Environmental Factors

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.
◆
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.
◆
Altitude
Operating a system at a high altitude (low pressure) reduces the efficiency of the cooling fans to cool the system.
This 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.
