C9300L-48UXG-2Q Technical Specifications

The following table summarizes the principal hardware characteristics of the Cisco Catalyst C9300L-48UXG-2Q. Power availability, software entitlements, supported features, and ordering options should be confirmed against the exact product SKU and intended configuration before purchasing.

48-Port Connectivity for Modern Enterprise Networks

Port density is an important consideration when designing enterprise access networks. A switch with 48 access ports can connect a substantial number of endpoints within a single network closet, reducing the need to distribute basic connectivity across several smaller switches. The C9300L-48UXG-2Q provides this density while reserving higher-speed Multigigabit connectivity for devices that need more bandwidth than conventional Gigabit Ethernet can provide.

36 Gigabit Ethernet Ports for Everyday Devices

The 36 standard Gigabit Ethernet ports are designed for compatible endpoints operating at 10Mbps, 100Mbps, or 1Gbps. Typical applications include office computers, printers, conventional IP phones, access-control equipment, and other wired network devices. Actual throughput depends on the endpoint, negotiated link speed, network configuration, and available upstream capacity.

Organizations that need a more conventional access configuration can also compare the Cisco C9300L-48T-4X Switch, which offers 48 Gigabit Ethernet data ports and four fixed 10G uplinks, or the Cisco C9300L-48T-4G Switch, designed around fixed 1G uplinks.

12 Multigigabit Ports Supporting up to 10Gbps

The 12 Multigigabit ports distinguish the C9300L-48UXG-2Q from standard Gigabit access switches. These ports support multiple Ethernet speeds, enabling compatible devices to negotiate the highest supported rate permitted by the port, endpoint, and cabling installation.

Multigigabit access is particularly useful for enterprise wireless access points, high-performance workstations, and other devices that can generate traffic beyond the practical capacity of a single Gigabit Ethernet connection. It also provides flexibility when upgrading network endpoints over time, without requiring every connected device to use the same Ethernet speed.

For alternative port arrangements and uplink requirements, compare the Cisco C9300L-24UXG-4X Switch, the Cisco C9300L-24UXG-2Q Switch, and the Cisco C9300L-48UXG-4X Switch.

Why Multigigabit Ethernet Matters

Many modern wireless access points and enterprise endpoints can deliver aggregate traffic that exceeds what a 1Gbps wired connection can comfortably accommodate. Multigigabit Ethernet helps remove this access-link limitation when the endpoint supports higher speeds. It can also allow businesses to retain existing copper cabling when that cabling meets the requirements for the selected Ethernet rate, cable length, and installation environment.

Higher link speed does not automatically guarantee higher application throughput. The performance available to each device also depends on the access point or endpoint capability, upstream links, switching capacity, traffic patterns, and the wider network architecture.

Dual 40G QSFP+ Uplinks for High-Speed Network Aggregation

The C9300L-48UXG-2Q includes two fixed 40 Gigabit Ethernet QSFP+ uplink ports. These interfaces provide high-speed connectivity toward compatible aggregation or core switches and are especially relevant when numerous access devices generate substantial traffic.

For example, a campus network may connect the switch to an aggregation layer that serves several access closets. The 40G uplinks provide a faster upstream interface than the fixed 10G uplink configuration found on the C9300L-48UXG-4X. This distinction is an important part of model selection: the appropriate uplink depends on the existing network infrastructure, supported optics, link design, and required redundancy.

Before selecting transceivers or direct-attach cables, verify Cisco compatibility, QSFP+ interface requirements, fiber type, transmission distance, and the capabilities of the connected device. The presence of a 40G interface alone does not guarantee compatibility with every optical module or cable.

Businesses evaluating other enterprise uplink designs may also review the Cisco C9300X-12Y-E Switch, the Cisco C9300X-24Y-E Switch, and the Cisco Catalyst C9500-48Y4C-E Switch for alternative high-speed network architectures.

Cisco UPOE and Power Delivery

The C9300L-48UXG-2Q supports Cisco Universal Power over Ethernet (UPOE), allowing compatible powered devices to receive electrical power and network connectivity through supported Ethernet cabling. This can simplify installations by reducing the need for separate local power adapters for supported devices.

Powering Enterprise Endpoints

Depending on their individual power requirements and compatibility, connected equipment may include wireless access points, IP phones, collaboration devices, and other enterprise endpoints. UPOE capability is particularly valuable in environments where devices require more power than conventional PoE implementations can provide.

The switch has a specified 675W PoE budget with its default 1100W AC power supply. The actual power available to endpoints depends on the configured power supply, system operating conditions, and applicable hardware limitations. Network administrators should calculate the expected consumption of all connected devices before deployment, rather than assuming that every port can simultaneously deliver its maximum supported power.

