C9500-16X-2Q-A combines 16 fixed 1/10 Gigabit Ethernet SFP/SFP+ ports with two modular 40G QSFP+ uplinks in a managed Layer 3 aggregation switch. Network Advantage accompanies this 1U rack-mount configuration for enterprise campus core and distribution connections. Unlike the discontinued C9500-16X-A base configuration, this bundle includes C9500-NM-2Q. Cisco Catalyst 9500 Series switches occupy the fixed core-switching role within the Catalyst 9000 family. This fiber-oriented configuration aggregates connections from surrounding network devices rather than providing powered copper endpoint access. The network tier adds advanced routing, segmentation, multicast and security capabilities, so the hardware configuration and software entitlement must match the intended network design.
C9500-16X-2Q-A price for new stock is $9,946.65, a 47% saving from the Cisco list price of $18,769.00. C9500-16X-2Q-A refurb price is $3,794.18. C9500-16X-2Q-A is in stock and available for free next-day delivery. (terms applied)

480 Gbps maximum switching capacity defines the aggregate switching ceiling, while 360 Mpps maximum forwarding performance defines packet-processing capacity. OSPFv2, OSPFv3, EIGRP, EIGRPv6, IS-ISv4, BGPv4 and BGPv6 provide dynamic routing, with PIM-SM, PIM-SSM and PIM-BIDIR for multicast. C9500-16X-2Q-A carries 16 GB of DRAM and 16 GB of flash for software execution and local image storage. The UADP 2.0 forwarding engine accommodates 64000 MAC addresses, with resource allocations dependent on the selected forwarding template. IPv4 scale reaches separate maxima of 64000 indirect routes and 80000 host routes, not a simultaneous combined total. The embedded WebUI supports local administration, while network CLI access and programmable interfaces support operational tooling. MACsec supports 256-bit AES-GCM encryption, but WAN MACsec is unavailable. Five FAN-T4-R fans move air from front to back. The standard PWR-C4-950WAC-R leaves the second internal supply bay available for optional redundancy.
ORM Systems supplies C9500-16X-2Q-A new sealed or certified refurbished, with up to a three-year extended warranty on new orders and up to one year on certified refurbished orders; 30-day returns apply to every condition, terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, optics bay recognition, module bay recognition, PSU status and fan status; firmware is verified and configurations are wiped to factory default. Specify the condition, quantity and required supplied components on the PO. Enterprise and volume POs are accepted, government buyers can use Net-30, and RMA with advance replacement is supported across UK, EU, US and MEA stock/RMA coverage.

Deploy the C9500-16X-2Q-A Catalyst 9500 16-Port 10G 2-Port 40G Switch as the core/distribution layer in a 10,000-user enterprise campus. Sixteen 10G ports aggregate access-layer switches while dual 40G uplinks connect to the data center fabric. The result is wire-speed routing, sub-microsecond latency, automated policy enforcement with Cisco DNA Center, and a 50% reduction in provisioning time—delivering scalable, resilient campus connectivity.
Integrate the C9500-16X-2Q-A Catalyst 9500 16-Port 10G 2-Port 40G Switch as leaf nodes in a spine-leaf topology to connect 16 server racks at 10G and provide dual 40G uplinks to spine switches. Its 1.28Tbps switching capacity, hardware-based VXLAN support, and low-latency forwarding accelerate east-west traffic, boost VM migration speeds by 30%, and ensure consistent microsegmentation at scale.
Centralize connectivity for 12 regional branches using the C9500-16X-2Q-A Catalyst 9500 16-Port 10G 2-Port 40G Switch at a regional aggregation hub. Terminate encrypted IPsec tunnels on each 10G port and leverage integrated Cisco TrustSec and MACsec for end-to-end data protection. This architecture reduces WAN costs by 25%, simplifies policy management via Cisco ISE, and enhances compliance with built-in audit‐ready security controls.
When consolidating routed VLAN gateways onto a campus aggregation device, treat logical-interface scale as a purchasing requirement rather than assuming every VLAN receives a gateway. C9500-16X-2Q-A supports 1000 switched virtual interfaces. Specify the required gateway count and the intended forwarding-resource template before issuing the PO.
When staging a unit before installation, plan local console access before loading the network configuration. The USB mini-Type B console uses a five-pin connector, and Windows requires the Cisco USB device driver. Specify the console connection and prepare the staging workstation before ordering hardware for the change window.
When replenishing spare inventory for an existing installation, include chassis slot covers in the receiving checklist. An unused power-supply position requires PWR-C4-BLANK to preserve airflow. Match the replacement's supplied components to the stored spare configuration, including covers retained with existing equipment, before issuing the purchase order.
25G aggregation connections
C9500-16X-2Q-A fixed ports stop at 10G. Current replacement C9500-24Y4C provides 24 native 1/10/25G ports, so selecting that replacement also changes the required port count.
100G backbone uplinks
C9500-NM-2Q provides two 40G ports, not 100G. Current replacement C9500-24Y4C offers four 40/100G uplinks plus 24 downlinks, changing both uplink architecture and chassis port layout.
Cisco support beyond April 2031
Cisco service for C9500-16X-2Q-A ends April 30, 2031. Current replacement C9500-24Y4C changes the port layout to 24 downlinks and four fixed uplinks.

