Maintaining Safety with Electricity
When working on electrical equipment, follow these guidelines:
• 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 before working on it.
• Look carefully for possible hazards in your work area, such as damp floors, ungrounded power extension
cables, frayed or damaged power cords, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
• Use extreme caution; do not become a victim yourself.
• Disconnect power from the system.
• Seek medical attention, if necessary.
• Use the product within its marked electrical ratings and product usage instructions.
• Install the product in compliance with local and national electrical codes.
• If any of the following conditions occur, contact the Cisco Technical Assistance Center:
• The power cable or plug is damaged.
• An object has fallen into the product.
• The product has been exposed to water or other liquids.
• The product has been dropped or shows signs of damage.
