Allow the product to cool before removing covers or touching internal components.
Operate the product only from the type of external power source indicated on the electrical ratings label. If you
are not sure of the type of power source required, consult your service provider or local power company.
To help avoid damaging your system, be sure the voltage selection Switch (if provided) on the power supply is
set to match the power available at your location:
•
115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as
South Korea and Taiwan
•
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
•
230 V/50 Hz in most of Europe, the Middle East, and the Far East
Also be sure that attached devices are electrically rated to operate with the power available in your location.
Use only approved power cable(s). 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.
NOTE: A qualified electrician must perform all connections to DC power
and to safety grounds. All electrical wiring must comply with applicable
local or national codes and practices.
To help prevent electric shock, plug the system 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 cable, use a 3-wire cable with
properly grounded plugs.
Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged
into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension
cable or power strip.
To help protect your system from sudden, transient increases and decreases in electrical power, use a surge
suppressor, line conditioner, or uninterruptible power supply (UPS).
Position system cables and power cables carefully; route cables so that they cannot be stepped on or tripped over.
Be sure that nothing rests on any cables.
Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local/national wiring rules.
When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe
the following guidelines:
•
Install the power supply before connecting the power cable to the power supply.
•
Unplug the power cable before removing the power supply.
•
If the system has multiple sources of power, disconnect power from the system by unplugging ALL
power cables from the power supplies.
Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system. Avoid
sudden stops and uneven surfaces.
General Precautions for Rack-Mountable Products
Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation
accompanying the system and the rack for specific caution statements and procedures.
Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various
peripherals or supporting hardware.
