N9K-C9364D-GX2A provides 64 fixed 400G QSFP-DD fabric ports in a 2U data center chassis, plus two fixed 1/10G SFP+ interfaces. The N9300-GX2 model supports NX-OS and ACI leaf or spine operation; base NX-OS capabilities cover Layer 2 switching and static routing, while separately selected licenses enable dynamic routing. Native 40G, 100G and 200G operation on the fabric interfaces accommodates lower-speed connections without changing the fixed-port architecture. Unlike N9K-C9348D-GX2A, which provides 48 fabric ports, this configuration supplies greater physical port density. Copper connectivity is reserved for management rather than RJ-45 access switching, and the optical data interfaces do not deliver PoE. The fixed chassis serves fabric purchases requiring a dense spine configuration rather than removable uplink cards or copper endpoint access.
N9K-C9364D-GX2A price for new stock is $201,033.33, a 50% saving from the Cisco list price of $402,066.66. N9K-C9364D-GX2A refurb price is $52,710.00. N9K-C9364D-GX2A is in stock and available for next-day dispatch. (terms applied)

51200 Gbps switching capacity establishes aggregate fabric bandwidth across the fixed interfaces. 8350 Mpps forwarding defines a separate packet-processing ceiling. 3124W maximum draw determines peak electrical provisioning rather than the output rating of NXA-PAC-3200W-PI. N9K-C9364D-GX2A carries 32 GB of DRAM and a 128 GB SSD for software and local storage; its 120 MB packet buffer is separate from both. PFC and ECN provide flow control and congestion signaling for compatible Ethernet fabrics. Static routing and HSRP operate under base NX-OS capabilities in the N9000 family; DCN Essentials enables BGP, OSPF, IS-IS, EIGRP and RIPv2. Hardware maxima reach 500000 MAC entries and 1000000 IPv4 LPM routes, independently of the selected routing entitlement. MACsec hardware covers only the first 16 fabric ports. Four NXA-SFAN-160CFM-2PI fan modules use 3+1 redundancy and port-side intake cooling, with the data interfaces facing the cold aisle.
ORM Systems offers N9K-C9364D-GX2A new sealed and certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, PSU and fan status, firmware verification, and a configuration wipe to factory default. Specify the required condition and complete hardware configuration on the purchase order before placing the order. Cisco's limited hardware warranty is 1 year; ORM coverage is up to 3 years extended for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply. PO acceptance, Net-30 for government and RMA with advance replacement support enterprise and volume purchasing.

N9K-C9364D-GX2A sits in the spine layer of a Nexus 9000 fabric and terminates high-density 400G links from leaf or aggregation switches on 64 QSFP-DD ports. Engineers map uplink groups across the 2RU chassis, reserve the two 1/10G SFP+ ports for operational connectivity, and align optics with Cisco compatibility guidance. NX-OS VXLAN EVPN or ACI mode defines the fabric control plane, licensing scope, and routing policy. The result is a dense 400G spine tier with fewer chassis positions and clear fabric-scale uplink planning.
The switch operates as a high-capacity leaf when a data center transitions server-facing connectivity from 100G toward 400G. N9K-C9364D-GX2A uses QSFP-DD ports for 400G hosts or downstream breakout groups, while native 100G QSFP28 support preserves links to existing adapters and fabric peers. Engineers stage port speeds, breakout maps, and VLAN or routed interfaces around the refresh sequence, then validate optics against the Cisco compatibility matrix. The network gains a controlled migration point that carries old and new server attachment speeds in the same fabric role.
N9K-C9364D-GX2A occupies a fabric handoff where selected high-value inter-switch links require physical-layer protection. Engineers place MACsec-enabled connections on the first 16 QSFP-DD ports, keep remaining 400G ports for unencrypted fabric capacity, and operate the switch under NX-OS or ACI according to the fabric standard. The two management interfaces support out-of-band administration during deployment, monitoring, maintenance windows, and software recovery work. Port selection keeps protected links explicit in fabric documentation. The result is an encryption boundary for critical leaf-to-spine paths without reducing the 64-port 400G fabric plan.
When a fabric migration must retain lower-speed connections, each QSFP-DD interface supports 4 x 10G, 4 x 25G, 4 x 50G, 4 x 100G or 2 x 200G breakouts. Map the required breakout profile and endpoint speeds before specifying the cable and optical configuration on the PO.
When sparing a fleet powered from DC sources, NXA-PDC-3200W-PI is the supported DC/HVDC choice. Power supply types cannot be mixed within one chassis. Record each installed source type and airflow direction before assigning spare inventory, then specify matching modules and quantities on the PO.
When staging out-of-band connectivity, the copper and optical management connectors are alternatives rather than simultaneously usable interfaces. Only one management port can be active. Establish whether the staging network requires copper or 1G fiber, reserve the console connection for initial setup, and specify the selected management connection before ordering.
MACsec across every fabric port
MACsec is restricted to the first 16 fabric ports. N9K-C9348D-GX2A supports encryption across all 48 fabric ports, but reduces physical port density from 64 to 48.
Port-side exhaust airflow
Port-side intake is the airflow direction for this model. N9K-C9332D-GX2B supports port-side exhaust, but changes the configuration to 32 fabric ports and a 1U chassis.
Powered copper endpoint connections
The fabric interfaces use optical cages rather than RJ-45 access ports. N9K-C9364D-GX2A does not supply PoE to phones, cameras or wireless access points.
Dynamic routing without software licensing
Base software provides static routing rather than BGP or OSPF entitlement. Dynamic routing requires an appropriate DCN subscription or an Advantage perpetual license such as NXOS-AD-XF2.