For alternative PoE requirements, NexoGet also lists the Cisco C9300L-48PF-4X Switch, the Cisco C9300L-48P-4X Switch, and the Cisco C9300L-24P-4X Switch.

Planning the PoE Budget

A practical PoE deployment begins with an inventory of connected devices, their supported power classes, and their expected consumption. Include wireless access points, phones, cameras, and other powered endpoints where applicable. Leave sufficient capacity for future expansion and account for the power-supply configuration selected for the switch.

Organizations with a large number of powered endpoints should compare the total required wattage with the switch’s available PoE budget. They should also verify the per-port power capabilities and the maximum power supported by each connected device. These checks help avoid unexpected power limitations after installation.

StackWise-320 and Network Scalability

The Cisco Catalyst C9300L-48UXG-2Q supports StackWise-320 stacking when used with compatible equipment and the required stacking components. Stacking allows supported switches to operate together as a logical switching system, simplifying certain management and expansion tasks.

In an enterprise environment, stacking can be useful when a network closet requires additional access ports or when administrators want a more unified approach to managing compatible switches. The final design should account for the number of stack members, stacking cabling and hardware, software compatibility, and the supported stack configuration.

Stacking should not be confused with uplink aggregation. StackWise connects compatible switches into a supported stack architecture, while Ethernet uplinks connect the switch to other network devices. The two mechanisms serve different purposes and should be planned separately.

Network Management, Security, and Enterprise Deployment

The Catalyst 9300L platform is intended for managed enterprise networks, where administrators need to configure connectivity, monitor device behavior, and apply network policies. Available features depend on the software release, license tier, configuration, and deployment mode.

VLANs and Network Segmentation

Virtual LANs can separate groups of devices into logical networks. For example, an organization may separate employee computers, voice devices, wireless infrastructure, and guest access according to its network design. Proper VLAN configuration can help organize traffic and support security policies when combined with suitable routing, access controls, and monitoring.

Access Control and Network Visibility

Enterprise access switching can form part of a broader security architecture that includes authenticated access, traffic monitoring, segmentation, and centralized administration. The specific capabilities available on the C9300L-48UXG-2Q must be checked against the applicable Cisco software entitlement and configuration. Buyers should not assume that every feature available across the Catalyst 9300 family is included in every ordering variant.

Software Tier and SKU Verification

Product ordering codes may include suffixes that identify software entitlements, management options, or other ordering differences. Confirm whether the required configuration uses Network Essentials, Network Advantage, or another explicitly listed option before purchase. Also verify support requirements, subscription terms, and compatibility with the organization’s existing Cisco management environment.

For broader enterprise switching comparisons, consider the Cisco C9300-48H Switch, the Cisco C9300-24H Switch, and the Cisco C9300-48UXM Switch.

Cisco C9300L-48UXG-2Q vs. Related Catalyst Switches

Choosing the right enterprise switch requires comparing access-port speeds, uplink capacity, PoE requirements, and available expansion options. The following table highlights key differences among related models listed in the NexoGet catalog. Always confirm the exact product specification and ordering code before making a final decision.

When Should You Choose the C9300L-48UXG-2Q?

This model is a strong candidate when a deployment needs 48 copper access ports, a combination of standard Gigabit and higher-speed Multigigabit connections, UPOE, and two fixed 40G uplinks. It is particularly relevant where the network design calls for higher-speed aggregation but does not require the four fixed 10G uplinks of the C9300L-48UXG-4X.

If the majority of connected endpoints only need Gigabit Ethernet and the network does not require UPOE or 40G uplinks, a standard access model may offer a more appropriate specification. Compare the C9300L-48T-4G and C9300L-48P-4G for alternative data-only and PoE access configurations.

Installation and Network Planning Considerations

Before installing the Cisco C9300L-48UXG-2Q, verify rack space, cooling requirements, power availability, cable management, and the network closet’s environmental conditions. Confirm that the selected power supply and electrical installation are suitable for the intended configuration. Leave sufficient space for service access and follow Cisco’s hardware installation documentation.

For copper connectivity, choose cabling appropriate to the negotiated Ethernet rate and installation distance. A 10Gbps connection requires an end-to-end combination of compatible ports, cabling, and endpoint hardware. For the 40G uplinks, verify the supported QSFP+ modules or cables and ensure that the connected aggregation device supports the selected interface.

If stacking is required, check the compatible StackWise components, cabling, software versions, and supported topology before deployment. Document the port assignments, VLAN configuration, IP addressing, uplink connections, and PoE requirements. A structured deployment plan makes it easier to troubleshoot connectivity issues and expand the network later.
