Vertiv GL910ES-3042-W-MSS 48U 30" × 42" Winter White Split Rear Door Rack Enclosure

Overview

The Vertiv GL910ES-3042-W-MSS is a 48U rack enclosure in the Geist ES cabinet series, configured at 30 inches wide and 42 inches deep, finished in Winter White with a split mesh rear door. This is the model to specify when your network infrastructure or security rack needs to stand out in a white-interior data room or NOC, or when a split rear door is operationally required for half-height rear access without swinging a full panel into a tight aisle.

The GL910ES-3042-W-MSS (often searched as GL910ES 3042 W MSS) sits in Vertiv's ES enclosure lineup, which spans 24U through 52U heights and 24", 30", and 32" widths — so if you are quoting a project that needs a different unit count or footprint, a sibling model in the same ES family can match without changing your rack accessories or cable management strategy.

Key Features

• 48U Usable Height: 48 rack units accommodates a fully loaded security stack — NVRs, PoE switches, patch panels, UPS, and KVM — without stacking a second enclosure. That matters when floor space is charged by the cabinet in a colocation or IDF room.
• 30" Width: The 30-inch width is the most common rack footprint for IT and physical security deployments. It fits standard 19-inch rackmount equipment with side clearance for internal vertical cable managers, and it ships through most freight doors without special handling.
• 42" Depth: 42 inches of interior depth handles deep 2-post servers, high-density patch fields, and rear-mounted PDUs without forcing cable compression. For reference, most 1U switches and NVRs run 12–20 inches; you will not run out of room front-to-back at 42".
• Winter White Finish: The Winter White color is not a cosmetic afterthought — it is a practical spec in healthcare environments, clean-room adjacencies, and retail back-of-house deployments where a black cabinet reads as out-of-place or conflicts with facility standards. Specify this finish on the front end to avoid a repaint or swap-out discussion at installation.
• Split Mesh Rear Door (MSS): The split rear door divides at mid-height, letting technicians open the top or bottom half independently. This is a direct operational benefit in live racks where pulling a full rear door risks snagging active cables or bumping neighboring equipment. Mesh panels maintain airflow while the door is closed — passive cooling is not compromised.
• Mesh Contour Front Door: The front mesh contour door allows intake airflow for active equipment without requiring blanking panels on every unused U. For video surveillance NVRs and network appliances that draw ambient air from the front, this is the right door type — perforated or mesh front doors consistently outperform solid front doors in thermal testing at mid-to-high rack densities.
• Multiple Configuration Options: The ES series offers heights from 24U to 52U, widths of 24", 30", and 32", and depths of 42" or 48", with Black or Winter White finish and multiple door configurations. If your rack plan changes post-quote, you can substitute within the family without retraining installers or switching mounting hardware.

Integration and Compatibility

The GL910ES-3042-W-MSS follows standard EIA-310 19-inch rack rail spacing, making it compatible with any rackmount equipment — network video recorders, PoE switches, UPS units, patch panels, and access control appliances. The 30"W × 42"D footprint is a common raised-floor tile boundary in IT environments; confirm your facility's tile grid before finalizing placement in a data center application. For installations requiring seismic bracing, active cooling, or integrated PDUs, verify compatibility with Vertiv's ES-series accessory catalog separately — those specs are not part of this SKU's evidence and should not be assumed.

Frequently Asked Questions

Q: What door configuration does the GL910ES-3042-W-MSS ship with?

A: The GL910ES-3042-W-MSS ships with a mesh contour front door and a split mesh rear door (MSS). The split rear door opens as two independent halves, allowing top or bottom rear access without swinging the full panel.

Q: Is the GL910ES-3042-W-MSS available in black?

A: The GL910ES-3042-W-MSS is specifically the Winter White configuration. The Vertiv ES series offers the same enclosure in black under a different model number. If black finish is required, specify accordingly when ordering.

Q: What equipment depth does the GL910ES-3042-W-MSS support?

A: The interior depth is 42 inches. This accommodates most 1U–4U rackmount equipment — switches, NVRs, servers, and patch panels — with room for rear cable management and PDU mounting.

Q: What rack unit height options are available in the Vertiv ES series?

A: The ES series spans 24U, 42U, 44U, 48U, and 52U heights. The GL910ES-3042-W-MSS is the 48U variant at 30" wide and 42" deep in Winter White.

Q: Will standard 19-inch rackmount equipment fit in the GL910ES-3042-W-MSS?

A: Yes. The enclosure uses standard EIA-310 19-inch rail spacing. Any rackmount appliance — NVRs, PoE switches, UPS units, KVM drawers — installs without adapter brackets.
