Vertiv 8403E-SF29-B Split Fan Door for ES 84" Cabinets
Overview
The Vertiv 8403E-SF29-B is a split fan door designed for Vertiv ES series enclosures with an 84-inch cabinet height and a width range of 29 to 32 inches, finished in black. Split fan doors replace a standard solid or vented panel with an active airflow solution that integrates directly into the cabinet frame — keeping heat-sensitive equipment cooler without requiring a separate cooling unit. If you are building out a high-density network or server rack environment and need to manage front-to-back airflow at the door level, the Vertiv cabinet accessories line addresses that need with purpose-engineered components that mount to the existing enclosure without structural modification.
The 8403E-SF29-B (often searched as 8403E SF29 B) is sized specifically for the 84-inch tall ES cabinet footprint. That height corresponds to standard 42U and deeper enclosures common in data center rows and telecom equipment rooms. The 29-to-32-inch width range means this door fits the wider ES cabinet variants — important to verify against your specific enclosure model before ordering, since Vertiv publishes separate SKUs for 24-inch-wide cabinets and different height configurations.
Compatibility
This door is engineered for the Vertiv ES enclosure family. The supported cabinet dimensions are 84 inches tall and 29 to 32 inches wide. Vertiv publishes separate part numbers for other height and width combinations — the 48-inch, 79-inch, and 91-inch height variants, and the 24-inch width variant, all carry distinct model numbers. Do not assume cross-height or cross-width fit; verify your enclosure's exact external dimensions against Vertiv's cabinet accessory compatibility matrix before purchasing.
When integrating into a broader network cabinet and enclosure deployment, confirm that the door hinge orientation and latch style match your existing ES cabinet configuration. Split fan doors are also worth pairing with rack PDUs and structured airflow blanking panels to ensure the fan door's airflow contribution is not undermined by open rack units elsewhere in the enclosure.
Key Features
- 84-Inch Cabinet Height: fits the tall ES enclosure variant that houses 42U or more of equipment — the correct choice when your rack is already populated to full depth and you need a door swap rather than a full enclosure replacement.
- 29–32-Inch Width Range: accommodates the wider ES cabinet footprint used in higher-density rows where cable management and equipment depth demand extra internal clearance.
- Black Finish: matches standard Vertiv ES cabinet aesthetics, keeping mixed-accessory rows visually consistent — relevant when cabinet appearance is part of a customer-facing data center or network operations center.
- Split Door Design: the split configuration allows each door panel to be opened independently, which matters in tight rows where full-door swing clearance is not available.
Frequently Asked Questions
Q: What cabinet height does the 8403E-SF29-B fit?
A: The 8403E-SF29-B is designed for Vertiv ES cabinets with an 84-inch height. Other height variants (48", 79", 91") use separate Vertiv part numbers.
Q: What cabinet widths are compatible with this split fan door?
A: This door is sized for 29 to 32 inch wide ES cabinets. The 24-inch width variant is a separate SKU.
Q: Can the 8403E-SF29-B be installed on non-Vertiv enclosures?
A: This door is engineered specifically for the Vertiv ES enclosure family. Compatibility with third-party cabinets is not documented in Vertiv's published specifications and cannot be assumed.
Q: What color is the 8403E-SF29-B?
A: The door ships in black, matching standard Vertiv ES cabinet finishes.
Q: Is the split fan door sold as a pair or single panel?
A: The 8403E-SF29-B is a split door assembly — confirm quantity and panel configuration with Vertiv's accessory documentation for your specific enclosure before ordering.
The 8403E-SF29-B is a straightforward but easy-to-get-wrong purchase — the 84-inch height and 29-to-32-inch width specification exists because Vertiv ES cabinets ship in multiple footprint combinations, and the door assembly is not interchangeable across those variants. I have seen integrators order the wrong door on a data center buildout because they assumed all ES accessories are universal. They are not.
Technical Highlights:
- 84" Height Fit: targets the tall ES enclosure used in full-height rack rows — not the 48" or 79" variants, which require separate SKUs and have different door geometry.
- 29–32" Width Range: the wider ES cabinet footprint; the 24" narrow variant is a distinct part number — confirm your enclosure's external width before purchasing.
- Black Finish: matches standard Vertiv ES aesthetics — relevant when customer-facing data centers or NOC environments require visual consistency across mixed accessory configurations.
Deployment Considerations:
- Verify your ES enclosure's exact height and external width against Vertiv's cabinet accessory compatibility documentation before ordering — the model number encodes these dimensions, and returns on mismatched doors are avoidable with a two-minute check.
- A split fan door contributes active airflow only when the rest of the enclosure's blanking panel discipline is maintained — open 1U gaps elsewhere in the cabinet will short-circuit the thermal benefit.
Best fit for 84-inch ES enclosures in network equipment rooms or data center rows where row-level airflow management is being retrofitted without replacing the enclosure — the split configuration allows single-panel access in tight-aisle deployments where full door swing is not an option.
