Vertiv SA1-01002L Passive 1U Rack Airflow Director
Overview
The Vertiv SA1-01002L is a passive 1U SwitchAir designed to redirect and manage airflow around network switches and other rack-mounted equipment in standard 19-inch enclosures. At 1.74 inches tall and 14.63 inches deep, it occupies a single rack unit while extending far enough to channel exhaust air away from adjacent gear — a straightforward, no-power solution for racks where hot-spot problems trace back to recirculating exhaust rather than insufficient cooling capacity. If you're seeing elevated inlet temperatures on switches sitting above or below high-wattage equipment, a passive airflow director like the SA1-01002L is often the lowest-cost first step before adding active cooling.
Key Features
- 1U Form Factor (1.74 in tall): Occupies exactly one rack unit — no wasted U-space in dense switch stacks where every slot matters. Pairs cleanly with 1U switches without consuming additional space budget.
- 19-Inch Rack Width: Fits standard EIA-310 19-inch two-post and four-post racks without modification. No custom brackets or adapters required for typical data center or IDF deployments.
- 14.63-Inch Depth: The SA1-01002L (often searched as SA1 01002L) runs deeper than the short SA1-01002S (8.5 in) but shorter than the extra-long XLNB variant (29 in), making it the mid-reach option in the SwitchAir 1U line — appropriate for mid-depth switches where shorter panels leave a gap and longer panels create installation conflicts with cable management.
- Passive Operation: No power connection, no fans, no firmware — nothing to fail, nothing to configure. Once installed, airflow management is continuous and maintenance-free.
- Family Depth Options: The SwitchAir line spans multiple depths (8.5 in, 11.63 in, 14.63 in, 29 in at 1U) and heights up to 9U, so you can match the panel to the actual switch depth rather than compromising on coverage.
Integration and Compatibility
The SA1-01002L is designed for standard 19-inch rack enclosures. Verify your rack's usable depth and the switch depth it will sit behind before ordering — the 14.63-inch depth is the defining spec for this SKU. For shallower switches or two-post open-frame racks with limited rear clearance, the SA1-01002S at 8.5 inches may be the better fit. For deep chassis switches (blade systems, modular aggregation switches), the SA1-01002XLNB at 29 inches provides full rear coverage.
Frequently Asked Questions
Q: What is the depth of the SA1-01002L, and how does it compare to other SwitchAir 1U models?
A: The SA1-01002L is 14.63 inches deep. Within the 1U SwitchAir family, the SA1-01002S is 8.5 inches, the SA1-01002 is 11.63 inches, and the SA1-01002XLNB is 29 inches. Choose based on the depth of the switch it will cover.
Q: Does the SA1-01002L require any power or active components?
A: No. The SA1-01002L is a fully passive device with no power connection, fans, or electronics. It manages airflow mechanically and requires no configuration or maintenance once installed.
Q: Will the SA1-01002L fit in a standard 19-inch rack?
A: Yes. The SA1-01002L is 19 inches wide, designed for standard EIA-310 19-inch two-post and four-post rack enclosures.
Q: How many rack units does the SA1-01002L occupy?
A: The SA1-01002L occupies 1U (1.74 inches tall), leaving the rest of your rack space available for active equipment.
Q: Is the SA1-01002L the right choice for deep modular switches?
A: At 14.63 inches, the SA1-01002L covers mid-depth switch chassis. For deep modular or blade switches requiring 29 inches of rear coverage, the SA1-01002XLNB is the appropriate model in the SwitchAir 1U family.
The SA1-01002L lands in the middle of Vertiv's 1U SwitchAir depth range at 14.63 inches — that specific measurement is what makes it the right call for mid-depth access-layer switches (typically 12–16 inches) where the short 8.5-inch SA1-01002S leaves a gap behind the chassis and you end up with recirculated hot exhaust re-entering the switch's front intake.
Technical Highlights:
- 14.63-Inch Depth: Covers the rear of mid-depth 1U switches without extending past the rear of a standard 24-inch-deep rack — avoids cable management conflicts that the 29-inch XLNB variant can create in shallower enclosures.
- 1U Height (1.74 in): Slots directly between switches in a dense 1U stack without consuming additional rack units — critical in fully populated IDFs where space is already constrained.
- 19-Inch Width: Standard rack mount across the full SwitchAir line — no model-specific brackets needed, which simplifies procurement when deploying across multiple rack sizes in a single facility.
Deployment Considerations:
- Measure your switch chassis depth before ordering — the SA1-01002L at 14.63 inches is designed for mid-depth equipment; going too short leaves a hot-air bypass gap, going too long creates rear-cable interference.
- This is a passive product with no mounting hardware specified in the evidence — confirm rack compatibility (two-post vs. four-post, rail type) with Vertiv documentation before ordering for non-standard enclosures.
The SA1-01002L is best suited for IDF closets and campus network rooms running mid-depth 1U access switches in fully populated racks, where recirculating exhaust is a documented problem and an active cooling upgrade is not justifiable on budget or space grounds.
