Preparing for Installation

Warnings

These warnings are translated into several languages in the Regulatory Compliance and Safety Information for the Catalyst 3750 Switch document that ships with the switch.

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. Statement 17B

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Statement 43

Warning Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and equipment damage. Statement 48

Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. Statement 122

Warning Ethernet cables must be shielded when used in a central office environment. Statement 171

Warning If a redundant power system (RPS) is not connected to the switch, install an RPS connector cover on the back of the switch. Statement 265

Warning To comply with safety regulations, mount switches on a wall with the front panel facing up. Statement 266

Warning Attach only the following Cisco RPS model to the RPS receptacle:

PWR-RPS2300, PWR675-AC-RPS-N1=. Statement 370

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Warning Read the installation instructions before connecting the system to the power source. Statement 1004
