Middle Atlantic SNE27H-4536-A2 – 45U Hybrid Security Network Enclosure

Product Overview

The Middle Atlantic SNE27H-4536-A2 is a pre-configured 45U hybrid security network enclosure for installations that combine analog and digital equipment in the same rack. At 27.6 inches wide with a space-efficient 36-inch depth, this SNE Series hybrid rack enclosure delivers maximum rackspace capacity in rooms where floor depth is limited — a common constraint in retrofitted equipment closets and shared technical spaces. Active rear ventilation with a high-capacity fan door keeps mixed equipment loads cool, making it a strong fit for commercial AV integration, IP surveillance head ends, and network equipment deployment.

Product Description

System migrations rarely happen all at once. Facilities moving from analog CCTV and matrix-based AV systems to IP infrastructure typically run both technologies in parallel for years, and the SNE Series Hybrid is engineered for that reality. The SNE27H-4536-A2 ships fully configured with two pairs of adjustable 10-32 tapped rackrail for traditional rack-mount equipment, plus a four-space cage-nut adaptor (pair) for servers, switches, and other hardware that requires cage-nut mounting. With 45 rackspaces in a 36-inch-deep footprint, it offers more usable capacity than deeper 42U cabinets while fitting equipment rooms where a 42- or 48-inch-deep enclosure simply will not work.

Thermal management is handled by the A2 rear active ventilation configuration: a 70% open area front door admits cool air, and a 1,760 CFM split fan rear door with eight 6-inch fans (expandable) exhausts heat from the rear of the cabinet beneath a solid top. The enclosure is Lever Lock compatible and includes two vertical 10-inch wide Lever Lock accessory mounting plates, so power supplies, encoders, and access control devices mount tool-free without occupying rackspaces. A 6-inch wide vertical wire grid lace strip organizes high-density cable runs, and a pair of split flush-mount locking side panels secures the installed electronics. UL listing and seismic certification support specification in government and institutional projects, while the included casters and leveling feet streamline rack integration from staging through final placement.

Key Features

• 45U Capacity in a 36-Inch Depth — Delivers maximum rackspaces in a shallower footprint that fits retrofitted equipment rooms and tight network closets.
• Hybrid Mounting System — Two pairs of 10-32 tapped adjustable rackrail plus a four-space cage-nut adaptor support analog and digital equipment in one enclosure.
• Rear Active Ventilation — The A2 configuration pairs a 70% open front door with an active fan rear door to keep dense equipment loads within operating temperature.
• 1,760 CFM Split Fan Rear Door — Eight 6-inch fans move substantial airflow and can be expanded as system heat loads grow.
• Lever Lock Compatible — Includes two vertical 10-inch Lever Lock accessory mounting plates for tool-free mounting of small devices outside the rackrail.
• Built-In Cable Management — A 6-inch wide vertical wire grid lace strip keeps structured cabling dressed, labeled, and serviceable.
• Locking Split Side Panels — Flush-mount locking side panels restrict physical access to security and network equipment.
• UL Listed and Seismic Certified — Certifications support installation in government spaces and other code-driven commercial facilities.
• Mobility and Leveling Included — Four casters simplify positioning during integration and four leveling feet stabilize the final installation.

Typical Applications

• Government space — surveillance and access control head ends transitioning from analog to IP
• Commercial meeting space — central AV and network racks serving conference room clusters
• Broadcast studio — mixed analog and digital equipment racks in technical operations rooms
• Auditorium — equipment rooms supporting AV, network, and building security systems
• House of worship — head-end enclosures for production, streaming, and campus systems

Technical Specifications

Frequently Asked Questions

How does the SNE27H-4536-A2 differ from deeper SNE hybrid models?
It provides 45 rackspaces in a 36-inch-deep cabinet, trading rear depth for vertical capacity. It suits rooms where a 42- or 48-inch-deep enclosure will not fit, provided your equipment chassis and rear cabling fit the shallower footprint.

What equipment mounting options are included?
Two pairs of adjustable 10-32 tapped rackrail handle traditional analog and AV gear, while the included four-space cage-nut adaptor accepts network switches, servers, and other hardware that requires cage-nut mounting.

How is heat managed in this enclosure?
The A2 rear active ventilation configuration draws air through the 70% open front door and exhausts it through a 1,760 CFM split fan rear door with eight 6-inch fans, expandable for higher heat loads.

Is it compatible with Middle Atlantic Lever Lock accessories?
Yes. The enclosure is Lever Lock compatible and includes two vertical 10-inch wide accessory mounting plates for tool-free mounting of power supplies, encoders, and access control modules.

Does it meet certification requirements for government projects?
Yes. The SNE27H-4536-A2 is UL listed and seismic certified, which supports specification in government, education, and other regulated commercial facilities.

Can one installer position the enclosure on site?
The included four casters allow the enclosure to be rolled into position during integration; four leveling feet then stabilize it at the final installed location.

What cable management is provided?
A 6-inch wide vertical wire grid lace strip is included, and the 27.6-inch width leaves side channels for additional vertical cable management accessories.
