– 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.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It may
occur if electronic printed circuit cards are improperly handled and may 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.
Caution: For the safety of your equipment, periodically check the resistance value of the
antistatic strap. It should be between 1 and 10 megohms (Mohm).
Warning!
IMPORTANT SAFETY INSTRUCTIONS
This warning symbol means danger. You are in a situation that could cause bodily injury.
Before you work on any equipment, be aware of the hazards involved with electrical circuitry
and be familiar with standard practices for preventing accidents. Use the statement number
provided at the end of each warning to locate its translation in the translated safety warnings
that accompanied this device.
SAVE THESE INSTRUCTIONS
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
