C9500-48Y4C is a fixed Layer 3 enterprise core and aggregation switch with 48 native 1/10/25 Gigabit Ethernet SFP28 ports and four built-in 40/100 Gigabit Ethernet QSFP28 uplinks. The non-PoE, rack-mount 1U chassis belongs to the Catalyst 9500 series and connects fiber-based aggregation links within campus networks rather than supplying endpoint power. C9500-24Y4C provides 24 native downlink ports instead, making connection density the distinction for a smaller aggregation requirement. Network Essentials supplies the baseline switching and routed-access capabilities, while Network Advantage unlocks advanced routing, segmentation, multicast, and virtualization. The unsuffixed hardware identifier does not select between those entitlements, so the purchase configuration must identify the required software rights separately.

3200 Gbps switching capacity supports aggregation traffic, with line-rate operation specified for packets of 187 bytes and larger. 1000 Mpps forwarding capacity establishes the separate packet-rate ceiling. OSPF supports up to 1000 routes under Network Essentials; RIP, EIGRP Stub, PBR, VRRP, and PIM Stub multicast are also available, with PIM Stub limited to 1000 routes. C9500-48Y4C uses UADP 3.0 forwarding silicon with 16 GB DRAM and 16 GB flash for control-plane operation and local software storage. Custom resource allocation supports 128000 MAC entries and 256000 total IPv4 routes; those hardware limits do not remove software entitlement restrictions. Within the Catalyst 9000 family, management options include the embedded WebUI and CLI, plus Catalyst Center or Meraki dashboard arrangements. Network Advantage adds BGP, full EIGRP, IS-IS, advanced multicast, and StackWise Virtual; these are not baseline Network Essentials capabilities. Resource allocation must reflect the intended mix of forwarding, security, and visibility functions.
ORM Systems offers C9500-48Y4C new sealed or certified refurbished; refurbished units are inspected and bench-tested, including optics bay recognition, with firmware verified and configuration wiped to factory default. Specify condition, software entitlements, and accessory quantities on the purchase order. New units carry up to a 3-year extended warranty and certified refurbished units up to 1 year; 30-day returns cover every condition, terms apply, while Cisco's separate Enhanced Limited Lifetime Warranty covers the original owner and is limited to five years after manufacturing discontinuance.

Deploy the Catalyst 9500-48Y4C as the central aggregation switch in a large enterprise campus to deliver 40 Gbps uplinks, advanced Layer 3 routing, and nonstop forwarding. This use case drives ultra-low latency, simplifies network operations with Cisco DNA Center automation, and ensures 99.999% availability for mission-critical applications.
Leverage the Catalyst 9500-48Y4C as the SD-Access control-plane node to enforce identity-based micro-segmentation across wired and wireless domains. This deployment enhances compliance by isolating user groups, accelerates threat containment with Cisco TrustSec, and reduces policy-management overhead by up to 70%.
Use the Catalyst 9500-48Y4C at the data center edge to terminate EVPN-VXLAN fabrics and support multi-tenant east-west traffic at 40 Gbps. Customers gain seamless VXLAN fabric extension, predictable performance under high-density workloads, and simplified operational overhead through model-driven programmability.
An aggregation refresh prompted by discontinued C9500-40X hardware needs an interface-by-interface migration plan rather than a like-for-like chassis substitution. Existing optics, patching, routing entitlements, and mounting accessories remain separate purchase decisions. Specify the required link media and replacement configuration before releasing the purchase order.
A multi-site standardization project that relies on chassis inventory tags must settle the RFID configuration at purchase. C9500-RFID selects the tag, while C9500-RFID-NONE omits it; the tag cannot be installed later. Specify the same inventory-tag decision across the purchase order before hardware configurations are finalized.
A lab or staging purchase for a network carrying jumbo frames needs end-to-end MTU validation before production acceptance. The switch supports frames of 9216 bytes, but adjacent equipment and selected interfaces must use compatible settings. Include the intended frame-size acceptance test in the staging requirements before the PO.
PoE-powered copper endpoint connections
C9500-48Y4C has fiber-facing network ports rather than powered RJ-45 access ports, so directly attached phones and access points require separate PoE access switching.
Uplinks faster than 100G
C9500-48Y4C uplinks stop at 100G. C9500X-28C8D adds eight 400G-capable ports, but changes the downlink layout to 28 native 40/100G ports.
StackWise Virtual with entry licensing
Network Essentials does not enable StackWise Virtual. Specify C9500-48Y4C-A with Network Advantage when the required configuration uses that network virtualization technology.

