APC AR3157 is an industry standard server rack ready for medium to high density environments with height designed to easily fit through standard doorways. Wide rack design allows for additional space beside the vertical mounting rails for passing cabling from front-to-back in the enclosure. Width is ideal for converged and hyper-converged IT which include a mix of server, storage, and network switches all in one rack. 48U height allows for an additional 6U of rack mounting space maximizing u-space per rack footprint.
