Vertiv 7901ES-2448-B 42U Open Equipment Rack Frame
Overview
The Vertiv 7901ES-2448-B is a 42U rack frame built for structured equipment deployments where maximizing usable rack space and airflow access matter more than an enclosed cabinet. At 24 inches wide and 48 inches deep, it accommodates standard EIA-310-compliant equipment across network, server, and physical security applications — from NVRs and video management servers to patch panels and PoE switch stacks. If you are sourcing rack infrastructure to anchor a Vertiv equipment deployment, this is the baseline open-frame enclosure in the ES series.
The 42U height gives you 73.5 inches of usable rack unit space — enough to house a full camera head-end: NVR or VMS server, managed PoE switches, UPS, and cable management horizontals without stacking constraints. The 48-inch depth accommodates deeper 1U and 2U rackmount appliances that shorter 2-post frames cannot support. The black finish is standard for finished equipment rooms and server closets where aesthetics matter alongside function.
This frame carries part number 7901ES-2448-B (sometimes searched as 7901ES 2448 B) and UPC 767041065275. It is a factory-new, genuine Vertiv unit sourced from US distribution — no grey-market, no parallel imports.
Key Features
- 42U Height: 73.5 inches of total rack unit capacity — large enough to consolidate an entire security head-end (NVRs, switches, UPS, patch panels) into a single enclosure footprint, reducing floor space requirements in IDF closets.
- 24-Inch Width: Matches the EIA-310 standard 19-inch equipment mounting rail spacing while keeping the overall frame footprint compatible with standard raised-floor tiles and tight-aisle rows.
- 48-Inch Depth: Accommodates deep rackmount servers and NVR appliances that typical 36-inch frames cannot house without equipment overhang — critical when deploying high-channel-count network video recorders and storage arrays side by side.
- Open Frame Design: Unrestricted airflow on all sides reduces hotspot risk in dense deployments. Easier cable dressing and equipment access compared to fully enclosed cabinets — a practical advantage during initial rack build-out and future equipment swaps.
- Black Finish: Standard in finished equipment rooms, data centers, and security operations centers where rack aesthetics are specified alongside function.
- ES Frame Series: Part of Vertiv's ES open-frame line, designed for structured cabling and equipment deployments. Pair with compatible rack accessories including cable managers, blanking panels, and PDUs from the same platform family.
Integration and Compatibility
The 7901ES-2448-B follows standard EIA-310-D 19-inch rack unit conventions, making it compatible with virtually all rackmount security and networking equipment — managed PoE switches, 1U/2U NVR appliances, rackmount UPS units, and patch panels. Verify mounting rail type (square-hole vs. round-hole vs. threaded) against your equipment's rail compatibility requirements before ordering, as the ES frame series rail configuration should be confirmed from the Vertiv product datasheet.
For enclosed cabinet installations or deployments requiring side panels, doors, or integrated cable troughs, consider the Vertiv VR or VS series enclosed rack cabinets as alternatives within the server rack and enclosure category.
Frequently Asked Questions
Q: What are the physical dimensions of the Vertiv 7901ES-2448-B?
A: The 7901ES-2448-B is a 42U rack frame with a 24-inch width and 48-inch depth. Exact exterior height in inches should be confirmed against the Vertiv product datasheet, as rack frame overall height includes structural elements beyond the usable 42U of equipment space.
Q: Is the 7901ES-2448-B an open-frame rack or an enclosed cabinet?
A: The ES series designation indicates an open-frame rack, not an enclosed cabinet. There are no side panels, doors, or roof panels included. This is appropriate for equipment rooms with controlled access where airflow and cable access are prioritized over physical security of the enclosure itself.
Q: What type of equipment can be mounted in the 7901ES-2448-B?
A: Any standard EIA-310-D 19-inch rackmount equipment fits — including NVRs, managed switches, UPS units, servers, and patch panels. The 48-inch depth accommodates deeper appliances that shallower frames cannot support. Confirm rail type compatibility with your specific equipment before installation.
Q: Does the 7901ES-2448-B include mounting hardware or accessories?
A: Package contents are not confirmed in available evidence. Contact the seller or consult the Vertiv product datasheet to confirm what hardware ships with the frame.
Q: What is the UPC for the Vertiv 7901ES-2448-B?
A: The UPC is 767041065275.
When I look at the 7901ES-2448-B, the spec that drives most purchasing decisions is the 48-inch depth combined with the full 42U height. That combination is what you need when you are building a consolidated physical security head-end — not a shallow 2-post telco frame that forces you to hang NVR appliances and PoE switch stacks off the back edge.
Technical Highlights:
- 42U Capacity: 73.5 inches of rack unit space — sufficient to stack a high-channel NVR, redundant managed switches, a rackmount UPS, and horizontal cable managers without running out of U-space mid-project.
- 48-Inch Depth: Accommodates 1U and 2U appliances that often run 28–42 inches in body length. A 36-inch frame forces you to either overhang equipment or choose shorter (often lower-spec) appliances — the 48-inch depth removes that constraint.
- Open-Frame Architecture: No doors or side panels means unrestricted front-to-back airflow, which matters in high-density deployments where multiple active appliances generate sustained heat loads without the benefit of a precision-cooled enclosure.
Deployment Considerations:
- Confirm rail type (square-hole, round-hole, or threaded) before ordering rackmount equipment — open frames in this series may ship with a specific rail configuration that not all 19-inch equipment supports without adapter hardware.
- Open-frame racks are not appropriate for unsecured or publicly accessible spaces. If the installation environment requires physical access control at the enclosure level, specify an enclosed locking cabinet instead.
The 7901ES-2448-B fits best in a controlled equipment room or IDF closet anchoring a multi-camera security deployment — particularly where deep NVR servers or storage expansion units are part of the design and a full 42U of vertical space is needed to keep the entire head-end in one rack footprint.
