PRODUCT OVERVIEW

Cisco Catalyst C9300-48UN-A

High-Performance Multigigabit UPOE Enterprise Switching

The Cisco Catalyst C9300-48UN-A is a high-performance enterprise Layer 3 managed switch designed for organizations that require high-density Multigigabit connectivity, advanced UPOE power delivery, secure networking, and scalable infrastructure. Featuring 48 Multigigabit UPOE Ethernet ports, the switch is well suited for modern wireless access points, IP telephony, surveillance systems, IoT devices, digital signage, smart-building equipment, and other demanding enterprise endpoints.

Powered by Cisco IOS XE and equipped with the Network Advantage license, the C9300-48UN-A provides advanced Layer 2 and Layer 3 networking, routing, security, automation, and management capabilities. Its modular uplink architecture also allows organizations to select suitable uplink modules as bandwidth requirements evolve.

High-Speed Multigigabit Performance

The C9300-48UN-A is designed to support high-bandwidth enterprise applications with up to 480 Gbps switching capacity and approximately 356 Mpps forwarding performance. Multigigabit connectivity enables compatible devices to operate at higher speeds than conventional Gigabit Ethernet, making the switch suitable for high-density wireless networks, cloud applications, video collaboration, unified communications, and other bandwidth-intensive workloads.

Flexible Multigigabit Connectivity

The 48 Multigigabit Ethernet ports provide flexible connectivity for high-performance network devices. Supporting multiple Ethernet speeds allows organizations to deploy next-generation wireless access points and other high-bandwidth endpoints while making efficient use of existing structured cabling. This provides a practical migration path from traditional Gigabit Ethernet toward faster enterprise connectivity.

Advanced UPOE Power Delivery

With UPOE support of up to 60W per port, the Cisco Catalyst C9300-48UN-A can provide both network connectivity and high-power delivery through Ethernet cabling to compatible devices. This makes it an excellent platform for advanced wireless access points, IP phones, PTZ cameras, IoT equipment, digital signage, smart-building systems, and other power-intensive endpoints.

Modular Uplink Expansion

The modular uplink slot provides flexibility for expanding network connectivity according to deployment requirements. Organizations can select compatible uplink modules to establish higher-speed connections toward aggregation, distribution, or core network layers without replacing the complete access switch.

Scalable StackWise-480 Architecture

Cisco StackWise-480 technology allows compatible Catalyst 9300 switches to operate as a single logical system with up to 480 Gbps stacking bandwidth. This simplifies administration, improves resiliency, and enables organizations to scale their access-layer infrastructure as network requirements grow.

Enterprise-Class Network Security

The C9300-48UN-A incorporates enterprise security technologies including IEEE 802.1X authentication, Access Control Lists (ACLs), DHCP Snooping, Dynamic ARP Inspection, IP Source Guard, Secure Boot, and MACsec. These features help authenticate devices, control access to network resources, protect communications, and reduce security risks across enterprise environments.

Intelligent Network Management

Network administrators can manage the C9300-48UN-A through enterprise management technologies including Cisco Catalyst Center, CLI, Web UI, SNMP, SSH, NETCONF, and RESTCONF. These tools provide configuration, monitoring, automation, troubleshooting, and operational visibility across the network.

Reliable and Resilient Enterprise Infrastructure

The combination of high-density Multigigabit access, UPOE power delivery, modular uplink expansion, advanced Layer 3 functionality, stacking, and enterprise security makes the C9300-48UN-A a reliable platform for demanding access-layer deployments. It is designed to support organizations with increasing numbers of connected and powered devices.
