APC AR3357B2 APC NetShelter SX Server Rack Gen 2, 48U, 2258H x 750W x 1200D mm, without Doors, Black [TAA] AR3357B2X610

DATA SHEET: AR3357B2 NETSHELTER SX GEN 2 ENCLOSURE SERIES

The AR3357B2 series is the second-generation standard for high-density, high-capacity server rack enclosures. Specifically re-engineered for artificial intelligence (AI) compute clusters, high-density blade chassis, and hyper-converged architectures, the Gen 2 platform expands cooling ventilation and structural integrity over predecessor platforms.

All regional variants, localized structural configurations, turnkey deployment packages, engineering installations, and certified configurations are available exclusively through SKYRS in Pakistan.

PRODUCT OVERVIEW AND VARIANTS

The Gen 2 platform features an improved heavy-gauge steel 4-post framework built to isolate component heat and absorb extreme stationary loads. Possessing an expanded exterior footprint (750mm wide by 1200mm deep), it allows massive side-channel volume for dual-layer vertical power routing and structured fiber paths without restricting rear equipment exhaust.

Available Variants Managed Exclusively by SKYRS Pakistan:

• AR3357B2 Standard: The baseline 48U Gen 2 enclosure equipped with a black finish, split side panels, leveling feet, and pre-installed casters.

• AR3357W2 White: The specialized clean-room and high-visibility data center variant finished in brilliant white coat paint for optimized room reflectivity.

• AR3357B2-SP Shock Packaging: Engineered specifically for complete IT system pre-integration; equipped with heavy-duty shock-pallet stabilization, allowing systems to be populated and securely transported locally.

• AR3357B2-Aisle Ready: Structural pre-containment variant including top-of-rack brush entries, floor-baffle kits, and dual-door magnetic seals optimized directly for hot/cold aisle containment corridors.

DEPLOYMENT AND SITE INTEGRATION

Complete logistical handling, structural deployment, and building-level mobilization are handled directly by regional SKYRS engineering teams in Pakistan.

Site Pathway Validation: The massive 2258 mm height of the enclosure requires full vertical clearance confirmation across shipping docks, freight elevators, and data center entries prior to device roll-in.

Physical Mobilization and Positioning:

1. Ground Unboxing: Racks are safely unpalletized on low-profile ramps using non-marring tools to preserve structural panel coatings.

2. Row Positioning: Enclosures glide smoothly across clean-room environments using high-durability pre-installed casters.

3. Leveling Alignment: Integrated heavy-duty leveling feet are mechanically lowered to lock the rack permanently into position, shifting the load off the casters and correcting floor variance.

4. Baying Configuration: Racks aligned side-by-side are interconnected structurally using the integrated 270-degree (180-degree when bayed) door alignment pins and baying bracket sets.

5. Floor Securing: When handling high-density AI nodes, SKYRS employs heavy-duty bolt-down seismic sub-kits to fix the frame base into the concrete slab floor.

HARDWARE INSTALLATION

Rail Adjustment: The internal 4-post mounting rails have integrated depth indicators allowing effortless scaling for differing compute chassis lengths. Heavy blade chassis and multi-node nodes are positioned strictly at the lower U-sections to preserve low gravity indices.

Cable Routing: The 750 mm width provides dedicated vertical channels to comfortably isolate cabling arrays. Advanced Category 6A/8 cables or high-density fiber runs are fed alongside zero-U rear spaces with plastic D-rings to manage bend radiuses away from hot airflow output.

SYSTEM CONFIGURATION AND PROVISIONING

System tuning is performed on-site by certified SKYRS network engineers to optimize environmental and power pathways.

Thermal Control Adjustments: To sustain pressure differentials across server blades, toolless blanking panels are slotted into all unpopulated U-spaces. Cable cutouts utilize dense structural brush strips to prevent low-pressure hot air leakage.

Advanced Power and Sensor Configurations: Dual toolless vertical bays along the rear chassis support the deployment of Gen 2 Next-Gen Metered or Switched Rack PDUs. Monitoring infrastructures including sequential door switch kits, micro-vibration sensors, and liquid rope detectors are integrated into central management nodes for remote oversight.

AVAILABILITY NOTICE

Procurement Control: Supply chain procurement, physical deployment engineering, structural customization, and hardware optimization services for the Gen 2 AR3357B2 series are available within Pakistan exclusively via SKYRS. Systems are delivered with integrated vendor SLA coverage managed through centralized regional service offices.
