airflow, and ventilation. Make sure that the AC power cord can reach the power connector on thefront panel of a power supply unit from the power outlet.• Airflow: On the C9010, airflow is from the right to the left side as you face the switch. Hot air isexpelled from the left side. Ensure that airflow around the switch and through the side vents isunobstructed and that hot exhaust is not used as air intake on the right side.• Temperature: The ambient temperature around the operating switch should not exceed 113°F (45°C).If the switch is in a closed or multi-rack assembly, the temperature might be higher than normal roomtemperature.• Cabling: Route the cabling to avoid sources of electrical noise, such as radio transmitters, broadcastamplifiers, power lines, and fluorescent lighting fixtures. Make sure that the cabling is safely away fromother devices that might damage the cables. If needed, allow 1 RU between devices to provide roomfor cabling.• Altitude: Altitude at the installation site is below 10,000 feet (3048 m).• Humidity: The relative humidity around the operating switch is between 5% and 95% (non-condensing) with 91°F (33°C) maximum dew point.• Dust: Install the switch in an environment as free as possible from dust and foreign conductivematerial (such as metal flakes from construction activities). Cooling mechanisms, such as fans in theswitch, can draw dust and other particles inside the chassis, which can result in system malfunction.C9010 Hardware Description 7
