Prevent ESD Damage

• 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.

• The Cisco Content Security Appliance x95 Series are equipped with an AC-input power supply, which

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 17

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.

cables, frayed power cords, and missing safety grounds.

• 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.

power outlet only. Do not circumvent this safety feature. Equipment grounding should comply with local

and national electrical codes.
