Middle Atlantic SNE30D-4548-P1AB – 30" 45U 48" Add-a-Bay Enclosure

Product Overview

The Middle Atlantic SNE30D-4548-P1AB is a 30-inch wide, 45U, 48-inch deep Slim Network Enclosure in the Digital configuration featuring an Add-a-Bay (AB) gang expansion design, built for installations that need to expand an existing SNE rack system without replacing existing cabinets. The AB model mounts directly to a primary SNE enclosure, extending the rack row with a shared side panel and consistent thermal management. Long-tail search terms: Middle Atlantic SNE Add-a-Bay gang expansion rack enclosure, 45U 48-inch deep digital enclosure expansion bay chimney cooling.

Product Description

The SNE30D-4548-P1AB is designed specifically as a secondary bay that attaches to a compatible primary SNE enclosure, making it the correct procurement choice when an existing SNE installation needs capacity added rather than replaced. The Add-a-Bay (AB) configuration eliminates the redundant side panel between the primary and expansion units, creating a contiguous interior that simplifies cable routing between adjacent bays and presents a unified rack wall appearance. At 30 inches wide, 45U tall, and 48 inches deep, the expansion bay matches the largest Digital enclosure dimensions in the SNE line, accommodating extended-depth servers, large UPS units, and rear-mounted cable management alongside the primary bay. The Digital enclosure format means the expansion bay shares the chimney cooling architecture, routing exhaust heat vertically through its own plenum column in coordination with adjacent units. The P1 passive rear door provides 70 percent open area for front-to-rear airflow driven by equipment-internal fans. This model is particularly relevant for data center and broadcast facility buildouts where initial installation footprint is limited but future expansion is planned, and for enterprise IT infrastructure teams that want a scalable rack standard without the cost of purchasing pre-sized multi-bay frames upfront. Adjustable mounting rails, casters, and leveling feet are included. The SNE30D-4548-P1AB is available from Creation Networks, an authorized Middle Atlantic distributor.

• AV infrastructure rooms extending SNE installations to accommodate new equipment

Technical Specifications

Frequently Asked Questions

What does Add-a-Bay (AB) mean?

Add-a-Bay is Middle Atlantic's designation for an expansion enclosure designed to attach directly to a compatible primary SNE cabinet. The shared side panel between primary and expansion units is removed, creating a contiguous interior for cross-bay cable routing and a unified rack wall appearance.

Can the SNE30D-4548-P1AB be used as a standalone enclosure?

The AB model is specifically designed as a gang expansion unit. Using it as a standalone enclosure is not recommended, as the design assumes attachment to a compatible primary SNE bay for structural and thermal integration.

Which primary SNE enclosures is this compatible with?

The SNE30D-4548-P1AB is designed to gang with compatible 30-inch wide SNE Digital enclosures. Confirm compatibility with the specific primary model with Middle Atlantic or your authorized distributor before ordering.

Does the expansion bay have its own chimney exhaust column?

Yes. Each Digital SNE unit includes its own chimney column for vertical exhaust, so the expansion bay manages its own thermal load independently while being physically integrated with the primary bay.

Is this the right model if I am building a new rack row from scratch?

If you are starting a new installation, order a standard primary SNE30D-4548-P1 as the first unit, then add SNE30D-4548-P1AB units for each additional bay. The AB model is a secondary expansion unit, not a standalone primary enclosure.

Where can I order the SNE30D-4548-P1AB?

Available at creationnetworks.net, an authorized Middle Atlantic distributor serving AV integrators and IT infrastructure teams.

What depth equipment fits in the 48-inch interior?

Extended-depth servers, large UPS systems, rear-mounted PDUs, and standard AV processing equipment all fit within the 48-inch interior depth of this expansion bay.
