Vertiv GL840ES-3248-W-MSS 44U Server Rack Enclosure — Winter White, Split Mesh Rear Door
The Vertiv GL840ES-3248-W-MSS is a 44U open-frame server rack enclosure built in a 32-inch wide by 48-inch deep footprint, finished in Winter White — a practical choice for data center environments where visual differentiation between rack rows, or compliance with facility color-coding standards, matters. The split mesh rear door configuration is the defining feature here: it provides rear airflow access while allowing partial cable or equipment access without swinging a full door panel clear of adjacent racks.
Overview
Part of Vertiv's Vertiv rack enclosure line, the GL840ES-3248-W-MSS fits into the broader network cabinets and server racks category for IT infrastructure and data center deployments. The 44U usable height handles standard 1U/2U server and switch stacking across mid-size deployments. At 32 inches wide and 48 inches deep, the cabinet accommodates deeper 1U and 2U rack-mount appliances — including most 1U servers, patch panels, and network switches — without forcing front-to-back cable compression.
Key Features
- 44U Usable Height: Fits a full stack of standard 1U and 2U rack-mount gear. For a typical mixed IDF (patch panels, PoE switches, UPS), 44U leaves meaningful room to grow without a second cabinet.
- 32" Width: Standard 19-inch EIA rack rail width with a wider outer footprint than a 24-inch cabinet — gives more side clearance for cable management arms and vertical PDU mounting without fighting for space.
- 48" Depth: Accommodates deep 1U servers and full-depth appliances. If your equipment is shallower than 30 inches, a cable management accessory at the rear rail is worth planning for to keep runs tidy.
- Split Mesh Rear Door: Two independently hinged rear door panels instead of a single full-width panel. In tight rows or against a wall, being able to open one half at a time is a real operational benefit — no full door swing required for rear cable work.
- Mesh Contour Front Door: Perforated mesh front allows passive airflow through the cabinet face, reducing hot-spot risk on densely populated shelves without requiring active front-panel fan trays.
- Winter White Finish: Distinguishes this cabinet from standard black enclosures in mixed-purpose or open-office adjacent deployments. Consistent with facilities that color-code by function (white = network, black = compute, for example).
