Temperature
Temperature extremes may cause a system to operate at reduced efficiency and cause a variety of problems,
including premature aging and failure of chips, and failure of mechanical devices. Extreme temperature
fluctuations may also cause chips to become loose in their sockets. Observe the following guidelines:
• Ensure that the system is operating in an environment no colder than 32°F (0°C) or no hotter than 104°F
• Ensure that the chassis has adequate ventilation.
• Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as insulation.
• Do not place the chassis where it will receive direct sunlight, particularly in the afternoon.
• Do not place the chassis next to a heat source of any kind, including heating vents.
• Adequate ventilation is particularly important at high altitudes. Make sure that all the slots and openings
• Clean the installation site at regular intervals to avoid buildup of dust and debris, which may cause a
• If the system has been exposed to abnormally cold temperatures, allow a 2-hour warm-up period to bring
Failure to observe these guidelines may damage the chassis' internal components.
Note The Catalyst 6880-X switches are equipped with internal air temperature sensors that trigger a minor alarm
at 104°F (40°C) and trigger a major alarm at 131°F (55°C).
