Cisco Catalyst 9300L-48P-4X-A Switch

The Cisco Catalyst 9300L-48P-4X-A Switch is a premier enterprise-grade networking solution engineered to meet the evolving demands of modern organizations. This switch combines robust security, seamless mobility, and cloud-ready management in a compact yet scalable platform. Built on Cisco’s trusted IOS XE foundation, it delivers reliable performance, intelligent automation, and resilient connectivity for campus, edge, and distribution networks. With high-density PoE, four high-speed uplinks, and advanced security features, the Catalyst 9300L-48P-4X-A is designed to simplify deployment, accelerate innovation, and protect your network from evolving threats while providing a solid foundation for future growth.

• Powerful PoE+ capabilities for edge devices: The 48 PoE+ ports power a wide range of devices—from IP phones and wireless access points to security cameras—without requiring separate power infrastructure. This enables streamlined campus deployments, reduces cable clutter, and supports future device needs with flexible power budgeting and energy efficiency features.
• Four 10-Gigabit uplinks for scalable connectivity: Four 10G uplinks (SFP+/10GBASE) provide high-bandwidth, low-latency links to your core, data center, or distribution layers. This uplink capacity supports demanding applications, virtualization, and fast, reliable failover in resilient network architectures.
• Advanced security and policy enforcement: Built-in security features include 802.1X authentication, dynamic ARP inspection, DHCP snooping, ACL-based segmentation, and trusted access controls. These capabilities help protect network borders, enforce policies at the edge, and simplify compliance across devices and users.
• Smart management, programmability, and automation: Running Cisco IOS XE, the Catalyst 9300L-48P-4X-A supports modern automation and integration with Cisco DNA Center, NETCONF/RESTCONF, and open APIs. Centralized management accelerates firmware updates, configuration rollouts, and policy deployment across single switches or larger campus deployments, reducing operational overhead.
• Reliable design for campus and edge deployments: Engineered for consistent performance in dynamic environments, the 9300L-48P-4X-A supports stacking and high-availability considerations to minimize downtime. Its scalable architecture and efficient power usage make it a strong choice for growing networks that require dependable performance at the edge and in distribution.
