Vertiv SA1-01002XLNB 1U Passive SwitchAir Airflow Management Panel

Overview

The Vertiv SA1-01002XLNB is a 1U passive airflow management panel purpose-built for deep network switches and storage appliances that exhaust hot air sideways into the rack instead of straight out the back. At 29 inches deep and 19 inches wide, the SA1-01002XLNB (often searched as SA1 01002XLNB) physically redirects that lateral exhaust toward the rear of the rack — keeping heat out of adjacent equipment and preserving the cold aisle/hot aisle separation your cooling infrastructure depends on. No fans, no power connection, no firmware: it installs in minutes and works continuously without maintenance.

Key Features

• 29-Inch Depth for Deep-Switch Compatibility: At 29 in deep, this panel reaches the full exhaust zone of enterprise-class core switches and high-density storage heads that standard 11–14 in panels can't cover. If your switch's lateral vents are positioned mid-chassis, a shorter panel leaves hot air spilling directly onto neighboring gear — this one closes that gap.
• 1U Height (1.88 in) — Minimal Rack Space Impact: Occupying just 1.88 in of rack height, the SA1-01002XLNB keeps your rack density high. A single U is a small price to pay to prevent thermal throttling or unplanned shutdowns on a six-figure switch.
• 19-Inch Standard Width — Universal Rack Fit: Designed for the industry-standard 19-in rack form factor, it drops into any EIA-310-compliant cabinet without adapter hardware or custom brackets.
• Passive Operation — Zero Power, Zero Noise, Zero Maintenance: No fans to fail, no power draw to budget, no firmware to patch. In environments where uptime accountability is measured in nines, passive components reduce the failure-mode count — a real operational advantage over active blanking alternatives.
• Complements Active Thermal Management: SwitchAir panels work alongside in-row coolers, hot-aisle containment systems, and perforated blanking panels to enforce airflow discipline at the rack level. Adding this directly above or below a laterally exhausting switch is the most targeted intervention available short of reconfiguring your entire cabinet layout.

Integration and Compatibility

The SA1-01002XLNB is designed for the Vertiv SwitchAir product family, which spans 1U through 9U form factors and depths from 5.75 in to 29 in — allowing you to match the panel depth to the specific switch model installed. For racks housing multiple switch generations or mixed-depth equipment, review the full rack cooling accessories lineup to pair the correct panel depth with each device. If your data center project requires a broader power and cooling strategy, blanking panels, cable management, and containment systems are complementary products worth specifying at the same time. Integrators designing network switch deployments in high-density racks should account for lateral exhaust at the specification stage — retrofitting airflow management after cabinet population is significantly more disruptive.

Frequently Asked Questions

Q: What makes the SA1-01002XLNB different from other SwitchAir models?

A: The SA1-01002XLNB has a 29-inch depth, which is the deepest 1U option in the SwitchAir line. This matches the chassis depth of enterprise core switches that exhaust air laterally mid-chassis — shorter panels (8.5 in to 14.63 in) won't reach those vent zones.

Q: Does the SA1-01002XLNB require power or any electrical connection?

A: No. It is a fully passive panel with no fans, no power supply, and no data connections. It installs mechanically in a standard 19-inch rack and requires no ongoing maintenance.

Q: What rack form factor does the SA1-01002XLNB fit?

A: It is built to the 19-inch EIA-310 standard, which is the universal rack width for data center and network equipment cabinets. It occupies 1U (1.88 inches) of vertical rack space.

Q: Can the SA1-01002XLNB be used in hot-aisle containment environments?

A: Yes — it is designed to work alongside containment systems, not to replace them. The panel redirects lateral switch exhaust toward the hot aisle, reinforcing the airflow discipline that containment systems depend on.

Q: Is there a version of this panel with side vents or a shorter depth?

A: Yes. The Vertiv SwitchAir line includes models from 5.75 inches to 29 inches in depth, in 1U, 2U, 3U, and 9U heights. The SA1-01002S (8.5 in depth) and SA1-01002L (14.63 in depth) are direct 1U siblings for shallower switch chassis.

Eden Phillips

The SA1-01002XLNB is the panel I reach for when a core switch has lateral exhaust ports sitting 15–25 inches back from the rack rail — a geometry that makes every standard-depth blanking panel useless. At 29 inches, this is the only 1U SwitchAir that fully covers those mid-chassis vents and actually pushes that hot air rearward rather than letting it recirculate into adjacent 1U devices.

Technical Highlights:

• 29-Inch Panel Depth: Covers the full lateral exhaust zone of deep enterprise switches — the only 1U SwitchAir option that reaches this far back in the cabinet.
• 1.88-In 1U Form Factor: Costs you exactly one rack unit. In a fully populated 42U cabinet, that is a trade worth making to prevent thermal events on switches that cost ten or twenty times more than this panel.
• Passive Architecture: Zero moving parts means zero wear-out mechanisms. In a rack you're not physically accessing for 18-month stretches, that reliability profile matters more than any active cooling spec.

Deployment Considerations:

• Measure your switch's lateral vent position before ordering — if the exhaust ports are within 14 inches of the front rail, the SA1-01002L may be sufficient and costs less. The 29-inch depth is specifically warranted for chassis where vents sit 15 inches or deeper.
• The SA1-01002XLNB is 1.88 inches tall, which is slightly taller than the 1.74-inch standard 1U siblings (SA1-01002S/SA1-01002L). Confirm your rack has genuine 1U clearance above and below the install position before committing.

This panel earns its place in high-density IDF closets and data center rows where deep Cisco Catalyst, Arista, or Juniper chassis exhaust laterally — environments where an unmanaged thermal plume is a reliability risk, not just an inefficiency.
