Product has been exposed to water.

Product has been dropped or damaged.

Product does not operate correctly when you follow the operating instructions.

Keep your system components away from radiators and heat sources. Also, do not block cooling 
vents.

Do not spill food or liquids on your system components, and never operate the product in a wet 
environment. 

Do not push any objects into the openings of your system components. Doing so can cause fire or 
electric shock by shorting out interior components.

Use the product only with other equipment approved by Cisco. 

Allow the product to cool before removing covers or touching internal components.

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 your service representative or local power company.

Use only approved power cables. If you have not been provided with a power cable for your system 
or for any AC-powered option intended for your system, purchase a power cable that is approved for 
use in your country. The power cable must be rated for the product and for the voltage and current 
marked on the electrical ratings label of the product. The voltage and current rating of the cable 
should be greater than the ratings marked on the product. 

To help prevent electric shock, plug the system components and peripheral power cables into 
properly grounded electrical outlets. These cables are equipped with three-prong plugs to help 
ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable.

Observe power strip ratings. Make sure that the total ampere rating of all products plugged into the 
power strip does not exceed 80 percent of the power strip ampere ratings limit.

Do not use appliance or voltage converters or kits sold for appliances with your product.

To help protect your system components from sudden, transient increases and decreases in electrical 
power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).

Position cables and power cords carefully; route cables and the power cord and plug so that they 
cannot be stepped on or tripped over. Be sure that nothing rests on your system components’ cables 
or power cord.

Do not modify power cables or plugs. Consult a licensed electrician or your power company for site 
modifications. Always follow your local or national wiring rules.