N9K-C9364D-GX2A identifies the 64-port 400/100G QSFP-DD model with two 1/10G SFP+ ports. N9K belongs to the Nexus 9000 family, C9364D is the model identifier, and GX2A identifies its generation. The part number does not select an Essentials, Advantage or Premier software tier.
N9K-C9364D-GX2A supports console-based setup, an IP-addressed CLI through one out-of-band management connection, Cisco Nexus Dashboard services, REST API, RESTCONF, NETCONF and gNMI. NX-OS and ACI are alternative operating modes. Management service availability depends on the selected software license; the copper and optical management ports are not used simultaneously.
N9K-C9364D-GX2A supports native 40G, 100G, 200G and 400G operation on its QSFP-DD fabric interfaces. Each interface also supports 4 x 10G, 4 x 25G, 4 x 50G, 4 x 100G or 2 x 200G breakouts. Compatible pluggables and the applicable software release determine the usable connection configuration.
N9K-C9364D-GX2A supports DCN Essentials, DCN Advantage and DCN Premier subscriptions for 3, 5 or 7 years, plus nonportable Advantage perpetual licensing. ACI-AD-XF2 covers ACI/NX-OS; NXOS-AD-XF2 covers NX-OS. Licensing uses Cisco Smart Accounts. The license path and term are separate selections from hardware condition, including certified refurbished purchases.
N9K-C9364D-GX2A includes static routes, SVIs and HSRP without an additional feature license. BGP, OSPF, IS-IS, EIGRP and RIPv2 require the appropriate routing entitlement. DCN Essentials supplies those routing features; Advantage includes Essentials features and adds higher-tier fabric functions. Hardware route-table capacity is separate from software entitlement.
No, N9K-C9364D-GX2A supports wire-rate MACsec on the first 16 fabric ports, not all 64. MACsec also requires a security add-on license. Under the NX-OS perpetual path, ACI-SEC-XF provides that entitlement; a base routing tier alone does not grant the separate security feature license.
N9K-C9364D-GX2A supports two power supply modules in a 1+1 arrangement. NXA-PAC-3200W-PI is the AC/HVDC option, and NXA-PDC-3200W-PI is the DC/HVDC option. Both installed modules must use the same power-source type; AC and DC supplies cannot form a mixed redundant pair within the chassis.
N9K-C9364D-GX2A provides 51200 Gbps switching capacity and an 8350 Mpps forwarding rate. These are separate bandwidth and packet-processing limits rather than interchangeable figures. The chassis also carries 120 MB of packet buffering, so memory planning should distinguish buffers from system DRAM and local SSD storage.
Cisco N9364D-GX2A occupies 2U in a standard equipment rack. The chassis measures 87.6 mm high, 442.3 mm wide and 757.6 mm deep. Port-side intake requires the optical interfaces to face the cold aisle. Cabinet depth, cabling clearance and airflow orientation need confirmation before the mounting configuration is specified.
N9K-C9364D-GX2A provides 64 fixed 400G fabric ports, while N9K-C9348D-GX2A provides 48. Both configurations retain two fixed 1/10G SFP+ interfaces. The former suits a purchase requiring higher physical fabric density; the latter suits a smaller port requirement within the GX2A generation without changing to a different interface speed class.
N9K-C9364D-GX2A uses a 3200W AC power configuration, whereas N9K-C9332D-GX2B uses a 1500W AC configuration. NXA-PAC-3200W-PI serves the former; NXA-PAC-1500W-PI or NXA-PAC-1500W-PE serves the latter. Buyers maintaining GX2A power inventory need the higher-rated configuration, while GX2B purchases use their corresponding lower-rated supply options.
N9K-C9364D-GX2A has 32 GB of system memory, while N9K-C9332D-GX2B-M has 64 GB. The larger memory allocation belongs to the -M hardware configuration rather than the selected subscription tier. The former fits a purchase specified around 32 GB; the latter addresses a requirement for the 64 GB memory configuration.
N9300-GX2 switches can continue operating with base license capabilities after an expired add-on license is deactivated and the switch is reloaded. Continued use of the add-on requires renewal. Subscription expiration does not convert the hardware purchase into an Advantage perpetual entitlement; those are separate licensing purchases.
Cisco has not announced an end-of-sale date for N9300-GX2. N9K-C9364D-GX2A has no announced hardware retirement milestones. Software planning still needs a compatible release and the required feature license; retirement of an individual software release does not itself retire this hardware part number.
N9K-C9364D-GX2A is offered new sealed with up to 3-year extended ORM coverage or certified refurbished with up to 1-year ORM coverage; Cisco's separate limited hardware warranty is 1 year. Returns cover every condition for 30 days, terms apply. Refurbished units are inspected and bench-tested.
