Middle Atlantic SNE24D-4248-P1AB – 24" 42U 48" Digital Enclosure Add-a-Bay

Product Overview

The Middle Atlantic SNE24D-4248-P1AB is a 24-inch-wide, 42U, 48-inch-deep SNE Series Digital enclosure configured as a passive-cooling Add-a-Bay expansion unit. It ships fully configured with 70% open vented front and split rear doors, a solid top with brush cable pass-through, two pairs of cage-nut rack rails, and 100 6mm cage nuts. Designed for IP-based security and networking systems, it expands an existing SNE Digital installation without requiring active cooling infrastructure.

Product Description

The SNE24D-4248-P1AB is part of Middle Atlantic's SNE Series Digital line, which targets high-density digital security systems combining IP cameras, network equipment, servers, and access control hardware. The Add-a-Bay (P1AB) designation indicates this unit is a passive-cooling expansion cabinet intended to extend an existing SNE Digital enclosure row rather than serve as a standalone primary cabinet. At 24 inches wide and 48 inches deep, it sits within a standard raised-floor tile footprint while providing 42U of usable rack space for additional equipment. Passive front-to-rear airflow is managed through a 70% open-area vented front door and a 70% open-area split rear door, eliminating the need for active fan trays when equipment heat loads fall within passive thermal ratings. The solid top panel includes a brush cable pass-through strip for routing power, data, and fiber between cabinets without exposing open gaps. Two pairs of adjustable cage-nut rack rails are included, meeting server manufacturer warranty specifications and accommodating mixed-vendor equipment. Lever Lock compatibility allows encoders, power supplies, and small access control modules to mount in unused rack spaces. UL/ETL listing and seismic certification satisfy code requirements in regulated installations. Four leveling feet and four casters are included; casters allow positioning under load, and feet stabilize the cabinet in its final location. The SNE24D-4248-P1AB pairs with other SNE24D and SNE24 cabinets in multi-bay security system enclosures, sharing the same external dimensions for a flush row alignment.

Frequently Asked Questions

What does "Add-a-Bay" mean for the SNE24D-4248-P1AB?

The Add-a-Bay (P1AB) designation means this cabinet is an expansion unit intended to be deployed alongside an existing SNE Digital primary enclosure. It shares the same external dimensions and panel configuration, allowing it to sit flush in a multi-bay row without gaps or mismatched trim.

Does passive cooling handle full server loads?

Passive front-to-rear airflow through 70% open doors is suitable for standard IP security system loads including NVRs, managed switches, and access control servers. High-density compute or storage loads generating significant heat may require active fan trays or supplemental cooling.

What is the difference between SNE24D-4248-P1AB and SNE27D-4536-P1AB?

The SNE24D-4248-P1AB is 24 inches wide and 48 inches deep with 42U of space. The SNE27D-4536-P1AB is 27 inches wide and 36 inches deep with 45U of space. Select based on your row width constraints and the depth of equipment being mounted.

Are cage nuts included?

Yes. One hundred 6mm cage nuts and rack screws are included, providing enough hardware for a full cabinet load without a separate order.
