N9K-C9508-B1 is an eight-slot modular data center switch bundle whose Ethernet interfaces are supplied through separately selected line cards. The Nexus 9508 enclosure supports core, aggregation, and spine roles rather than providing a fixed set of access ports. Within the Nexus 9000 family, this configuration separates the chassis and common equipment from the traffic-facing interface selection. The closest bundle variant, N9K-C9508-B2, includes six fabric modules instead of three. The purchase decision therefore concerns the required fabric population and complete hardware assembly, not simply a port count. Specify connection types, interface density, compatible line cards, and the intended operating mode together so that the configured assembly matches the network requirement.
N9K-C9508-B1 price for new stock is $93,352.40. N9K-C9508-B1 refurb price is $44,994.60. N9K-C9508-B1 is in stock and available for next-day dispatch. (terms applied)

Static routing and HSRP form the unlicensed NX-OS routing baseline; OSPF, BGP, IS-IS, EIGRP, and PIM require the corresponding software entitlement. N9K-C9508-B1 separates supervisor processing, system control, and fabric forwarding into modular functions that must be evaluated as a complete assembly. System controllers manage power supplies and fan trays, while the supervisor provides serial and Ethernet management connections. Standalone operation supports DCNM management and NX-API automation; ACI operation uses APIC policy control. Redundant supervisors must be the same type. ACI spine supervisor standby is stateless rather than state-synchronized: a supervisor switchover resets the modules, so the operational acceptance plan must account for that behavior. Power redundancy also depends on the installed module load and selected redundancy mode, rather than following automatically from the presence of multiple supplies. These dependencies make the actual component inventory and intended software release important acceptance criteria.
Specify N9K-C9508-B1 as new sealed or certified refurbished, with the supplied module inventory recorded on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, module bay recognition, PSU status, and fan status, with firmware verified and configurations wiped to factory default. New units carry up to a three-year extended warranty and certified refurbished units up to one year; every condition has 30-day returns, terms apply, separate from Cisco's one-year limited hardware warranty. Enterprise and volume orders accept POs, government Net-30, and RMA with advance replacement, with regional stock and RMA covering the UK, EU, US, and MEA.

When a maintenance plan calls for a spare modular switch, the B1 package includes one supervisor and two system controllers. Make the spare's component inventory part of the acceptance checklist, and specify the required installed modules and refurbishment condition on the purchase order.
When standardizing installation hardware across sites, N9K-C9500-RMK= is the rack-mount kit for the eight-slot chassis. Include the required kit on each site's packing checklist rather than assuming an existing rack installation supplies it, and confirm mounting hardware quantities before submitting the purchase order.
Ethernet interfaces ready on arrival
N9K-C9508-B1 supplies chassis common equipment rather than Ethernet line cards. A forwarding configuration requires compatible line cards and appropriate transceivers, specified separately on the order.
Dual supervisors included as standard
N9K-C9508-B1 includes one supervisor, so the bundle alone does not provide dual-supervisor redundancy. Both installed supervisors must be the same type.

N9K-C9508-B1 names a Nexus 9000 family bundle built around the eight-slot Nexus 9508 chassis. The B1 package contains one supervisor, three power supplies, two system controllers, three fan trays, and three fabric modules; B1 identifies a hardware bundle rather than a software license tier.
N9K-C9508-B1 is managed through its supervisor, with serial console and Ethernet management connections. NX-OS deployments support DCNM management and NX-API automation; ACI deployments use APIC policy control. Specify the operating mode before selecting software, management integration, and the workflow used to configure the completed assembly.
Cisco has not announced an end-of-sale date for Nexus 9500. Individual chassis variants, supervisors, fabric modules, fans, and line cards have separate lifecycle notices. For an N9K-C9508-B1 order, assess the actual component inventory rather than treating the series name as a single support deadline.
ORM Systems offers N9K-C9508-B1 new sealed or certified refurbished, with up to a three-year extended warranty for new units and up to one year for certified refurbished units. Returns are available for 30 days on every condition; terms apply. Cisco's separate Nexus 9500 warranty is a one-year limited hardware warranty.
DCN Essentials, DCN Advantage, and DCN Premier subscriptions apply to N9K-C9508-B1 in three-, five-, or seven-year terms; NXOS-AD-M8-16 supplies perpetual NX-OS Advantage licensing. Essentials is subscription-only. Perpetual licenses are not portable between devices, so confirm entitlement ownership and account assignment separately from the hardware order.
Nexus 9500 includes static routing, SVIs, and HSRP without an additional license. OSPF, BGP, IS-IS, EIGRP, and PIM are separately licensed NX-OS capabilities. Match routing requirements to the chosen entitlement rather than assuming the B1 hardware-bundle suffix selects or includes a particular software feature tier.
N9K-C9508-B1 includes three power supplies, and the chassis accepts eight. Available power redundancy depends on the installed line cards, fabric modules, and configured redundancy mode. Specify the complete module inventory and required input-source redundancy before finalizing the number, type, and power connections of the supplies.
Nexus 9508 requires 13 rack units and has a chassis depth of 806.7 mm. N9K-C9500-RMK= is the compatible rack-mount kit. Confirm cabinet clearance, mounting compatibility, and installation hardware when preparing the order rather than treating the eight-slot enclosure as a compact fixed-port switch.
N9K-C9508-B1 contains three fabric modules, while N9K-C9508-B2 contains six. Both bundles specify one supervisor, three power supplies, two system controllers, and three fan trays. B1 suits an order specifying the smaller fabric population; B2 suits an assembly requiring six fabric modules in the initial package.
N9K-C9508-B1 provides eight line-card slots, while N9K-C9504 provides four. This difference concerns expansion space rather than a fixed Ethernet port count. The B1 bundle suits an assembly needing eight slots; the four-slot chassis suits a separately configured assembly whose planned card inventory fits four slots.
N9K-C9508-B1 bundles chassis common equipment with the eight-slot enclosure, whereas N9K-C9508 identifies the chassis ordering option. The B1 package specifies a supervisor, power supplies, controllers, fans, and fabric modules. Choose B1 for that package definition or the chassis option when specifying the assembly's common equipment separately.
