Cisco Systems, Inc. C9300L-48P-4G-E 48-port PoE+ network switch

Cisco Catalyst 9300L enterprise switching platform

The Cisco Catalyst 9300L-48P-4G-E is a stackable Layer 3 switch built for enterprise networks that require security, IoT support, mobility and cloud integration. It provides 48 Gigabit Ethernet PoE+ ports and four SFP uplink interfaces for fibre connectivity. The platform uses an x86 CPU architecture with expanded memory to host containers and run third-party applications natively within the switch. It serves as a foundational building block for Software-Defined Access architectures.

Sustained high-density stacking performance

The switch delivers up to 480 Gbps of stacking bandwidth, maintaining throughput under continuous heavy load across the stack. Its uplink architecture supports flexible fibre connections without bottlenecks during prolonged data transfers. The PoE+ ports supply consistent power to connected devices such as Wi-Fi 6 access points and IP phones throughout extended operation. The hardware design ensures reliable forwarding capacity for demanding enterprise workloads over time.

Replaces legacy fixed-configuration access switches

This model upgrades environments still running older fixed-configuration switches that lack stacking bandwidth, native container support or high-density PoE+ capacity. The jump is justified when the network needs 48 powered ports, 480 Gbps stack throughput and the ability to run scripts or third-party applications directly on the switch. Buyers who require only basic unmanaged connectivity or fewer than 48 powered ports will not utilise the platform capabilities.
