N9K-C9504 is a managed Layer 3 modular data center switch chassis with no fixed network ports; its port count and Ethernet speeds come from installed Cisco Nexus 9500 line cards. The chassis accepts modular line-card options for BaseT, SFP+, SFP28, QSFP, QSFP28, and QSFP-DD connectivity, so uplink and downlink roles are defined by separately ordered modules rather than fixed front-panel ports. PoE is not provided by the chassis platform, which keeps power planning focused on supervisors, fabric modules, fan trays, power supplies, and selected network modules. The chassis form factor belongs to the Cisco Nexus 9500 Series, a modular data center family used for spine, core, aggregation, gateway, and end-of-row switching. N9K-C9508 is the closest larger sibling, and its documented difference is 8 line-card slots instead of the 4 slots in N9K-C9504.
51.2 Tbps nonblocking performance supports high-density Nexus 9500 fabrics when the chassis is populated with suitable fabric modules and line cards. 38092.8 Mpps derived forwarding rate follows the standard 64-byte line-rate calculation from the documented switching capacity. Layer 3 operation runs through Cisco NX-OS or Cisco ACI deployments, with NX-OS support for VXLAN with BGP-EVPN, segment routing, MPLS, and open APIs when the installed hardware and software release support those features. N9K-C9504 supports up to 2 supervisors of the same type, up to 2 system controllers, up to 6 fabric modules of the same type, up to 3 fan trays, and up to 4 power supplies. The internal Clos design connects line cards directly to rear fabric modules, and traffic load-balances across installed fabrics so a fabric-module loss reduces capacity while the remaining modules continue forwarding. Hot-swappable AC, DC, and universal AC/DC power supply options support combined, n+1, and n+n redundancy modes for chassis power planning.
Data center core, aggregation, spine, gateway, and end-of-row server access deployments use the platform when a modular Nexus 9500 footprint fits the interface plan. Server NICs, leaf switches, service appliances, and upstream fabric links connect through the selected line cards, while rack planning reserves 7U of cabinet space plus service clearance for the 842 mm chassis depth. Stacking is not a Nexus 9504 chassis function; scale is handled through modular line-card selection, fabric capacity, and network topology design. N9K-C9504 is available from ORM Systems in new and certified refurbished condition, with refurbished chassis checks focused on power bays, fan trays, supervisor recognition, fabric-module slots, and line-card slot readiness. Send the required chassis build to ORM Systems for a formal quote; enterprise and volume buyers receive configured pricing for deployment builds, expansion projects, spare-unit coverage, multi-site standards, and critical spare pools.
N9K-C9504 price is $7,574.00, a 49.1% saving from the Cisco list price of $14,882.00. N9K-C9504 is in stock and available for next-day dispatch. (terms applied)

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.
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.
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.

The Cisco N9K-C9504 is a Nexus 9504 modular data center switch chassis in the Cisco Nexus 9500 Series. It is a 4-slot chassis designed for high-density switching roles where line cards, fabric modules, supervisors, system controllers, fan trays, and power supplies are selected to match the required network design.
N9K-C9504 identifies a Cisco Nexus 9000 Series modular chassis, with C9504 indicating the Nexus 9504 4-slot chassis form factor. The SKU refers to the chassis platform itself, not a fixed-port switch, so final interface count and speed depend on the installed Nexus 9500 line cards and fabric modules.
N9K-C9504 is a modular switch chassis, not a standalone fixed-port switch or a line card. It provides the physical Nexus 9504 frame for up to 4 line cards, up to 6 fabric modules, redundant supervisors, system controllers, fan trays, and power supplies. Ports are provided by separately selected line cards.
The Cisco Nexus 9504 sits in the Nexus 9500 modular chassis family as the smallest chassis option. It is positioned below the N9K-C9508 8-slot chassis and N9K-C9516 16-slot chassis, giving data center teams a modular Nexus 9000 platform when four line-card slots are enough for the planned design.
N9K-C9504 supports up to 4 line cards in the Nexus 9504 chassis. Cisco also lists support for up to 4 power supplies, up to 6 fabric modules of the same type, up to 2 system controllers, up to 2 supervisors of the same type, and up to 3 fan trays in the same chassis.
Switching capacity for N9K-C9504 depends on the installed fabric modules and line cards. Cisco cloud-scale Nexus 9500 line cards provide up to 6.4 Tbps per slot, while 4-slot FM-G fabric modules provide up to 1.6 Tbps capacity per line card slot. The chassis design uses rear-mounted fabric modules for load-balanced line-card interconnect.
