a. The width does not include the size of mounting ears.
l
b. The height is 1 U (1 U = 1.75 inches, or about 44.45 mm), which is a height unit defined in
International Electrotechnical Commission (IEC) 60297 standards.
l
c. Temperature and humidity are measured 1.5 m above the floor and 0.4 m in front of the rack when
no protection plate exists before or after the rack.
l
d. The short term operating conditions mean that the continuous operating period does not exceed 48
hours and the accumulative total period within a year does not exceed 15 days. If the continuous
operating period exceeds 48 hours or the total period within a year exceeds 15 days, it is regarded as
long term.
l
e. The ambient temperature change rate of a device with hard disk(s) is less than or equal to 20°C
per hour.
