Note: Rack units are large and heavy and are not easily moved. As maintenance activities require access
at both the front and the back, extra room is needed. The footprint illustration does not show the radius of
the swinging doors on the I/O rack. A service clearance of 915 mm (36 in.) needs to be maintained on
front, rear, and sides of the I/O rack.
