Cisco Catalyst 9300L Switch for Enterprise Networks

The Cisco Catalyst 9300L-48P-4G-A is a managed, rack-mountable network switch designed for enterprise environments. It provides forty-eight ports with Power over Ethernet capability to support devices such as wireless access points and IP phones. The switch runs on an x86 CPU architecture with expanded memory to host containers and run third-party applications natively.

Suits IT Teams Building Stackable Access Layers

This switch fits organisations deploying Software-Defined Access architectures that require high-density stacking bandwidth up to 480 Gbps. It supports Cisco StackWise technology with nonstop forwarding and Stateful Switchover for sub-50-ms resilience. Buyers who need unmanaged operation or desktop form factors should evaluate other options.

Primary Port Speed Defines Uplink Compatibility

The primary port speed is rated for 1000Base-X and 1000Base-T connectivity. This specification determines which uplink modules and cabling infrastructure can be used with the platform. Verify that your existing fibre and copper links match these speed ratings before purchase.

Questions about this item

How do I install the C9300L-48P-4G-A in a rack and what step is often missed?

Mount the 15.50 lb chassis, insert the three field-replaceable fans and the included power supply, then connect cables; the step often missed is fully seating all three fans before first power-on.

Which components of the C9300L-48P-4G-A will need replacement over time?

The three field-replaceable fans are the primary maintenance items; they can be swapped individually without removing the switch from the rack.

What is the stacking bandwidth limit that appears first under sustained load on the C9300L-48P-4G-A?

The stack interconnect tops out at 480 Gbps, so sustained cross-stack traffic will hit that ceiling before individual 1000Base-T ports saturate.
