Vertiv GL840CL-3036-3PF 3x14U Colocation Cabinet

Overview

The Vertiv GL840CL-3036-3PF is a 30-inch-wide, 36-inch-deep colocation cabinet configured in three 14U bays — a format purpose-built for shared-space data center environments where tenants require physically separated, individually lockable rack zones within a single cabinet footprint. If you're deploying shared rack infrastructure in a carrier-neutral colo facility or multi-tenant edge site, the three-bay architecture keeps tenants isolated without requiring three separate floor tiles. The GL840CL-3036-3PF (often searched as GL840CL 3036 3PF) is part of Vertiv's Geist-lineage cabinet portfolio and ships in black.

Key Features

• Three-Bay, 3×14U Architecture: Three discrete 14U compartments within one cabinet shell — each bay can be independently caged and keyed, which matters in colo environments where tenants share floor space but require physical access separation. Eliminates the overhead of managing three standalone cabinets while maintaining clear ownership boundaries.
• 30″ Width, 36″ Depth: The 30-inch width fits standard raised-floor tile spacing without consuming a full 600mm-wide footprint. The 36-inch depth accommodates mid-depth 1U/2U switching and server equipment; if your tenant gear runs deeper (full 1U switches with rear cable management), evaluate the 42-inch or 48-inch depth variants before committing.
• Multiple Door Configurations: Available with mesh front/rear, plexi front/solid rear (with two integrated fans), giving you airflow flexibility based on the thermal profile of the installed equipment. Mesh front and rear maximizes passive airflow for mixed or high-density loads. The solid rear with two integrated fans suits environments where hot-aisle/cold-aisle containment is needed but full mesh isn't viable.
• Integrated Fan Option on Solid Rear Door: The solid rear door variant ships with two fans already integrated — useful in partial-containment setups where you need directed airflow without a full active cooling deployment. Two fans won't replace a precision cooling unit for dense compute, but they handle light-to-moderate thermal loads in shared colo bays.
• Clear Bay Visibility Option: The 'Clear' bay configuration provides visual access to installed equipment without opening the door — useful for operations staff doing visual checks on indicator lights or cable status without requiring physical access or a key handoff to the tenant.

Integration and Compatibility

The GL840CL-3036-3PF is designed for standard EIA-310 rack-mount equipment. The three-bay layout is compatible with Vertiv's accessory ecosystem for colocation cabinets, including PDUs, cable management panels, and locking systems. Door selection (mesh, plexi, or solid with fans) should be finalized at order time based on your facility's containment strategy and the thermal density of planned tenant loads. For broader cabinet options within Vertiv's colocation line, review the Vertiv cabinet and enclosure catalog or explore the full data center cabinets category to compare depth and bay configurations side by side. If your deployment requires integrated power distribution, pair this cabinet with a rack-mount PDU matched to your tenant circuit requirements. For cable pathway planning into or out of the cabinet, reference the structured cable management category.

Frequently Asked Questions

Q: What are the available depth options for the GL840CL-3036-3PF?

A: The GL840CL series is available in 36-inch, 42-inch, and 48-inch depths. The GL840CL-3036-3PF specifically is the 36-inch-deep variant. If your installed equipment requires more rear clearance for cable dressing or deeper chassis, the 42-inch or 48-inch versions are the correct choice.

Q: How many U spaces does each bay provide?

A: Based on the product designation (3×14U), each of the three bays provides 14U of rack space for a total of 42U within the cabinet. This is the standard configuration for the GL840CL colocation format.

Q: What door options are available?

A: The GL840CL-3036-3PF is available with mesh front/rear doors or a plexi front with solid rear door. The solid rear door variant includes two integrated fans for directed airflow. Door type should be selected based on your containment strategy and thermal load per bay.

Q: Is the GL840CL-3036-3PF suitable for high-density compute deployments?

A: The two-fan solid rear door configuration handles light-to-moderate thermal loads in shared colo environments. For high-density blade or GPU compute requiring sustained airflow management, active precision cooling supplemented by the cabinet's airflow path is recommended — the integrated fans are not a replacement for a precision cooling unit.

Q: Can individual bays be independently locked for separate tenants?

A: The three-bay architecture is designed for colocation environments where physical access separation between tenants is required. Individual bay locking is the intended use case for this cabinet format. Verify specific locking hardware options with Vertiv's cabinet accessory line at order time.

The GL840CL-3036-3PF is one of those products where the spec that matters most is the one buyers overlook: the three-bay, 3×14U partitioned architecture. In a shared colo cage, you're not just stacking equipment — you're managing physical access rights for multiple tenants, and this cabinet's bay structure does that work at the enclosure level rather than through cage-within-cage workarounds.

Technical Highlights:

• 3×14U Bay Segmentation: Each 14U bay operates as an independently accessible zone — critical when SLA or contractual obligations require demonstrable physical separation between tenants in a shared cabinet.
• Depth Flexibility (36″/42″/48″): The 36-inch depth on this SKU suits networking and lighter 1U gear. The fact that 42-inch and 48-inch variants exist in the same family means you can standardize on the GL840CL form factor across a mixed-depth deployment without switching cabinet lines.
• Solid Rear Door with 2 Fans: Two integrated fans in the solid rear door option provide directed rear exhaust without requiring a hot-aisle containment build-out — practical for smaller colo deployments where full containment infrastructure isn't justified by the density.

Deployment Considerations:

• Door selection is a commit at order time — confirm your facility's airflow strategy (contained vs. open aisle) before specifying mesh vs. solid rear. Swapping doors post-install is possible but adds cost and downtime.
• The 36-inch depth is the limiting constraint here: rack-mount equipment with deep rear connectors, large cable bundles, or rear-mounted PDUs may be tight. Measure your deepest chassis before ruling out the 42-inch variant.

This cabinet is the right fit for carrier-neutral colo operators deploying shared-bay infrastructure for SMB tenants — the bay segmentation handles the access-control problem physically, which is simpler and more audit-friendly than software-based approaches for tenants without an IT team on-site.
