Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
Disconnect all power and external cables before moving a chassis.
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected
at the network interface.
Use caution when installing or modifying telephone lines.
Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin
contact.
When removing or installing an ESD sensitive component, connect the equipment end of a
ground strap to an unpainted surface of the chassis, such as the chassis frame.
If you are returning a replaced part to the factory, immediately place it in a static shielding bag
to avoid ESD damage to the board.
The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing
can still cause damage.
For safety, periodically check the resistance value of the antistatic strap. The
