Preparing for Installation
Site Requirements
When determining where to place the switch, be sure to observe these requirements:
• Operating environment is within the ranges listed in Appendix A, “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.
• 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 or multirack assembly, 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. Make sure that the cabling is safely away from other devices that might damage
the cables.
• For sites requiring compliance to Telcordia GR-1089-CORE Intra-building Lightning requirements,
all 10/100 and 10/100/1000 ports must be connected with shielded cable grounded at both ends.
