Vertiv 9801ES-2448-B 52U 24x48 Server Rack Enclosure
Overview
The Vertiv 9801ES-2448-B is a 52U ES-series server rack built around a 24-inch-wide by 48-inch-deep footprint — a configuration that balances dense equipment loading with standard data center floor tile spacing. At 52U of usable rack space, it accommodates full-height server, network, and power distribution builds without the floor-plan penalty of wider enclosures. If you are standardizing rack layouts across a new data center row or expanding an existing Vertiv ES-frame deployment, the 9801ES-2448-B (often searched as 9801ES 2448 B) is a direct drop-in to that ecosystem.
Key Features
- 52U Rack Height: 52U provides enough vertical space to house dense compute stacks — full-depth 1U/2U servers, top-of-rack switching, and a dedicated patch panel zone — without splitting workloads across two enclosures. That consolidation simplifies cable routing and reduces per-rack PDU costs.
- 24-Inch Width: The 24-inch external width fits within standard 600mm data center column spacing. If your raised-floor tiles are laid out in 600mm increments, this rack installs without row reconfiguration — a real time-saver on phased builds.
- 48-Inch Depth: A 48-inch internal depth clears most enterprise-class servers and full-depth UPS units without the wasted airspace you get in a 36-inch cabinet. Front-to-rear airflow paths remain unobstructed, which matters for in-row cooling designs.
- Black Finish: The black powder coat matches standard Vertiv ES-series enclosures, keeping multi-rack rows visually consistent. Color consistency is a minor point, but inconsistent rack colors in client-facing colocation environments do get noticed.
- ES-Frame Platform: The ES-frame line is Vertiv's commercial-grade enclosure series — designed for integration with Vertiv cable management, blanking panels, power distribution, and side panels, so you are not sourcing third-party accessories to complete the build.
Integration & Compatibility
The 9801ES-2448-B integrates with the Vertiv rack enclosure catalog, including ES-series side panels, cable management arms, and PDU mounting options. The 24-inch width and 48-inch depth conform to EIA-310 rack unit standards, meaning standard 19-inch rack-mount equipment installs without adapter rails. If you are planning a full rack infrastructure build, review the network infrastructure catalog for compatible patch panels, cable pathways, and PoE switching that pairs with this enclosure in structured wiring deployments. For power distribution within the rack, the Vertiv Power & UPS category includes rack-mount PDU options purpose-built for the ES-frame depth. See the network switch catalog for top-of-rack switching options sized to the 52U build space.
Frequently Asked Questions
Q: What are the external dimensions of the 9801ES-2448-B?
A: The 9801ES-2448-B is specified at 24 inches wide and 48 inches deep with 52U of rack height. Exact external height in millimeters or inches should be confirmed against the Vertiv ES-series datasheet for precise floor-plan planning.
Q: Is the 9801ES-2448-B compatible with standard 19-inch rack equipment?
A: Yes — the ES-series frame conforms to EIA-310 19-inch rack unit standards, so standard 1U/2U/4U rack-mount servers, switches, and PDUs install without adapters.
Q: Can I expand a row of 9801ES-2448-B enclosures with Vertiv side panels and cable management?
A: The 9801ES-2448-B is part of the Vertiv ES-frame platform, which is designed to accept Vertiv-branded side panels, cable management, blanking panels, and PDU accessories within the same enclosure family.
Q: What is the color of the 9801ES-2448-B?
A: Black powder coat — consistent with the standard Vertiv ES-series enclosure finish.
Q: Is the 9801ES-2448-B suitable for a raised-floor data center environment?
A: The 24-inch-wide footprint is compatible with standard 600mm raised-floor tile grid spacing, making it a practical choice for traditional data center row builds.
The Vertiv 9801ES-2448-B comes up most often in rack standardization projects where the team has committed to 24-inch-wide enclosures across a data center row — the 48-inch depth is the key dimension here, because it's the minimum you need to clear most 2-post-mountable UPS units and full-depth servers in the same cabinet without a depth extender kit.
Technical Highlights:
- 52U Capacity: 52U lets you run a complete server + networking + power stack in a single enclosure — typically 20–30 compute units, a pair of top-of-rack switches, and a vertical PDU — without hitting the ceiling. That headroom matters when a project adds blade chassis late in the build.
- 24-Inch Width: Fits a 600mm floor tile column exactly, which simplifies aisle layout math on raised-floor sites. No partial tile overhangs, no custom cutouts.
- 48-Inch Depth: The 48-inch internal run accommodates front-to-rear cable-managed server deployments with room for a rear vertical cable manager — something a 36-inch enclosure forces you to sacrifice.
Deployment Considerations:
- Confirm the static load rating against your heaviest planned configuration before committing to a full row — Vertiv's ES-series spec sheets publish this; the 9801ES-2448-B page is the place to verify it before you sign off on a BOM.
- The 24-inch width assumes you are not running side-by-side with a 600mm cold-aisle containment door system that requires a 30-inch enclosure clearance — check your containment vendor's tolerance spec.
This enclosure is the right call for a structured data center row build where you need EIA-310 compliance, Vertiv ecosystem accessory compatibility, and a 48-inch depth that doesn't force equipment compromises at the back of the cabinet.
