Installation Guidelines

When you determine where to place the switch, be sure to observe these requirements:

•For Ethernet ports, including the 10/100, the 10/100/1000 dual-purpose, and 1000BASE-T small form-factor pluggable (SFP) module ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).

•The cables meet the specifications in the “Cable and Adapter Specifications” section on page A-4. Each port must match the wave-length specifications on the other end of the cable, and the cable must not exceed the required cable length.

•Operating environment is within the ranges listed in Appendix B, “Technical Specifications.”

•Clearance to front and rear panels is such that

–Front-panel indicators can be easily read.

–Access to ports is sufficient for unrestricted cabling.

–Rear-panel power connector is within reach of an AC power receptacle.

•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.