N9K-C9504 uses field-replaceable, hot-swappable power and cooling components sized to the chosen line-card and fabric-module mix. The 4-slot chassis supports up to 4 power supplies and up to 3 fan trays. Cisco lists front-panel-accessible AC, DC, and universal high-voltage AC/DC power supply options for the Nexus 9500 platform.
N9K-C9504 is a 7 RU chassis with Cisco-listed dimensions of 12.25 x 17.50 x 33.15 inches, or 31.1 x 44.5 x 84.2 cm. The chassis weight is listed at 84 lb, or 38.2 kg, before the final installed mix of supervisors, line cards, fabric modules, fans, and power supplies.
N9K-C9504 supports redundant supervisor modules and redundant system controllers as part of the Nexus 9500 architecture. Cisco describes supervisors as an active-standby pair for switch operations, while system controllers manage chassis functions including power supplies, fan trays, and the internal Gigabit Ethernet out-of-band channel between modules.
N9K-C9504 belongs to the Cisco Nexus 9500 platform, which supports Cisco ACI and Cisco NX-OS deployments when populated with compatible supervisors, fabric modules, line cards, and software releases. Cisco notes that hardware capability and software feature support should be checked against the relevant ACI or NX-OS release documentation.
N9K-C9504 is used as a modular data center switching chassis for core, aggregation, gateway, spine, or end-of-row access designs. The 4-slot form factor fits networks that need Nexus 9500 modularity without the larger physical footprint of the 8-slot or 16-slot chassis. Installed modules determine final port speed and density.
N9K-C9504 suits core and aggregation roles when the required port density fits four line-card slots. Network architects use Nexus 9500 fabric modules and high-speed line cards to aggregate leaf, distribution, or service blocks. The chassis provides modular supervisors, fabric capacity, and power redundancy for designs that need centralized high-speed switching.
N9K-C9504 fits end-of-row server access designs when rack or blade server connections aggregate into modular Nexus 9500 line cards. Cisco describes Nexus 9500 switches as suitable for high-density multispeed Ethernet and incremental migration from lower-speed to higher-speed server connections. The selected line cards define whether the deployment uses copper, SFP, QSFP, or QSFP-DD interfaces.
N9K-C9504 is appropriate for Cisco ACI spine roles when built with ACI-supported Nexus 9500 line cards, fabric modules, supervisors, and software. Cisco cloud-scale line-card tables list several Nexus 9500 modules for Cisco ACI spine and Cisco NX-OS use. Final suitability depends on the exact bill of materials and software release.
N9K-C9504 supports Cisco Nexus 9500 line-card families selected for the required interface speeds, port density, buffer profile, and software mode. Examples from Cisco cloud-scale documentation include N9K-X9716D-GX 400G QSFP-DD, N9K-X9736C-FX3 100G QSFP28, N9K-X97160YC-EX 1/10/25G SFP28 plus 40/100G QSFP28, and N9K-X9788TC-FX 1/10G BaseT plus 40/100G QSFP28.
N9K-C9504 uses Nexus 9500 4-slot fabric modules matched to the chosen line cards, throughput target, and fan trays. Cisco lists N9K-C9504-FM-G, N9K-C9504-FM-E, N9K-C9504-FM-R, N9K-C9504-FM-S, and N9K-C9504-FM options in Nexus 9500 documentation. All fabric modules installed in a modular switch should be of the same type.
N9K-C9504 integrates with the Nexus 9500 supervisor and system controller ecosystem used for modular chassis operation. Cisco lists supervisor options such as N9K-SUP-A, N9K-SUP-A+, N9K-SUP-B, and N9K-SUP-B+, with redundant supervisors of the same type recommended within a chassis. The N9K-SC-A system controller handles chassis management functions in the platform.
N9K-C9504 deployments operate inside Cisco Nexus 9000 data center ecosystems, including Cisco NX-OS and Cisco ACI when the hardware and software combination is supported. Cisco Nexus 9500 cloud-scale documentation references Layer 2 and Layer 3 networking, policy-based fabric architectures, VXLAN, smart buffering, line-rate security, and streaming telemetry across compatible modules.
N9K-C9504 is the smaller Nexus 9500 chassis with 4 line-card slots, while N9K-C9508 provides 8 line-card slots. N9K-C9504 is 7 RU and listed at 84 lb, compared with the 13 RU, 150 lb N9K-C9508. The 9504 fits smaller modular builds, while the 9508 fits higher port-density designs.
N9K-C9504 provides 4 line-card slots, while N9K-C9516 provides 16 line-card slots for much larger Nexus 9500 builds. Cisco lists the 9504 at 7 RU and 84 lb, compared with the 21 RU, 192 lb 9516. The N9K-C9504 is better aligned to constrained cabinets or smaller aggregation domains.
