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.
• Catalyst 3560CG-8PC-S, 2960C-8PC-L, 2960C-12PC-L, 3560C-8PC-S, and 3560C-12PC-S
switches: Allow at least 1.75 in. (4 cm) clearance from the ends of the external heat sink fins.
