Prevent Electrostatic Discharge Damage
• Install the ASA in compliance with local and national electrical codes as listed in the Regulatory
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.
Site Environment
You can place the chassis on a desktop, mount it on a wall, or on a rack shelf. 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.
Under no circumstances should you stack more than one chassis on top of one another. This disrupts

cooling air flow to the ASAs and causes damage to the hardware.

Hardware Specifications, on page 7
When planning the site layout and equipment locations, consider the information in the next section to help
avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently
experiencing shutdowns or unusually high error rates with your existing equipment, these considerations may
help you isolate the cause of failures and prevent future problems.
Site Considerations
Considering the following helps you plan an acceptable operating environment for the chassis, and avoid
environmentally caused equipment failures.
• Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment
• Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively
• Always follow the ESD-prevention procedures described previously to avoid damage to equipment.

to acceptable operating temperatures without adequate circulation. Ensure that the room in which you
operate your system has adequate air circulation.
within it. An open chassis allows air leaks, which may interrupt and redirect the flow of cooling air from
the internal components.
Damage from static discharge can cause immediate or intermittent equipment failure.
