N9K-C9336PQ is a fixed Cisco ACI spine switch with 36 QSFP+ interfaces operating at 40 Gigabit Ethernet in a 2U rack-mount chassis. The Nexus 9300 ACI Fixed Spine family connects ACI leaf switches rather than providing copper endpoint access or PoE. APIC, spine switches, and leaf switches form the fabric, so the hardware order must fit the existing controller-based architecture. The discontinued N9K-C9336PQ= spare configuration excludes power supplies, fans, and the accessory kit; chassis contents therefore distinguish otherwise similar quotes. The Cisco N9336PQ ACI Spine Switch is a like-for-like procurement option for an existing fabric retaining its original interconnect architecture. Treat the fabric software release and the required hardware assembly as separate checks before selecting stock.
N9K-C9336PQ price for new stock is $1,711.50, a 95.9% saving from the Cisco list price of $41,400.00. N9K-C9336PQ refurb price is $367.50. N9K-C9336PQ is in stock and available for next-day dispatch. (terms applied)

2880 Gbps switching capacity defines the chassis bandwidth available for fabric traffic. 2300 Mpps forwarding performance provides a separate packet-rate sizing check. N9K-C9336PQ carries 16 GB of system memory and 64 GB of SSD storage, separating working memory from local software storage. A dedicated 10/100/1000BASE-T management connection and an RS-232 serial console provide physical management access without consuming fabric interfaces; two USB ports provide additional local connectivity. The Nexus 9000 Series chassis accepts AC, DC, or HVAC/HVDC power configurations, which must match the installed power components and site feed. 660W maximum AC consumption is the figure to reserve for rack power planning, rather than a power supply's output rating; 400W typical AC consumption is a different operating reference. An operating range of 0°C to 40°C sets the ambient-temperature boundary for installation. Two fan trays with redundant fans provide forced-air cooling, so airflow orientation remains part of the assembly specification.
ORM Systems offers N9K-C9336PQ new sealed or certified refurbished; refurbished units are inspected and bench-tested, including optics bay recognition, with firmware verified and configurations wiped to factory default. Specify condition, power components, and required accessories on the purchase order. ORM coverage is up to 3-year extended for new units or up to 1 year for certified refurbished units, with 30-day returns in every condition, terms apply; Cisco's original 1-year limited hardware warranty ended March 31, 2024. Enterprise and volume orders can use PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock and RMA in the UK, EU, US, and MEA.

In a global service-provider environment migrating hundreds of legacy racks to a unified ACI fabric, the N9K-C9336PQ-Nexus 9336 ACI Spine switch with 36p 40G QSFP delivers 1.44 Tbps of non-blocking bandwidth for over 200 leafs. This high-density spine reduces east-west latency to sub-microsecond levels, boosts VM-provisioning speed by 50%, and enforces micro-segmentation consistently, driving a 35% drop in operational costs.
For an enterprise data lab running GPU-accelerated AI/ML workloads, deploying the N9K-C9336PQ-Nexus 9336 ACI Spine switch with 36p 40G QSFP ensures a lossless, low-latency 40 GbE fabric connecting 64 GPU servers. This configuration delivers full-hour throughput at 1.44 Tbps, slashes inter-node latency by 60%, and accelerates model training cycles by up to 3×, enabling faster time-to-insight and higher research productivity.
In a multi-building corporate campus consolidating branch offices and data closets, the N9K-C9336PQ-Nexus 9336 ACI Spine switch with 36p 40G QSFP acts as a central core switch for 40 GbE uplinks. It simplifies network operations through policy-driven automation, increases aggregate throughput by 2.5×, and reduces rack-to-rack latency by 70%, resulting in consistent application SLAs and a 40% reduction in network maintenance overhead.
Across data centers with different electrical and airflow arrangements, identify the required assembly before standardizing the order. N9K-PAC-1200W provides port-side intake airflow, while N9K-PAC-1200W-B provides port-side exhaust airflow. Specify the supply PID and regional power-cord configuration for each site rather than treating every chassis quote as equivalent.
For staging in a shared test room, acoustic output needs planning before the chassis arrives. Fan operation reaches 89.8 dBA at full speed, compared with 64.4 dBA at 40% fan speed. Specify a suitable test location and verify the available airflow path before adding the unit to the PO.
100G leaf-to-spine fabric connections
N9K-C9336PQ fabric interfaces operate at 40GbE, not 100GbE. N9K-C93600CD-GX provides 28 x 100G ports plus 8 x 400G ports for a higher-speed migration.
More than 36 fabric connections
N9K-C9336PQ has 36 fixed fabric interfaces without a port-expansion bay. N9K-C9364C-GX provides 64 x 40/100G interfaces when the order requires greater fabric-port density.
Active Cisco hardware service coverage
Cisco service for N9K-C9336PQ ended March 31, 2024. Select a current migration target, N9K-C9364C-GX or N9K-C93600CD-GX, instead of planning a new Cisco support contract.
ACI switch software 15.0(1) or later
N9K-C9336PQ is unsupported on ACI switch software 15.0(1) or later. A fabric moving into that release range requires replacement of this spine before the upgrade.

