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.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):

To avoid possible damage to the system board, wait 5 seconds after turning off the system before
removing a component from the system board or disconnecting a peripheral device from the
computer.
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.
The product has been dropped or damaged.
–
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 power company.
Use only approved power cable(s). You have been provided with a power cable for your MARS
Appliance that is intended for your system (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 MARS Appliance, 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 system and components from sudden, transient increases and decreases in
electrical power, Cisco recommends the use an uninterruptable power supply (UPS) for your MARS
Appliances.
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.
