Cisco N3K-C3132Q-40GX — Nexus 3132Q-X 32-Port QSFP+ 40G Data Center Switch, 1RU
Technical Identity
The Cisco N3K-C3132Q-40GX is the Cisco Nexus 3132Q-X, a 1RU Layer 2/Layer 3 data center switch with 32 QSFP+ 40 Gigabit Ethernet ports plus 4 SFP+ ports (the SFP+ ports are internally multiplexed with the first QSFP+ port). It runs Cisco NX-OS and delivers up to 2.5 Tbps of Layer 2/3 switching capacity. The 3132Q-X is a hardware revision of the Nexus 3132Q with a revised port layout and an LED lane selector. Cisco's last day to order this model was April 27, 2020 (end-of-sale). Condition: Refurbished. Note on stock labels: our units carry either the PID label N3K-C3132Q-40GX or the chassis marking NEXUS3132Q-X — both refer to the same switch model; this listing covers both label variants.

Engineering Context
The Nexus 3132Q-X was built for dense 40G aggregation and leaf/spine roles in 10/40G data center fabrics. With 32 line-rate QSFP+ ports in one rack unit, it is typically deployed as a 40G spine above 10G top-of-rack switches, or as a breakout-heavy 10G access layer using 4x10G splitter cabling. As a Nexus 3100-series platform it runs standard NX-OS (not ACI), which keeps configuration familiar for teams operating Catalyst/Nexus environments.
Use Cases

40G spine or aggregation layer for 10G ToR fabrics
High-density 10G server access via 4x10G QSFP+ breakout cabling
Lab, staging, and test environments that need line-rate 40G at refurbished cost
Cost-controlled capacity expansion of existing Nexus 3100 estates

What This Is NOT

NOT a 100G switch. Ports are QSFP+ 40G — QSFP28 100G operation is not supported.
NOT the Nexus 3132Q-V or 3132Q-XL. Those are different PIDs (N3K-C3132Q-V / N3K-C3132Q-XL) with different hardware.
NOT a QSFP-DD / OSFP platform. QSFP-DD and OSFP optics will not fit these cages.
NOT an ACI-capable Nexus 9000. This is a Nexus 3100 running standalone NX-OS only.
NOT a currently orderable Cisco product. End-of-sale since April 2020; plan support accordingly.
NOT supplied with optics, cables, rail kits, or software support entitlements unless explicitly stated.

Compatibility & Hard Constraints

Optics/cabling: QSFP+ 40G transceivers, 40G DAC/AOC, and 4x10G breakout assemblies per Cisco's optics compatibility matrix; SFP+ 1/10G on the four multiplexed ports.
SFP+ port constraint: the 4 SFP+ ports share capacity with QSFP+ port 1 — both cannot run independently at the same time.
Software: supported NX-OS releases per Cisco documentation for the Nexus 3132Q-X; verify feature licensing requirements for your target release.
Airflow/power: confirm port-side intake vs. exhaust of the installed fan/PSU modules matches your hot/cold aisle design.
Pre-deployment verification: confirm NX-OS version, optics support, and breakout configuration before production use.

Frequently Asked Questions (FAQ)
Q. What is the Cisco N3K-C3132Q-40GX?
It is the Cisco Nexus 3132Q-X: a 1RU NX-OS data center switch with 32x QSFP+ 40GbE ports plus 4x SFP+ ports, delivering up to 2.5 Tbps of Layer 2/3 switching.
Q. Does the N3K-C3132Q-40GX support 100G QSFP28 optics?
No. The ports are QSFP+ 40G. For 100G you need a QSFP28 platform such as the Nexus 9236C or 9336C-FX2.
Q. What are the 4 SFP+ ports for?
They are 1/10G SFP+ ports internally multiplexed with the first QSFP+ port — useful for 10G uplinks or management-adjacent connectivity, but they share capacity with QSFP+ port 1.
Q. Can each QSFP+ port break out to 4x 10G?
Yes. Each of the 32 QSFP+ ports can run native 40G or 4x10G mode, for up to 104 usable 10G ports on the N3K-C3132Q-40GX.
Q. Why are some units labeled NEXUS3132Q-X instead of N3K-C3132Q-40GX?
Cisco prints both the marketing model (Nexus 3132Q-X) and the orderable PID (N3K-C3132Q-40GX) on different labels. Both markings identify the same switch; this listing merges both label variants.
Q. What is the lifecycle status?
Cisco's last day to order the Nexus 3132Q-X was April 27, 2020. Verify remaining support milestones against Cisco's EoL bulletin; refurbished units are typically run under self-maintenance or third-party support.
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.
Why T.E.S IT-SOLUTIONS
