Safety
General Precautions
Observe the following general precautions when using and working with your AVS 3120:
• Keep your AVS 3120 components away from radiators and heat sources, and do not block cooling
vents.
• Do not spill food or liquids on your AVS 3120 components, and never operate the product in a wet
environment. If the AVS 3120 gets wet, see Chapter 4, “Troubleshooting the AVS 3120 Hardware”
or contact the Cisco Technical Assistance Center. For instructions on contacting the Technical
Assistance Center, see the “Obtaining Documentation” section on page xiv.
• Do not push any objects into the openings of your AVS 3120 components. Doing so can cause fire
or electric shock by shorting out interior components.
• Position cables and power cables carefully; route all cables and the power cable and plug so that they
cannot be stepped on or tripped over. Be sure that nothing rests on your AVS 3120 cables or the
power cable.
• Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local/national wiring rules.
• To help avoid possible damage to the system board, wait 5 seconds after turning off the AVS 3120
before removing a component from the system board or disconnecting a peripheral device from the
AVS 3120.
Maintaining Safety with Electricity
Follow these guidelines when working on equipment powered by electricity:
• Do not work alone if potentially hazardous conditions exist anywhere in your work space.
• Never assume that power is disconnected from a circuit; always check the circuit.
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
–
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 if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
