with a different PID.
NOT a Nexus 9200. Unlike the 9200 platform, this 9300-FX2 switch supports both NX-OS and ACI modes.
NOT a modular chassis. Fixed 36-port configuration with no line-card slots.
NOT supplied with optics, cables, rail kits, software licenses, or support entitlements unless explicitly stated.

Compatibility & Hard Constraints

Optics/cabling: QSFP28 100G and QSFP+ 40G transceivers, DAC/AOC, and 4x25G / 4x10G breakout assemblies per Cisco's optics-to-device compatibility matrix.
Software: supported NX-OS or ACI releases per Cisco documentation for the 9336C-FX2; feature availability depends on release and licensing.
Mode choice: NX-OS standalone and ACI mode require different software images and conversion procedures — plan the target mode before deployment.
Airflow/power: confirm port-side intake vs. exhaust of installed fan/PSU modules matches your aisle design.
Pre-deployment verification: confirm software image, license level, optics support, and breakout configuration before production use.

Frequently Asked Questions (FAQ)
Q. What is the Cisco N9K-C9336C-FX2?
It is the Cisco Nexus 9336C-FX2: a 1RU Cloud Scale data center switch with 36x QSFP28 40/100GbE ports, up to 7.2 Tbps of bandwidth, and support for both NX-OS standalone and ACI fabric modes.
Q. Does the N9K-C9336C-FX2 support breakout on all ports?
Yes. All 36 QSFP28 ports support breakout (for example 4x25G or 4x10G), subject to the software release configuration guidelines.
Q. Can the N9K-C9336C-FX2 run Cisco ACI?
Yes. As a Nexus 9300-FX2 platform it can operate in ACI fabric mode or NX-OS standalone mode; the two modes use different software images.
Q. Is this the same as the Nexus 9336C-FX2-E?
No. The N9K-C9336C-FX2-E is a separate enhanced PID. This listing is the standard N9K-C9336C-FX2.
Q. Does it support 400G optics?
No. The cages are QSFP28 — 100G maximum per port. 400G requires a QSFP-DD platform.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. Each unit is inspected and tested where test topology is available, cleaned, and shipped in professional protective packaging from EU stock. Two units are available.
Why T.E.S IT-SOLUTIONS
Every N9K-C9336C-FX2 unit ships with: (1) functional verification where test topology is available, (2) configuration wipe and inspection, (3) full cosmetic check, (4) professional protective packaging, (5) global B2B shipping from EU stock, (6) technical consultation for data center network design at no extra cost.
Condition: Refurbished. No optics, cables, rails, software licenses, or vendor support entitlements are included unless explicitly stated.
