Middle Atlantic SNE24D-4542-P2 – 45U Digital Security Network Enclosure

Product Overview

The Middle Atlantic SNE24D-4542-P2 is a 45U digital security network enclosure configured for IP-based security systems built around high-density cabling, network equipment, and servers. With a 24-inch width and 42-inch overall depth, it provides the clearance modern network hardware and server-depth equipment require in commercial deployments. The P2 configuration uses passive chimney cooling, making it well suited to data centers and equipment rooms where fan noise and powered ventilation are unwanted.

Product Description

As part of Middle Atlantic's SNE Series Digital lineup, the SNE24D-4542-P2 arrives fully configured for digital security and network installations, reducing on-site assembly time for integrators. Two pairs of adjustable cage-nut rackrail ship with the enclosure, along with 100 6mm cage nuts and rack screws, so switches, servers, network video recorders, and patch panels can be mounted immediately without sourcing separate hardware. The 42-inch overall depth accommodates deep server chassis plus rear cable service loops, a frequent constraint in IP video surveillance head ends.

Thermal management is entirely passive. Cool air enters through the 70 percent open vented front door, and a chimney top, solid bottom with air-diverter, and front air dams channel heated exhaust upward and out of the enclosure. The solid split rear door and pair of split flush-mount locking side panels close the airflow path while keeping equipment physically secure. The enclosure is Lever Lock compatible and accepts all 21-inch vertical Lever Lock accessories, providing tool-free Zero-U mounting for encoders, power supplies, and access control system components. UL/ETL listing and seismic certification support specification in government and institutional projects. Four casters are included for positioning the loaded enclosure during installation, with four leveling feet for final placement. The SNE24D-4542-P2 integrates cleanly into multi-rack rows alongside other SNE Series enclosures for larger commercial deployments.

Frequently Asked Questions

What types of equipment is the SNE24D-4542-P2 designed for?
It is configured for digital, IP-based security systems, including network switches, servers, network video recorders, and high-density structured cabling common in commercial surveillance and network deployments.

How does passive chimney cooling work in this enclosure?
Air enters through the 70 percent open vented front door, and the chimney top, solid bottom with air-diverter, and front air dams direct heated air upward and out without fans, so there is no fan noise or powered ventilation to maintain.

Is mounting hardware included?
Yes. The enclosure ships with two pairs of adjustable cage-nut rackrail and 100 6mm cage nuts and rack screws, so most equipment can be installed without additional hardware purchases.

Can I mount small devices like encoders and power supplies without using rack spaces?
Yes. The enclosure is Lever Lock compatible and accepts all 21-inch vertical Lever Lock accessories, providing tool-free Zero-U mounting along the sides of the rack.

Is this enclosure appropriate for seismic-rated projects?
Yes. The SNE24D-4542-P2 is UL/ETL listed and seismic certified, supporting government and institutional installations with seismic anchoring requirements.

How is the enclosure moved and installed on site?
Four included casters allow the enclosure to be rolled into position, and four leveling feet stabilize and level it at the final installation point.

What warranty and support are available?
The SNE24D-4542-P2 carries Middle Atlantic's manufacturer warranty. Creation Networks can assist with warranty details, rack elevations, and accessory selection — see our Middle Atlantic collection or contact our team for project support.
