APC AR7711X960 – Zero‑U Rear PDU Mount Bracket

Overview :

APC AR7711X960 is a rear‑facing PDU mounting bracket designed for use in APC NetShelter SX enclosures. It is deployed by network and data center engineers to mount rack power distribution units (PDUs) behind the rack’s primary equipment plane. This addresses the need to conserve vertical rack space while maintaining accessibility and cable organization in medium‑to‑large cabinets.

The bracket kit supports rear installation of PDUs in racks with 750 mm interior width at heights of 42U or 48U. The zero‑U design ensures that critical front‑accessible rack units remain available for servers, switches, or compute gear. Bracket dimensions are approximately 3.31 in height, 4.45 in width, and 2.09 in depth with a lightweight form factor (~0.23 kg).

This accessory integrates into the rear channel and vertical flanges of NetShelter SX cabinets. It is positioned in the data center or IDF/MDF rack environment, enabling managed placement of PDUs where cable routing and airflow are critical. Rear orientation facilitates cleaner power cord pathways and reduces clutter behind active equipment.

Compatibility is specific to 750 mm wide NetShelter SX enclosures at standard 42U or 48U heights. The bracket does not house electrical components — its purpose is mechanical mounting support for PDUs in the rear of the rack, aligning with standard EIA‑310 frame spacing.

A practical deployment example is in a high‑density rack where dual side‑mounted PDUs are repositioned to the rear to free front U‑space for network appliances and blade servers. This setup enhances cable management by aligning PDU receptacles parallel to cabling infrastructure.

This kit is not suitable as a standalone PDU, nor does it provide structural support for non‑PDU hardware outside the specified NetShelter SX mounting system. It should be excluded in racks narrower than 750 mm or in systems without compatible rear accessory channels.

• Designed for 750 mm wide NetShelter SX racks

• Supports both 42U and 48U rack heights
