C9400-LC-48UX - Cisco Catalyst 9400 Series Line Card Overview
C9400-LC-48UX - Cisco Catalyst 9400 Series Line Card is a genuine modular capacity expansion 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 9400 Series family, the C9400-LC-48UX 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 installed into a compatible chassis slot, where it works alongside the supervisor and line cards to extend the platform’s capabilities.
This unit follows the original factory specification for the Cisco Catalyst 9400 Series family, covering its intended role without compatibility surprises. Standard mounting, cabling and management practices apply, and it interoperates with surrounding hardware using the same procedures as other Cisco equipment already deployed in the network.
Typical deployments include adding ports and performance to existing chassis systems, modernizing legacy platforms with compatible line cards, and mixing copper, fiber and high-speed uplinks in one chassis. 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: “Cisco Catalyst 9400 Series 48Port UPOE w/ 24p mGig 24p RJ-45”. This makes it a practical choice when original-spec hardware is required at a predictable cost.

C9400-LC-48UX - Cisco Series Notes
This listing is part of the Cisco enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Cisco module/line card expands the capability of a chassis platform, adding interface density, forwarding capacity, or service features. It is installed in a matching chassis slot and managed as part of the parent platform.
Deployment guidance: When planning this C9400-LC-48UX 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.
