Installation Guidelines
When determining where to place the switch, observe these guidelines.
• Before installing the switch, first verify that the switch is operational by powering it on and running
POST. Follow the procedures in the
“Verifying Switch Operation” section on page 2-4 .
• For 10/100 ports and the 10/100/1000 port, the cable length from a switch to an attached device
cannot exceed 328 feet (100 meters).
• For the 100BASE-FX port, the cable length from a switch to an attached device cannot exceed
6562 feet (2 kilometers).
• Operating environment is within the ranges listed in Appendix A, “Technical Specifications.”
• Clearance to front and rear panels meet these conditions:
– Front-panel LEDs can be easily read.
– Access to ports is sufficient for unrestricted cabling.
– Rear-panel AC power connector is within reach of an AC power outlet.
• Airflow around the switch and through the vents is unrestricted.
• Temperature around the unit does not exceed 113°F (45°C).
Note If the switch is installed in a closed area, such as a wiring closet, the temperature around it
might be greater than normal room temperature.
• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures.
