Managed L2/L3 Network Switch Cisco C9300L-48T-4X-A

The Cisco C9300L-48T-4X-A is a managed L2/L3 network switch from the Catalyst 9300 Series, offering 48 Gigabit Ethernet (10/100/1000) RJ-45 ports and four 10GbE uplink ports. Built on the Catalyst 9300 platform, it supports high-density enterprise access, software-defined access (SD-Access) foundations, and an x86-based architecture that enables advanced programmability and future expandability.

Advantages

This managed switch provides high port density and reliable performance with support for Layer 2 and Layer 3 features, a 32,000-entry MAC address table, and compliance with common IEEE networking standards. It supports resilient stackable operation using Cisco StackWise and high-density power delivery via Cisco StackPower and UPOE/PoE+ capabilities on compatible models. Cisco IOS XE delivers modern OS programmability, security features, and IoT convergence options.

Suitable for

• Enterprise access-layer deployments in campus and branch networks
• Data closets and rack-mounted installations requiring 48-port Gigabit connectivity
• Environments needing managed L2/L3 switching with SD-Access integration

How to use

Install the switch in a standard 19-inch rack using rack-mount brackets. Connect access devices to the 48 Gigabit RJ-45 ports and attach uplink modules or SFP+ transceivers to the 10GbE uplink ports as required. Configure basic switch settings and VLANs via the Cisco IOS XE command-line interface (CLI) or a supported management platform. Use StackWise to create a resilient stack when deploying multiple Catalyst 9300 switches, and enable required PoE/UPOE features if powering connected devices.

Recommendations

For optimal performance, place the switch in a temperature-controlled rack, keep firmware updated to the latest Cisco IOS XE release supported for C9300L-48T-4X-A, and follow Cisco guidance for stacking and power configuration. Plan VLANs, QoS, and security policies before deployment to ensure consistent access-layer behavior.
