Chapter 2 Installing and Starting Up the Switch Preparing for Installation Warning To prevent the switch from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 113°F (45°C). To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings. Warning The device is designed to work with TN power systems. Warning When installing the unit, the ground connection must always be made first and disconnected last. Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 16A international) is used on the phase conductors (all current-carrying conductors). Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. Warning Care must be given to connecting units to the supply circuit so that wiring is not overloaded. Warning Unplug the power cord before you work on a system that does not have an on/off switch. Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. 78-6456-03 Catalyst 3500 Series XL Hardware Installation Guide 2-3
