Environmental Requirements
Note:
Although the SL8500 library will function over a full list of
environmental ranges as specified below,
optimal reliability
is achieved
if the environment is maintained between the recommended ranges.
Important:
Although this equipment is designed to operate in environmental
conditions of 20% to 80% humidity, industry best practices recommends
computer rooms maintain a relative humidity of 40% to 50% for best
performance.

Table 41. Environmental Definitions
British thermal unit
(Btu)
A measure of the amount of heat required to raise the temperature of one
pound of water one degree Fahrenheit. British thermal units are most
commonly associated with power over a unit of time—Btu per hour (Btu/hr).
Relative Humidity
A measure of water vapor in the air.
Temperature
The measurement of hot and cold to specific scales, such as Celsius (also
called centigrade) and Fahrenheit.
The Celsius temperature scale uses 0° for the freezing point of water and 100°
for the boiling point of water. The Fahrenheit temperature scale uses 32° for the
freezing point and 212° for the boiling point.
Watt
A watt is a unit of power or the amount of energy per unit of time. Often the term
watt is used for expressing energy consumption as kW (kilo-Watts).
Wet bulb
The difference in temperature between wet bulb (humidity) and dry bulb
(temperature) provides a measure of atmospheric humidity.
