APC ACDC2551

Overview

The APC ACDC2551 is a depth adapter designed for the NetShelter EcoAisle system, bridging cabinets with depths from 600 to 750 millimeters. It effectively seals the gap between racks to create a controlled airflow path, ensuring cold supply air reaches your servers while keeping hot exhaust air isolated. This adapter supports cabinets ranging from 42U to 48U in height and depths between 1070 and 1200 millimeters, making it a practical solution for improving thermal management in data centers and colocation environments.

Key features

• Active Flow Control technology adjusts airflow automatically based on equipment load, optimizing cooling efficiency and reducing energy consumption.
• Centralized return plenum directs hot air back to cooling units or external air handlers, helping maintain a stable environment and simplifying capacity planning.
• Optional Fire Safe System triggers ceiling panels to drop when heat or smoke is detected, allowing fire suppression systems to operate effectively.
• Integrated LED lighting with motion sensors illuminates the aisle only when needed, enhancing visibility while conserving power.
• Modular design enables quick installation on both 42U and 48U NetShelter SX cabinets, allowing easy scaling across rows or individual racks during maintenance.
• Lightweight construction at 18.7 kg facilitates manageable installation without heavy lifting equipment.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
