Cisco Catalyst C9500-48Y4C-A
The Cisco Catalyst C9500-48Y4C-A is a high-performance 48-port 25Gbps fiber aggregation and core switch designed for enterprise campus, data center, and high-speed network environments. It provides 48 × 1/10/25Gbps SFP28 ports and 4 × 40/100Gbps QSFP28 ports, with the Cisco Network Advantage software package.
Description
The Cisco Catalyst C9500-48Y4C-A is an enterprise-grade, high-density switch from the Cisco Catalyst 9500 Series, designed for core, distribution, and aggregation-layer deployments where high-speed fiber connectivity and advanced Layer 3 capabilities are required.
The switch provides 48 × 1/10/25Gbps SFP28 ports, giving organizations flexible connectivity for high-speed servers, aggregation switches, access switches, and other fiber-based network infrastructure. Four additional 40/100Gbps QSFP28 ports provide high-bandwidth connectivity toward the network core or data center spine.
The “-A” suffix identifies the Network Advantage software package, providing advanced Layer 3 routing, enterprise security, automation, and network-management capabilities. The platform runs Cisco IOS XE, providing programmability and automation features for modern enterprise networks.
For high availability, the C9500-48Y4C-A supports StackWise Virtual, allowing compatible switches to operate as a single logical system while maintaining physical redundancy. This makes the platform well suited for resilient campus-core and data-center aggregation architectures.
