12U 19-inch server cabinet

The APC NetShelter SX AR3103 is a 12U 19-inch rack cabinet designed to house standard-width network and server equipment. Its black finish suits professional environments. The unit provides a compact footprint for organised hardware deployment.

Ideal for small-scale rack builds

This cabinet suits installers who need a 12U enclosure for patch panels, switches or shallow servers. It is not for operators who require deeper cabinets for full-length servers, higher U counts for dense clusters, or integrated cooling accessories.
