Middle Atlantic SNE24D-4548-P2 – 24" 45U 48" Digital Network Enclosure

Product Overview

The Middle Atlantic SNE24D-4548-P2 is a 24-inch wide, 45-rack-unit, 48-inch deep Digital Slim Network Enclosure configured for passive chimney cooling — a ventilation strategy suited for IP-based digital systems including network equipment, servers, and high-density structured cabling installations. The "D" Digital designation means this enclosure uses cage-nut rack rails (rather than 10-32 tapped rails) with 100 included 6mm cage nuts and rack screws, consistent with IT and data center equipment standards. The chimney cooling configuration — featuring a solid split rear door and chimney top with solid bottom and air diverter — channels heat upward through the enclosure for natural convection without active fans. This enclosure is UL/ETL listed and seismic certified, making it suitable for security systems integrators, IT infrastructure teams, and AV professionals deploying IP-based systems in data centers and server rooms.

Product Description

The SNE24D-4548-P2 is optimized for passive cooling environments where equipment generates heat that rises vertically through the enclosure. The chimney top and solid bottom with air diverter create a defined airflow chimney, guiding convective heat upward and out of the enclosure without requiring active fans. This reduces maintenance overhead and eliminates fan noise, which can be valuable in environments sensitive to acoustic output or where fan reliability is a concern.

At 45 rack units and 48 inches deep, this enclosure provides substantial capacity for dense IP network equipment, including switches, servers, patch panels, and IP security components. The 70% open-area front door, combined with the solid split rear door, supports controlled chimney airflow. Two pairs of adjustable cage-nut rack rails are included, along with 100 6mm cage nuts and rack screws for immediate equipment installation. Lever Lock compatibility accepts all vertical 21-inch Lever Lock accessories for tool-free integration of power distribution, cable management, and encoders. The split flush-mount locking side panels secure access while maintaining a finished enclosure appearance. Four casters and four leveling feet are included for installation mobility and final stabilization. The SNE24D-4548-P2 is available from Creation Networks at creationnetworks.net.

Frequently Asked Questions

Q: What is the difference between the P1 and P2 Digital configurations?

A: The P2 (SNE24D-4548-P2) uses passive chimney cooling with a solid split rear door and chimney top, channeling heat upward through convection. The P1 configuration uses passive front-to-back cooling with a 70% open rear door and solid top with brush cable pass-through, suitable for environments where front-to-rear airflow is preferred over chimney cooling.

Q: Why choose passive chimney cooling over active fan cooling?

A: Passive chimney cooling eliminates fan noise, reduces maintenance requirements, and removes a potential point of mechanical failure. It is well suited for IP network equipment that generates heat manageable through convection, particularly in data center environments where active cooling is provided at the room level.

Q: What rail hardware does the Digital configuration use?

A: The Digital configuration uses adjustable cage-nut rack rails (two pairs) with 6mm cage-nut hardware, which is the standard for IT and network equipment. One hundred 6mm cage nuts and rack screws are included.

Q: Does this enclosure include 10-32 tapped rails?

A: No. The Digital (D) configuration uses cage-nut rails with 6mm hardware, appropriate for IP network equipment and servers. For installations requiring 10-32 tapped rails, the Hybrid (H) series is the appropriate choice.

Q: What certifications does this enclosure carry?

A: The SNE24D-4548-P2 is UL/ETL listed and seismic certified for use in regulated commercial, government, and data center installations.

Q: Is this enclosure compatible with Lever Lock accessories?

A: Yes. The enclosure accepts all Middle Atlantic Lever Lock vertical 21-inch accessories for tool-free installation of power distribution, cable management, and small network devices such as encoders and access control equipment.

Q: Where can I purchase the SNE24D-4548-P2?

A: Available from Creation Networks at creationnetworks.net.
