Operating Environment Requirements
You need to verify that your site meets all environmental and safety requirements. During the early planning
stages of installing or modifying your network, it is important that you develop a thorough understanding of
the regulations that pertain to your location and industry.
Temperature – The OS-10 system generates a specified amount of heat as indicated on the data sheet. It is
essential that you provide a temperature-controlled environment for both proper performance and safety.
Install the equipment only in a temperature- and humidity-controlled indoor area that is free of airborne mate-
rials that can conduct electricity.
The following are some general thermal recommendations for your wiring closet or equipment room:
• Ensure that the ventilation in the area is adequate to maintain a temperature below 50°C (122°F).
• Install a reliable air conditioning and ventilation system.
• Keep the ventilation in the wiring closet running during nonbusiness hours; otherwise, the equipment can
overheat.
• Maintain the following ambient operating temperature: 0° to 50° C (32° to 122°F)
• Maintain the following storage temperature: –40° to 70°C (–40° to 158°F)
Airflow requirements – To ensure proper airflow through the OS-10 equipment, follow these recommenda-
tions when you are installing your chassis:
• Leave 7.62 cm (3 inches) of minimum clearance on both the left and right sides of the chassis.
• Leave a half-rack unit (RU) of minimum clearance above and below the chassis for properairflow.
Note The OS-10 is a convection-cooled system, and adherence to these
clearance requirements is required for proper operation of the system.
Humidity – Keep the operating humidity between 5 and 95 percent relative humidity (noncondensing).
Table 4 summarizes the acceptable operational conditions for the OS-10 system.
