Vertiv 4801ES-2442-B 24U Server Rack Enclosure
Overview
The Vertiv 4801ES-2442-B is a 24U, 24-inch wide, 42-inch deep black server enclosure designed for structured equipment deployments in data centers, server rooms, and network closets. The 24U height accommodates a dense but manageable stack of 1U and 2U servers, switches, and patch panels without requiring a full 42U floor footprint — a practical fit for mid-size server rooms or secondary equipment rooms where floor space is a real constraint. The 4801ES-2442-B (often searched as 4801ES 2442 B) ships in a black finish, consistent with standard data center aesthetics and common rack color matching requirements.
Key Features
- 24U Usable Height: Fits a practical mix of 1U servers, 2U appliances, and patch panels without committing to a full 42U cabinet — right-sized for branch office server rooms, secondary comms closets, or surveillance NVR/server stacks where vertical space is limited.
- 24-Inch Width: Standard 19-inch EIA rail spacing within a 24-inch outer width allows direct mounting of all standard rackmount equipment. The outer width fits through most standard doorframes without disassembly.
- 42-Inch Depth: The 42-inch depth accommodates most 1U and 2U servers with standard cable management clearance behind — verify against your deepest server's cable egress before ordering, as some high-density storage servers or UPS units run deeper.
- Black Finish: Matches standard black rack environments and blends with common raised-floor or open-frame data center aesthetics. Consistent color across multi-rack rows where visual uniformity matters.
Deployment Context
This enclosure is suited for environments deploying a moderate number of rackmount devices — security appliances, NVRs, network switches, and patch infrastructure — in a footprint-constrained space. The 24U form is a common choice for network video recorder stacks paired with PoE switching and storage in a single enclosure. For larger deployments requiring full 42U capacity or wider 600mm spacing for high-density blade or storage chassis, consider a larger Vertiv enclosure in the same family.
Note: The 4801ES-2442-B was marked discontinued as of June 2026. Verify current availability and confirm no updated replacement model has been released before placing a volume order. See the broader racks and enclosures category for current active alternatives.
Frequently Asked Questions
Q: What is the usable rack unit capacity of the 4801ES-2442-B?
A: The 4801ES-2442-B provides 24U of usable rack space, suitable for 1U and 2U servers, switches, and patch panels.
Q: What are the outer dimensions of the 4801ES-2442-B?
A: The enclosure is 24 inches wide and 42 inches deep. Exact height in inches is not confirmed in available evidence — reference the manufacturer's datasheet for precise shipping and installed dimensions.
Q: Is the 4801ES-2442-B still in production?
A: No. This model was discontinued as of June 9, 2026. Check current Vertiv rack offerings for an actively manufactured replacement.
Q: What equipment fits in the 4801ES-2442-B?
A: Any standard 19-inch EIA rackmount equipment up to 24U total — including 1U/2U servers, NVRs, PoE switches, patch panels, and 1U/2U UPS units — provided each device's depth does not exceed the available interior depth.
Q: Does the 4801ES-2442-B come in colors other than black?
A: Available evidence confirms only the black finish for this model number. Other color variants, if offered by Vertiv, would carry different model numbers.
The 4801ES-2442-B is a straightforward 24U enclosure in Vertiv's ES Frame line — 24 inches wide, 42 inches deep, black finish. It's the kind of cabinet that ends up in secondary server rooms and surveillance head-end closets where you need a solid, standards-compliant enclosure without over-building for the space.
Technical Highlights:
- 24U Capacity: Enough vertical space for a typical NVR stack — a 2U recorder, 1U PoE switch, 1U patch panel, and a 2U UPS — without unused rack units that just collect dust in a small closet.
- 42-Inch Depth: Covers most rack-mounted appliances and short-depth servers; tight on some deeper storage arrays, so measure your deepest device before committing.
- 24-Inch Width: Standard EIA 19-inch rail spacing inside a practical outer width — gets through most doorframes without removal of side panels or disassembly.
Deployment Considerations:
- This model was discontinued June 2026 — if sourcing for a multi-rack rollout, confirm long-term parts availability or identify the current replacement in Vertiv's active ES Frame lineup before purchasing in volume.
- The 42-inch depth is the spec most likely to cause a fit problem; always verify against your deepest device including cable egress, not just the chassis length.
Best fit for a security head-end or branch server room running a single NVR, a managed PoE switch, and a small UPS — where a full 42U floor cabinet is overkill and a wall-mount open frame isn't secure enough.
