Freestanding rack APC AR3380B2 42U Black Key lock Adjustable feet

The APC AR3380B2 is a freestanding 42U rack from the NetShelter SX family designed for organized equipment storage in data centres, server rooms and telecommunications closets. Finished in black with a secure key lock and adjustable feet for level installation, the enclosure supports higher-density computing and improved airflow management. Its all‑steel construction provides durable load capacity and the design includes front and rear doors with significant perforation to assist cooling of high‑power servers while allowing easy access for cabling and maintenance.

Advantages

The rack offers a combination of security, stability and serviceability: a keyed lock protects installed equipment, adjustable feet allow precise levelling on uneven floors, and the enclosure’s larger usable depth and robust load capacity support a wide range of IT hardware. Perforated doors and 270° door opening options simplify cable routing and improve airflow, and the steel construction ensures long service life with recyclable packaging that reduces environmental impact.

How to use

Position the freestanding rack on a firm, level surface and adjust the leveling feet until the enclosure is stable. Mount equipment into standard 19‑inch rack rails using appropriate cage nuts and mounting hardware, ensuring even weight distribution and compliance with rack unit spacing. Route power and network cabling through the designated cable access points and use cable management accessories to secure runs and maintain airflow. Lock the doors when physical access is not required and leave sufficient clearance for front and rear service access according to equipment manufacturer recommendations.

Usage recommendations

For efficient cooling and serviceability, install blanking panels in unused U spaces, use cable management to prevent obstruction of airflow, and follow recommended load distribution guidelines. Verify floor loading capacity before installing fully populated racks and consult APC accessories for compatible PDUs, cable organizers and airflow management solutions.
