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.

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.

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.

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.
