Electrical Equipment Guidelines

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. Statement 4
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
OL-5916-01
Keep the chassis area clear and dust-free during and after installation.
If removing the chassis cover, put the removed chassis cover in a safe place.
Keep tools away from walk areas where you and others could fall over them.
Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught
in the chassis. Fasten your tie or scarf and roll up your sleeves.
Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
The installation of the router should be in compliance with national and local electrical codes. In the
United States, National Fire Protection Association (NFPA) 70, United States National Electrical
Code. In Canada, Canadian Electrical Code, part I, CC22.1. In other countries, International
Electrotechnical Commission (IEC) 364, part 1 through part 7.
Never attempt to lift an object that might be too heavy for you to lift by yourself.
Always turn all power supplies off (O) and unplug all power cables before opening the chassis.
Always unplug the power cable before installing or removing a chassis.
The AC-powered routers ship with a three-wire electrical grounding-type plug, which only fits into
a grounding-type power outlet. This is a safety feature. The equipment grounding should be in
accordance with local and national electrical codes.
