Middle Atlantic SNE27D-4548-P1 – 45U 27-Inch Wide Security Network Enclosure

Product Overview

The Middle Atlantic SNE27D-4548-P1 is a fully configured 45U digital security network enclosure for IP-based security systems, network equipment, and servers with high-density cabling. The 27-inch width adds vertical cable channels beside the 19-inch mounting rails while keeping a tighter footprint than a 30-inch frame, making it a practical fit for equipment rooms where floor space is constrained. The 48-inch overall depth handles full-depth servers, and passive front-to-back cooling, cage-nut rackrail, and locking side panels come pre-installed. It is UL/ETL listed and seismic certified for commercial deployment.

Product Description

IP security and network head ends concentrate switches, servers, recorders, and dense structured cabling into a single enclosure. The SNE27D-4548-P1 is configured for exactly this load profile, providing 45 rackspaces in a 48-inch-deep frame with side channel width for managed vertical cable runs that a standard 24-inch rack cannot offer.

The thermal design follows data center practice with passive front-to-back airflow. The 70 percent open area vented front door supplies intake air, the 70 percent open split rear door exhausts it, and the solid top with brush cable pass-through admits overhead cabling without disrupting the airflow path. With no fan top, the enclosure operates silently, which matters when the rack sits in or adjacent to occupied work areas.

Equipment mounting uses two pairs of adjustable cage-nut rackrail with 6mm hardware, and 100 cage nuts and rack screws are included for installation day. The enclosure is Lever Lock compatible and accepts all 21-inch vertical Lever Lock accessories, giving integrators tool-free mounting for encoders, power supplies, and access control system components in the side channels. A pair of split flush-mount locking side panels secures the installed equipment, while four casters and four leveling feet make positioning and final leveling straightforward. Pair it with hardware from the Middle Atlantic collection at Creation Networks.

Frequently Asked Questions

How does the 27-inch width compare with the 24-inch and 30-inch SNE enclosures?
The 27-inch frame adds vertical cable channels beside the 19-inch rails for high-density cabling while occupying less floor width than the 30-inch version, making it a balanced choice for constrained equipment rooms.

What systems is the SNE27D-4548-P1 configured for?
It is built for digital, IP-based security and network deployments: switches, servers, NVRs, encoders, power supplies, and access control components with high-density structured cabling.

Does it include active cooling?
No. The P1 configuration relies on passive front-to-back airflow through the vented front and split rear doors, which suits equipment with internal front-to-rear fans and keeps the enclosure silent.

Is mounting hardware included?
Yes. Two pairs of adjustable cage-nut rackrail are pre-installed with 6mm hardware, and 100 cage nuts and rack screws ship with the enclosure.

Can small non-rackmount devices be mounted inside?
Yes. The enclosure accepts all 21-inch vertical Lever Lock accessories, allowing tool-free mounting of encoders, power supplies, and access control devices in the side channels.

Is this enclosure suitable for seismic-rated projects?
Yes. It is seismic certified and UL/ETL listed, supporting government, education, and healthcare specifications that call for these certifications.

What warranty and support are available?
Middle Atlantic enclosures are covered by the manufacturer's warranty. Creation Networks can assist with accessory selection, configuration questions, and volume quotes for commercial installations.
