Switch Cisco Catalyst 9300 48-port data Ntw Ess

The Cisco Catalyst 9300 Series is a stackable enterprise switch platform designed for security, IoT, mobility and cloud. This managed L2/L3 switch model (C9300L-48P-4G-E) provides 48 Gigabit Ethernet (10/100/1000) RJ-45 ports, USB 2.0 connectivity and support for common IEEE networking standards. Built on the UADP 2.0 architecture and running Cisco IOS XE, the Catalyst 9300 delivers high stacking bandwidth, flexible uplinks, and an x86 CPU architecture that enables greater memory and the ability to host containers and third-party applications on the switch.

Advantages

The switch offers high-density 48-port Gigabit connectivity with support for PoE+ and Cisco UPOE when used with appropriate power modules, a large MAC address table (32,000 entries), and resilient stacking through Cisco StackWise and NSF/SSO for minimal downtime. It provides industry-leading stacking bandwidth (up to 480 Gbps), a modern programmable OS (IOS XE) for security and automation, and a power-efficient design with StackPower support.

Suitable for

• Enterprise access layer for wired user and device connectivity
• Converged networks integrating wired devices, Wi‑Fi 6 access points and IoT endpoints
• Environments requiring high-availability stacking and fast failover
• Deployments needing programmability and capacity for on-switch applications

How to use

Install the switch in a standard 19-inch rack using the supplied mounting brackets and connect power according to the product installation guide. Use the management Ethernet port, console port or USB for initial configuration and access Cisco IOS XE for CLI or API-based configuration. Connect access devices to the 48 Gigabit RJ-45 ports and configure VLANs, QoS and security policies as required for your network topology. For stacked deployments, interconnect switches with StackWise cables and configure stack parameters to enable single-instance management and NSF/SSO if high availability is required.

Recommendations

Place the switch in a controlled environment with adequate ventilation and stable power. Ensure firmware and IOS XE images are kept up to date, enable appropriate security features (802.1X, port security, ACLs), and plan power budgets if using PoE/PoE+ or UPOE to avoid overloading power supplies.
