APC AR3104 4-Post Adjustable Server Rack

Overview

The APC AR3104 is a 4-post adjustable relay rack designed to support rackmount IT equipment such as servers, storage enclosures, network switches, and power distribution units. It is typically deployed by infrastructure engineers and data center technicians where open-frame rack support is required for accessible cable routing, cooling, and fast hardware deployment. The relay rack serves as the structural backbone for mounting equipment within telecommunications rooms, server closets, and data center aisles.

This rack is engineered to support equipment heights up to 12U and accommodate a range of chassis depths through adjustable rail spacing. The open design allows unobstructed airflow and simplifies access for installation, maintenance, and cable management. The unit can support deeper, heavier equipment when paired with appropriate equipment ear kits and strengthening accessories.

Constructed from welded steel with a durable finish, the AR3104 is suitable for installation on raised floors or hard surfaces. It includes hardware for securing the rack to the floor or to other racks, enabling system architects to create scalable multi-rack layouts linked by cable trays and power distribution solutions.

Typical deployment scenarios include mounting a small server and associated network switch in a telecommunications closet, organizing power distribution units and patch panels in a wiring room, or creating an accessible rack zone for test lab equipment where frequent reconfiguration is required. Because of its open architecture, this rack is not intended for environments requiring physical security, enclosures, or thermal containment.

This relay rack is not a UPS, power conditioner, or enclosed cabinet × its function is structural support for IT equipment and accessories.
