Wall-mount server rack for compact IT spaces

The APC AR118SM provides 18U of 19-inch rack space in a steel enclosure that mounts directly to a wall. It suits small offices, branch locations or edge deployments where floor-standing cabinets are impractical. The black finish matches standard network gear and the 348 lbs weight capacity supports dense equipment loads.

Integration into a wall-mounted build

The unit accepts standard 19-inch rack-mount servers, switches, patch panels and UPS modules without proprietary rails. Wall mounting frees valuable floor area and keeps cabling accessible from the front and sides. Installers must provide suitable wall fixings and verify the structure can carry the fully loaded weight.

Behaviour under sustained load

The welded steel frame maintains alignment when fully populated, preventing rail sag over long periods. Ventilation slots allow passive airflow through the cabinet, helping equipment stay within thermal limits during continuous operation. The fixed structure resists vibration from high-density drives or fan arrays without loosening.

Questions about this item

How much weight can the 18U steel frame hold before it reaches its limit?

The rack is rated for a maximum load of 348 lbs, so that is the ceiling for installed equipment.

Will the rack generate noticeable heat or noise when fully populated and running continuously?

The cabinet itself is passive steel with no fans or power supply, so it adds no audible noise or heat of its own.

What mounting hardware must I already have to secure this 19-inch wall-mount rack?

You will need suitable wall anchors or lag bolts for your wall type, plus 19-inch cage nuts or screws for the equipment rails.
