C9500-40X-2Q-A is a managed Layer 3 core and aggregation switch combining 40 fixed 1/10G SFP/SFP+ interfaces with a bundled C9500-NM-2Q providing two 40G QSFP+ uplinks. Its full-width 1U chassis concentrates optical connections from downstream switches rather than supplying PoE to copper endpoints. Unlike the discontinued C9500-40X-2Q-E with Network Essentials, this bundle includes Network Advantage for advanced routing and segmentation. The Cisco Catalyst 9500 Series separates the fixed interface bank from removable uplink hardware, making the complete bundle designation important when matching an installed configuration. The included C9500-NM-2Q distinguishes this order from an unbundled chassis with an empty uplink bay.
C9500-40X-2Q-A price for new stock is $7,938.00, a 79.4% saving from the Cisco list price of $38,609.00. C9500-40X-2Q-A refurb price is $2,971.50. C9500-40X-2Q-A is in stock and available for free next-day delivery. (terms applied)

960 Gbps switching capacity and 720 Mpps forwarding rate establish the traffic envelope for aggregation. OSPF, EIGRP, BGPv4, and IS-IS support dynamic routing, while PBR, VRRP, and HSRP cover policy and gateway functions under the included network tier. C9500-40X-2Q-A carries 16 GB of DRAM and 16 GB of flash for its operating environment. The UADP 2.0 forwarding architecture allocates hardware resources by configuration; the distribution allocation accommodates 64,000 IPv4 longest-prefix-match entries separately from 48,000 IPv4 host routes. CLI and embedded WebUI provide device management, while NETCONF/YANG and RESTCONF expose automation interfaces. StackWise Virtual joins two members as one logical switching system. 850W maximum system consumption informs electrical planning and is distinct from the output rating of PWR-C4-950WAC-R. Five FAN-T4-R cooling fans move air from front to back, requiring ventilation clearance. This Catalyst 9000 family member does not offer native 100G uplinks.
Specify C9500-40X-2Q-A as new sealed or certified refurbished, and confirm the itemized configuration and software entitlements before issuing the PO. Certified refurbished units are inspected and bench-tested for rated-speed port links and optics bay recognition; firmware is verified and configurations are wiped to factory default. ORM warranty coverage is up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units; 30-day returns cover every condition, with terms applying. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement across UK, EU, US, and MEA.

When an installed fleet needs a matching staging unit, software compatibility becomes a purchase constraint: IOS XE 17.18.1 is the final software maintenance release for this hardware. Reproduce the intended configuration before release to production, and specify the required image and entitlement assignment on the purchase order.
When a multisite order spans US and UK facilities, specify CAB-TA-NA for North American mains connections and CAB-TA-UK for UK connections rather than leaving the regional selection implicit. Each site should confirm its receptacle and electrical requirements before the purchase order fixes the required CAB-TA-NA or CAB-TA-UK quantity.
Native 25G aggregation connections
C9500-40X-2Q-A has 10G fixed interfaces rather than native 25G. Current successor C9500-48Y4C provides 48 native 1/10/25G interfaces, changing both connection speed and fixed-port density.
Direct PoE attachment of endpoints
C9500-40X-2Q-A provides fiber-facing interfaces rather than powered RJ-45 access ports. Direct PoE attachment of phones, access points, or other powered copper endpoints is unavailable.
Cisco support beyond April 2029
C9500-40X-2Q-A reaches its last date of Cisco support on April 30, 2029. C9500-48Y4C is the current migration model and changes the interface configuration.

C9500-40X-2Q-A identifies a Catalyst 9500 bundle: C9500 names the series, 40X identifies the 40-port 1/10G configuration, 2Q identifies the included two-port 40G network module, and A identifies Network Advantage. Keep every segment on the purchase order because the base chassis, uplink bundle, and network license are separate ordering distinctions.
CLI and embedded WebUI manage C9500-40X-2Q-A at the device level, while NETCONF/YANG and RESTCONF provide automation interfaces. Catalyst Center provides centralized management through the appropriate subscription. Select the intended management workflow and confirm software compatibility before assigning entitlements; the perpetual network license does not require deploying a controller.
C9500-40X-2Q-A is discontinued: its end-of-sale date was April 30, 2024, and its last date of Cisco support is April 30, 2029. C9500-48Y4C is the migration model. Existing contract eligibility remains separate from hardware availability, so confirm service status before committing to a support-dependent deployment.
Network Advantage is perpetual on C9500-40X-2Q-A. Cisco DNA Essentials and Cisco DNA Advantage, or Catalyst Essentials and Catalyst Advantage subscriptions, start at three years; this PID pairs with Advantage. Unified licensing offers Cisco Switching Essentials and Cisco Switching Advantage with a 36-month minimum and compatible software. Establish Smart Account entitlement handling before ordering.
C9500-40X-2Q-A includes 40 fixed 1/10G SFP/SFP+ ports plus two 40G QSFP+ uplinks on the bundled C9500-NM-2Q. The C9500-NM-2Q is included in this bundle, unlike the unbundled base configuration. Specify compatible transceivers and fiber for the intended links rather than treating interface cages as populated optical connections.
StackWise Virtual supports two C9500-40X-2Q-A switches as one logical switching system with compatible software and Network Advantage entitlement. Multichassis EtherChannel can connect downstream equipment across both members. Reserve inter-switch connectivity separately from production connections, and confirm the intended software release and link configuration before finalizing the equipment order.
PWR-C4-950WAC-R is the default AC power supply for C9500-40X-2Q-A; redundancy depends on the supplied configuration rather than merely having two bays. The original standard configuration includes one PWR-C4-950WAC-R. Confirm the installed quantity on the quote, and include PWR-C4-950WAC-R/2 when the order requires a redundant configuration.
C9500-40X-2Q-A supports OSPF, EIGRP, BGPv4, and IS-IS with Network Advantage, alongside PBR and gateway redundancy functions. Hardware routing resources depend on the selected allocation, so longest-prefix-match entries and host routes are separate limits. Match the required routing and segmentation functions to the permanent entitlement rather than assuming an automation subscription changes hardware scale.
C9500-40X-2Q-A includes Network Advantage, while discontinued C9500-40X-2Q-E includes Network Essentials with the same bundled uplink arrangement. Advantage adds BGP, EIGRP, IS-IS, and network segmentation functions. The Advantage bundle suits advanced-routing requirements; the Essentials variant matches an existing installation whose required functions remain within its lower network tier.
C9500-40X-2Q-A bundles C9500-NM-2Q for two 40G uplinks; discontinued C9500-48X-A bundles C9500-NM-8X for eight additional 10G ports. Both retain the same fixed interface bank. The former matches 40G aggregation connections, while the latter matches an installed design requiring more individual 10G connections rather than fewer higher-speed uplinks.
C9500-40X-2Q-A uses fixed 1/10G interfaces, while its current successor C9500-48Y4C supports native 1/10/25G connections. Migration therefore involves more than replacing a license or an uplink module. The discontinued bundle matches an existing 10G equipment standard; C9500-48Y4C suits a refresh requiring native 25G connectivity.
ORM Systems offers C9500-40X-2Q-A new sealed or certified refurbished. ORM coverage is up to a 3-year extended warranty for new units and up to 1 year for refurbished units, with 30-day returns on either condition; terms apply. Cisco's separate Enhanced Limited Lifetime Warranty is eligibility-dependent, and Cisco service ends April 30, 2029.
