Seawater (salt damage) Do not install out at sea or within 500 m
(1,640.4 ft.) of the seashore.
(However, this does not apply if air
conditioning facilities do not use outside air.)
when the relative humidity falls below 30%. The set optimal relative humidity range
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.
2.5.3 Contaminant conditions
Table 2-6 lists the acceptable reference values for contaminants with regard to the
SPARC M10 systems.
2.6 Checking Acoustic Noise Levels
This section describes the acoustic noise levels of the SPARC M10 systems.
The acoustic noise levels of each chassis in Table 2-7 and Table 2-8 were measured
according to the following conditions.
Measurement environment: Complying with ISO 7779
Ambient temperature: 23°C
