• 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.
• 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.
Rack Mounting of Systems
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.
