C9500-24Y4C-1A is a managed Layer 3 fiber switch with 24 fixed 1/10/25G SFP28 ports and four fixed 40/100G QSFP28 uplinks, supplied with Network Advantage. Its 1U rack-mount chassis belongs to the Catalyst 9500 family and serves enterprise core and aggregation connections. The built-in uplink arrangement requires no removable network card to expose those interfaces. This 24-port 25G aggregation switch accommodates fiber connections operating at different interface rates within the same chassis. C9500-24Y4C-1E retains the port arrangement but uses Network Essentials instead of Network Advantage. Within the Catalyst 9000 family, this configuration handles fiber aggregation rather than powered endpoint access: the chassis carries Ethernet traffic but does not supply PoE.
C9500-24Y4C-1A price for new stock is $41,474.87. C9500-24Y4C-1A refurb price is $19,633.95. C9500-24Y4C-1A is in stock and available for next-day dispatch. (terms applied)

2000 Gbps switching capacity sets the standalone fabric ceiling, with line-rate performance specified for packets of 187 bytes and larger. 1000 Mpps forwarding capacity provides the packet-rate limit to assess alongside bandwidth. BGPv4, BGPv6, OSPFv2, OSPFv3, EIGRP, EIGRPv6, and IS-ISv4 support routed deployments under Network Advantage, while PIM-SM and PIM-SSM handle multicast routing. C9500-24Y4C-1A uses UADP 3.0 forwarding silicon with 16 GB of DRAM and 16 GB of flash for system operation and image storage. Hardware limits include 256000 combined direct and indirect IPv4 routes and 82000 MAC addresses; available allocation depends on the selected resources and route mix. The embedded WebUI handles local provisioning and troubleshooting without a separate management application. Four C9K-T1-FANTRAY fan units cool the chassis, while an optional second internal power supply enables power redundancy. There are no native RJ-45 access ports.
ORM Systems supplies C9500-24Y4C-1A new sealed or certified refurbished, with up to a 3-year extended warranty on new hardware and up to 1 year on certified refurbished hardware; both conditions have 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and optics bay recognition; firmware is verified and configurations are wiped to factory default. Specify condition, quantity, power accessories, and license entitlements on the purchase order. PO accepted, Net-30 for government, and RMA with advance replacement support enterprise and volume orders across UK, EU, US, and MEA stock and RMA regions.

Operating System | Cisco IOS XE |
License Tier | Network Advantage |
Port Configuration | 24 x 1/10/25G SFP28 / 4 x 40/100G QSFP28 |

When a routed-core refresh changes the mix of host routes, multicast entries, and access-control rules, validate the intended SDM configuration before ordering. Custom resource allocation requires Cisco IOS XE 17.3.1 or later, so specify the software release and required configuration during procurement.
When a multi-site rollout requires asset tags to match an inventory policy, decide the RFID configuration before ordering hardware. C9500-RFID selects the tag and C9500-RFID-NONE omits it; the tag cannot be installed later. Specify the required selection consistently across the purchase order.
400G links to the core
The four uplinks stop at 100G. C9500X-28C8D-A offers eight 400G-capable ports and changes the downlink configuration to 28 100G-capable ports.
Native copper ports with PoE
The switch provides fiber-facing cages, not native RJ-45 access ports or PoE output. Powered copper endpoints require separate access-switch hardware rather than this aggregation model.

C9500-24Y4C-1A identifies a Catalyst 9500 switch with 24 1/10/25G ports, four 40/100G ports, and Advantage licensing. C9500 names the family, 24Y identifies the downlink configuration, 4C identifies the uplink configuration, and 1A identifies the one-year Cisco DNA Advantage hardware bundle.
C9500-24Y4C-1A is managed through the Cisco IOS XE CLI or embedded WebUI, with Catalyst Center integration and Meraki dashboard cloud monitoring also available. WebUI comes with the default image; centralized tools have separate software and deployment requirements that should be specified with the order.
C9500-24Y4C-1A combines perpetual Network Advantage with one-year Cisco DNA Advantage. Standard Cisco DNA Essentials or Advantage and Catalyst Essentials or Advantage subscriptions start at three years. Cisco Networking Subscription offers Cisco Switching Essentials or Cisco Switching Advantage with a 36-month minimum. Confirm the licensing path and Smart Account before ordering.
No, C9500-24Y4C-1A does not provide PoE or native powered RJ-45 access ports. Its network connections use SFP28 and QSFP28 cages for fiber-facing aggregation links. Phones, access points, and other powered copper endpoints need a separate source of endpoint power and an appropriate access connection.
C9500-24Y4C-1A has four fixed QSFP28 uplinks supporting 40G or 100G connections. The uplinks are built into the chassis rather than supplied through an optional network card. Select compatible optics or direct-attach assemblies for the required speed, media, connector, and reach of each link.
Yes, compatible Catalyst 9500 switches can use StackWise Virtual to pair two physical switches into one logical switch. The virtual links use Ethernet interfaces, so their interface allocation must be included in the connection plan. Specify a compatible pair and the required interconnects before ordering.
Yes, C9500-24Y4C-1A supports BGPv4, BGPv6, OSPFv2, and OSPFv3 with Network Advantage. EIGRP, EIGRPv6, and IS-ISv4 are also supported. The hardware supports 256000 combined direct and indirect IPv4 routes, subject to resource allocation and prefix combinations rather than an unconditional scale guarantee for every configuration.
Yes, C9500-24Y4C-1A supports redundant power through an optional second internal power supply; the standard hardware configuration includes one supply. Compatible choices include C9K-PWR-650WAC-R, C9K-PWR-650WACL-R, and C9K-PWR-930WDC-R. Specify the installed supply arrangement and the required power-cord region explicitly when ordering hardware.
C9500-24Y4C-1A carries Network Advantage, while C9500-24Y4C-1E carries Network Essentials on the same port configuration. Advantage adds advanced routing, segmentation, multicast, and scale capabilities. Essentials suits deployments using the baseline feature set; Advantage suits buyers whose required functions exceed that baseline.
C9500-48Y4C-1A doubles the 1/10/25G port count from 24 on C9500-24Y4C-1A to 48, while retaining four 40/100G uplinks. The 24-port model fits a smaller fiber-aggregation requirement; the 48-port model suits buyers consolidating more fiber connections into one chassis without changing the uplink speed class.
C9500X-28C8D-A provides eight 400G-capable ports, while C9500-24Y4C-1A provides four 100G-capable uplinks. The former suits buyers specifying higher-speed core interconnects; the latter suits a 25G aggregation design with 100G uplinks. These are different chassis models, not interchangeable license upgrades to the same hardware.
Cisco has not announced an end-of-sale date for Catalyst 9500. C9500-24Y4C-1A is separate from the discontinued C9500-12Q, C9500-24Q, and C9500-40X hardware groups. End-of-life milestones for those models, or for individual Cisco IOS XE releases, do not establish a retirement date for this switch.
C9500-24Y4C hardware replaces discontinued C9500-16X-A, C9500-16X-E, C9500-24X-A, C9500-24X-E, and C6824-X-LE-40G= configurations. The C9500-16X and C9500-24X variants reached end of sale on April 30, 2026. Replacement orders must separately specify the desired license, interface media, and link optics rather than assume an identical configuration.
ORM offers C9500-24Y4C-1A new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Both conditions have 30-day returns; terms apply. Cisco's separate Enhanced Limited Lifetime hardware warranty is bounded by its terms and last date of support.
