Preface 1.3.1 When Using Your Computer System As you use your computer system, observe the following safety guidelines: Caution: Do not operate your computer system with any cover(s) (such as computer covers, bezels, filler brackets, and front-panel inserts) removed: • To help avoid damaging your computer, be sure the voltage selection switch on the power supply is set to match the alternating current (AC) 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 Japan, South Korea, and Taiwan - 230 V/50 Hz in most of Europe, the Middle East, and the Far East. Also be sure your monitor and attached peripherals are electrically rated to operate with the AC power available in your location. • To help avoid possible damage to the system board, wait five seconds after turning off the system before removing a component from the system board or disconnecting a peripheral device from the computer. • To help prevent electric shock, plug the computer and peripheral power cables into properly grounded power sources. These cables are equipped with 3-prong plugs to 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. • To help protect your computer system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply. • Be sure nothing rests on your computer system's cables and that the cables are not located where they can be stepped on or tripped over. • Do not spill food or liquids on your computer. If the computer gets wet, consult the documentation that came with it. • Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out interior components. • Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closedin wall unit or on a rug. 1.3.2 When Working Inside Your Computer Note: Do not attempt to service the computer system yourself, except as explained in this guide and elsewhere in Intel documentation. Always follow installation and service instructions closely. 1. Turn off your computer and any peripherals. 2. Disconnect your computer and peripherals from their power sources. Also disconnect any telephone or telecommunications lines from the computer. 3. Doing so reduces the potential for personal injury or shock. Also note these safety guidelines: • When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnect the cable. As you pull connectors apart, 8 Intel® Raid Controller SRCS28X User Manual
