Cisco Catalyst 4500 Series Line Card WS-X4516-10GE Overview
Cisco Catalyst 4500 Series Line Card WS-X4516-10GE is a genuine modular capacity expansion 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 4500 Series family, the WS-X4516-10GE 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.
From a specification standpoint, it offers 2 ports for client, server or uplink connectivity. 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 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 4500 Series Line Card WS-X4516-10GE V-10GE, 2x10GE (X2) and 4x1GE (SFP)”. This makes it a practical choice when original-spec hardware is required at a predictable cost.

WS-X4516-10GE - 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 WS-X4516-10GE 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.
