DGS-1510 Series Gigabit Ethernet SmartPro Switch Hardware Installation Guide o 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South Korea and Taiwan o 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan o 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. • 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 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/national wiring rules. • When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe the following guidelines: o Install the power supply before connecting the power cable to the power supply. o Unplug the power cable before removing the power supply. o 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. CAUTION: Installing systems in a rack without the front and side stabilizers installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack. After installing system/components in a rack, never pull more than one component out of the rack on its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip over and may result in serious injury. vii
