To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the precautions in this section.
Observe the following general precautions for using and working with your system:
•Observe and follow service markings. Do not service any Cisco product except as explained in your system documentation. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to electrical shock. Components inside these compartments should be serviced only by an authorized service technician.
•If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or contact your authorized service provider:
–The power cable or plug is damaged.
–An object has fallen into the product.
–The product has been exposed to water.
–The product has been dropped or damaged.
–The 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 Cisco-approved equipment.
•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 product's electrical ratings label. 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.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside the device. To prevent static damage, discharge static electricity from your body before you touch any of your system's electronic components. You can do so by touching an unpainted metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
•When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
•When transporting a sensitive component, first place it in an antistatic container or packaging.
•Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
Rack Installation Safety Guidelines
Before installing your device in a rack, review the following guidelines:
•Two or more people are required to install the device in a rack.
•Ensure that the room air temperature is below 95°F (35°C).
•Do not block any air vents; usually 6 inches (15 cm) of space provides proper airflow.
•Plan the device installation starting from the bottom of the rack.
•Install the heaviest device in the bottom of the rack.
•Do not extend more than one device out of the rack at the same time.
•Remove the rack doors and side panels to provide easier access during installation.
•Connect the device to a properly grounded outlet.
•Do not overload the power outlet when installing multiple devices in the rack.
•Do not place any object weighing more than 110 lb (50 kg) on top of rack-mounted devices.
