C9500-48Y4C-1A is a managed Layer 3 fiber aggregation switch with 48 fixed 1/10/25G SFP28 ports and four fixed 40/100G QSFP28 uplinks in the Network Advantage configuration. The Catalyst 9500 serves enterprise campus core and distribution connections in a rack-mount 1U chassis. Its native fiber interfaces aggregate network equipment rather than supply power to endpoint devices. C9500-24Y4C-A reduces the access-port count to 24 for installations requiring fewer fiber connections. The fixed uplink architecture provides its connections without an additional network card, but it does not offer a removable uplink expansion bay. This configuration suits buyers standardizing on optical aggregation while retaining multiple interface speeds for existing and planned links.
C9500-48Y4C-1A price for new stock is $45,128.40. C9500-48Y4C-1A refurb price is $19,738.95. C9500-48Y4C-1A is in stock and available for next-day dispatch. (terms applied)

3200 Gbps switching capacity accommodates the chassis interface configuration, with line-rate operation specified for packets of 187 bytes and larger. 1000 Mpps forwarding performance provides a separate packet-processing limit to consider when assessing traffic dominated by small frames. OSPFv2, OSPFv3, EIGRP, EIGRPv6, IS-ISv4, BGPv4 and BGPv6 support routed aggregation under Network Advantage; PIM-SM, PIM-SSM and PIM-BIDIR cover multicast routing requirements. C9500-48Y4C-1A uses UADP 3.0 forwarding silicon with 16 GB of DRAM and 16 GB of flash for software operation and image storage. The IPv4 route-table maximum reaches 256000 entries, subject to resource allocation and the prefix mix. MAC address capacity reaches 82000 entries with the appropriate resource configuration. MACsec supports 256-bit AES-GCM protection, while hierarchical QoS provides two scheduling levels. The chassis uses four C9K-T1-FANTRAY units with front-to-back airflow; cooling plans must preserve that airflow path.
ORM Systems offers C9500-48Y4C-1A new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, optics bay recognition, clean boot, PSU status and fan status, with firmware verified and configuration wiped to factory default. Specify the condition, accessory quantities and entitlement requirements on the purchase order before placing the order. New units carry up to a 3-year extended ORM warranty, certified refurbished units carry up to 1 year, and every condition includes 30-day returns, terms apply; Cisco's Enhanced Limited Lifetime hardware warranty remains separate and subject to Cisco end-of-life limits. Enterprise and volume orders can use PO acceptance, government Net-30, RMA with advance replacement and regional stock/RMA across the UK, EU, US and MEA.

When replacing discontinued C9500-40X hardware, treat the purchase as a hardware and entitlement transition rather than assuming the previous configuration transfers unchanged. The C9500-48Y4C hardware is a migration target for that older family. Validate retained optics, connection assignments and software entitlements before specifying the replacement order.
When a multi-site rollout requires RFID-based asset identification, settle that requirement before ordering the hardware. C9500-RFID selects the optional tag, while C9500-RFID-NONE omits it; the tag cannot be installed later after an opt-out. Specify the same RFID selection across the purchase order where a common asset process is required.
When staging container-based applications alongside switching tests, plan local storage as a separate purchase rather than assuming an SSD is included. C9K-F1-SSD-240G is a supported 240 GB option for this chassis. Confirm the application image, software release and required SSD quantity before issuing the purchase order.
Native 200G or 400G uplinks
100G is the maximum fixed uplink speed. C9500X-60L4D-A provides four 400G uplinks, but also changes the access configuration to 60 ports supporting 50G.
Removable uplink expansion modules
The chassis has fixed uplinks and does not accept C9500-NM-8X or C9500-NM-2Q. Additional uplink ports cannot be installed through a network-module bay.

