When determining where to install the switch, ensure that these guidelines are met.

• Clearance to the switch front and rear panels meet these conditions.

  • Front-panel LEDs can be easily read.

  • Access to ports is sufficient for unrestricted cabling.

  • AC power cord can reach from the AC power outlet to the connector on the switch rear panel.

  • The pluggable transceiver module minimum-bend radius and connector length is met. See the Cisco pluggable transceiver module documentation for more information.

• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.

• Airflow around the switch and through the vents is unrestricted.

• For copper connections on Ethernet ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).

• Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.

• Humidity around the switch does not exceed 95 percent.

• Altitude at the installation site is not greater than 10,000 feet.

• 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. You must install this equipment in an environment free from dust and foreign conductive or corrosive materials. For more information, see Air Quality and Corrosion.
