Chapter 2 Preparing for Installation
Safety
• 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 power company.
• Use only approved power cable(s). You have been provided with a power
cable for your GSS that is intended for its use (approved for use in your
country, based on the shipping location). Should you have to purchase a
power cable, ensure that it is 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 GSS, 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% of the rating.
• To help protect your GSS and components from sudden, transient increases
and decreases in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
• Do not modify power cables or plugs. Consult a licensed electrician or your
power company for site modifications. Always follow your local and national
wiring rules.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent
static damage, discharge static electricity from your body before you touch any of
your computer’s electronic components, such as the microprocessor. You can do
so by touching an unpainted metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted
metal surface to remove any static charge your body may have accumulated.