C9500-16X-2Q-A breaks down as C9500 for Catalyst 9500, 16X for the 16-port 10G configuration, 2Q for the two-port 40G network-module bundle, and A for Network Advantage. The bundle's C9500-NM-2Q supplies the uplinks; this is not the base chassis-only ordering configuration.
C9500-16X-2Q-A supports the embedded WebUI, CLI over SSH or Telnet, RJ-45 or USB console access, and SNMP. Cisco Catalyst Center and Meraki cloud monitoring provide centralized visibility; NETCONF, RESTCONF and gNMI/gNOI support automation. Select the management mode and verify its software and entitlement requirements before commissioning.
Yes, C9500-16X-2Q-A is discontinued following its April 30, 2026 end-of-sale date. Software maintenance releases end April 30, 2027, and the last date of support is April 30, 2031. C9500-24Y4C is the current replacement, while Cisco IOS XE 17.18 is the final supported extended-maintenance release.
ORM Systems offers C9500-16X-2Q-A new sealed or certified refurbished. New orders include up to a three-year extended warranty; refurbished orders include up to one year. Both have 30-day returns, terms apply. Cisco's Enhanced Limited Lifetime Warranty is separate, applies to the original owner, and is bounded by the April 30, 2031 last-support date.
C9500-16X-2Q-A includes perpetual Network Advantage. Cisco DNA Essentials/Advantage and Cisco Catalyst Essentials/Advantage subscriptions start at three years; Cisco Networking Subscription offers Cisco Switching Essentials/Advantage with a 36-month minimum. Cisco DNA Advantage must match this PID's Network Advantage entitlement. Assign the subscription and transferred entitlements to the purchasing organization's Smart Account.
No, C9500-16X-2Q-A can continue operating with its perpetual Network Advantage capabilities after the add-on subscription expires. Renew the add-on to retain its subscription features, or deactivate the add-on and reload the switch to operate with the base license. Subscription expiry and perpetual network-license entitlement are separate considerations.
Yes, C9500-16X-2Q-A includes C9500-NM-2Q, which supplies two 40G QSFP+ uplink connections. Those connections come from the removable C9500-NM-2Q rather than fixed QSFP cages on the chassis. Specify the complete bundle when checking supplied components, and match the intended uplink connectivity to the module configuration.
No, C9500-16X-2Q-A ships with one PWR-C4-950WAC-R and an available second internal supply bay. Order another PWR-C4-950WAC-R when AC power redundancy is required. Match the power-source arrangement to the installed supplies and include both units explicitly on the order rather than assuming the redundant configuration ships as standard.
C9500-16X-2Q-A supports RIPv2, RIPng, OSPFv2, OSPFv3, EIGRP, EIGRPv6, IS-ISv4, BGPv4 and BGPv6, plus PIM-SM, PIM-SSM and PIM-BIDIR multicast routing under Network Advantage. Forwarding-resource allocations depend on the selected template. Confirm the intended unicast and multicast design before assigning route-scale requirements to the hardware configuration.
Yes, C9500-16X-2Q-A supports Cisco StackWise Virtual for a two-switch system with Network Advantage. C9500-NM-2Q ports can carry StackWise Virtual and dual-active-detection links on supported software. Reserve connections for the inter-switch design before assigning the remaining module ports to network uplinks, and verify the intended software configuration.
Yes, the Catalyst 9500 16-port 10G switch uses a full-width Rack-Mount 1U chassis measuring 43.9 mm high, 444.5 mm wide and 546.6 mm deep. Its maximum listed weight is 10.7 kg with two power supplies. Check rack depth and equipment-support requirements before specifying the installation components.
C9500-16X-2Q-A includes C9500-NM-2Q with two 40G ports, whereas C9500-16X-A is the Network Advantage base configuration without that bundled module. Both are discontinued. The bundle matches existing spare requirements that include 40G uplinks; the base configuration matches installations where the required network module is already supplied separately.
C9500-16X-2Q-A includes Network Advantage, whereas C9500-16X-2Q-E includes Network Essentials; both bundles include C9500-NM-2Q. Network Advantage adds advanced routing, segmentation, multicast, scale and security. Both are discontinued. The Advantage bundle suits existing deployments requiring that tier; Essentials suits deployments whose required capabilities remain within its network-license tier.
C9500-24Y4C supports native 25G connections, whereas C9500-16X-2Q-A fixed ports reach 10G. C9500-24Y4C is the current successor; C9500-16X-2Q-A is discontinued. The older bundle matches existing 10G spare configurations, while the successor suits refresh projects requiring 25G aggregation and requires selection of the appropriate software tier.
No, Cisco C9500-16X-2Q-A-RF is Cisco Refresh remanufactured hardware, not ORM certified refurbished hardware. ORM certified refurbished units are inspected and bench-tested, with firmware verified and configurations wiped to factory default. Specify the required refurbishment condition and software entitlements independently rather than treating the two refurbishment programs as interchangeable.
