Safety Recommendations

Because any device that uses electricity must be handled carefully, follow these guidelines

to ensure general safety:

• Keep the area clear and dust-free during and after installation.

• Keep tools away from walk areas where you and others could trip over them.

• Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf

and roll up your sleeves.

• Wear safety glasses when 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.

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.

(To see translated versions of this warning, see the appendix “Translated Safety

Warnings”.)

• Locate the emergency power-off switch for the room in which you are working. Then,

if an electrical accident occurs, you can act quickly to shut off the power.

• Before working on the system, unplug the power cord.

• Disconnect all power before doing the following:

— Installing or removing the router

— Working near power supplies

• Do not work alone when potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit. Always check.

• Look carefully for possible hazards in your work area, such as moist ﬂoors, ungrounded

power extension cables, and missing safety grounds.
