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.
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.
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.
–
The product does not operate correctly when you follow the operating instructions.
–
Use the correct external power source. Operate the product only from the type of power source
indicated on the electrical ratings label. If you are not sure of the type of power source required,
consult the Cisco Technical Assistance Center or a local electrician.
Use approved power cables only. You have been provided with one or more power cables with your
chassis power supply that are intended for use in your country, based on the shipping location.
Should you need to purchase additional power cables, ensure that they are rated for the product and
for the voltage and current marked on the product's electrical ratings label. The voltage and current
rating of the power cable should be greater than the ratings marked on the label.
To help prevent electrical shock, plug all power cables into properly grounded electrical outlets.
These power cables are equipped with three-prong plugs to help ensure proper grounding. Do not
use adapter plugs or remove the grounding prong from a power cable.
Observe power strip ratings. Make sure that the total current rating of all products that are plugged
into the power strip does not exceed 80 percent of the power strip rating.
Do not modify power cables or plugs yourself. Consult with a licensed electrician or your power
company for site modifications. Always follow your local and national wiring codes.
