Middle Atlantic SNE30D-4548-P2 – 45U Digital Security Network Enclosure

Product Overview

The Middle Atlantic SNE30D-4548-P2 is a fully configured 45U security network enclosure built for digital, IP-based security systems that combine high-density cabling, network switches, and servers in one rack. With a 30-inch width and 48-inch overall depth, this SNE Series digital enclosure gives integrators the extra lateral and rear space needed for structured cabling, vertical power distribution, and deep-chassis network equipment. Configured for passive chimney cooling, it manages equipment heat without fans, making it a dependable choice for security equipment rooms and commercial data closets where reliability matters most.

Product Description

The SNE Series Digital from Middle Atlantic was purpose-built for the realities of modern IP security deployments: dense Cat6 bundles, PoE switches, NVR servers, encoders, and access control hardware all living in the same rack. The SNE30D-4548-P2 arrives as a complete, pre-configured enclosure, so installers spend time loading equipment rather than assembling panels and doors on site. The P2 configuration is set up for passive chimney cooling, with a 70% open area vented front door drawing cool air across equipment, a solid split rear door, front air dams, and a solid bottom with air diverter channeling exhaust up and out through the chimney top. This thermal strategy removes heat without adding fan noise or moving parts to maintain.

Inside, two pairs of adjustable cage-nut rackrail with included 6mm hardware support standard 19-inch rack-mount equipment across all 45 rackspaces, while the 30-inch width leaves generous side channels for cable management and vertical accessories. The enclosure is Lever Lock compatible, accepting all 21-inch vertical Lever Lock accessories so small devices such as power supplies, encoders, and access control modules mount tool-free without consuming rackspaces. A pair of split flush-mount locking side panels secures the cabinet, and the unit ships with 100 6mm cage nuts and rack screws, four leveling feet, and four casters for positioning during installation. UL/ETL listing and seismic certification make this commercial-grade rack enclosure suitable for government, enterprise, and institutional projects with code-driven requirements.

Technical Specifications

Frequently Asked Questions

What is the SNE30D-4548-P2 designed for?
It is configured for digital, IP-based security systems — high-density cabling, network equipment, NVR servers, encoders, and access control hardware — and works equally well as a general network equipment enclosure.

How does the P2 passive cooling configuration work?
Cool air enters through the 70% open vented front door, passes across equipment, and warm exhaust rises through the chimney top. Front air dams and a solid bottom with air diverter keep airflow directed without any fans.

Does it accept standard 19-inch rack-mount equipment?
Yes. The two pairs of adjustable cage-nut rackrail support standard 19-inch equipment across all 45 rackspaces, and 100 6mm cage nuts and rack screws are included.

What are Lever Lock accessories and why do they matter?
Lever Lock is Middle Atlantic's tool-free mounting system. This enclosure accepts all 21-inch vertical Lever Lock accessories, letting you mount power supplies, encoders, and access control modules on the side walls without using up rackspaces.

Is this enclosure suitable for code-driven government or enterprise projects?
Yes. The SNE30D-4548-P2 is UL/ETL listed and seismic certified, which supports specification in government spaces and other regulated commercial facilities.

Can the enclosure be moved during installation?
Yes. Four casters are included for positioning during rack integration, along with four leveling feet for the final installed location.

Does Creation Networks support volume or project pricing?
Yes. As a commercial AV supplier, we support integrators and procurement teams with project-based quotes — contact us through creationnetworks.net for multi-rack deployments.
