• 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
