N9K-C9508-B3R8Q is an eight-slot modular data center switch bundle supplied with four N9K-X9464TX line cards. Each N9K-X9464TX provides 48 ports of 1/10GBASE-T connectivity and four 40G QSFP+ ports, combining copper server connections and optical aggregation links within the installed configuration. The bundle is populated rather than an empty chassis awaiting its initial line cards. Base NX-OS supports Layer 2+ operation, with advanced routing dependent on separate software entitlements. The Cisco Nexus 9508 belongs to the Nexus 9000 family and uses a chassis architecture rather than a fixed access-switch enclosure. N9K-C9508-B38Q supplies three power modules instead of this bundle's six, making the supplied power-module inventory an important distinction when matching an existing build.
N9K-C9508-B3R8Q price for new stock is $155,925.00. N9K-C9508-B3R8Q refurb price is $90,088.95. N9K-C9508-B3R8Q is in stock and available for next-day dispatch. (terms applied)

Static routing and HSRP provide baseline routed connectivity without an additional feature license; OSPF, BGP, IS-IS, EIGRP and PIM require appropriate paid entitlements. Two state-synchronized supervisor modules manage switch operations through an active-standby arrangement, and the supervisors must be the same type. N9K-C9508-B3R8Q supports management through serial console and Ethernet connectivity, including CLI access over SSH or Telnet and automation through NX-API. Rear-mounted fabric modules connect the line cards, while the chassis accommodates eight power supplies and six fabric modules. Power redundancy supports combined, n+1, n+n and input-source configurations, so the selected mode must match the installed component load. Port-side intake establishes the cooling direction, and blank cards must cover unused fabric-module slots to preserve airflow. The 0°C to 40°C operating range also constrains placement in warm equipment rooms and should be checked against the intended rack environment.
Order N9K-C9508-B3R8Q in new sealed or certified refurbished condition, and specify the complete component inventory and required fiber connections on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, optics bay and module bay recognition, PSU and fan status, and clean boot; firmware is verified and configuration wiped to factory default. ORM coverage is up to 3-year extended for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's chassis warranty is 1-year limited hardware, while included N9K-X9464TX coverage ended July 31, 2022. Enterprise and volume orders can use accepted POs, Net-30 for government, and RMA with advance replacement.
| Key Specs | Key Spec Values |
|---|---|
Operating System | Cisco NX-OS |
Port Configuration | Four N9K-X9464TX cards: 48x1/10G and 4x40G each |

When a lab must reproduce an existing modular switch build, the two system controllers matter separately from the supervisors: chassis power and fan management is offloaded to those controllers. Specify the controller inventory and validate the staged hardware inventory against the intended production configuration before the purchase order.
When a maintenance program needs a pre-staged spare across more than one region, ORM supports stock and RMA handling in the UK, EU, US and MEA. Keep the spare's component inventory aligned with the installed system, and specify the required condition and destination on the purchase order.
Current Cisco coverage for every component
The included N9K-X9464TX line cards passed their last date of support on July 31, 2022. Chassis support does not restore Cisco coverage for those discontinued cards.
100G uplinks without hardware changes
The included N9K-X9464TX line cards provide 40G QSFP+ uplinks, not 100G. A 100G configuration requires different line cards and compatible fabric modules.

N9K-C9508-B3R8Q identifies a Nexus 9000 eight-slot chassis bundle: N9K identifies the family, C9508 identifies the eight-slot chassis, and B3R8Q identifies this bundled configuration. The bundle contains two supervisors, four fabric modules, two system controllers, six power supplies, four N9K-X9464TX line cards and eight bidirectional optical modules.
N9K-C9508-B3R8Q is managed through the NX-OS CLI using a serial console, SSH or Telnet, with NX-API available for automation. Supervisor management connectivity includes a 10/100/1000-Mbps Ethernet port. Configure the intended management access during staging and keep the management network separate from the installed line cards' server-facing connections.
N9K-C9508-B3R8Q contains discontinued N9K-X9464TX line cards whose end-of-sale date was August 1, 2017, and whose Cisco support ended July 31, 2022. These component milestones remain relevant independently of chassis availability. New sealed condition does not restart the line cards' Cisco support period or change those published end dates.
ORM offers N9K-C9508-B3R8Q new sealed or certified refurbished, with up to 3-year extended coverage for new units and up to 1 year for refurbished units. Returns are 30 days on every condition; terms apply. Cisco's chassis warranty is 1-year limited hardware, but included N9K-X9464TX line cards ended Cisco support on July 31, 2022.
N9K-C9508-B3R8Q uses NX-OS licensing separately from the hardware bundle. DCN Essentials, DCN Advantage and DCN Premier subscriptions have a minimum three-year term; DCN Advantage perpetual and NX-OS Advantage perpetual options also exist. Perpetual entitlements are not portable between devices. Match the entitlement to the software release and features being ordered.
N9K-C9508-B3R8Q includes four N9K-X9464TX line cards, each providing 48 ports of 1/10GBASE-T connectivity and four 40G QSFP+ ports. Across the four supplied cards, that is 192 copper ports and 16 optical cages. These connections belong to the installed line cards rather than fixed ports on the chassis itself.
The Cisco Nexus 9508 requires 13 rack units and uses a chassis measuring 577.8 mm high, 445 mm wide and 806.7 mm deep. N9K-C9500-RMK= is the rack mounting kit for this chassis. Confirm the mounting kit and rack clearances on the order rather than treating the bundle as a fixed 1U switch.
N9K-C9508-B3R8Q includes eight bidirectional optical modules alongside four N9K-X9464TX line cards, each with four 40G QSFP+ cages. The included optical quantity does not populate every cage. Confirm the optical module part numbers, fiber connections and required link quantity against the final configuration before placing the purchase order.
N9K-C9508-B3R8Q includes six power supply modules in a chassis with eight power supply bays. N9500 power configurations support combined, n+1, n+n and input-source redundancy modes. The usable redundancy depends on installed component demand, so confirm supply part numbers, input type, power cords and the intended redundancy mode before ordering.
N9K-C9508-B3R8Q includes six power supply modules, while N9K-C9508-B38Q includes three. That difference changes the starting power-module inventory for an existing configuration. Buyers reproducing the six-module legacy build should match the former bundle; buyers maintaining the three-module build should match the latter rather than assuming the bundle inventories are identical.
N9K-C9508-B3R8Q uses an eight-slot chassis, while N9K-C9504 is a four-slot chassis. The line-card slot count sets their different expansion limits. The eight-slot configuration suits buyers matching a larger installed modular build; the four-slot chassis suits requirements that fit within four line-card positions and a separately specified component configuration.
N9K-C9508-B3R8Q includes four N9K-X9464TX line cards, while N9K-C9508-B2R8Q includes four N9K-X9564TX line cards. Both are legacy component configurations: N9K-X9464TX support ended July 31, 2022, and N9K-X9564TX support ended May 31, 2023. Each bundle suits sparing the corresponding installed line-card inventory, not selecting a current supported refresh.
Static routing and HSRP are available with the base NX-OS configuration without an additional feature license. OSPF, BGP, IS-IS, EIGRP and PIM belong to paid feature entitlements rather than the bare hardware bundle's included rights. Specify licensing together with the intended NX-OS release; hardware capability alone does not establish entitlement to advanced routing.
