Vertiv VRX-45U2436-B-SQM6 45U Adjustable-Depth Open Frame Server Rack
Overview
The Vertiv VRX-45U2436-B-SQM6 is a 45U, 24-inch wide open frame rack designed for data center, server room, and structured cabling deployments where equipment density and mounting flexibility matter. With adjustable depth from 24 to 36 inches and a factory-new black finish, this rack accommodates a broad range of 1U–4U servers, patch panels, switches, and power distribution units in a single vertical column — without committing to a fixed-depth enclosure before you know exactly what gear you are racking.

Key Features
- 45U Height: 45U of usable rack space translates to a high-density column — enough to house a full switching stack, patch panel field, and 1U server tier without stacking multiple racks or reconfiguring mid-deployment. If your headcount or equipment footprint grows, Vertiv offers 52U and 59U variants in the same VRX family for additional vertical capacity.
- 24–36in Adjustable Depth: The telescoping rail system adjusts from 24 to 36 inches, so you can fit compact edge-site gear or deeper 1U rack servers without swapping frames. This is the spec that prevents a premature purchasing decision when a mix of shallow and deep equipment is planned.
- M6 Threaded Mounting (3/8" Square Hole): The VRX-45U2436-B-SQM6 ships with M6 3/8" square-hole mounting rails — the current standard for most enterprise server and networking equipment. M6 cage nuts and screws seat securely without stripping, and the square-hole pattern is compatible with the vast majority of rack-mount switches, patch panels, and 1U servers shipping today.
- #12-24 Tapped Mounting Option: In addition to the M6 square-hole rail, the rack supports #12-24 tapped mounting — useful for legacy equipment or certain UPS and PDU form factors that ship with #12-24 screws rather than cage nuts. Having both patterns available in one frame avoids adapter kits and keeps installation straightforward.
- Black Finish: The black powder-coat matches standard data center aesthetics and reduces visual heat shimmer under high-bay lighting — a minor but practical benefit in open-floor installations where rack rows are visually inspected at a distance.
Integration and Compatibility
The VRX-45U2436-B-SQM6 is designed for use in standard 19-inch rack environments. The M6 3/8" square-hole rail pattern is compatible with the EIA-310 rack standard followed by the overwhelming majority of enterprise networking, server, storage, and rack-mount UPS equipment. The adjustable 24–36in depth accommodates both shallow top-of-rack switches and deeper storage nodes within the same frame. This rack is suitable for open-floor data center rows, server closets, or structured cabling infrastructure buildouts where a full enclosed cabinet is not required. Consult your equipment vendor specifications to confirm rail compatibility before ordering cage nut kits or sliding rail assemblies separately.
Frequently Asked Questions
Q: What mounting rail standard does the VRX-45U2436-B-SQM6 use?
A: The VRX-45U2436-B-SQM6 ships with M6 3/8" square-hole mounting rails, which are compatible with the EIA-310 standard used by most enterprise servers, switches, and rack-mount equipment. It also supports #12-24 tapped mounting for legacy hardware.
Q: What is the adjustable depth range on this rack?
A: The rack adjusts from 24 inches to 36 inches in depth, accommodating shallow networking gear and deeper server chassis without requiring a different frame.
Q: Is the VRX-45U2436-B-SQM6 available in other heights or colors?
A: Yes. The VRX rack family includes 52U and 59U height variants, and a Winter White color option is available in addition to the black finish of this model.
Q: Is this an open-frame rack or a fully enclosed cabinet?
A: This is an open-frame rack. It does not include side panels, doors, or a roof enclosure. If a fully enclosed cabinet is required for security or airflow management, Vertiv offers enclosed cabinet variants in the same product line.
Q: What is the rack unit count on the VRX-45U2436-B-SQM6?
A: The VRX-45U2436-B-SQM6 provides 45U of usable rack space, following the EIA-310 1.75-inch-per-U standard.
When I spec the VRX-45U2436-B-SQM6 for a customer, the first thing I point to is the 24–36in adjustable depth rail — that single feature eliminates most of the rack sizing errors I see on mixed-equipment deployments where someone locks in a fixed-depth frame before the switch and server purchase orders are finalized.
Technical Highlights:
- 45U Capacity: 45 rack units in a single frame is enough vertical space for a full access-layer switching stack, structured cabling patch field, and a small server tier — without splitting across two frames and adding inter-rack cabling runs.
- M6 Square-Hole Rails: The 3/8" M6 pattern is the current EIA-310 standard. This matters because sliding rail kits from Dell, HPE, Cisco, and most major vendors ship with M6 hardware by default — no adapter kits, no improvised solutions.
- #12-24 Tapped Rails: Legacy APC PDUs, older Cisco gear, and some KVM units still ship expecting tapped holes rather than cage nuts. Having both rail types available on the VRX-45U2436-B-SQM6 avoids a secondary hardware order mid-installation.
Deployment Considerations:
- This is an open-frame rack — plan for airflow management and physical security separately if the installation is in a shared or semi-public space. Blanking panels and a locking rack enclosure are separate line items.
- Confirm your heaviest equipment's rail kit compatibility against the 24–36in depth range before finalizing. Some 4U storage arrays ship with fixed-depth rail kits that only fit a narrow depth window.
The VRX-45U2436-B-SQM6 is the right frame for a controlled server room or data center floor row where open-frame access is an advantage — particularly during initial buildout phases where equipment is still arriving and rack layout is still being finalized.
