Operating temperature and humidity ranges may vary depending on the installed mass storage
devices. High humidity levels can cause improper disk operation. Low humidity levels can
aggravate static electricity problems and cause excessive wear of the disk surface.
Temperature, humidity, and sound power levels are provided in
Table 2-5
while minimum,
maximum, and typical configurations are in
Table 2-6 (page 40)
and
Table 2-7 (page 41)
.
NOTE:
De-rate maximum dry bulb temperature 1 degree/300 meters (1000 feet) above 900
meters 3000 feet).
