Chapter 2 Preparing for Installation
Safety
General Precautions
Observe the following general precautions when using and working with your system:
•
Keep your system components away from radiators and heat sources, and do not block cooling vents.
•
Do not spill food or liquids on your system components, and never operate the product in a wet
environment. If the computer gets wet, see the appropriate chapter in your troubleshooting guide or
contact the Cisco Technical Assistance Center. For instructions on contacting the Technical
Assistance Center, see
Obtaining Technical Assistance, page xviii
, in the Preface.
•
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.
•
Position system cables and power cables carefully; route system cables and the power cable and plug
so that no one will step on or trip over them. Be certain that nothing rests on your system
components’ cables or power cable.
•
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 regulations.
•
To help 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.
Maintaining Safety with Electricity
Follow these guidelines when working on equipment powered by electricity:
•
If any of the following conditions occurs, 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 certain 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 ACS SE
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 ACS SE, 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. Ensure 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, use a surge suppressor, line conditioner, or uninterruptable power supply (UPS).
