APC Netshelter SX GEN 2 High Strength Rack 52U 2436H X 750W X 1295D MM with - AR9558SPB2

APC by Schneider Electric AR9558SPB2 NetShelter SX Gen 2 52U High-Strength Freestanding Rack

Overview

The AR9558SPB2 is APC's 52U server and network rack enclosure from the NetShelter SX Gen 2 family — a freestanding, black steel cabinet sized at 2436H × 750W × 1295D mm. At 52U, it gives you enough vertical real estate to house a full-density compute stack, a security NVR tier, patch panels, and PDUs in a single footprint without stacking cabinets. The 750 mm width is the standard data center lane width, compatible with raised floor tile spacing and hot-aisle/cold-aisle containment systems. If you're planning a network video recorder room, edge compute closet, or enterprise IDF/MDF buildout, the AR9558SPB2 is sized for serious density.

Key Features

• 52U Capacity: 52 rack units of usable vertical space — enough to mount high-density server blades, NVR appliances, patch panels, and power distribution in a single cabinet. Eliminates the cost and cable management burden of splitting a deployment across two partial-height racks.
• 750 mm Width: The standard 750 mm external width fits raised-floor grid spacing and integrates cleanly into hot-aisle/cold-aisle containment rows. Side panels are included, giving you a fully enclosed cabinet rather than an open-frame skeleton.
• 1295 mm Depth: 1295 mm total depth accommodates full-depth servers, redundant PSU tails, and rear cable management channels. The adjustable mounting depth ranges from 292 mm (min) to 1143 mm (max), so shallow 1U/2U appliances and full-depth 4-post servers both mount without adapters.
• Adjustable Mounting Rails — 292 to 1143 mm: The 851 mm span of rail adjustment means you can install a thin 1U switch at the front and a full-depth 4-post server in the same cabinet without adding rail extension kits. That's a real asset in mixed-purpose security and IT closets where equipment depths vary widely.
• EIA-310E Certified: The EIA-310E certification confirms the cabinet meets the Electronics Industry Alliance standard for rack dimensions and hole patterns — your equipment vendor's rail kits will fit without shimming or custom drilling. Cross-brand compatibility is guaranteed at the standard.
• UL 2416 Listed: UL 2416 is the UL standard specifically for rack and cabinet enclosures. Listing under this standard means the structure, materials, and construction have been independently tested for safety — relevant if your facility requires UL-listed infrastructure for insurance or code compliance.
• High-Strength Construction: The "High Strength" designation in the NetShelter SX Gen 2 line indicates a reinforced frame spec above the standard SX Gen 2. Dense NVR configurations with multiple large-capacity drives, or blade chassis with full drive sleds, push cabinet weight significantly — a reinforced frame matters when you're spec'ing against a static load budget.
• 5-Year Manufacturer Warranty: APC covers the AR9558SPB2 with a 5-year manufacturer warranty — longer than the typical 1–3 year coverage on commodity rack enclosures, which matters for a passive infrastructure component that's expected to outlive multiple equipment refresh cycles.

Integration & Compatibility

The AR9558SPB2 integrates into the broader APC by Schneider Electric ecosystem: APC's NetShelter accessory line (blanking panels, brush strips, cable management arms, vertical cable managers, and airflow guidance kits) is designed to fit this cabinet natively. EIA-310E certification means all major server and network equipment manufacturers' standard rail kits — from Dell, HPE, Cisco, and others — will install per their documented instructions. The 750 mm width supports APC's InfraStruXure row-based containment products. For power distribution, APC's rack PDU lineup mounts directly to the vertical mounting channels. If you're deploying alongside PoE switches or patch infrastructure in a security operations room, the depth and rail adjustability accommodate both shallow network switches and deeper server nodes in the same enclosure.

Frequently Asked Questions

Q: What is the usable rack space in the AR9558SPB2?

A: The AR9558SPB2 provides 52U of usable rack space. At the standard 1.75 inches (44.45 mm) per rack unit, that gives you approximately 91 inches of vertical mounting height for equipment.

Q: What is the mounting depth range on the AR9558SPB2?

A: The adjustable mounting rails span from a minimum of 292 mm (29.2 cm) to a maximum of 1143 mm (114.3 cm), accommodating shallow 1U appliances through full-depth servers without additional rail extension hardware.

Q: Is the AR9558SPB2 EIA-310E certified?

A: Yes. The AR9558SPB2 is certified to EIA-310E, the Electronics Industry Alliance standard for rack enclosures. This ensures compatibility with standard equipment rail kits from all major server and networking vendors.

Q: What certifications does the AR9558SPB2 carry?

A: The AR9558SPB2 is certified to EIA-310E and listed under UL 2416 (the UL standard for rack and cabinet enclosures).

Q: What is the warranty on the AR9558SPB2?

A: APC covers the AR9558SPB2 with a 5-year manufacturer warranty.

Q: Does the AR9558SPB2 include side panels?

A: Yes. The product name explicitly states "With Sides" — the AR9558SPB2 ships as a fully enclosed cabinet with side panels included, not as an open-frame enclosure.

James Everett

The AR9558SPB2 is one of the more practical spec decisions you can make when designing a high-density physical security or enterprise IT closet. The 851 mm of rail adjustment — running from 292 mm min to 1143 mm max — is what separates this from budget enclosures where you're shimming rails or bolting in adapters every time equipment depths don't align. In practice, that range handles shallow patch panels, mid-depth managed switches, and full-depth NVR appliances in the same column.

Technical Highlights:

• 52U / 2436 mm Height: At 2436 mm tall, this cabinet is just under the standard 2438 mm ceiling clearance threshold in most data center facilities — it clears raised-floor environments cleanly while delivering a full 52U of usable density.
• EIA-310E + UL 2416: Dual certification means both dimensional interoperability (standard rail kits fit on day one) and independently tested structural integrity — relevant for any facility with insurance or code requirements on listed infrastructure.
• 750 mm Width with Sides: The fully enclosed 750 mm footprint integrates with APC's InfraStruXure containment rows and standard raised-floor tile grids. Side panels are included — you're not buying a stripped frame and sourcing panels separately.

Deployment Considerations:

• The 39 kg shipping weight (package dims: 1105W × 1460D × 2670H mm) means you'll want two-person or mechanical lift for final positioning — plan the delivery path before the unit arrives on site, particularly through fire doors and into elevator-constrained server rooms.
• The "High Strength" designation adds frame rigidity, but static load specs are not confirmed in available evidence — verify the rated static load against your planned equipment weight before final configuration, especially for dense blade chassis or multi-drive NVR tiers.

For a physical security operations room deploying multiple NVR appliances, network switches, patch panels, and UPS infrastructure in a single row, the AR9558SPB2's depth clearance, rail flexibility, and enclosed form factor make it the right spec — particularly where a 5-year warranty horizon aligns with your equipment refresh cycle.
