Technical Specifications of Cisco C9300L-48UXG-4X

The following table summarizes the principal hardware characteristics of the Cisco Catalyst C9300L-48UXG-4X. Power delivery and software capabilities should be checked against the exact ordered SKU, power configuration, and licensing package.

Note: The stated 675 W is the documented PoE budget for the specified power configuration, not the switch’s total AC power consumption or the nominal wattage of its power supply. Consult the official hardware documentation for supported power configurations and environmental requirements.

Multigigabit Ethernet for High-Performance Networks

Wireless networking standards and enterprise applications continue to demand greater bandwidth from wired access infrastructure. Traditional Gigabit Ethernet connections can become a limitation when high-performance wireless access points, advanced workstations, or other high-throughput devices need more than 1 Gbps of wired connectivity.

The Cisco C9300L-48UXG-4X addresses this requirement with 12 multigigabit ports that support multiple Ethernet speeds up to 10 Gbps. This flexibility enables network administrators to select an appropriate connection speed for compatible devices while retaining conventional Gigabit Ethernet connectivity for other endpoints.

Benefits of Multigigabit Access

• Connect compatible wireless access points operating above 1 Gbps.
• Support bandwidth-intensive business applications and data transfers.
• Reduce the need to deploy separate switches for different access speeds.
• Support network upgrades while retaining existing Gigabit Ethernet endpoints.
• Provide greater flexibility when planning future network capacity.

Organizations can also compare the Cisco C9300L-24UXG-4X when a smaller number of access ports is sufficient. For deployments requiring a different high-speed uplink design, the Cisco C9300L-24UXG-2Q is another model worth evaluating.

Cisco UPOE for Enterprise Device Connectivity

The C9300L-48UXG-4X supports Cisco Universal Power over Ethernet (UPOE), allowing compatible powered devices to receive electrical power and network connectivity through Ethernet cabling. This can simplify deployments where installing separate electrical outlets for every endpoint would increase installation complexity.

Potential applications include compatible wireless access points, IP phones, collaboration devices, and other network-powered equipment. Actual power availability depends on the switch’s total PoE budget, port-level limits, power configuration, cable requirements, and the consumption of connected devices.

Power Planning Considerations

The documented 675 W PoE budget with the specified 1100 W AC power supply configuration provides a basis for planning connected equipment. Network administrators should calculate the expected consumption of all powered devices before deployment and retain sufficient capacity for future expansion.

For organizations that primarily require conventional PoE+ connectivity rather than UPOE and multigigabit access, consider the Cisco C9300L-48P-4X or Cisco C9300L-48PF-4X. The correct choice depends on endpoint power requirements, uplink needs, and the intended licensing configuration.

Four Fixed 10G SFP+ Uplinks

Uplink performance is an important consideration when selecting an access-layer switch. As more endpoints connect to a switch, its uplinks must provide sufficient capacity to carry traffic toward the distribution layer, data center, or other network destinations.

The Cisco Catalyst C9300L-48UXG-4X includes four fixed SFP+ uplink ports supporting 1 Gigabit or 10 Gigabit Ethernet operation with compatible interfaces. These uplinks provide flexibility for network designs that require high-speed aggregation and fiber connectivity.

Common Uplink Applications

• Connecting the access layer to an aggregation switch.
• Establishing 10G fiber links to compatible distribution infrastructure.
• Integrating the switch into enterprise campus networks.
• Supporting network segmentation and traffic management designs.
• Providing additional uplink options for planned network expansion.

Transceiver selection should account for the required transmission distance, fiber type, connector, wavelength, and compatibility with both connected devices. The four uplinks are fixed interfaces, so buyers should confirm that this design meets their requirements before purchasing.

For alternative uplink configurations, review the Cisco C9300L-48UXG-2Q, which uses two fixed 40G QSFP+ uplinks rather than four fixed 10G SFP+ uplinks.

StackWise-320 and Network Scalability

The Catalyst 9300L platform supports StackWise-320 technology, providing up to 320 Gbps of stacking bandwidth when configured with the required compatible hardware. A supported stack can simplify network administration by allowing compatible switches to operate as a coordinated switching system.

Stacking can be useful in enterprise environments that need to increase access-port capacity without managing every switch as an entirely separate unit. Depending on the network design and supported configuration, administrators can distribute endpoint connections across stack members while maintaining a consistent operational approach.

Enterprise Benefits of Stacking

• Expand access capacity by adding compatible stack members.
• Centralize selected management and operational tasks.
• Support structured network growth across departments and floors.
• Reduce complexity in suitable multi-switch access deployments.
• Plan capacity expansion around changing endpoint requirements.

The C9300L family supports stacking with compatible Catalyst 9300L and 9300LM models subject to hardware and licensing requirements. A stacking kit and compatible cables may be required and should be verified separately. Do not assume that every Catalyst 9300 or 9300X model can join a C9300L stack.

Typical Applications of the Cisco C9300L-48UXG-4X

1. Enterprise Campus Networks

Large offices and campus environments often require many Ethernet connections for employees, collaboration systems, printers, wireless access points, and business applications. The 48-port design gives network teams a substantial access layer, while the mix of multigigabit and Gigabit Ethernet ports accommodates devices with different bandwidth requirements.

2. High-Performance Wireless Infrastructure

Compatible high-performance wireless access points may require multigigabit wired connections to make better use of available wireless capacity. The 12 multigigabit interfaces provide options for deploying these access points without requiring every endpoint to use a 10G connection.

3. Corporate Voice and Collaboration

Enterprise networks often combine IP phones, workstations, conferencing devices, and wireless infrastructure. UPOE can simplify connectivity for compatible powered endpoints, while the switch’s standard Gigabit Ethernet ports can accommodate conventional network devices.

For Cisco collaboration hardware, NexoGet also lists the Cisco CP-8875 IP Phone, Cisco CP-8865 IP Phone, and Cisco DP-9861-K9 IP Phone. Verify the power and network requirements of each endpoint before integrating it into the network.

4. Educational Institutions

Universities, colleges, training centers, and schools can use a high-density managed switch to connect classrooms, offices, laboratories, wireless access points, and shared services. Multigigabit connectivity can be particularly valuable in areas where many users access bandwidth-intensive applications simultaneously.

5. Growing Business Networks

Businesses planning gradual infrastructure upgrades can benefit from a switch that supports both traditional Gigabit Ethernet and faster multigigabit connections. Existing 1G devices can remain connected while compatible endpoints are upgraded over time.

Cisco C9300L-48UXG-4X vs. Other Catalyst Switches

Management, Security, and Operational Considerations

Enterprise switching requires more than fast interfaces. Administrators must consider segmentation, access control, monitoring, configuration management, software maintenance, and the wider security architecture. Cisco Catalyst platforms provide enterprise switching capabilities, but the availability of particular features depends on the software release, license level, and deployment design.

Network Segmentation and Access Control

VLANs can help separate departments, guest access, voice endpoints, and infrastructure devices into logical network segments. Appropriate access-control policies and routing configurations can then restrict communication between those segments according to organizational requirements.

Monitoring and Troubleshooting

Network monitoring tools and supported management interfaces help IT teams identify connectivity issues, investigate performance bottlenecks, and maintain visibility across connected devices. Administrators should verify the supported management protocols and software features for the exact device configuration.

Software and Licensing

The ordering suffix matters when purchasing a Catalyst 9300L switch. Cisco product numbers may identify Network Essentials, Network Advantage, or Meraki management variants. The base model name alone should not be treated as confirmation of a specific license or management mode. Confirm the complete SKU and the included software entitlement before ordering.
