Safety Recommendations
Safety with Electricity
Follow these guidelines when working on equipment powered by electricity:
• Locate the emergency power-off switch in the room in which you are working. If an electrical
accident occurs, you can quickly turn off the power.
• Disconnect all power before doing the following:
–
Installing or removing a chassis
–
Working near power supplies
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
• Do not work alone if hazardous conditions exist.
• Never assume that power is disconnected from a circuit. Always check.
• Never open the enclosure of the router’s internal power supply.
• If an electrical accident occurs, proceed as follows:
–
Use caution; do not become a victim yourself.
–
Turn off power to the device.
–
If possible, send another person to get medical aid. Otherwise, assess the victim’s condition and
then call for help.
–
Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.

Statement 1004
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if
electronic printed circuit cards are improperly handled and can cause complete or intermittent failures.
Always follow ESD prevention procedures when removing and replacing modules:
• Ensure that the router chassis is electrically connected to earth ground.
• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to
an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To
guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
• If no wrist strap is available, ground yourself by touching a metal part of the chassis.
