#1: Dimensions of the rack fixture are not included.
#2: Dimensions for the handles of the Switch, fan unit, and power supply unit are
included.
#3: The power cable supplied with the Switch supports only 100 V AC.
#4: The value is measured at 1 m from the side of the Switch. The number of
rotations of the fan varies according to the intake temperature. Because of this, the
value of the noise changes.
#5: According to JIS Z 8813 Measuring Methods for Suspended Particulate Matter
Concentration in Air.
#6: No condensation
