Chapter 2 Preparing for Installation
Safety Recommendations
• 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 adaptive security appliance chassis within its marked electrical ratings and product usage
instructions.
• Install the adaptive security appliance in compliance with local and national electrical codes as listed
in the Regulatory Compliance and Safety Information for the Cisco ASA 5500 Series document.
• The adaptive security appliance models 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.
• The adaptive security appliance models equipped with DC-input power supplies must be terminated
with the DC input wiring on a DC source capable of supplying at least 15 amps. A 15-amp circuit
breaker is required at the 48 VDC facility power source. An easily accessible disconnect device
should be incorporated into the facility wiring. Be sure to connect the grounding wire conduit to a
solid earth ground. We recommend that you use a closed loop ring to terminate the ground conductor
at the ground stud. The DC return connection to this system is to remain isolated from the system
frame and chassis.
Other DC power guidelines are listed in the Regulatory Compliance and Safety Information for the
Cisco ASA 5500 Series document.
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).
