N9K-C9504-B2 is a four-slot modular data center switch bundle for aggregation, core and spine deployments. Network connections come from separately specified line cards rather than fixed access ports, so the interface configuration must accompany the chassis selection. The bundle includes one supervisor, three power supplies, two system controllers, six fabric modules and three fan trays, but no line cards. Cisco Nexus 9500 switches support NX-OS and Cisco Application Centric Infrastructure operating modes. Compared with N9K-C9504-B1, the B2 package includes six fabric modules instead of three without changing the four-slot line-card layout. The chassis provides the foundation for a configured switching system rather than a fixed-port switch ready for network connections.

Front-to-back airflow aligns the chassis with a port-side intake cooling layout. System controllers offload chassis-management functions from the supervisor and monitor power supplies and cooling components. N9K-C9504-B2 supports NX-OS hardware-inventory, environmental and module-state commands for checking installed components during staging and troubleshooting. Inventory output identifies component PIDs and serial numbers, while environmental monitoring separates actual power use from allocated capacity. Initial configuration begins through the serial console before the management interface receives its network configuration. NX-API provides an automation interface, and Data Center Network Manager supports centralized operation in NX-OS mode. A second matching supervisor enables an active-standby arrangement; the included single supervisor does not provide supervisor redundancy by itself.
ORM Systems offers N9K-C9504-B2 new sealed and certified refurbished; new units carry up to a 3-year extended warranty, refurbished units up to 1 year, and both have 30-day returns, terms apply. Certified refurbished units are inspected and bench-tested for power-on, POST, clean boot, module bay recognition, PSU status and fan status, with firmware verified and configuration wiped to factory default. Specify the complete bill of materials and condition on the purchase order, including required interface cards, optics and software entitlements. Enterprise and volume orders accept POs, with Net-30 for government and RMA with advance replacement; regional stock and RMA cover the UK, EU, US and MEA.

When standardizing chassis across facilities, each assembly must use a single power type because AC and DC power supplies cannot be mixed within one switch. Map the site's electrical feed to the intended supply configuration, and specify that power type before releasing the purchase order.
When a replacement chassis must be configured before entering a production rack, console access must precede network management setup. The initial serial connection uses 9600 baud, eight data bits, one stop bit and no parity. Include the required console connection and staging instructions on the purchase order.
Fixed network ports included at delivery
N9K-C9504-B2 is a chassis-component bundle without line cards. Network connections require separately specified interface cards and the appropriate optics or copper cabling before deployment.
Dual supervisors included as standard
N9K-C9504-B2 includes one supervisor. Supervisor redundancy requires an additional matching module; the presence of two supervisor positions does not mean both positions ship populated.

N9K-C9504-B2 identifies a Nexus 9504 chassis bundle: N9K-C9504 names the four-slot chassis, while B2 selects one supervisor, three power supplies, two system controllers, six fabric modules and three fan trays. The bundle designation describes the included chassis components rather than an installed Ethernet port configuration.
No, N9K-C9504-B2 includes chassis control, fabric, power and cooling components but does not include line cards. Network interfaces must be specified separately. Include the required interface-card PIDs and compatible optics or copper connections in the configuration so the delivered assembly presents the necessary network ports.
Cisco Nexus 9500 switches provide CLI management through the serial console and management interface, NX-API automation, and centralized NX-OS operation through Data Center Network Manager. Cisco ACI provides a separate policy-based operating mode. Initial local configuration establishes the management connection before remote administration begins.
Cisco has not announced an end-of-sale date for N9500. N9K-C9504-B2 belongs to this modular chassis family, whose individual supervisors, line cards and fabric modules can have separate retirement milestones. Assess the lifecycle of the complete quoted configuration rather than treating a component announcement as retirement of every chassis bundle.
Yes, N9K-C9504-B2 includes three power supplies and supports redundant power operation when the configured load fits the selected reserve capacity. Combined mode provides no reserve, n+1 reserves one supply, and n+n separates active and reserve power sources. Supply count alone does not establish the usable operating budget.
The Nexus 9504 chassis occupies 7 rack units and measures 311 mm high, 445 mm wide and 842 mm deep, including its handles. Confirm rack depth, cable routing and access requirements before installation. The chassis dimensions do not include additional space needed around the equipment for servicing.
N9K-C9504-B2 includes six fabric modules, whereas N9K-C9504-B1 includes three. Both packages include one supervisor, three power supplies, two system controllers and three fan trays. B2 suits an order requiring the six-module fabric population; B1 suits a configuration explicitly sized around the three-module population.
N9K-C9504-B2 provides four line-card slots, while N9K-C9508-B2 provides eight. Both B2 packages include one supervisor, three power supplies, two system controllers, six fabric modules and three fan trays. The four-slot package suits the smaller chassis requirement; the eight-slot package accommodates a larger line-card configuration.
N9K-C9504-B2 includes three N9K-C9504-FAN fan trays with port-side intake airflow. Each N9K-C9504-FAN covers two fabric-module positions at the rear of the chassis. Fabric-module access therefore involves the associated N9K-C9504-FAN, and the rack layout must preserve the chassis's front-to-back airflow path.
ORM Systems offers N9K-C9504-B2 new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions include 30-day returns, terms apply. Cisco's separate platform warranty is a 1-year limited hardware warranty.
