Chapter 2 Safety and Site Requirements
General Site Requirements
Follow these guidelines when working on equipment powered by electricity:
•
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 from a circuit; always check the circuit.
•
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, proceed as follows:
–
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 if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
•
Use the ASA chassis within its marked electrical ratings and product usage instructions.
•
Install the ASA in compliance with local and national electrical codes as listed in the
Regulatory
Compliance and Safety Information for the Cisco ASA 5580 document
.
•
The ASA model equipped with AC-input power supplies are shipped with a 3-wire electrical cord
with a grounding-type plug that fits only a grounding-type power outlet. Do not circumvent this
safety feature. Equipment grounding should comply with local and national electrical codes.
Preventing Electrostatic Discharge Damage
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.
•
Always follow ESD-prevention procedures when removing and replacing components. Ensure that
the chassis is electrically connected to 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 antistatic strap, which should be between
1 and 10 megohms (Mohms).
General Site Requirements
