Vertiv GL720E-2436-W-SQM6P 37U White Rack Enclosure with Plexi Front Door
Overview
The Vertiv GL720E-2436-W-SQM6P is a 37U, 24-inch-wide by 36-inch-deep rack enclosure finished in Winter White, configured with a plexiglass front door, solid (PV) rear door, and M6 square-hole (3/8" sq.) vertical rails. It is part of Vertiv's GL720E rack family, which spans heights from 13U to 44U and widths of 24" and 29", giving integrators the flexibility to right-size enclosures across mixed equipment rooms without switching suppliers or hardware ecosystems. The GL720E-2436-W-SQM6P specifically targets environments where equipment visibility from the front is operationally useful — think co-location edge closets, NOC floors, or campus IDF rooms where staff visually verify indicator lights without opening the rack.
The Winter White color designation makes this enclosure a practical match for clean-room labs, hospital IT spaces, education facilities, and broadcast control environments where black racks read as industrial and out of place. Color is not cosmetic here — it is a procurement decision that affects how a finished room looks on a facilities audit or during a client walk-through.
Key Features
- 37U Usable Height: 37U accommodates a dense mix of 1U switches, patch panels, and 2U–4U servers without forcing a secondary enclosure. It hits the sweet spot between the 31U (too shallow for most full server deployments) and 44U (overkill for branch or edge installs) options in the GL720E family.
- 24" Interior Width: The 24" footprint keeps the enclosure compatible with standard 19" EIA-310 equipment while fitting inside telecom closets and narrow equipment rooms that cannot accommodate a 29" chassis. If your equipment room is tight, confirm your floor tile or concrete cut-out before ordering the wider 29" variant.
- 36" Depth: 36" of usable depth handles 1U–4U servers, mid-depth patch panels, and most enterprise network switches without cable management becoming a fight at the rear. This is the deeper of the two GL720E depth options (32" and 36"), so it is the correct pick when you are housing full-depth server chassis or need dedicated rear cable management channels.
- Plexiglass Front Door: The transparent plexi front door allows technicians and NOC staff to read power and link indicators through the door — without unlocking and swinging it open — cutting mean-time-to-diagnose on indicator-based troubleshooting. Plexi also provides a physical barrier against accidental contact while maintaining visual access during a site walk.
- PV Solid Rear Door: The solid rear panel isolates rear cabling, power distribution, and patch terminations from the rest of the room. In multi-tenant or shared equipment rooms, a solid rear door limits visibility into proprietary cable routes and rear-panel configurations — a reasonable physical security posture even without supplemental locking beyond the door latch.
- M6 Square-Hole (3/8" sq.) Vertical Rails: M6 square-hole rails are the current standard for most data center and network equipment. Cage nuts and M6 screws are universally stocked by facilities teams and available through every major supplier. The #10-32 threaded option exists in the GL720E family for legacy equipment — this configuration ships with M6, so confirm your equipment's mounting specification before installing legacy servers that require #10-32 threads.
- Winter White Finish: The Winter White color coordinates with clean-room and clinical environments where standard black enclosures are flagged as non-conforming. This is a real procurement differentiator in healthcare IT, education, and broadcast, where the facilities team — not just the IT team — has sign-off authority on equipment appearance.
Integration and Compatibility
The GL720E-2436-W-SQM6P accepts standard 19" rack-mount equipment conforming to EIA-310. The M6 square-hole rails are compatible with cage-nut-mounted servers, switches, patch panels, KVM drawers, and PDUs from virtually every major vendor. For power distribution, standard 1U and 2U vertical PDUs designed for 36" depth enclosures mount cleanly at the rear without interference. The 36" depth supports most enterprise-class full-depth servers; verify that your specific server's depth — including cable egress at the rear — does not exceed the interior clearance before ordering.
The GL720E enclosure line is designed to integrate with Vertiv's broader infrastructure portfolio, including Vertiv UPS systems, thermal management units, and power distribution accessories, creating a single-vendor infrastructure stack for integrators who prefer consolidated vendor support. For installations requiring environmental monitoring, a third-party 1U sensor unit can be rack-mounted in a dedicated U position without modification.
