Contaminant Conditions; Checking Acoustic Noise Levels - Fujitsu ORACLE M10-1 Installation Manual

is stricter than the guidelines applied to indoor locations with more relaxed
environmental conditions such as general office environments. However, if the server
is installed in a server room, this condition is not difficult to meet because server
rooms utilize highly efficient moisture-proof materials and have fewer ventilation
cycles.
