APC by Schneider Electric AR124SM 24U Wall-Mount Rack Enclosure Cabinet

Overview

The AR124SM is a 24U steel wall-mount rack enclosure from APC by Schneider Electric, built for installations where floor space is unavailable or impractical — server closets, telecom rooms, and security equipment bays where the rack must go on the wall rather than stand on the floor. At 45.5 in. (1,156 mm) in height and 176.4 lb (80 kg) shipping weight, this is a full-depth, full-strength unit: not a shallow patch-panel holder, but a cabinet sized to house a side-mounted UPS alongside active network and security equipment. The 19-in. wide rail standard means any standard rack-unit device drops straight in without adapter hardware.

Compatibility

Fits any 19-in. standard rack-mount equipment — network switches, NVRs, patch panels, KVM units, and APC rack-mount UPS models designed for side-mount or standard depth installation. The 24U capacity accommodates a mixed load typical in mid-size security head-end rooms: an NVR, one or two PoE switches, a patch panel, and a UPS in the same enclosure. The side-mount UPS depth designation indicates the cabinet's internal depth accommodates APC's deeper UPS chassis when oriented for side-mount; verify your specific UPS model dimensions against the interior usable depth before ordering.

Installation Notes

At 176.4 lb (80 kg) unloaded, wall-blocking and stud or concrete anchor selection are critical — consult a structural assessment before mounting. Steel construction provides the rigidity needed to hold full rack loading without flex, but also means the wall attachment points must be rated well above the combined cabinet-plus-equipment weight. Plan cable management runs before final wall placement; access to rear cable entry is significantly harder once the cabinet is wall-mounted and populated. Review rack enclosure mounting guidelines and the cable management options compatible with APC NetShelter-series cabinets before installation.
