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.

Power Protection

The greatest threats to a system’s supply of power are power loss, power spikes,

and power surges caused by electrical storms, which interrupt system operation

and/or damage system components. To protect your system, always properly

ground power cables and one of the following devices.