C9500-48Y4C-1A identifies a Catalyst 9500 switch with 48 interfaces supporting 1/10/25G, four interfaces supporting 40/100G, and a one-year Advantage bundle. C9500 identifies the family, 48Y identifies the access configuration, 4C identifies the uplink configuration, and 1A distinguishes the one-year Advantage ordering form from the standard Advantage form.
C9500-48Y4C-1A supports an embedded WebUI, a CLI with SSH access, Cisco Catalyst Center and supported Meraki dashboard management. NETCONF, RESTCONF and gNMI provide programmable interfaces, while out-of-band access uses RJ-45 and USB-mini Type B connections. Dashboard capabilities depend on the software release and applicable licensing rather than replacing those local interfaces.
C9500-48Y4C-1A identifies a one-year Advantage bundle, not the standard three-year DNA offer. Standard Cisco DNA Essentials and Cisco DNA Advantage terms are three, five or seven years. Cisco Networking Subscription offers Cisco Switching Essentials and Cisco Switching Advantage with a 36-month minimum. A Smart Account is required.
The Catalyst 9500 can continue operating with its perpetual network license after the DNA add-on expires. Renew the add-on to retain its subscription capabilities, or deactivate the expired add-on and reload the switch to operate with the base license. Subscription expiration is separate from hardware retirement and does not itself establish a hardware support deadline.
Cisco has not announced an end-of-sale date for Catalyst 9500. The C9500-48Y4C hardware remains distinct from discontinued C9500-40X configurations and from notices covering individual Cisco IOS XE releases. A software-release retirement date does not establish a hardware last date of support for this switch.
ORM Systems supplies C9500-48Y4C-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. Every condition includes 30-day returns, terms apply. Cisco's separate Enhanced Limited Lifetime hardware warranty is subject to its end-of-life limits; refurbished units are inspected and bench-tested.
C9500-48Y4C-1A supports StackWise Virtual, which pairs two switches into one logical system. Front-panel interfaces carry the virtual link and dual-active detection connections. Supported virtual-link interfaces include 10G/25G downlinks and 40G/100G uplinks, so the connection plan must reserve those interfaces rather than allocate every port to other equipment.
C9500-48Y4C-1A uses C9K-PWR-650WAC-R as its default AC supply and supports an optional second supply. Specify C9K-PWR-650WAC-R/2 when ordering the secondary AC unit. A single installed supply does not provide power redundancy, even though the chassis has two internal supply bays.
C9500-48Y4C-1A has 48 SFP28 interfaces supporting 1/10/25G and four QSFP28 uplink interfaces supporting 40/100G. These are fixed chassis interfaces, not ports added by a network module. Select compatible transceivers or direct-attach connections for the required speed, reach and fiber arrangement when specifying the order.
C9500-48Y4C-1A supports OSPFv2/OSPFv3, EIGRP/EIGRPv6, IS-ISv4 and BGPv4/BGPv6 with Network Advantage. RIPv2/RIPng and PIM-SM/PIM-SSM/PIM-BIDIR are also supported. The hardware route-table maximum is 256000 IPv4 routes; actual allocation depends on the selected SDM template and prefix mix, rather than guaranteeing every maximum simultaneously across all features.
Network Advantage on C9500-48Y4C-1A adds advanced routing and segmentation beyond Network Essentials on C9500-48Y4C-E. The access and uplink hardware is unchanged. Choose the Advantage bundle for those network capabilities; the Essentials model serves buyers whose feature requirements stay within the foundational network tier.
C9500-48Y4C-1A provides 48 access interfaces, while C9500-24Y4C-A provides 24 access interfaces supporting the same 1/10/25G speeds. Both retain four fixed 40/100G uplinks. The 48-port configuration serves higher connection counts; the 24-port configuration suits buyers whose required fiber connections fit within the smaller interface count.
C9500-48Y4C-1A provides four uplinks rated to 100G, whereas C9500X-60L4D-A provides four uplinks rated to 400G. Both use fixed uplink ports rather than removable network modules. The former suits 100G aggregation plans; the latter serves buyers specifying 200G or 400G core-facing links.
C9500-48Y4C hardware is the migration target for discontinued C9500-40X and C9500-48X configurations, including C9500-40X-A, C9500-40X-E, C9500-48X-A and C9500-48X-E. C9500-48Y4C-1A adds its one-year Advantage ordering identity to that hardware. Existing optics and software entitlements need separate validation before treating the purchase as a direct replacement.
