Site Preparation
When determining where to place the switch, ensure the following conditions are met:
• Operating environment is within the temperature, humidity, and altitude ranges listed in
Appendix A, “Technical Specifications.”
If the switch is installed in a closed or multirack assembly, the temperature might be
greater than normal room temperature.
• Airflow around the switch and through the vents is unrestricted.
• Cables (such as Category 3, 4, or 5 straight-through or crossover cables and fiber-optic
cables) are at hand to connect the switch to the other devices in your network.
• Cable distances from the switch to network equipment and workstations are within the
limits described in Appendix B, “Connectors and Cables.”
• Clearance to front and rear panels is such that:
— Front-panel indicators can be easily read.
— Access to the front- and rear-panel ports and connectors is sufficient for connecting
cables.
— Rear-panel power connectors are within reach of power sources.
• Cabling is away from sources of electrical noise, such as radios, power lines, and
fluorescent lighting fixtures.
