Safety Guidelines
Follow these guidelines to ensure general safety:
Keep the chassis area clear and dust-free during and after installation.
Do not wear loose clothing or jewelry 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.
Disconnect all power by turning off the power and unplugging the power
cord before installing or removing a chassis or working near power supplies
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check the
circuit.
Operating Safety
Electrical equipment generates heat. Ambient air temperature may not be
adequate to cool equipment to acceptable operating temperatures without
adequate circulation. Be sure that the room in which you choose to operate
your system has adequate air circulation.
Ensure that the chassis cover is secure. The chassis design allows cooling
air to circulate effectively. An open chassis permits air leaks, which may
interrupt and redirect the flow of cooling air from internal components.
Electrostatic discharge (ESD) can damage equipment and impair electrical
circuitry. ESD damage occurs when electronic components are improperly
handled and can result in complete or intermittent failures. Be sure to follow
ESD-prevention procedures when removing and replacing components to
avoid these problems.
Wear an ESD-preventive wrist strap, ensuring that it makes good skin
contact. If no wrist strap is available, ground yourself by touching the
metal part of the chassis.
Periodically check the resistance value of the antistatic strap, which should
be between 1 and 10 megohms (Mohms).
LITHIUM BATTERY CAUTION:
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
