Middle Atlantic SNE27-CFD-42 SNE 27W FAN FD/RD 42U

Product Overview

The Middle Atlantic SNE27-CFD-42 is a 42U fan door assembly for SNE27 open-frame racks, providing combined front and rear fan-assisted cooling in a door-format retrofit kit. It converts a passive open-frame rack installation into an actively cooled configuration without requiring a full rack replacement. The assembly integrates fans directly into the door structure, directing airflow through the rack equipment bay. Available at creationnetworks.net.

Product Description

Open-frame racks provide good passive airflow but can face thermal challenges when equipment density increases or when racks are installed in spaces with limited ambient cooling. The SNE27-CFD-42 addresses this by adding active fan-assisted airflow through a door assembly that fits the SNE27 42U frame. The combined fan front and rear door design moves air directionally through the rack, improving heat extraction from thermally sensitive equipment such as amplifiers, video processing hardware, and dense networking gear. Installing fan doors is a cost-effective upgrade path compared to replacing an existing rack with an enclosed cabinet equipped with an active cooling system. The 42U height matches the SNE27 full-height frame, ensuring the fan doors cover the complete rack bay without gaps that would reduce airflow efficiency. Fan door assemblies from Middle Atlantic are designed for field installation on existing SNE27 racks using standard tools. The CFD designation indicates the combined front-and-rear door configuration, which provides both intake and exhaust management in a single accessory kit. This product is appropriate for integrators who have deployed SNE27 racks and are experiencing thermal issues as equipment density increases over time, or for new installations in warm equipment rooms where passive cooling is insufficient.

Key Features

• 42U fan door assembly — Covers the full height of the SNE27 42U frame for complete airflow management.
• Combined front and rear fan doors — Provides both intake and exhaust airflow management in a single kit.
• Active cooling retrofit — Adds fan-assisted airflow to existing open-frame SNE27 racks without rack replacement.
• Field-installable — Designed for installation on deployed SNE27 frames using standard tools.
• Directional airflow — Improves heat extraction from high-density equipment bays.
• SNE27-specific fit — Engineered for the SNE27 frame dimensions; no modification required.

Typical Applications

• SNE27 open-frame racks with increasing equipment density causing thermal issues
• Equipment rooms with inadequate ambient cooling where rack-level active cooling is needed
• New installations in warm or thermally challenging spaces where passive airflow is insufficient
• AV server rooms and networking closets with high-wattage equipment concentrations
• Broadcast and production facilities with dense rack deployments generating significant heat

Frequently Asked Questions

Q: Will the SNE27-CFD-42 work on an SNE24 or other SNE frame height?

A: No. The CFD-42 is sized for the 42U SNE27 frame. Different SNE frame heights require the corresponding door assembly. Contact Creation Networks for the correct part number for other SNE frame sizes.

Q: Does this fan door assembly require a separate power connection?

A: Yes. The integrated fans require a power source. The assembly typically uses a standard IEC power connection; confirm wiring requirements with the installation documentation included with the product.

Q: Can this be installed with equipment already loaded in the rack?

A: Installation is possible with equipment in place, though access may be limited. Middle Atlantic recommends reviewing the installation guide before attempting a retrofit on a fully loaded rack.