Buyers specifying this enclosure for network closet deployments should also evaluate patch panel depth, cable management trays, and horizontal cable managers — all of which need to be sized to the 36" interior depth to avoid rear-door interference. See our rack accessories selection for compatible cable management and blanking panels.
Frequently Asked Questions
Q: What is the usable rack unit height of the GL720E-2436-W-SQM6P?
A: This enclosure provides 37U of usable rack space. The GL720E family spans 13U, 24U, 31U, 37U, and 44U height options — 37U is the second-tallest configuration and suits most medium-density server and network deployments.
Q: What mounting rail standard does the GL720E-2436-W-SQM6P use?
A: The GL720E-2436-W-SQM6P ships with M6 square-hole (3/8" sq.) vertical rails, which accept standard cage nuts and are compatible with the vast majority of modern server, switch, and patch panel equipment. The GL720E family also offers #10-32 threaded rails for legacy equipment — confirm your equipment's mounting standard before ordering.
Q: What door configuration does the GL720E-2436-W-SQM6P include?
A: It ships with a plexiglass (clear acrylic) front door and a solid PV rear door. The plexi front allows visual inspection of equipment status indicators without opening the door; the solid rear provides physical separation of cabling and rear-panel access from the room environment.
Q: Why is this enclosure available in Winter White instead of standard black?
A: Winter White is specified for environments where black enclosures are aesthetically or procedurally non-conforming — common in healthcare IT rooms, clean labs, broadcast control suites, and education facilities. The GL720E family is available in both Black and Winter White to match facilities requirements rather than defaulting to a single color.
Q: Is the GL720E-2436-W-SQM6P the right depth for full-size servers?
A: The 36" depth accommodates most enterprise full-depth servers. However, confirm your server's depth including rear cable egress before ordering. The GL720E family also comes in a 32" depth variant for shallower deployments — use 32" for primarily network and patch panel builds, 36" when hosting servers or deeper chassis.
Q: Can the GL720E-2436-W-SQM6P be used with Vertiv UPS and PDU accessories?
A: Yes. The GL720E enclosure is designed to be compatible with Vertiv's rack-mount UPS and PDU accessories. Standard vertical and horizontal PDUs sized for 36" depth enclosures mount in the rear without door interference. Consult Vertiv's accessory compatibility documentation for specific PDU mounting configurations.
The GL720E-2436-W-SQM6P lands in a specific procurement lane: 37U of capacity in a 24" footprint with a 36" deep interior and M6 square-hole rails — finished Winter White. That combination is not accidental. When a hospital IT director or a broadcast facility manager specifies a rack, the facilities and interior design teams often have final say on color, and black simply does not pass in those environments. This enclosure solves that without compromising on rack standard conformance.
Technical Highlights:
- 36" Interior Depth: The deeper of the two GL720E depth options — 32" and 36" — this configuration handles full-depth server chassis and leaves enough rear clearance for structured cable management without the rear door binding on cable bundles.
- Plexi Front / Solid PV Rear Door Pairing: The plexi front is a real operational benefit in low-staffing environments: a technician walking the room can visually confirm link lights and power states on a full cabinet of equipment in seconds without unlocking a single door. The solid PV rear adds a baseline physical access barrier on the termination side.
- M6 Square-Hole Rails: M6 cage-nut rails are stocked at virtually every facility and available same-day from local suppliers. Specifying this over a #10-32 threaded variant means maintenance teams will never be hunting for the right tap or thread insert — modern enterprise gear assumes M6, full stop.
Deployment Considerations:
- The 24" width fits standard EIA-310 equipment but will feel tighter than the 29" variant when routing dual power cords and patch cables simultaneously — plan your 1U cable management panels before the rack is populated, not after.
- Winter White finishes can show cable discoloration and dust accumulation more visibly than black. In high-traffic IT closets without controlled airflow, factor in cleaning frequency as part of your maintenance plan.
The GL720E-2436-W-SQM6P is the right call for healthcare IT closets, campus media production suites, and education data rooms where facilities approval on aesthetics is a hard gate and you still need a full 37U of standards-compliant rack capacity without moving to a 44U chassis.
