Cisco Catalyst 9300-L Series Switches C9300L-48PF-4X-A Overview
Cisco Catalyst 9300-L Series Switches C9300L-48PF-4X-A is a genuine campus and data-center switching product from Cisco, a global name in networking whose platforms are used by enterprises, service providers and data-center operators alike. Belonging to the Cisco Catalyst 9300-L Series family, the C9300L-48PF-4X-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, aggregate capacity of 392 Gbps; packet forwarding up to 291.66 Mpps; 675 W PoE budget. 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 fixed uplinks Full PoE+, 4X10G uplinks, Network Advantage”. This makes it a practical choice when original-spec hardware is required at a predictable cost.

C9300L-48PF-4X-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 C9300L-48PF-4X-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.
