Chapter 5 Maintaining Your GSS

Maintaining Your Site Environment

This section discusses various environmental factors that can adversely affect GSS performance and longevity. It covers:

Temperature

Humidity

Altitude

Dust and Particles

Corrosion

Electrostatic Discharge

Electromagnetic and Radio Frequency Interference

Magnetism

Power Source Interruptions

Temperature

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

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

Ensure that the GSS is operated in an environment no colder than 32°F (0°C) or hotter than 104°F (40°C).

Ensure that the GSS 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 in direct sunlight. Do not place it next to a heat source of any kind, including heating vents during winter.
