Vertiv 8402E-29SM-B Split Round Mesh Door Enclosure Panel
Overview
The Vertiv 8402E-29SM-B is a split round mesh door panel designed to integrate with Vertiv E-Series ES DR rack enclosures. It accommodates cabinet heights of 79", 84", 91", and 98" and fits cabinet widths spanning 24" and the 29"/30"/32" range — giving data center architects flexibility across mixed-footprint deployments without sourcing separate door assemblies per cabinet height. The split design means you can open one half of the door independently, which matters in tight hot-aisle/cold-aisle rows where swinging a full-height door would block adjacent cabinets or containment curtains. Available in black (and other finishes), the 8402E-29SM-B is factory-new and sourced direct from the manufacturer.
Key Features
- Multi-height compatibility (79" / 84" / 91" / 98"): One door SKU spans the full height range of the E-Series ES DR cabinet line — eliminates the need to stock separate door assemblies for different rack heights across a deployment.
- Multi-width fit (24" and 29"/30"/32"): Covers both narrow and standard rack widths, so a single procurement covers mixed-width cabinet rows in the same data center zone.
- Split door design: Independent upper and lower panel operation lets technicians access cable management zones or patch panels without fully opening the enclosure — reduces disruption in live environments and works in tight row spacing where full door swing isn't possible.
- Round mesh perforation pattern: Mesh construction promotes passive airflow through the rear door panel, supporting hot-aisle exhaust without requiring a blanked rear that would trap heat inside the cabinet.
- Black finish: Standard black matches the E-Series ES DR cabinet aesthetic and suits both raised-floor data centers and modern open-floor colocation deployments.
Integration and Compatibility
The 8402E-29SM-B (often searched as 8402E 29SM B) is engineered for the Vertiv rack enclosure line, specifically the E-Series ES DR split-door cabinets. Before ordering, confirm your existing cabinet's height and width against the supported ranges above — this door panel is not a universal fit across all rack enclosures. If your deployment uses a 42U or non-standard height variant outside the listed range, verify compatibility with the cabinet model number directly. For data center infrastructure builds requiring full containment, pair this panel with compatible rack accessories such as blanking panels and cable managers from the same Vertiv E-Series line to maintain airflow integrity.
Frequently Asked Questions
Q: What cabinet heights does the 8402E-29SM-B support?
A: The 8402E-29SM-B is compatible with E-Series ES DR cabinets in 79", 84", 91", and 98" heights.
Q: What cabinet widths does this door panel fit?
A: It fits cabinets with widths of 24" and 29"/30"/32".
Q: What does the split door design mean in practice?
A: The split configuration means the door opens in two independent halves (upper and lower), allowing access to specific rack zones without fully opening the enclosure — useful in tight data center rows or active containment environments.
Q: Is this a replacement door or a component that ships with the cabinet?
A: The 8402E-29SM-B is sold as a standalone door panel for the Vertiv E-Series ES DR rack line. It can serve as a replacement or as an addition to an existing cabinet configuration.
Q: What color is this door panel?
A: The standard finish for this SKU is black, consistent with the E-Series ES DR cabinet aesthetic.
The 8402E-29SM-B addresses a specific pain point I see repeatedly in mixed-density data center rows: door swing clearance. The split design — upper and lower halves operating independently — means you can open the lower half to access patch panels or power strips in a live hot-aisle row without the door blade swinging into the aisle containment or an adjacent cabinet. That's not a theoretical benefit; it's the difference between a clean maintenance window and a containment breach.
Technical Highlights:
- Multi-height span (79"–98"): One SKU covers the full E-Series ES DR height range, which simplifies procurement and reduces spare-parts inventory when you're managing a mixed-height cabinet deployment across multiple rows or zones.
- Multi-width coverage (24" and 29"/30"/32"): Fits both narrow and standard rack widths under a single part number — useful when your floor plan mixes 24" network cabinets with 30" power-dense compute cabinets.
- Round mesh perforation: Rear mesh construction supports passive rear exhaust airflow, avoiding the heat buildup you get with a solid blanked rear door — relevant if you're running high-density compute without rear-mounted exhaust fans.
Deployment Considerations:
- Verify your specific cabinet model number against the E-Series ES DR line before ordering — the height and width ranges listed are broad, but not every Vertiv cabinet SKU in the field is part of this series.
- Evidence on hand covers height, width, and color only — load rating, hinge torque, and lock compatibility specs are not confirmed from available data; consult the Vertiv cabinet datasheet for your specific enclosure before spec'ing this door into a high-security or seismic-rated installation.
Best fit for data center operators standardizing on the Vertiv E-Series ES DR platform who need a field-replaceable or supplemental rear door that works across a mixed cabinet height/width environment without managing multiple door SKUs.
