Installation Guidelines
Before installing the switch, these guidelines must be met:
•The operating environment must be within the ranges listed in Appendix A, “Technical Specifications.”
•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure that the cabling is away from other devices that might damage the cables.
•Airflow around the switch and through the vents must be unrestricted. We strongly recommend that you allow at least 3 in. (7.6 cm) of clearance from the left, right, and top sides of the switch to avoid any flow blockage. If you are installing the switch in a rack, allow at least 1.75 in.
(4 cm) of empty rack space above each switch.
