Preparing for 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
Before working on equipment that is connected to power lines, remove jewelry (including rings,
Warning
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
Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury
Warning
and equipment damage. Statement 48
An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure
Warning
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
If a redundant power system (RPS) is not connected to the switch, install an RPS connector cover on
Warning
the back of the switch. Statement 265
