Prevent Electrostatic Discharge Damage

Electrostatic discharge (ESD) occurs when electronic components are improperly handled, and it can
damage equipment and impair electrical circuitry, resulting in intermittent or complete failure.
Always follow ESD-prevention procedures when removing and replacing components. Ensure that the
chassis is electrically connected to an earth ground. Wear an ESD-preventive wrist strap, ensuring that
it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to
safely ground ESD voltages. To properly guard against ESD damage and shocks, the wrist strap and cord
must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the
chassis.
For safety, periodically check the resistance value of the anti-static strap, which should be between one
and 10 megohms.
Do not cover or block vents, or otherwise enclose the appliance.
Before beginning procedures that require access to the interior of the chassis, 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 turn off the power.
Do not work alone if potentially hazardous conditions exist anywhere in your work space.
Never assume that power is disconnected; always check.
Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
If an electrical accident occurs:
Use caution; do not become a victim yourself.
–
Disconnect power from the system.
–
If possible, send another person to get medical aid. Otherwise, assess the condition of the
–
victim, and then call for help.
Determine whether the person needs rescue breathing or external cardiac compressions; then
–
take appropriate action.
Use the chassis within its marked electrical ratings and product usage instructions.
The Firepower Management Center security appliances are equipped with an AC-input power
supply, which is shipped with a three-wire electrical cord with a grounding-type plug that fits into
a grounding-type power outlet only. Do not circumvent this safety feature. Equipment grounding
should comply with local and national electrical codes.
