Modular Switching for Data Center Aggregation
N9K-C9508-B3 is an eight-slot modular data center switch chassis bundle with Layer 2+ functionality in base NX-OS and additional routing capabilities available through software licensing. Network interfaces come from separately selected line cards rather than fixed access or uplink ports. The N9500 architecture connects line cards directly to fabric modules without a midplane and uses front-to-back airflow. The bundle includes one supervisor, three power supplies, two system controllers, four fabric modules, and three fan trays. N9K-C9508-B2 differs by including six fabric modules. For a Nexus 9508 chassis deployment, the component inventory, operating mode, and interface requirements must be specified together rather than treating the bundle as a fixed-port switch.
N9K-C9508-B3 price for new stock is $100,375.32. N9K-C9508-B3 refurb price is $51,181.20. N9K-C9508-B3 is in stock and available for next-day dispatch. (terms applied)

Technical Details
Static routing, SVIs, and HSRP are available in base NX-OS without an additional feature license, covering basic inter-VLAN forwarding and first-hop redundancy. OSPF, BGP, and EIGRP require the appropriate software entitlement rather than following automatically from the chassis hardware. N9K-C9508-B3 supports management through the supervisor's serial and Ethernet management connections; NX-API automation and DCNM management are available in NX-OS deployments. System controllers supervise power supplies and cooling while offloading chassis management functions from the control plane. Eight power-supply positions accommodate expansion, but redundancy depends on installed load and the selected power mode. Fabric modules must be the same type, and empty fabric positions require N9K-C9508-FM-CV blanks to preserve airflow. Interface capability and operating power depend on the installed components; an individual supply's output rating is not the chassis's power consumption.
Ordering
ORM Systems offers N9K-C9508-B3 new sealed and certified refurbished, with refurbished units inspected and bench-tested for power-on and POST, clean boot, module bay recognition, PSU status, and fan status; firmware is verified and configuration is wiped to factory default.

Best For
Rack Consolidation Planning
When an aggregation refresh introduces a modular chassis, reserve 13 rack units before finalizing cabinet allocation. Mounting hardware and service access belong in the installation plan alongside the electrical requirements. Include N9K-C9500-RMK= rack mounting hardware in the equipment checklist and verify the cabinet arrangement before issuing the purchase order.
Control Plane Redundancy
When standardizing redundant control planes across a data center, use two supervisors of the same type in the chassis. N9500 synchronizes active-standby supervisor state rather than combining dissimilar supervisors. Check both supervisor identities and the intended software release together, then specify the matched pair on the purchase order.
Not Suitable If
Fixed Ethernet ports out of box
N9K-C9508-B3 supplies chassis infrastructure rather than line cards. Network connections require separately specified line cards and compatible media; the bundle does not provide fixed data ports.
Dynamic routing without software licensing
Base NX-OS provides static routing rather than licensed OSPF or BGP. Specify an appropriate entitlement, such as NXOS-AD-M8-16, when those protocols are required.

Questions & Answers
What does the N9K-C9508-B3 part number mean?
N9K-C9508-B3 identifies a Nexus 9508 chassis bundle: N9K denotes the Nexus 9000 family, C9508 identifies the eight-slot chassis, and B3 selects one supervisor, three power supplies, two system controllers, four fabric modules, and three fan trays. B3 identifies the hardware bundle rather than a software license tier.
How is N9K-C9508-B3 managed?
N9K-C9508-B3 supports NX-OS management through the supervisor's serial and Ethernet management connections, NX-API automation, and DCNM; Cisco ACI supplies an alternative policy-based operating mode. The selected mode and installed hardware must agree. Specify the intended operating mode and management connections when assembling the complete chassis configuration.
What is the lifecycle status of the Nexus 9508 chassis?
Cisco has not announced an end-of-sale date for Nexus 9508. N9K-C9508-B3 chassis lifecycle must be distinguished from individual supervisors, fabric modules, and line cards, which can have separate retirement milestones. Service planning therefore needs to account for every installed component rather than treating the chassis name as a universal support deadline.
Which licensing paths are available for N9K-C9508-B3?
DCN Essentials, Advantage, or Premier subscriptions and perpetual NX-OS Advantage are licensing paths for N9K-C9508-B3. Subscription terms are 3, 5, or 7 years; NXOS-AD-M8-16 is the perpetual option. Subscription entitlements expire with their term, while perpetual rights remain device-bound. The hardware bundle name does not establish the purchased software entitlement.
What condition and warranty options does ORM Systems offer for N9K-C9508-B3?
ORM Systems offers N9K-C9508-B3 new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. All conditions include 30-day returns, terms apply. Cisco's separate platform warranty is a 1-year limited hardware warranty. Refurbished units are inspected and bench-tested.
Can N9500 power supplies operate redundantly?
N9500 supports redundant hot-swappable power supplies, but available redundancy depends on the installed configuration's power requirement and selected power mode. N9K-C9508-B3 includes three supplies rather than filling all eight chassis positions. Verify supply identities and load before specifying combined, N+1, N+N, or input-source redundancy for the completed configuration.
Does N9K-C9508-B3 include Ethernet line cards or fixed uplinks?
N9K-C9508-B3 has no fixed data ports; network connections require separately ordered line cards. Neither an eight-slot chassis designation nor a fabric-module quantity specifies Ethernet port density. Match each proposed line card to its fabric, software mode, transceivers, and required link speed before completing the configuration and purchase order.
What is the difference between N9K-C9508-B3 and N9K-C9508-B2?
N9K-C9508-B3 includes four fabric modules, whereas N9K-C9508-B2 includes six fabric modules. Both are eight-slot chassis bundles, but their initial fabric populations differ. N9K-C9508-B3 suits a design specified around four fabric modules; N9K-C9508-B2 suits a design requiring six fabric modules from the initial purchase.
What is the difference between N9K-C9508-B3 and N9K-C9508-B3R8Q?
N9K-C9508-B3 ships with one supervisor, while N9K-C9508-B3R8Q includes two supervisors. A redundant control-plane design must account for that starting population rather than assuming every chassis bundle supplies a pair. N9K-C9508-B3 suits a single-supervisor specification; N9K-C9508-B3R8Q suits an order requiring two supervisors included in the bundle.
What is the difference between N9K-C9508-B3 and N9K-C9504-B3?
N9K-C9508-B3 offers eight line-card slots, while N9K-C9504-B3 offers four line-card slots. The difference is chassis expansion capacity rather than a fixed Ethernet port count. N9K-C9508-B3 suits an eight-slot equipment plan; N9K-C9504-B3 suits a four-slot plan requiring a smaller chassis and fewer expansion positions.
