Preparing for Installation Chapter 2 Switch Installation Warnings These warnings are translated into several languages in the Regulatory Compliance and Safety Information for the Catalyst 3750 Switch guide. 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 Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place. Statement 156 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 Attach only the following Cisco RPS model to the RPS receptacle: PWR-RPS2300, PWR675-AC-RPS-N1=. Statement 370 Warning When the Catalyst 3750-12S switch and 100BASE-FX MMF small form-factor pluggable (SFP) module (model number GLC-GE-100FX) are running, the surface temperature of the removed SFP module might be hot.
