C9500-48Y4C-A is a fixed 1U Layer 3 core and aggregation switch with 48 native 1/10/25G SFP28 ports and four fixed 40/100G QSFP28 uplinks. The Network Advantage hardware PID places the Catalyst 9500 high-performance switch in the Cisco Catalyst 9500 Series for dense fiber aggregation, collapsed core, and routed distribution roles rather than copper access. The 48-port 25G core switch is non-PoE and has no modular uplink bay, so optics and cabling determine the attached fiber media. Managed Cisco IOS XE operation supports WebUI, CLI, Catalyst Center, and Meraki dashboard paths when the matching subscription is ordered. Its fixed uplinks suit routed aggregation toward distribution or data center handoffs while the SFP28 ports concentrate high-speed downstream links. C9500-48Y4C-E uses the same fixed port layout with Network Essentials instead of Network Advantage.
C9500-48Y4C-A price for new stock is $10,471.65, a 63.3% saving from the Cisco list price of $28,564.00. C9500-48Y4C-A refurb price is $7,875.00. C9500-48Y4C-A is in stock and available for next-day dispatch. (terms applied)

3200 Gbps switching capacity and 1 Bpps forwarding give the Catalyst 9500 48Y4C hardware a high-density fiber core profile. RIPv2, RIPng, OSPFv2, OSPFv3, EIGRP, EIGRPv6, IS-ISv4, BGPv4, BGPv6, PIM-SM, PIM-SSM, and PIM-BIDIR run under the Network Advantage tier. C9500-48Y4C-A uses the UADP 3.0 ASIC with 16 GB DRAM, 16 GB flash, 82000 MAC addresses, and up to 256000 IPv4 routes across direct and indirect entries. Cisco IOS XE management includes WebUI, CLI, Catalyst Center, and Meraki dashboard options. The platform supports StackWise Virtual, but it does not use removable C9500-NM-8X or C9500-NM-2Q uplink modules. A 650W C9K-PWR-650WAC-R supply is a supported AC option; C9K-PWR-650WACL-R and C9K-PWR-930WDC-R are also listed for the same chassis. 544W maximum draw and four C9K-T1-FANTRAY fan trays set the power and cooling envelope for rack planning.
C9500-48Y4C-A is available from ORM Systems new sealed or certified refurbished. Refurbished managed units are firmware verified, wiped to factory default, power-on and POST tested, checked for clean boot, every port links at rated speed, SFP and QSFP optics bay recognition is verified, and PSU and fan status are checked.

Deploy C9500-48Y4C-A as a compact campus core or collapsed-core switch when a chassis platform is unnecessary but high fiber density is required. The 48 1/10/25G SFP28 ports aggregate distribution or high-speed access links, while four 40/100G QSFP28 ports connect upstream, cross-core, or data center paths. Network Advantage supports advanced routing and segmentation features for resilient enterprise designs. This use case fits universities, hospitals, corporate campuses, and large public-sector sites refreshing older 10G cores while planning a gradual move toward 25G and 100G uplinks.
Use this switch to aggregate multiple access-layer stacks at the distribution layer, especially where access closets are moving beyond 10G uplinks. The SFP28 ports support 1G, 10G, and 25G optics, letting teams mix legacy links and newer high-speed uplinks during phased refreshes. The 100G-capable QSFP28 ports provide high-bandwidth paths to the campus core or services edge. With StackWise Virtual, paired switches can present a simplified logical design, helping reduce spanning-tree dependence and improving resiliency for buildings, floors, or branch campuses.
Place C9500-48Y4C-A at a data center interconnect, WAN edge aggregation, or service aggregation point where dense fiber and strong Layer 3 controls are needed in 1RU. Network Advantage is useful for BGP, IS-IS, HSRP, VRF, VXLAN, MPLS, and policy-driven segmentation requirements that appear in advanced enterprise networks. MACsec-256, telemetry, programmability, and Cisco IOS XE operations help teams secure and monitor high-value links. This use case is well matched to enterprises consolidating firewalls, routers, wireless controllers, or server-facing aggregation into a Catalyst 9500 design.
A campus core refresh with 10G aggregation links moving to 25G can use the 48 SFP28 downlinks and four 40/100G QSFP28 uplinks in one rack unit. Before the PO, specify the Advantage subscription term, optics for each fiber link, and whether the secondary PSU remains on the configuration.
A routed aggregation block that needs OSPFv2, OSPFv3, EIGRP, IS-ISv4, BGPv4, BGPv6, and multicast routing fits the Network Advantage tier on this PID. Size the route template against the 256000-route platform scale and confirm whether NAT or SD-Access templates are part of the build.
A dual-feed closet or data center handoff can use the 1+1 redundant PSU design with supported C9K-PWR-650WAC-R, C9K-PWR-650WACL-R, or C9K-PWR-930WDC-R supplies. Keep the secondary power supply line on the quote, choose the regional power cable, and match the airflow plan to the rack.
RJ-45 endpoint switching
C9500-48Y4C-A has 0 RJ-45 access ports; fixed connectivity is 48 SFP28 ports and four QSFP28 uplinks, so copper endpoint switching needs a different access platform.
400G uplinks
C9500-48Y4C-A tops out at four 40/100G QSFP28 uplinks; C9500X-28C8D-A moves to 8 x 40/100/200/400G ports alongside 28 x 40/100G ports.
Network Essentials standardization
C9500-48Y4C-A is the Network Advantage PID; C9500-48Y4C-E keeps the 48-port 25G hardware with Network Essentials for sites standardized on that tier.
Modular uplink bays
C9500-48Y4C-A has fixed uplinks, and the C9500-NM-8X or C9500-NM-2Q modules are not supported on C9500-48Y4C; do not plan expansion through network modules.
