Rack orientation and mounting
Racks must be mounted horizontally and must never be mounted
with the backplane flat on a horizontal panel or tabletop. This allows
airflow and ventilation through the racks. The Environmental
specifications provided in this guide apply only when using the
recommended mounting configuration.
Rack dimensions, including overall dimensions and patterns for
drilling holes for mounting, are provided in Rack dimensions section
and Rack orientation and mounting section.
