Regional Product Variants for Pakistan
Delivered across major data center hubs (Karachi, Lahore, Islamabad), the Gen 2 platform is available in three application-specific variants:
AR3157SPB2-Standard: The baseline high-density server cabinet featuring 48U space, 750mm width for side cable management pathways, and standard solid split side panels.
AR3157SPB2-HPC (High-Performance Computing): Enhanced with integrated toolless airflow blanking panels (1U/2U) and side-channel airflow management kits to maximize static pressure for AI training nodes.
AR3157SPB2-Net: Optimized for high-capacity networking deployments, configured with overhead cable troughs, partition roof bridges, and vertical/horizontal cable ladders to manage massive fiber/ethernet patch volumes.
Deployment, Installation, and Configuration
Pre-Deployment and Delivery
The enclosure features specialized ISTA 3E shock packaging. Logistics teams utilize the integrated, reusable unloading ramp to safely roll fully loaded or empty enclosures off transit pallets directly onto the server room floor, bypassing high-stress manual lifting.
Physical Installation
Baying & Alignment: Enclosures include built-in baying hardware to join multiple racks in a row (at 24-inch or 600mm centers).
Leveling & Grounding: Integrated leveling feet and casters allow rapid positioning. The system includes pre-installed, dedicated electrical grounding inserts connecting the roof, side panels, and front/rear doors directly to the frame.
Equipment Mounting: Adjusting the vertical EIA mounting rails is handled via a simple toolless design, accommodating varying equipment depths from 261.9 mm up to 914.9 mm.
Software and Hardware Configuration
Zero-U PDU Integration: Dual rear channels support toolless, vertical installation of APC NetShelter Advanced Gen 2 Rack PDUs (Switched, Metered, or Outlet-Metered variants) without consuming critical U-space.
Environmental Intelligence Setup: Integration of NetBotz environmental monitoring systems, including door switch sensors, spot fluid leak sensors, smoke detectors, and dry contact lines.
Airflow Optimization: Installation of external air sealing kits, modular blanking plates, and brush strip organizers to enforce a strict hot-aisle/cold-aisle containment architecture.