N9K-C9336PQ identifies a Nexus 9000 ACI spine switch with 36 fixed 40 Gigabit Ethernet QSFP+ ports. N9K identifies the Nexus 9000 family, while C9336PQ identifies this chassis configuration. Compare complete ordering identifiers carefully: a spare configuration can exclude operating components without changing the underlying fabric-port configuration.
The Cisco N9336PQ ACI Spine Switch is managed within an ACI fabric through the Application Policy Infrastructure Controller, or APIC. The fabric combines APIC, spine switches, and leaf switches for centralized policy and automation. A serial console and dedicated copper management connection provide physical access for local operations.
Yes, N9K-C9336PQ is discontinued: end of sale was March 5, 2019, and Cisco service ended March 31, 2024. N9K-C9332C and N9K-C9364C were original migration targets; both are discontinued, with current migration paths ending at N9K-C93600CD-GX and N9K-C9364C-GX. Remaining stock does not restore Cisco service eligibility.
ORM Systems offers N9K-C9336PQ new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are 30 days in every condition; terms apply. Cisco's original warranty was 1-year limited hardware coverage, and Cisco service ended March 31, 2024.
N9K-C9336PQ has 36 fixed QSFP+ fabric interfaces operating at 40 Gigabit Ethernet. The interfaces are built into the chassis rather than supplied by a removable uplink card, and the switch occupies 2U. Specify compatible leaf-to-spine connections without treating the dedicated management connection as an additional fabric interface.
N9K-C9336PQ accepts 1200W AC N9K-PAC-1200W or N9K-PAC-1200W-B, 1200W HVAC/HVDC N9K-PUV-1200W, and 930W DC UCSC-PSU-930WDC or UCS-PSU-6332-DC. Match the assembly's airflow direction and site input power before ordering. Specify the supply quantity and exact supply PID on the quote rather than relying on a generic power description.
N9K-C9336PQ has 660W maximum AC consumption and 400W typical AC consumption. Use maximum draw, not power supply output capacity, when allocating circuit capacity and rack power. Confirm the input voltage and selected electrical configuration separately because the chassis also accepts DC and HVAC/HVDC power supply options.
N9K-C9336PQ provides 2880 Gbps switching capacity and 2300 Mpps packet-forwarding performance. These are separate chassis performance measures, not power supply ratings or memory capacities. Use bandwidth and packet rate as independent checks when sizing fabric traffic and deciding whether replacement stock matches the requirements of an existing installation.
N9K-C9336PQ= is a discontinued spare chassis without an accessory kit, power supplies, or fans; N9K-C9336PQ is the main switch identifier. Both products are discontinued and Cisco service has ended. A spare chassis suits component reuse, while an assembled unit suits an order that must include operating hardware.
N9K-C93600CD-GX provides 28 x 100G ports and 8 x 400G ports, whereas N9K-C9336PQ provides 36 x 40G ports. The current model ends the migration path through the discontinued N9K-C9332C. The original chassis suits like-for-like 40G sparing; the current model suits orders requiring faster fabric connections.
N9K-C9364C-GX provides 64 fabric ports where N9K-C9336PQ provides 36. The current 64-port model follows the discontinued N9K-C9364C in the migration chain. Existing installations needing an identical spare can retain the original port count; buyers requiring more fabric connections should specify the current higher-density model.
No, N9K-C9336PQ is not supported on ACI switch software 15.0(1) or later. Replace this spine with supported hardware before moving an existing fabric into that release range. An upgrade attempt on unsupported hardware reverts to the previously installed release, leaving fabric devices with inconsistent firmware releases.
