APC by Schneider Electric AR7304 NetShelter SX Side Panel Set, Black
Overview
The AR7304 is a replacement and add-on side panel set designed specifically for APC NetShelter SX enclosures. At 38.03 inches (96.6 cm) in height and built from 18-gauge steel, these panels provide the structural closure and cable-containment discipline that open-frame or partially-configured racks lack. If you've deployed a APC by Schneider Electric NetShelter SX cabinet without side panels — or you're replacing damaged panels after a physical move or expansion — the AR7304 delivers a factory-matched fit in matte black without requiring the full enclosure SKU.
Weighing 32.08 lb (14.55 kg) as a set, these are solid steel closures, not decorative trim. They contribute meaningfully to airflow containment when paired with blanking panels and structured cabling — a real consideration in hot-aisle/cold-aisle data center rows or server closets where uncontrolled bypass air undermines cooling efficiency.
Key Features
- 18-Gauge Steel Construction: Thicker than the sheet metal used on many competitive enclosures — panels resist flex under load and won't bow when you're routing cables behind them or leaning equipment against the rack. For permanent installations, this matters more than it sounds during a panel swap at 2 AM.
- 96.6 cm (38.03 in) Panel Height: Matched to the NetShelter SX enclosure height — no cutting, no shimming, no gap at the top or bottom that would break your hot-aisle containment seal. Exact OEM fit means airflow performance stays predictable.
- Non-Rack-Mountable Mounting Mode: These panels attach directly to the enclosure frame, not to rack rails — installation doesn't consume rack unit space. You retain full usable U-space inside the cabinet while closing off the sides completely.
- Matte Black Finish: Matches standard NetShelter SX aesthetics — relevant when cabinets are customer-visible in colocation suites, executive server rooms, or edge deployments where the rack row appearance is part of the site's professional presentation.
- 32.08 lb Set Weight: Substantial enough to confirm steel (not composite) construction; manageable for a two-person install without lift equipment. Factor this into shipping and handling when ordering multiple sets for a rack row buildout.
- Designed for Airflow Containment: Closing the sides of a NetShelter SX converts an open or semi-open cabinet into a properly sealed enclosure, supporting structured hot/cold aisle separation and reducing recirculation — a measurable cooling efficiency gain in dense deployments.
Integration & Compatibility
The AR7304 is engineered for the APC NetShelter SX enclosure family. Before ordering, confirm your existing cabinet SKU against the network cabinet and enclosure compatibility list — NetShelter SX comes in multiple widths (600mm and 750mm) and depths, and side panels are dimension-specific. Pairing these with proper rack blanking panels and a structured power distribution layout completes the airflow management picture. This panel set does not include top, bottom, or door components — if your project requires a full enclosure rebuild, evaluate whether a complete cabinet SKU is more cost-effective than sourcing panels individually.
Frequently Asked Questions
Q: What enclosure family is the AR7304 designed for?
A: The AR7304 is designed for APC NetShelter SX enclosures. Confirm your specific cabinet model's width and depth before ordering, as side panels are dimension-matched to particular SX configurations.
Q: Are these panels rack-mountable inside the cabinet?
A: No. The AR7304 panels mount directly to the enclosure frame exterior and do not consume any rack unit (U) space inside the cabinet.
Q: What gauge steel are these panels made from?
A: The AR7304 uses 18-gauge steel, providing a rigid, non-flexing closure suitable for permanent data center and server room installations.
Q: What is the panel height?
A: Each panel measures 38.03 inches (96.6 cm) in height, matched to the corresponding NetShelter SX enclosure height.
Q: Do the AR7304 panels help with airflow management?
A: Yes. Closing the sides of a NetShelter SX enclosure with these panels supports hot-aisle/cold-aisle containment by preventing bypass air from entering or escaping around the cabinet sides — a measurable cooling benefit in structured data center rows.
Q: What color are the AR7304 panels?
A: Matte black, matching the standard NetShelter SX enclosure finish.
I specify the AR7304 when a customer has already deployed NetShelter SX cabinets open-sided — either because the panels shipped damaged, were removed for an upgrade, or were never ordered in the first place. At 18-gauge steel and 32.08 lb per set, these aren't cosmetic covers; they're structural closures that complete the enclosure's airflow management design.
Technical Highlights:
- 18-Gauge Steel: Heavier than the 20-gauge sheet used on economy cabinets — panels stay flat under sustained pressure and don't develop the mid-span bow that causes gaps in hot-aisle containment curtain interfaces.
- 38.03 in (96.6 cm) Height: OEM-matched to the NetShelter SX frame — no field modification required, and the top-to-bottom seal is consistent across the full panel face.
- Non-Rail-Mount Design: Attaches to the enclosure frame directly, preserving every U of usable rack space — a detail that matters when the cabinet is already loaded to 80–90% capacity.
Deployment Considerations:
- Confirm the specific NetShelter SX width (600mm vs. 750mm) and depth variant before ordering — side panels are not universally interchangeable across the SX family, and an incorrect fit will leave gaps that defeat airflow containment.
- At 32.08 lb for the set, plan for two-person installation, particularly in live environments where the adjacent cabinet row is already powered — awkward single-person maneuvering of a heavy steel panel in a tight hot aisle is a recipe for an incident.
The AR7304 is the right call for any NetShelter SX deployment in a structured data center row where hot-aisle/cold-aisle containment is in use — particularly colocation environments where an open-sided cabinet is a lease-compliance issue or a trigger for cooling surcharges from the facility operator.
