Maintaining Your Site Environment

Temperature

Temperature extremes can cause a variety of problems, including premature aging and failure of chips or mechanical failure of appliances. Extreme temperature fluctuations can cause chips to become loose in their sockets and can cause expansion and contraction of disk drive platters, resulting in read or write data errors.

To minimize the negative effects of the temperature on system performance, follow these guidelines:

•Ensure that the system is operated in an environment that does not exceed 0 to 40ºC (32 to 104ºF) in either direction. The upper end of operating temperature above applies up to an altitude of 1,000 meters (3,281 feet) and then subtract 3ºC for each additional 1,000 meters up to a maximum operational altitude of 3,000 meters (9,843 feet).

•Ensure that the system has adequate ventilation. Do not place it within a closed-in wall unit or on top of cloth, which can act as insulation. Do not place it where it will receive direct sunlight, particularly in the afternoon. Do not place it next to a heat source of any kind, including heating vents during winter.

Adequate ventilation is particularly important at high altitudes. System performance may not be optimum when the system is operating at high temperatures as well as high altitudes.

•Make sure that all slots and openings on the system remain unobstructed, especially the fan vent on the back of the system.

•Clean the system at regular intervals to avoid any buildup of dust and debris, which can cause a system to overheat.

•If the system has been exposed to abnormally cold temperatures, allow a 2-hour warm-up period to bring it up to a normal operating temperature before turning it on. Failure to do so may cause damage to internal components, particularly the hard disk drives.

•If intermittent system failures are noticed, try reseating any socketed chips, which might have become loose because of temperature fluctuations.

Humidity

High-humidity conditions can cause moisture migration and penetration into the system. This moisture can cause corrosion of internal components and degradation of properties such 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.

Each system is rated to operate at 10 to 90 percent non-condensing relative humidity. Buildings in which climate is controlled by air conditioning in the warmer months and by heat during the colder months 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.

Altitude

Operating a system at high altitude (low pressure) reduces the efficiency of forced and convection cooling and can result in 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.
