Data Center Core and Aggregation Switching
N9K-C9504 is a four-slot modular chassis for data center core, aggregation and spine switching. Cisco N9504 network interfaces come from installed line cards rather than fixed access ports. The N9500 Series sibling N9K-C9508 accommodates eight line cards when a configuration requires greater module density.
N9K-C9504 price for new stock is $7,952.70, a 46.6% saving from the Cisco list price of $14,882.00. N9K-C9504 refurb price is $792.75. N9K-C9504 is in stock and available for next-day dispatch. (terms applied)

Technical Details
N9K-C9504 can operate in NX-OS or Cisco ACI mode. NX-API enables automation, while DCNM manages NX-OS deployments. Redundant supervisors must be the same type, and installed fabric modules must match. Interface speeds, forwarding performance and power consumption depend on the completed hardware configuration rather than the chassis PID alone.
Ordering
N9K-C9504 is offered new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on, POST, clean boot and module bay recognition, with managed units firmware verified and wiped to factory default. ORM warranty coverage is up to three years extended for new units and up to one year for certified refurbished units, with 30-day returns on every condition, terms apply. Specify the condition, quantity and complete component requirements on the purchase order rather than treating the chassis as a complete switch. Enterprise and volume orders can use purchase orders, government Net-30 terms and RMA with advance replacement.

N9K-C9504 Use Case
Data Center Core Aggregation
N9K-C9504 sits in the data center core as a 7 RU Nexus 9500 chassis populated with selected supervisors, fabric modules, power supplies, and up to four line cards. Engineers terminate high-speed leaf, distribution, or service-block links on the installed Nexus 9500 modules, then run NX-OS routing, switching, and telemetry features according to the chosen software release. Redundant supervisors and fabric modules keep the control plane and internal forwarding path modular. The network gains a compact chassis-based core with defined growth inside four line-card slots.
ACI Spine Fabric Position
The Nexus 9504 operates as an ACI spine chassis when the bill of materials uses ACI-supported supervisors, fabric modules, and cloud-scale line cards such as Nexus 9500 100G or 400G options. N9K-C9504 connects leaf switches through the installed line cards while rear fabric modules distribute traffic across the chassis backplane. Engineers validate each line card against Cisco ACI release support before activation. The fabric gains a four-slot spine position that keeps modular expansion, power redundancy, and fabric selection under one chassis design.
End-of-Row Server Access Expansion
N9K-C9504 occupies an end-of-row position when server racks aggregate into Nexus 9500 line cards rather than individual fixed switches. Engineers select copper, SFP, QSFP28, or QSFP-DD line cards to match server NIC speeds and upstream aggregation requirements, then reserve remaining slots for planned migration from lower-speed to higher-speed links. The 4-slot chassis keeps supervisors, fabric modules, fans, and power supplies serviceable as field-replaceable units during maintenance windows. The access layer gains modular port migration without replacing the entire switching platform.
Best For
Fabric Mode Transition
When an existing configuration is moving between operating modes, ACI-mode and NX-OS-mode line cards cannot be mixed in the same switch. Keep the intended mode consistent across the hardware list and check every retained line card against the replacement configuration before releasing the purchase order.
Regional Chassis Sparing
When a spare chassis must cover an installed estate across regions, specify the replacement condition and receiving location before purchasing. ORM Systems provides regional stock and RMA coverage across the UK, EU, US and MEA; identify the relevant location and required quantity on the purchase order.
Not Suitable If
More than four line cards
N9K-C9504 accommodates four line cards. N9K-C9508 accommodates eight, but requires 13 rack units rather than seven; include the larger chassis footprint in the rack plan.
Standalone operation without additional components
N9K-C9504 is a modular chassis, not a self-contained fixed-port switch. Network connectivity and switching operation require a compatible installed component configuration.

Questions & Answers
What does the N9K-C9504 part number mean?
N9K-C9504 identifies the Cisco N9504 chassis with four line-card slots. The complete PID selects a modular chassis, not four Ethernet ports or a particular software license tier.
How is N9K-C9504 managed?
N9K-C9504 supports CLI management through the supervisor console and out-of-band Ethernet interface, NX-API automation and DCNM management in NX-OS mode. Cisco ACI deployments use APIC. Management connections and software selection belong in the complete system configuration.
Is N9K-C9504 end of sale?
Cisco has not announced an end-of-sale date for N9K-C9504. The N9500 family has separate retirement notices for selected chassis and components. Component milestones are not automatically a retirement date for this four-slot chassis; check the lifecycle of each installed component before retaining an existing configuration.
Which conditions and warranties does ORM Systems offer for N9K-C9504?
New sealed and certified refurbished N9K-C9504 units are offered. Cisco provides a one-year limited hardware warranty. ORM provides up to three years extended coverage for new units and up to one year for certified refurbished units. Every condition includes 30-day returns, terms apply. Refurbished units are inspected and bench-tested, including module bay recognition.
Which licensing paths are available for N9K-C9504?
N9K-C9504 ACI licensing offers DCN Essentials, DCN Advantage and DCN Premier subscriptions with three-, five- or seven-year terms. Perpetual DCN Advantage is available as ACI-AD-M4. Subscription licenses cover ACI and NX-OS features; perpetual licenses are not portable between devices.
Does the Cisco N9504 have fixed Ethernet ports?
The Cisco N9504 chassis has no fixed Ethernet access ports. Its four line-card slots provide network interfaces through the selected cards, so port count and interface speed must be specified separately.
Can N9K-C9504 support 400G interfaces?
N9K-C9504 supports the N9K-X9716D-GX line card with sixteen 400G interfaces. That card works with N9K-C9504-FM-G fabric modules, which require N9K-C9504-FAN2 cooling. These are configuration components, not fixed ports included in the chassis PID.
Which power supplies can the Cisco N9504 use?
The Cisco N9504 accepts N9K-PAC-3000W-B AC, N9K-PDC-3000W-B DC, N9K-PUV-3000W-B universal AC/DC and N9K-PUV2-3000W-B dual-input universal AC/DC supplies. Supply quantity and redundancy mode depend on the installed component load; supply output ratings are not chassis power-consumption figures.
What is the difference between N9K-C9504 and N9K-C9508?
N9K-C9504 has four line-card slots, whereas N9K-C9508 has eight. N9K-C9504 suits configurations that fit within four cards; N9K-C9508 is the same-family option when the required component configuration exceeds that slot count.
Does N9K-C9504 ACI Smart Licensing require a Smart Account?
N9K-C9504 ACI Smart Licensing requires a Smart Account in Cisco License Central. Identify the account administrator before placing the licensing order. Account handling is separate from the chassis hardware configuration, and an existing nontransferable perpetual license cannot simply move to another device.