C9500-48Y4C identifies Catalyst 9500 hardware with 48 native 1/10/25G ports and four 40/100G uplinks: C9500 identifies the series, 48Y identifies the downlink configuration, and 4C identifies the uplinks. C9500-48Y4C-E adds Network Essentials; C9500-48Y4C-A adds Network Advantage. The unsuffixed number does not select a license tier.
C9500-48Y4C supports local management through its CLI and embedded WebUI, with Catalyst Center and Meraki dashboard options for centralized operation. Automation interfaces include NETCONF, RESTCONF, and gNMI using YANG models. Select the management arrangement together with the software release and subscription rather than assuming every path has identical entitlements.
Cisco has not announced an end-of-sale date for Catalyst 9500 C9500-48Y4C hardware. The discontinued C9500-40X configurations and C9500-48X-A and C9500-48X-E bundles reached end of sale on April 30, 2024; their retirement does not apply to this model. Hardware lifecycle and purchased service entitlements remain separate considerations.
C9500-48Y4C supports Cisco DNA Essentials or Advantage and Cisco Catalyst Essentials or Advantage subscriptions with three-year minimums, plus Cisco Networking Subscription with Cisco Switching Essentials or Cisco Switching Advantage and a 36-month minimum. The Cisco DNA path pairs with perpetual Network Essentials or Network Advantage. New orders require a Smart Account.
C9500-48Y4C with Network Essentials supports RIP, EIGRP Stub, OSPF up to 1000 routes, PBR, VRRP, and PIM Stub multicast up to 1000 routes. Network Advantage adds BGP, full EIGRP, IS-IS, and advanced multicast capabilities. The hardware route ceiling does not override the selected license's routing limits.
C9500-48Y4C supports C9K-PWR-650WAC-R, C9K-PWR-650WACL-R, and C9K-PWR-930WDC-R power supplies. A second internal supply enables redundant power operation and can be selected with the order or added later. Specify the required supply configuration explicitly; compatibility with multiple options does not identify the exact assembly included in a particular order.
C9500-48Y4C provides 48 SFP28 downlink cages supporting 1/10/25G operation and four QSFP28 uplink cages supporting 40/100G operation. The connection speed depends on the selected compatible transceiver and configuration. Specify optics for the intended link speed and media rather than treating the empty cages as complete optical connections.
C9500-48Y4C supports StackWise Virtual with Network Advantage, not with the baseline Network Essentials entitlement. StackWise Virtual is a network system virtualization capability rather than an additional installed uplink module. A purchase requiring that operating arrangement must include the appropriate network license instead of relying on hardware compatibility alone.
The Catalyst 9500 C9500-48Y4C occupies 1U and measures 43.9 mm high, 444.5 mm wide, and 457.2 mm deep. Its published weight with two power supplies and fans is 9.96 kg. Check usable rack depth, mounting hardware, and cable clearance against the complete order configuration before installation.
C9500-48Y4C replaces discontinued C9500-40X configurations and C9500-48X-A and C9500-48X-E bundles, all with an April 30, 2024 end-of-sale date. The configurations include C9500-40X, C9500-40X-10A, C9500-40X-10E, C9500-40X-1A, C9500-40X-1E, C9500-40X-2Q-A, C9500-40X-2Q-E, C9500-40X-A, C9500-40X-A-CCL, C9500-40X-A-FTTD, C9500-40X-A=, C9500-40X-E, C9500-40X-E=, C9500-40X-EDU, C9500-40X-P, and C9500-40X-P=.
C9500-48Y4C provides 48 native 1/10/25G downlink ports, while C9500-24Y4C provides 24; both retain four 40/100G uplinks. C9500-48Y4C suits an aggregation plan needing the larger connection count. C9500-24Y4C suits a smaller fiber connection requirement without changing to a different uplink speed class.
C9500-48Y4C is the hardware identifier without a selected network license suffix, whereas C9500-48Y4C-A specifies Network Advantage. Network Advantage adds advanced routing, segmentation, multicast, and StackWise Virtual. The base identifier suits a hardware-level inquiry; the suffixed form suits an order that must explicitly include the higher network entitlement.
C9500-48Y4C has four 40/100G uplinks, whereas C9500X-28C8D includes eight 40/100/200/400G-capable ports alongside 28 native 40/100G ports. C9500-48Y4C suits aggregation built around 25G connections and 100G uplinks. C9500X-28C8D suits a requirement for faster core-facing connections, with a materially different native port layout.
A Catalyst 9500 operating with perpetual network licensing can continue using its base license capabilities after a Cisco DNA or Cisco Catalyst add-on subscription expires. Renew the add-on to retain its functions, or deactivate it and reload the switch. Subscription expiration does not convert the perpetual network entitlement into a different tier.
ORM Systems offers C9500-48Y4C new sealed or certified refurbished, with up to a 3-year extended warranty for new units or up to 1 year for refurbished units. Every condition includes 30-day returns; terms apply. Cisco's separate Enhanced Limited Lifetime Warranty covers the original owner and is limited to five years after manufacturing discontinuance.
