C9500-24Q-A Description

Cisco Catalyst C9500-24Q-A—often called the Cisco 9500 24Q Advantage switch—is a 1-RU fixed-core platform that packs twenty-four wire-rate 40 GbE QSFP+ ports into a compact chassis. Each QSFP+ can split into 4 × 10 GbE, presenting up to 96 access links and a 1.92 Tbps non-blocking fabric. The DNA Advantage software tier unlocks SD-Access automation, Encrypted-Traffic Analytics and advanced routing, while hardware MACsec-256 encryption and Trust Anchor secure-boot enforce zero-trust design. Dual hot-swap 1600 W PSUs, N+1 modular fans and open IOS XE APIs (NETCONF, RESTCONF, gNMI) keep the C9500-24Q-A always-on and fully programmable for campus cores, data-centre leafs or metro aggregation.

non-blocking Layer 2/3 performance guarantees predictable latency for NVMe-oF storage, AI/ML clusters and UHD media workflows.

QSFP+ break-out flexibility

each port splits into 4 × 10 G, enabling up to 96 encrypted access links while preserving optics investments.

DNA Advantage software stack

unlocks SD-Access segmentation, Assurance analytics and ETA malware detection with no external controllers.

MACsec-256 & Trust Anchor

hardware 256-bit encryption plus secure-boot TPM protect data, keys and firmware for FIPS/GDPR compliance.

Hot-swap PSUs & N+1 fans

dual 1 600 W supplies and reversible airflow modules maintain uptime in high-density or temperature-challenged racks.

Applications Scenarios

Scientific HPC campus spine

links GPU/CPU compute islands at native 40 G, feeding parallel-file-system storage with loss-free, MACsec-encrypted traffic.

Large-scale Wi-Fi 7 controller core

aggregates up to 96 × 10 G AP controllers, then delivers 40 G uplinks to the WAN edge for seamless roaming.

OTT video streaming head-end

provides secure 40 G backbone between transcoding clusters and CDN cache arrays, handling bursty peak traffic without drops.
