Ideal Use Cases
Campus Core Switching
The C9500-48Y4C-A is purpose-built as a fixed core and aggregation platform for enterprise campuses, delivering non-blocking 25G density and 100G uplinks to handle high-volume east-west and north-south traffic.
Distribution Layer Aggregation
With 48 SFP28 ports capable of 1/10/25G, this switch efficiently aggregates traffic from multiple access-layer switches, making it ideal for high-density campus distribution deployments transitioning beyond 10G.
Data Center Top-of-Rack or Aggregation
The combination of 3.2 Tbps switching capacity, 100G QSFP28 uplinks, and rich Layer 3 routing features makes the C9500-48Y4C-A well-suited for small-to-mid data center aggregation or server-facing aggregation tiers.
SD-Access Fabric Border or Control Node
Running Cisco IOS XE with Network Advantage, this switch supports Cisco SD-Access segmentation and policy enforcement, qualifying it as a fabric border or control node within a Cisco DNA-based architecture.
Enterprise Network Modernization
Organizations upgrading from legacy 1G or 10G core infrastructure can deploy the C9500-48Y4C-A as a scalable step to 25G and 100G without a full greenfield rebuild, leveraging StackWise Virtual for system-level redundancy.
High-Availability Core with Redundant Power
The platform supports dual 1+1 platinum-rated, field-replaceable power supplies and redundant fans, making it appropriate for mission-critical network layers where uptime and serviceability are non-negotiable.

The four uplink ports on the C9500-48Y4C-A support both 40 Gigabit Ethernet (QSFP+) and 100 Gigabit Ethernet (QSFP28) transceivers, giving you flexibility to connect to existing 40G infrastructure or upgrade to 100G uplinks as your network evolves. Transceiver modules are not included and must be sourced separately.
Yes. The C9500-48Y4C-A supports Cisco StackWise Virtual, which allows two physical switches to operate as a single logical system for improved redundancy, simplified management, and scaled system bandwidth. StackWise Virtual requires compatible IOS XE software and proper cabling between the two units.
