The Cisco Catalyst C9300X-48TX is a modular enterprise switch developed for high-performance wired access. Its 48 multigigabit copper ports allow organizations to connect a large number of network devices while supporting faster Ethernet speeds than conventional Gigabit-only access switches.

As business applications, wireless infrastructure, collaboration systems, and data-intensive workflows continue to evolve, network access infrastructure must provide sufficient bandwidth without creating unnecessary complexity. The C9300X-48TX addresses this requirement by combining high-density multigigabit connectivity with modular uplink options and enterprise switching capabilities.

The switch is part of the Cisco Catalyst C9300X-48HX product family. Although these models share the Catalyst 9300X platform, they serve different requirements. The C9300X-48TX is designed for data connectivity, while the C9300X-48HX adds Cisco UPOE+ support for compatible powered devices.

Designed for Modern Enterprise Networks

Organizations increasingly need more than standard Gigabit Ethernet connectivity. High-speed wireless access points, workstation upgrades, large file transfers, virtualized environments, and demanding business applications can place additional pressure on network access infrastructure.

The Cisco C9300X-48TX provides a multigigabit access platform that can support these requirements when the connected devices, cabling, uplinks, and overall network design are compatible. Its modular architecture also gives network administrators flexibility when selecting upstream connectivity for distribution or core network layers.

Data-Only Switching Without Integrated PoE

One of the most important characteristics of the C9300X-48TX is its data-only port configuration. It should not be selected as a replacement for a PoE switch when connected devices require power from Ethernet ports.

For installations requiring powered access points, compatible phones, or other PoE devices, compare it with the Cisco Catalyst C9300X-48HX or review the PoE-capable Cisco Catalyst C9200-48P-E. The appropriate choice depends on port speed, power requirements, uplink design, software licensing, and the complete deployment plan.

Cisco C9300X-48TX Technical Specifications

The following table summarizes key specifications of the Cisco Catalyst C9300X-48TX. Confirm the complete product SKU and hardware configuration before ordering because licensing, power supplies, network modules, and included accessories can vary.

Important: These specifications describe the C9300X-48TX platform and its documented configuration. Shipping dimensions, gross package weight, included network modules, power cords, software licenses, and other accessories must be verified against the actual item being supplied.

48-Port 10G Multigigabit Ethernet Connectivity

The C9300X-48TX provides 48 copper Ethernet ports with support for multiple link speeds. This allows network administrators to connect compatible devices at the speed they support without requiring every endpoint to operate at the same Ethernet rate.

Flexible Connection Speeds

Supported link rates include 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps. This multigigabit capability is useful when organizations upgrade selected parts of their infrastructure over time. Existing Gigabit Ethernet devices can continue to connect while compatible higher-speed endpoints take advantage of faster links.

Actual throughput depends on the connected equipment, network cabling, configuration, traffic patterns, and upstream capacity. A 10 Gbps port does not guarantee that an application will consistently achieve 10 Gbps of usable throughput.

High-Density Copper Access

With 48 multigigabit ports in a single switch, the C9300X-48TX can consolidate many wired connections into a rack-mounted enterprise access platform. This can simplify network planning for offices, campuses, and other locations where multiple high-speed endpoints must be connected in a centralized wiring environment.

Organizations evaluating lower-speed or different port-count alternatives can also review the Cisco Catalyst C9200-48T-E, the Cisco Catalyst C9200L-48T-4X-E, and the Cisco Catalyst C9200L-48T-4G.

Modular Uplinks and Network Expansion

The Cisco Catalyst C9300X-48TX uses a modular uplink design. This enables compatible network modules to be selected according to the requirements of the upstream network, helping organizations align access-layer connectivity with their distribution or core architecture.

Selecting the Right Uplink Module

Uplink selection should be based on required interface speeds, fiber or copper connectivity, optical transceiver compatibility, link aggregation plans, and the capabilities of the upstream switch. Supported options vary by network module and configuration, so the module must be checked against Cisco compatibility documentation before purchase.

For compatible expansion hardware, see the Cisco C9200-NM-2Y, Cisco C9200-NM-2Q, Cisco C9200-NM-4G, and Cisco C9200-NM-4X product pages for related Cisco network-module options. These are related catalog products, not a guarantee that every module listed is compatible with the C9300X-48TX.

Planning Uplink Bandwidth

When connecting a 48-port multigigabit switch to the rest of an enterprise network, uplink capacity is an important design consideration. Network architects should estimate aggregate traffic, identify oversubscription expectations, and select uplink interfaces that match the distribution or core layer.

A well-planned uplink design helps reduce congestion and provides room for future growth. The right choice depends on the number of active endpoints, traffic demand, network topology, redundancy requirements, and supported hardware options.

Cisco StackWise-1T and Enterprise Scalability

The C9300X-48TX supports Cisco StackWise-1T technology in supported configurations. Stacking allows compatible switches to operate as a coordinated system for network management and expansion. It can be useful for organizations that need additional port capacity while maintaining a consistent switching architecture.

Benefits of a Stackable Switching Platform

• Capacity Expansion: Compatible switches can be combined to increase the available access-port count.
• Centralized Administration: Supported stack configurations can simplify operational management.
• High-Bandwidth Stacking: StackWise-1T provides the platform’s specified stacking bandwidth when used in a supported configuration.
• Network Growth: Organizations can plan capacity additions around changing endpoint and traffic requirements.

Stacking is not a substitute for network design. The number of switches, supported stack members, software versions, cabling, redundancy strategy, and compatibility requirements should be verified before deployment.

Cisco IOS XE and Enterprise Network Operations

The Cisco Catalyst C9300X-48TX runs Cisco IOS XE, an enterprise networking software platform. Available features depend on the selected license, software release, configuration, and any applicable hardware requirements.

Network Segmentation and Traffic Management

Enterprise switching deployments commonly use VLANs, access controls, quality-of-service policies, and routing features to organize network traffic. The C9300X-48TX can be considered for these types of environments when the required capabilities are supported by the selected software configuration.

Security and Operational Planning

Network security involves more than choosing a switch. Administrators should plan access policies, device authentication, management access, software maintenance, monitoring, and configuration backups. Cisco’s documented platform capabilities and the selected software license should be reviewed to determine which features are available for a specific installation.
