Chapter 1 Introduction
Environmental Tolerances and Safety Guidelines
• 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 DMP
or for any AC-powered option intended for your DMP, 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. If
you must use an extension cord, use a three-wire cord with properly grounded plugs.
• Observe extension cord and power strip ratings. Make sure that the total ampere rating of all
products plugged into the extension cord or power strip does not exceed 80 percent of the extension
cord or 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 a DMP. To prevent static damage, discharge static
electricity from your body before you touch any 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.
