Vertiv SA1-02003 2U Passive Rack Airflow Management Panel

Overview

The Vertiv SA1-02003 is a 2U passive SwitchAir blanking panel engineered to control airflow within standard 19-inch equipment racks. At 3.40 inches tall and 11.63 inches deep, the SA1-02003 fills open rack units where no active equipment is installed, preventing hot exhaust air from recirculating back into equipment intakes — a common cause of thermal runaway in dense deployments. If you're managing a rack with partial population or mixed-depth equipment, unmanaged open slots can undermine even a well-planned cooling architecture.

Key Features

• 2U form factor (3.40 in height): Fills two rack units in a single install, reducing the number of pieces needed to blank a partially populated rack compared to stacking 1U panels — fewer parts, faster commissioning.
• Standard 19-inch rack width: Fits any EIA-310-compliant 19-inch rack without adapters or modifications — compatible with the broad majority of data center, IDF, and security head-end enclosures.
• 11.63-inch depth: Provides meaningful coverage for mid-depth racks and two-post open frames where shallow blanks leave gaps at the rear of the rack cavity.
• Passive design: No power draw, no cabling, no configuration. Install once and it works — zero ongoing maintenance burden.

Integration & Compatibility

The SA1-02003 fits within the broader Vertiv SwitchAir family, which spans 1U through multi-U configurations to address different rack heights and depths. For racks requiring deeper coverage, the SA1-02005 (3.46 in tall, 26-in deep) or the SA1-03001 (5.21 in, 27.63-in deep) are alternatives within the same line. If you're outfitting a rack enclosure with a mix of populated and empty slots, pairing this panel with a structured rack cooling strategy will yield the most consistent thermal results.

Frequently Asked Questions

Q: What rack standard does the SA1-02003 fit?

A: The SA1-02003 is 19 inches wide, compatible with EIA-310-compliant 19-inch rack enclosures — the dominant standard in data center, IDF, and security head-end deployments.

Q: How many rack units does the SA1-02003 occupy?

A: It occupies 2U, with a measured height of 3.40 inches.

Q: Is the SA1-02003 active or passive?

A: Passive — no power, no cabling, no configuration required. It functions solely as a physical airflow barrier.

Q: What depth rack is the SA1-02003 suited for?

A: At 11.63 inches deep, it is well suited for mid-depth racks and two-post open frames. For deeper enclosures (24 in or more), consider longer variants in the SwitchAir family such as the SA1-02005 or SA1-03001.

Q: Can the SA1-02003 be used alongside active cooling equipment?

A: Yes. Passive blanking panels like the SA1-02003 complement active cooling by preventing hot-aisle air from bypassing the cooling units and recirculating into equipment intake zones.

The SA1-02003 is one of those parts that doesn't get specified until something goes wrong — and by then you're already dealing with throttled switches or a head-end NVR shutting down mid-shift. At 3.40 inches tall and 11.63 inches deep, this 2U passive panel covers the slot depth where most blanking failures actually occur: mid-depth racks where a 1U shallow blank leaves an open chimney at the rear half of the bay.

Technical Highlights:

• 2U height (3.40 in): Covers two rack units in a single piece — relevant when you're blanking several empty slots in a security head-end; fewer individual panels means faster installs on a crowded rack schedule.
• 19-inch width: Direct fit to any EIA-310 rack without shimming or custom hardware — no surprises on-site.
• 11.63-inch depth: Long enough to seal the rear gap in standard mid-depth two-post or four-post racks, where shorter panels leave an open bypass path for hot air.

Deployment Considerations:

• If your enclosure is 24 inches or deeper, the SA1-02003's 11.63-inch depth will leave a rear gap — size up to the SA1-02005 (26 in) or SA1-03001 (27.63 in) from the same SwitchAir line.
• Passive blanks provide no airflow assist — if you have a heavily loaded rack with poor natural airflow, blanking alone won't solve a thermal problem; pair with active cooling or rack fans as appropriate.

The SA1-02003 is the right call for security integrators populating 19-inch head-end racks in IDF closets and server rooms where equipment density is moderate and rack depth is 12–18 inches — exactly the profile where mid-depth blanking panels are chronically underspecified.
