Server rack APC NetShelter SX Gen 2 45U, 2124H x 750W x 1070D mm, black, with sides

Freestanding APC NetShelter SX Gen 2 45U server rack in black provides 45U of usable rack space within external dimensions of 2124H x 750W x 1070D mm. Designed for server room and data center deployments, the enclosure is constructed from all-steel materials, includes removable side panels for access and cable routing, adjustable feet for leveling, and a keyed lock for basic physical security. The redesign improves load capacity, airflow and internal organization while maintaining a modern, customer-facing appearance suitable for colocation or on-premises IT rooms.

Advantages

The NetShelter SX Gen 2 supports higher-density configurations and increased maximum load capacity, enabling installation of heavier server and network equipment without compromising stability. Improved door perforation and enclosure airflow characteristics help maintain thermal performance for high-power servers. Removable side panels and rear access simplify cable management and equipment servicing, while adjustable feet and a keyed front lock provide stable placement and controlled access. The enclosure is compatible with a broad range of APC accessories for power distribution, thermal management and cabling.

Suitable for (tasks / use cases)

• Data center and server room rack installations

How to use

Place the freestanding rack on a suitable, level surface and adjust the leveling feet to achieve stable placement. Remove side panels or open doors to route power and network cabling before mounting equipment. Install servers and other 19-inch rack-mount devices into the 45U rail space using appropriate cage nuts or mounting hardware, and position heavy items lower in the rack to maintain stability. Use compatible APC accessories—such as PDUs, cable management panels and blanking panels—to organize power distribution, airflow and cable runs. Secure doors with the keyed lock where controlled access is required.

Usage recommendations

Use the NetShelter SX Gen 2 rack with APC or industry-standard rack accessories to optimize cooling and cable management. Maintain clearance in front and behind the rack for airflow and service access, position heavier equipment toward the bottom of the rack to preserve stability, and verify floor weight limits when installing heavy loads. For higher-density or high-power deployments, combine perforated doors with appropriate room cooling and PDUs sized to the expected power draw.
