• Use caution; do not become a victim yourself.
• Disconnect power from the chassis.
• 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.
• Use the chassis within its marked electrical ratings and product usage instructions.
• The Cisco Content Security Appliance x95 Series are equipped with an AC-input power supply, which
is shipped with a three-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.
Prevent ESD Damage
ESD occurs when electronic components are improperly handled, and it can damage equipment and impair
electrical circuitry, which can result in intermittent or complete failure of your equipment.
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
See Hardware Specifications, on page 15 for information about physical specifications.
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
to acceptable operating temperatures without adequate circulation. Make sure that the room in which
you operate your system has adequate air circulation.
