C9300-48P-E
Cisco Catalyst 9300 48-Port PoE+ Switch, Network Essentials
Tier-1 enterprise access switch featuring high-density 802.3at PoE+ power, modular high-speed uplink slots, wire-rate hardware encryption, and Cisco StackWise-480 architecture with 480 Gbps stacking throughput.
Engineered for High-Density Campus Switching
The Catalyst 9300 Series is Cisco’s premier lead stackable enterprise switching platform, engineered for security, IoT, mobility, and cloud convergence with unmatched PoE resilience.
High-Density Stacking Architecture
Powered by Cisco StackWise-480 technology, providing 480 Gbps of stacking bandwidth across up to 8 switches in a unified stack ring. Features deterministic sub-50ms stateful switchover (SSO) for mission-critical campus backbones.
Resilient PoE+ Power Infrastructure
Equipped with a default 715W AC Platinum power supply delivering 437W of dedicated PoE+ budget. Add a second hot-swappable modular PSU to scale up to 1440W of dynamic power allocation with Perpetual PoE and Fast PoE reboot resilience.
Cisco UADP 2.0 Silicon & Hardware Encryption
Programmable Unified Access Data Plane (UADP 2.0) ASIC enables line-rate Layer 2/3 classification, Flexible NetFlow (FNF), MACsec-128 link encryption, and micro-segmentation with Group-Based Policies (GBP).
Automated Deployment & Streaming Telemetry
Full open API ecosystem supporting NETCONF, RESTCONF, and YANG models. Supports model-driven streaming telemetry, on-box Python scripting, and zero-touch provisioning via Cisco Catalyst Center (DNA Center).
