Middle Atlantic SNE30D-4548-P1 – 30" 45U 48" Digital Network Enclosure

Product Overview

The Middle Atlantic SNE30D-4548-P1 is a 30-inch wide, 45-rack-unit, 48-inch deep Digital Slim Network Enclosure configured for passive front-to-rear cooling — a ventilation strategy that uses equipment-generated airflow moving from the vented front door through to the 70% open split rear door without active fans. The 30-inch wide, 45U, 48-inch deep format provides the largest capacity in this SNE Digital lineup, suited for high-density IP network equipment, server deployments, and structured cabling infrastructure in data centers and technology rooms. The "D" Digital designation indicates cage-nut rack rails with 100 included 6mm cage nuts and rack screws for standard IT equipment mounting. The SNE30D-4548-P1 is UL/ETL listed and seismic certified for regulated commercial and government installations.

Product Description

The SNE30D-4548-P1 uses passive front-to-rear cooling, where the 70% open-area front door serves as the air inlet and the 70% open split rear door serves as the exhaust. This configuration relies on airflow generated by equipment fans and natural convection to move heat through the enclosure without a dedicated fan top or fan door. A solid top with brush cable pass-through provides clean cable entry from above while maintaining enclosure integrity. This passive cooling approach reduces noise, eliminates active fan maintenance, and suits environments where room-level cooling provides adequate heat removal.

At 30 inches wide and 48 inches deep, with 45 rack units of usable capacity, this is the largest enclosure in this Digital SNE series and is appropriate for dense server and network deployments requiring both horizontal and vertical expansion room. Two pairs of adjustable cage-nut rack rails are included, along with 100 6mm cage nuts and rack screws. Lever Lock compatibility accepts all vertical 21-inch accessories for tool-free integration of power distribution, cable management, and IP security components. The split flush-mount locking side panels secure access. Four casters and four leveling feet are included for installation mobility and stable final placement. The SNE30D-4548-P1 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 P1 uses passive front-to-rear cooling with 70% open front and rear doors and a solid top with brush cable pass-through. The P2 uses passive chimney cooling with a solid split rear door and chimney top with solid bottom and air diverter. The P1 is suited for environments where room-level front-to-rear airflow is the primary cooling method; the P2 is preferred where chimney convection is the design intent.

Q: Does the passive cooling configuration handle high-density server heat loads?

A: Passive front-to-rear cooling relies on equipment fans and natural convection, supported by room-level cooling infrastructure. For very high heat loads, active fan supplements or room cooling upgrades may be required. For installations where active enclosure cooling is needed, the SNE Hybrid (H) series with fan top or fan rear door configurations is the appropriate alternative.

Q: What rail hardware does the Digital configuration use?

A: Two pairs of adjustable cage-nut rack rails with 6mm cage-nut hardware, which is standard for IT servers, switches, 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 for IT equipment. For installations requiring 10-32 tapped rails for AV and analog gear, the Hybrid (H) series is the appropriate choice.

Q: What certifications does this enclosure carry?

A: The SNE30D-4548-P1 is UL/ETL listed and seismic certified for regulated commercial, government, and data center use.

Q: Is this enclosure compatible with Middle Atlantic Lever Lock accessories?

A: Yes. The enclosure accepts all Middle Atlantic Lever Lock vertical 21-inch accessories for tool-free installation of power distribution units, cable management, and small IP devices.

Q: What does the brush cable pass-through on the solid top provide?

A: The brush cable pass-through allows overhead cable runs to enter the enclosure cleanly from above while the brushes seal around cables to prevent dust ingress and maintain the enclosure's appearance.

Q: Where can I purchase the SNE30D-4548-P1?

A: Available from Creation Networks at creationnetworks.net.
