Installation Guidelines
Before installing the switch, verify that these guidelines are met:
• For Ethernet ports, including the 10/100, the 10/100/1000 dual-purpose, and 1000BASE-T SFP
module ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).
• For cable requirements for SFP module connections, see the “Cable Pinouts” section on page B-6.
• Operating environment is within the ranges listed in Appendix A, “Technical Specifications.”
• Front-panel indicators can be easily read, and access to ports is sufficient for unrestricted cabling.
• AC-power cord reaches from the power outlet to the connector.
• 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.
Note If the switch is installed in a closed or multirack assembly, the temperature around it might be
greater than normal room temperature.
• Before you connect the switch to a power source, note the power consumption specifications in
Appendix A, “Technical Specifications.”
