Environmental Factors 

n 

Temperature 

The ambient temperature within an enclosure may be greater than room 

ambient temperature. Installation in an enclosure should be such that the 

amount of air flow required for safe operation is not compromised. 

Consideration should be given to the maximum rated ambient temperature. 

Overheating can cause a variety of problems, including premature aging and 

failure of chips or mechanical failure of devices. 

If the system has been exposed to abnormally cold temperatures, allow a 

two-hour warm-up period to bring it up to normal operating temperature before 

turning it on. Failure to do so may cause damage to internal components, 

particularly the hard disk drive. 

n 

Humidity 

High-humidity can cause moisture to enter and accumulate in the system. This 

moisture can cause corrosion of internal components and degrade such 

properties as electrical resistance and thermal conductivity. Extreme moisture 

buildup inside the system can result in electrical shorts, which can cause 

serious damage to the system. 

Buildings in which climate is controlled usually maintain an acceptable level of 

humidity for system equipment. However, if a system is located in an unusually 

humid location, a dehumidifier can be used to maintain the humidity within an 

acceptable range. Refer to the 

“Specifications” section of this user’s guide for 

the operating and storage humidity specifications. 

n 

Altitude 

Operating a system at a high altitude (low pressure) can cause electrical 

problems related to arcing and corona effects. This condition can also cause 

sealed components with internal pressure, such as electrolytic capacitors, to fail 

or perform at reduced efficiency.
