Product Overview
Designed for scalable enterprise environments, the Cisco Catalyst C9300-48UN-1E is a 48-port managed Layer 3 switch offering multi-gigabit Ethernet up to 5Gbps per port and full UPOE support. With a 645W PoE budget and 48 x 100/1000/2.5G/5GBase-T RJ-45 UPOE ports, it enables a rich set of power-hungry devices such as wireless APs, VoIP devices, and smart IoT endpoints to operate seamlessly without the need for separate power sources. The device supports hot-plug redundant power supplies and operates in a 1U rack-mountable form factor, offering high-density deployment flexibility. With StackWise-480 technology, the C9300 delivers a redundant and unified management experience with stacking bandwidth of 480Gbps and switching capacity of 640Gbps, enhancing throughput and fault tolerance in mission-critical networks.
Advanced features such as Cisco Flexible NetFlow, full QoS capabilities, policy-based routing, and robust security implementations including 802.1X authentication, VLAN tagging, and Private VLAN support, make the switch ideal for complex network segmentation and traffic prioritization. It also supports a variety of routing protocols (OSPF, RIP, PIM-SM/SSM, VRRP, etc.), allowing dynamic and optimized multi-path forwarding. Managed via SNMP, NETCONF, RESTCONF, or CLI, and backed by a limited lifetime warranty with next-business-day replacement, the switch includes 8GB RAM and 16GB flash memory for reliable software operations. With a high MTBF of 198,647 hours and TAA compliance, it meets stringent federal and enterprise requirements for dependable infrastructure deployment.