N9K-C9504 is the better fit when four line-card slots cover the planned port count and a 7 RU chassis is preferred. N9K-C9508 is the growth option when the design needs up to 8 line cards, up to 8 power supplies, and a larger chassis footprint. Both remain within the Nexus 9500 modular family.
N9K-C9504 is a Nexus 9500 7 RU modular chassis with 4 line-card slots, while N9K-C9408 is a newer Nexus 9400 4 RU chassis with 8 expansion slots for high-density 400G designs. N9K-C9408 is not a slot-for-slot replacement for Nexus 9500 line cards, fabric modules, supervisors, or operating procedures.
N9K-C9504 is typically sourced by ORM Systems in new or refurbished condition depending on channel availability, project timing, and required module bundle. Buyers should specify whether the requirement is for the bare chassis, a tested chassis with fans and power supplies, or a fuller configuration with supervisors, fabric modules, and line cards.
N9K-C9504 price depends on condition, lead time, warranty length, and the included components. A bare Nexus 9504 chassis prices differently from a configured system with supervisors, fabric modules, fan trays, power supplies, and line cards. ORM Systems can quote the SKU against the required bill of materials for accurate project pricing.
N9K-C9504 lifecycle status should be checked against Cisco notices and the exact configured components at quote time. Cisco publishes separate end-of-sale and end-of-life notices for some Nexus 9500 fabric modules, supervisors, software releases, and line cards. The lifecycle status of one module does not automatically define the chassis status.
N9K-C9504 lead time depends on whether the buyer needs the chassis only or a tested configuration with matching supervisors, system controllers, fans, power supplies, fabric modules, and line cards. Refurbished inventory may move faster when available, while new or specially configured Nexus 9504 systems may require additional sourcing and validation time.
Bulk pricing for N9K-C9504 is relevant when projects need multiple chassis, spare power supplies, fan trays, fabric modules, supervisors, or matching line cards. ORM Systems can price volume requirements as a complete Nexus 9504 bill of materials, which helps buyers compare chassis-only purchases with fully prepared deployment spares.
N9K-C9504 warranty options from ORM Systems depend on condition, availability, and the final configured components. ORM Systems commonly supports enterprise hardware sales with warranty coverage options up to 3 years where available. Buyers should confirm whether warranty coverage applies to the chassis only or to included modules, fans, and power supplies.
A refurbished N9K-C9504 should be tested as a chassis platform before dispatch, with attention to power-up behavior, fan tray operation, supervisor recognition, fabric-module slots, line-card slots, management access, and visible hardware condition. Testing is especially important because the final Nexus 9504 system depends on several field-replaceable modules working together.
Cisco lists Nexus 9504 chassis compliance information including CE marking, UL 60950-1, CAN/CSA-C22.2 No. 60950-1, EN 60950-1, IEC 60950-1, AS/NZS 60950-1, GB4943, Class A emissions standards, EMC immunity standards, and RoHS-6 compliance with stated exceptions. Buyers should confirm local regulatory documentation for the delivered configuration.
N9K-C9504 first-use configuration requires the correct physical build before software work begins. Network teams install compatible supervisors, system controllers, fabric modules, fan trays, power supplies, and line cards, then connect console or management Ethernet access. NX-OS or ACI mode planning should be completed before cabling production links into the selected line cards.
N9K-C9504 software and licence requirements depend on whether the deployment runs Cisco NX-OS or Cisco ACI and which features are enabled. The chassis hardware alone does not define the complete entitlement position. Buyers should align supervisors, line cards, software release, Smart Licensing requirements, support contracts, and feature needs before ordering the final configuration.
N9K-C9504 deployments require compatible rack space, power feeds, grounding, supervisors, system controllers, fan trays, power supplies, fabric modules, line cards, blanks for unused slots where required, optics or cables, and management access. The 7 RU chassis depth of 33.15 inches should be checked against cabinet depth, airflow direction, and service-clearance requirements.
UK buyers can purchase N9K-C9504 through ORM Systems as a Cisco enterprise hardware reseller. The buying process should define the required condition, chassis accessories, power supply type, fan trays, supervisors, fabric modules, and line cards. Clear configuration details help ORM Systems quote the correct Nexus 9504 chassis package for deployment or spares.
ORM Systems supports international purchasing requirements for enterprise hardware, including Cisco Nexus chassis orders where export, logistics, and destination rules allow shipment. International buyers should provide the delivery country, required condition, target delivery date, and full bill of materials so the N9K-C9504 quote reflects packaging, handling, and cross-border logistics.
