2 Install the Hardware Before installing the switch, verify that you meet these guidelines: • You have enough clearance to the front of the switch so you can read the light emitting diodes (LEDs). • The AC power cord reaches from the power outlet to the Utility panel connector. • The switch is rack-mounted before you power it up. • Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting. Ensure that the cabling is safely away from other devices that might damage the cables. If needed, allow one rack unit (RU) space between devices to provide room for cabling. • Airflow around the switch and through the vents is unrestricted. • Temperature around the unit does not exceed 113°F (45°C). If the switch is in a closed or multirack assembly, the temperature might be higher than normal room temperature. • Humidity around the switch does not exceed 95 percent while not in operation and 85 percent while operational. • Altitude at the installation site is below 10,000 feet. • The switch is installed in an environment as free as possible from dust and foreign conductive material (such as metal flakes from construction activities). Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing contaminant buildup inside the chassis, which can result in system malfunction.
