Server rack APC NetShelter SX Gen 2 45U, 2124H x 600W x 1200D mm, freestanding, with sides, black

APC NetShelter SX Gen 2 45U is a freestanding server rack designed for 19" equipment, offering external dimensions of 2124H x 600W x 1200D mm and supplied side panels. The cabinet provides a secure, enclosed environment for data center or server room installations, with a key lock, adjustable leveling feet and a black finish. The redesign increases load capacity and usable space to support higher-density computing and modern IT deployments.

Advantages

The Gen 2 NetShelter SX improves load capacity and airflow compared with previous generations, supports high-density server and networking equipment, and includes features that simplify cable management and equipment access. Its 270° door opening (180° bayed) and 80% perforated front door support better aisle clearance and airflow for high-powered servers. The all-steel construction and recyclable packaging contribute to long service life and reduced environmental impact.

Suitable for

• High-density server racks and AI compute nodes
• Network and telecommunication equipment in colocation or enterprise racks
• Data center cabinets and secure server room installations
• Environments requiring organized cable management and easy equipment access

When it may not be suitable

This freestanding 45U cabinet is large and heavy (approx. 137.8 kg), so it may not be suitable for small offices with limited floor space or locations where floor loading and transport are constrained. If you need a compact, wall-mounted, or shallower cabinet for space-limited installations, consider smaller or alternative enclosures.

What to consider before purchase

• Available floor space and floor load capacity where the cabinet will be installed
• Depth and width of the planned equipment to ensure compatibility with 600 x 1200 mm external dimensions
• Required airflow and cooling arrangements for high-density servers
• Access needs for cabling and maintenance (aisle clearance and door swing)
• Transport and installation logistics given the cabinet weight

Usage recommendations

For best results, plan equipment layout to balance load front-to-back, reserve proper airflow clearances, and use APC cable management and rack accessories to maintain cooling efficiency and serviceability in colocation or enterprise environments.
