Description
Cisco Catalyst 9300 48-Port PoE+ Enterprise Switches (C9300-48P-A / C9300-48P-E)
Quick Buying Guide
-
Shared Enterprise Hardware: Both C9300-48P-A and C9300-48P-E share the same high-performance foundation: 48 ports of 10/100/1000 PoE+ connectivity, 480 Gbps StackWise-480 stacking bandwidth, and flexible modular uplink capability.
-
Network Advantage (C9300-48P-A): Best for advanced enterprise networks. Select this if you require full Layer 3 routing (BGP, EIGRP, IS-IS), SD-Access fabric integration, and comprehensive network segmentation (VXLAN/VRF).
-
Network Essentials (C9300-48P-E): High-value foundational access. Choose this for standard branch/campus deployments needing reliable Layer 2 switching and essential Layer 3 routing (Static, RIP, OSPF Stub) without the complexity of SD-Access.
-
Pro Tip: These models provide a default 437W PoE budget with the standard 715W AC power supply. For heavy PoE loads (e.g., 48 ports of full 30W PoE+), we recommend upgrading to the 1,100W AC power supply to maximize your power budget.
Overview
The Cisco Catalyst 9300-48P Series is the industry's premier stackable enterprise access switch, optimized for high-density PoE+ deployments. Built for a hybrid world where endpoints and applications are distributed, these switches utilize the modern Cisco IOS XE operating system, a multicore x86 CPU, and the programmable UADP 2.0 ASIC.
Whether you choose the Advantage or Essentials software license, the C9300-48P provides a secure, future-ready infrastructure. With support for flexible modular uplinks (1G, 10G, 25G, 40G), industry-leading Stacking bandwidth, and robust security features like AES-256 MACsec, these switches are engineered to handle the demands of IoT, mobility, and cloud-ready enterprise environments.
Core Highlights
-
48 Gigabit PoE+ Ports: High-density connectivity with 48 IEEE 802.3at PoE+ ports (up to 30W per port) to power your wireless APs, IP phones, and cameras.
-
Flexible Modular Uplinks: Dedicated hot-swappable network-module slot supports 1G, 10G, 25G, or 40G uplinks, allowing for simple, non-disruptive network upgrades.
-
High Performance: 256 Gbps switching capacity (up to 736 Gbps in a stack) with 190.47 Mpps wire-speed forwarding performance.
-
StackWise-480 Technology: Resilient stacking for up to 8 switches, providing 480 Gbps of stacking bandwidth and sub-50ms failover.
-
Enterprise-Grade Security: Line-rate AES-256 MACsec encryption, Secure Boot, and Trust Anchor Module (TAM) ensure a trustworthy and secure infrastructure.
-
Advanced Programmability: Native support for NETCONF, RESTCONF, YANG, and Python scripting enables zero-touch provisioning and deep network visibility.
Use Cases & Deployment Scenarios
-
High-Density Campus Access: Ideal for office environments, schools, or hospitals requiring large-scale PoE+ power delivery for wireless APs and IP endpoints.
-
SD-Access Fabric Edge (Advantage Model): Serves as a foundational building block for Cisco SD-Access, enabling automated, policy-based network virtualization.
-
Mission-Critical Branch Connectivity: Leverage StackWise-480 and cross-stack EtherChannel for "always-on" network availability in environments where downtime is not an option.
-
IoT Ecosystems: Centralize power and management for smart building sensors, digital signage, and environmental control systems.
