C9300X-12Y-A Description

  The Cisco Catalyst C9300X-12Y-A is a high-density, data-only fiber access switch engineered for campus and data-center edge environments demanding ultra-high throughput, advanced routing, and robust security. It offers 12 multi-rate SFP28 fiber ports capable of 25 Gbps, 10 Gbps, or 1 Gbps, enabling seamless migration to higher-speed optics as network demands escalate. Four modular uplink slots accommodate any combination of C9300X network modules—such as the NM-8Y (8×25 G/10 G/1 G SFP), NM-2C (2×100 G/40 G QSFP), or NM-4C (4×100 G/40 G QSFP)—providing flexible aggregation or core connectivity without forklift upgrades.
