Users Manual Part 1

To install Mac Pro into a rack, you need to attach the rail assemblies to Mac Pro and the rack.
The minimum depth of the rack must be at least 24 inches; the maximum depth should be no
more than 42 inches.
Note: Mac Pro requires five rack units (5U). The top two units should be left vacant, the rail
assemblies should be installed in the next two units, and one unit below the rail assemblies
should be left vacant.
Air to cool Mac Pro flows from front to back. Make sure nothing blocks any of the openings in the
front and back of the housing.
