Preventing Electrostatic Discharge Damage; General Site Requirements; Site Environment - Cisco ASA 5512-X Hardware Installation Manual

Preparing for Installation

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 whether or not 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 document.

The ASA 5500-X models equipped with AC-input power supplies are shipped with a 3-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.

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 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 (Mohms).

General Site Requirements

The topics in this section describe the requirements your site must meet for safe installation and operation of your
system. Ensure that your site is properly prepared before beginning installation.

Site Environment

Place the chassis on a desktop, or mount it in a rack. The location of the chassis and the layout of the equipment
rack or wiring room are extremely important for proper system operation. Placing equipment too close together
with inadequate ventilation and inaccessible panels can cause system malfunctions and shutdowns. Improper
placement can also make it difficult for you to access the chassis for maintenance.
