Cisco VG410 - Safety with Electricity

• Wear safety glasses when working under conditions that might be hazardous to your eyes.
• Do not perform any action that may create a hazard to people, or which makes the equipment unsafe.
Safety With Electricity
Follow these guidelines when working on the equipment powered by electricity:
• Locate the emergency power-off switch in the room in which you are working. If an electrical accident
occurs, you can quickly turn off the power.
• Disconnect all the power source before you install or remove a chassis and before you work near power
supplies.
• Look carefully for possible hazards in your work area such as moist floors, ungrounded power extension
cables, frayed power cords, and missing safety grounds.
• Do not work alone if hazardous conditions exist.
• Never assume that the power is disconnected from a circuit. Always check.
• Never open the enclosure of the internal power supply.
• If an electrical accident occurs to another person, proceed as follows:
• Use caution; do not become a victim yourself.
• Turn off the power supply to the device.
• 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
actions.
In addition, use the following guidelines when working with any equipment that is disconnected from a power
source but has telephone wiring or other network cabling connections:
• Never install a telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for it.
• Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the
network interface.
• Use caution when installing or modifying telephone lines.
• Remove all the power cables from all the installed power supplies before opening the chassis.
Statement 1046—Installing or Replacing the Unit
To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be
made first and disconnected last.
If your unit has modules, secure them with the provided screws.
