APC AR3003 42U NetShelter Server Rack Cabinet

Overview

The APC AR3003 is a 42U enclosed server rack cabinet designed to support a wide range of rack‑mount IT equipment including servers, storage systems, network switches, and power distribution devices. It is deployed by infrastructure engineers, data center technicians, and network architects in environments such as enterprise server rooms, telecommunications closets, and edge compute cabinets where secure, standardized mounting and structured cabling are required. The cabinet’s design provides a rigid frame and comprehensive access points for serviceability, cable management, and airflow organization.

This cabinet supports the industry‑standard 19‑inch rack width and accommodates up to 42U of vertical equipment height, enabling deployment of moderately dense server and networking configurations without occupying excessive floor space. Adjustable front and rear mounting rails allow for equipment depth flexibility, supporting both shallow networking gear and deeper server chassis. Removable side panels, paired with front and rear doors, provide unobstructed access for installation, service, and cable routing.

The AR3003 enclosure is engineered to facilitate predictable airflow patterns around installed equipment. Ventilated doors and perforated panels improve convective cooling when integrated with data room air distribution systems or supplemental rack cooling solutions. Cable routing features within the cabinet help segregate power and data cabling, minimizing airflow obstructions and supporting organized deployments.

Typical use cases include housing virtualization hosts, SAN storage arrays, and aggregated networking gear in data closets or connecting infrastructure across multiple rack units in enterprise settings. The cabinet’s design supports long‑term installations where physical security, equipment organization, and service accessibility are essential.

This cabinet is not intended for portable or temporary installations; it is designed for fixed telecom and data room deployments where structured layouts and equipment protection are priorities.
