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 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 using
an extension cable is necessary, use a 3-wire cable with properly grounded plugs.
• Observe the 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 the 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 or national wiring rules.
When connecting or disconnecting power to and from hot-pluggable power supplies, 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 and ensure that all casters and stabilizers are firmly connected to the
system. Avoid sudden stops and uneven surfaces.
To help avoid damage to the system, be sure that the voltage selection switch, on the power supply,
is set to match the power available at the Switch’s location:
• 115V/60Hz is used mostly in North and South America as well as Far Eastern countries like as
South Korea and Taiwan
• 100V/50Hz is used mostly in Eastern Japan and 100V/60Hz in Western Japan
• 230V/50Hz is used mostly in Europe, the Middle East, Africa and the Far East
