Prevent ESD Damage
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
• Do not work alone if potentially hazardous conditions exist anywhere in your work space.
• Never assume that power is disconnected; always check.
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension
• If an electrical accident occurs:
• Use the chassis within its marked electrical ratings and product usage instructions.
Prevent ESD Damage
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 antistatic 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.
Warning
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.

• 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 the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
