Q. What are the best practices for mounting the fanless switches in closets, under tables, or in other closed environments?
A. Be sure that the temperature around the unit does not exceed its maximum limit. Switches can operate at 122°F (50°C) for short time periods only. Best practices allow for at least 3 inches (7.6 cm) of clearance on all sides and ventilation openings and at least 1.75 inches (4 cm) of clearance above each switch if placed in a rack. Access to ports should be sufficient for unrestricted cabling. The rear-panel power connector should be within reach of an AC power receptacle. When wall-mounting the switch, have the switch align with ports facing down. For more information about best installation practices, see the Cisco Catalyst 1000 Series Switches Hardware Installation Guide.
