Middle Atlantic SNE27D-4542-P1 – 27" 45U 42" Digital Enclosure

Product Overview

The Middle Atlantic SNE27D-4542-P1 is a 27-inch wide, 45U, 42-inch deep Slim Network Enclosure that bridges the gap between narrow 24-inch models and wide 30-inch cabinets, offering AV integrators and IT managers a mid-width option with full 45U capacity. The Digital enclosure design uses a chimney exhaust column for passive vertical heat removal, and the P1 rear door provides 70-percent open area for unobstructed front-to-rear airflow. Long-tail search terms: 27-inch wide 45U AV rack enclosure, mid-width passive digital server cabinet chimney cooling.

Product Description

The SNE27D-4542-P1 occupies 27 inches of width on the floor plan while providing 45U of rack space and 42 inches of interior depth, a combination that suits installations where both rack height and depth are important but a 30-inch wide footprint is not available. The 27-inch form factor is particularly useful in equipment rooms where multiple cabinets must be installed side by side within a fixed room width, and the narrower profile allows one additional cabinet to fit compared to 30-inch alternatives. The Digital (D) enclosure body is fully enclosed with an integrated chimney column that channels warm exhaust air upward, separating the hot exhaust from the cold supply aisle and reducing the risk of thermal recirculation. The P1 passive configuration relies on the internal fans of installed equipment to drive airflow through the 70-percent open rear door, keeping noise levels low and eliminating the maintenance associated with in-cabinet fan trays. At 42 inches of depth, the enclosure hosts full-depth servers, 2U switches, AV matrix switchers, and fiber distribution systems. Adjustable mounting rails, removable side panels for ganging, and included casters and leveling feet make the SNE27D-4542-P1 straightforward to stage and install. It is available from Creation Networks, an authorized Middle Atlantic distributor.

Frequently Asked Questions

Why choose a 27-inch wide cabinet instead of 24 or 30 inches?

The 27-inch width is a practical middle ground: it provides more interior clearance than 24-inch models for cable management, while allowing tighter multi-cabinet layouts than 30-inch alternatives when room width is limited.

What does P1 airflow mean for this model?

P1 means the rear door is 70 percent open, providing a low-resistance path for front-to-rear airflow driven by equipment-internal fans. No active fan trays are required inside the enclosure.

Is this enclosure compatible with overhead plenum cooling?

Yes. The chimney column exhausts heat vertically, making the SNE27D-4542-P1 directly compatible with overhead return-air plenum systems.

Can I gang multiple SNE27D units together?

Yes. Removable side panels allow adjacent SNE enclosures to be placed together to form a continuous multi-bay installation.

What depth of equipment fits in the 42-inch interior?

Standard full-depth 1U and 2U servers, enterprise switches, and most AV processors fit without modification in the 42-inch interior depth.
