• Install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the
switch and control of the environment.
• Equipment that is placed too closely together or that is inadequately ventilated may cause system
over-temperature conditions, leading to premature component failure.
• Poor equipment placement can make chassis panels inaccessible and difficult to maintain.
• The switch requires a dry, clean, well-ventilated, and air-conditioned environment.
• To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the
intake air is too warm, an over-temperature condition may occur. The switch environmental monitor
may then shut down the system to protect the system components.
• Multiple switches can be rack mounted with little or no clearance above and below the chassis. However,
when mounting a switch in a rack with other equipment, or when placing it on the floor near other
equipment, ensure that the exhaust from other equipment does not blow into the air intake vent of the
switch chassis.
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
(40°C).
• 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
on the system remain unobstructed, especially the fan vent on the chassis.
• Clean the installation site at regular intervals to avoid buildup of dust and debris, which may 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 to normal operating temperature before turning it on.
Failure to observe these guidelines may damage the chassis' internal components.
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).
