C9300X-48TX-A Cisco Catalyst 9300 Series Switch Overview
C9300X-48TX-A Cisco Catalyst 9300 Series Switch is a genuine campus and data-center switching product from Cisco, a leading enterprise networking vendor whose Catalyst, Nexus and ISR families power campus, data-center and branch networks worldwide. Belonging to the Cisco Catalyst 9300 Series family, the C9300X-48TX-A unit is built to the original factory specification, so it integrates with existing Cisco deployments predictably and behaves exactly as the platform documentation describes. In the network, it is suited to access-layer and edge deployments, where reliable wiring-closet operation and straightforward management are the priorities.
From a specification standpoint, it offers 48 ports for client, server or uplink connectivity; aggregate capacity of 640 Gbps. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Cisco hardware already running in the environment.
Typical deployments include access-layer deployments for user, phone and AP connectivity, distribution and core aggregation in campus networks, and top-of-rack and end-of-row switching in data centers. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “Catalyst 9300 48-port 10G/mGig with modular uplink, data only, Network Advantage”. This makes it a practical choice when original-spec hardware is required at a predictable cost.

C9300X-48TX-A - Cisco Series Notes
This listing is part of the Cisco enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Cisco Catalyst or Nexus switch is typically deployed in campus access, distribution, or data-center roles. It provides reliable Layer 2/3 switching for user, server and uplink connectivity, and integrates with Cisco DNA Center or traditional CLI-based management.
Deployment guidance: When planning this C9300X-48TX-A unit into a network, confirm the software image (IOS/IOS-XE/NX-OS) required, the power and cooling profile, and the upstream/downstream interface types that match your existing infrastructure. For a like-for-like refresh, match the feature set of the units already in service so management and automation behave consistently.
Our Cisco reconditioning process: Every pre-owned Cisco unit at LinkNewNet passes a documented reconditioning flow before dispatch - visual inspection, internal cleaning, firmware verification, port-by-port testing, and configuration reset to factory defaults. This ensures the unit you receive operates reliably and integrates cleanly with your existing Cisco management tools.
