Quick Buying Guide
-
Shared High-Performance Hardware: Both the C9300-48T-A and C9300-48T-E share the exact same enterprise-grade hardware base: 48 Gigabit RJ-45 data ports, 480 Gbps StackWise-480 stacking bandwidth, and flexible modular uplink slots.
-
Network Advantage (C9300-48T-A): Built for advanced networking. Select this model if your enterprise architecture requires complex routing protocols (BGP, EIGRP, IS-IS), network virtualization (VXLAN, VRF), or Cisco SD-Access automation.
-
Network Essentials (C9300-48T-E): High-value foundational access. The ideal choice for traditional campus or branch environments that require robust Layer 2 switching and essential Layer 3 routing (RIP, OSPF Stub) without the need for full SD-Access capabilities.
-
Pro Tip: Since both of these models are Data-Only (no PoE support), they are highly cost-effective and perfect for high-density workstation environments, server aggregation, or trading floors. If you need to power Wi-Fi 6 access points or IP cameras, you should consider the C9300-48P series instead.
Product Overview
The Cisco Catalyst 9300-48T Series is Cisco's premier stackable enterprise access switching platform, purpose-built for high-density data connectivity. As dedicated data-only members of the Catalyst 9000 family, they omit PoE circuitry to maximize energy efficiency while delivering wire-speed, non-blocking forwarding performance for your most demanding campus traffic.
Running on the modern Cisco IOS XE operating system and powered by a multicore x86 CPU and Cisco's programmable UADP 2.0 ASIC, the C9300-48T series supports containerized application hosting natively. Whether equipped with the Advantage or Essentials license, these switches provide unmatched resilience via StackWise-480 technology and future-proof flexibility with modular uplinks ranging from 1G to 40G.
Core Highlights
-
48 Gigabit Data Ports: 48 auto-sensing 10/100/1000 Mbps RJ-45 ports designed purely for high-speed data throughput.
-
Flexible Modular Uplinks: A dedicated hot-swappable uplink slot supports 1G (SFP), 10G (SFP+), 25G (SFP28), and 40G (QSFP+) network modules to scale with your bandwidth requirements.
-
StackWise-480 Resiliency: Stack up to 8 switches into a single logical entity, delivering an industry-leading 480 Gbps of stacking bandwidth with sub-50ms failover protection.
-
Enterprise-Grade Security: Native support for line-rate AES-256 MACsec encryption, hardware-anchored Secure Boot, and Trust Anchor Module (TAM) to defend against sophisticated network threats.
-
Programmability & Telemetry: Built-in support for NETCONF/RESTCONF, gNMI, streaming telemetry, and Python scripting, enabling zero-touch automation and seamless integration with Cisco Catalyst Center (formerly DNA Center).
-
Sustainable Design: Features IEEE 802.3az Energy-Efficient Ethernet and low-power fan management to help meet corporate sustainability goals.
Use Cases & Deployment Scenarios
-
High-Density Enterprise Office: Provides highly reliable, wire-speed data connectivity for hundreds of employee workstations, printers, and standard Ethernet peripherals.
-
Server Aggregation (ToR): Serves as an efficient Top-of-Rack data switch for server rooms and storage networks where PoE overhead is unnecessary.
-
SD-Access Fabric Edge (Advantage Model): Acts as a foundational boundary node for Cisco SD-Access architecture, enabling automated, policy-driven micro-segmentation across the network.
-
Campus Core & Aggregation: Leverage StackWise-480 to create high-bandwidth, resilient logical switches in large branch offices or traditional campus access layers.
