The Cisco Catalyst C9300L-48T-4X-E is built on Cisco’s Unified Access Data Plane (UADP) 2.0 ASIC, delivering wire-speed forwarding and advanced programmability. The switch chassis supports a fixed configuration with 48 RJ-45 10/100/1000 Mbps ports and 4 fixed 10 Gigabit SFP+ uplink ports. The device supports stacking via Cisco StackWise-160 technology, enabling up to eight switches to operate as a single logical unit with a combined bandwidth of 160 Gbps.
Key hardware specifications include:
The 48 fixed ports support 10/100/1000 Mbps speeds with auto-negotiation and full PoE+ (802.3at) support, enabling connectivity for IP phones, wireless access points, and other powered devices. The four fixed 10 Gigabit SFP+ uplink ports provide high-bandwidth aggregation capabilities, supporting both fiber and copper transceivers for flexible deployment scenarios.
The C9300L-48T-4X-E ships with the Cisco IOS XE Software, a modular operating system that supports advanced networking features, programmability, and security. The “E” license (Enterprise Services) enables:
The switch is designed for standard 19-inch rack mounting with a 1RU form factor. It operates within a temperature range of 0°C to 45°C and supports front-to-back airflow for efficient cooling in data center and wiring closet environments.
The C9300L-48T-4X-E provides 48 Gigabit Ethernet ports with full PoE+ support, delivering up to 30W per port. This capability is critical for powering a wide range of endpoint devices such as IP phones, wireless access points, security cameras, and IoT sensors without requiring separate power infrastructure. The high PoE budget of up to 740W ensures simultaneous powering of multiple devices with headroom for future expansion.
