Middle Atlantic 30W 45SP/48D DIG Encl - SNE30D-4548-P1

Middle Atlantic SNE30D-4548-P1 Digital Security Network Enclosure

Overview

The Middle Atlantic SNE30D-4548-P1 is a 45U, floor-standing steel network enclosure purpose-built for digital security and network infrastructure deployments where structured cabling, passive airflow, and long-term mechanical integrity matter. At 30 inches wide and 48 inches deep, this enclosure is sized for high-density NVR/server configurations and deep switching hardware — not a general-purpose patch cabinet. It ships TAA-compliant and manufactured in the United States, which satisfies federal procurement and GSA contract requirements without requiring supplemental documentation.

The SNE30D-4548-P1 belongs to Middle Atlantic's SNE series of rack enclosures — a line designed around the physical infrastructure needs of surveillance and security system integrators rather than generic IT closet use.

Key Features

• 45U Rack Height: 45U of usable rack space in an 84.75-inch overall footprint gives you room to house an NVR stack, PoE switching, patch panels, and UPS without splitting across multiple enclosures — reducing cable runs between chassis and simplifying maintenance windows.
• 30W x 48D x 84.75H Form Factor: The 48-inch depth is the critical dimension here. Most deep-chassis servers, storage arrays, and enterprise NVRs run 26–35 inches in depth; 48 inches provides clearance for cable dressing behind equipment without forcing bend-radius violations on fiber or Cat6A trunks. The 30-inch width accommodates standard 19-inch rack equipment with enough lateral clearance for vertical cable managers on both sides.
• 70% Open Front and Split Rear Doors: Passive cooling depends entirely on unrestricted airflow. The 70% open perforation on the front door and the 70% open split rear door allow hot/cold aisle convection without forcing active cooling infrastructure. In a conditioned equipment room, this eliminates the cost and maintenance overhead of fan trays while keeping the interior accessible without full door removal.
• Solid Top Panel: A solid top prevents overhead cable drops from bypassing the rear cable management path and blocks particulate entry from ceiling plenum environments — relevant in warehouse or manufacturing deployments where dust and fiber ingress are real concerns.
• Fully Welded Steel Construction: Welded frames eliminate the flex and rattle that plague bolt-together racks under heavy load. This matters when stacking 2U rackmount NVRs with multiple drive bays — the frame stays square, rack ears stay aligned, and equipment doesn't bind or require re-torquing after the first load cycle.
• Ganging Capability When Loaded: The SNE30D-4548-P1 (often searched as SNE30D 4548 P1) is engineered so multiple enclosures gang together when equipment is installed — distributing lateral load across the array rather than relying on independent foot contact. This is the correct way to deploy side-by-side enclosures in a security operations center or large IDF room.
• 3,000 lb Maximum Load Capacity: A 3,000-lb rated capacity is not a marketing figure — it defines how much combined rack equipment, cable, and UPS weight the frame will carry without structural deformation. A fully loaded 45U rack with enterprise UPS and dense NVR storage can exceed 1,500 lbs; this enclosure is rated for it.
• Includes 2 Pairs Adjustable Cage-Nut Rackrails + 100 6mm Cage Nuts: Ships with the hardware you actually need to mount equipment immediately. Adjustable cage-nut rackrails let you position front and rear rails independently to match varying chassis depths — a requirement for mixed hardware environments where NVRs, switches, and patch panels each have different mounting ears.
• TAA Compliant, Made in USA: Manufactured in the United States and compliant with the Trade Agreements Act. Required for federal agency deployments, state/local government projects referencing FAR provisions, and any integrator working under a GSA schedule. Verify TAA status with your contracting officer for specific procurement vehicles.
• Black Textured Finish: The textured black powder coat is a functional choice in security environments — it resists fingerprinting during installation and reduces glare under overhead lighting in NOC and SOC environments where enclosure doors may remain open during operations.

Integration & Compatibility

The cage-nut rackrail system accepts standard 19-inch rackmount equipment — switches, NVRs, servers, patch panels, and UPS units with EIA-310 mounting ears will install without adapters. The adjustable rail depth accommodates chassis from shallow 1U network devices to deep 4-post mounted storage arrays. No proprietary tooling or Middle Atlantic-specific hardware is required for third-party equipment installation.

This enclosure is a natural housing choice for network video recorders in mid-to-large surveillance deployments, alongside the PoE network switches and patch infrastructure that feed them. When planning rack density, factor cable management vertical space — the 30-inch width supports dual-sided vertical managers, but that consumes the lateral space between adjacent enclosures if ganged.

For deployments referencing a rack enclosure planning guide, the SNE series depth allows rear horizontal cable managers to be installed without conflicting with equipment airflow exhaust. Coordinate floor cutout or overhead ladder rack entry points with the 84.75-inch overall height before installation — standard 96-inch ceiling clearance is required for vertical cable entry with bend radius clearance.

Frequently Asked Questions

Q: Is the SNE30D-4548-P1 TAA compliant?

A: Yes. The SNE30D-4548-P1 is TAA compliant and manufactured in the United States, making it eligible for federal and government contract procurements that require TAA compliance under the Trade Agreements Act.

Q: What is the maximum load capacity of the SNE30D-4548-P1?

A: The SNE30D-4548-P1 is rated for a maximum load capacity of 3,000 lbs, accommodating fully loaded NVR stacks, enterprise UPS units, and dense storage arrays without structural compromise.

Q: Does the SNE30D-4548-P1 include rackrails and cage nuts?

A: Yes. It includes 2 pairs of adjustable cage-nut rackrails and 100 6mm cage nuts, providing everything needed to mount standard 19-inch EIA-310 equipment immediately upon installation.

Q: How many rack units does the SNE30D-4548-P1 support?

A: The SNE30D-4548-P1 provides 45U of usable rack space within an overall enclosure height of 84.75 inches.

Q: Can multiple SNE30D-4548-P1 enclosures be installed side by side?

A: Yes. The SNE series is engineered to gang together when loaded, distributing lateral load across the array. This is the intended configuration for multi-enclosure deployments in security operations centers and large IDF rooms.

Q: What type of cooling does the SNE30D-4548-P1 use?

A: The SNE30D-4548-P1 uses passive cooling via a 70% open perforated front door and 70% open split rear door, enabling natural convection airflow without fan trays or active cooling components. A solid top panel completes the enclosure.
