Turn off your computer and any peripherals. 2. Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot openings at the back of the computer, before touching anything inside your computer. While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal components. 3. Disconnect your computer and peripherals from their power sources. Also, disconnect any telephone or telecommunication lines from the computer. Doing so reduces the potential for personal injury or shock. In addition, take note of these safety guidelines when appropriate: ‡ To avoid shorting out your computer when disconnecting a network cable, first unplug the cable from the network interface controller (NIC) on the back of your computer, and then from the network jack on the wall. When reconnecting a network cable to your computer, first plug the cable into the network jack, and then into the NIC. ‡ 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 disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure both connectors are correctly oriented and aligned. ‡ Handle components and cards with care. Don't touch the components or con- tacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its pins. &$87,21 7KHUH LV D GDQJHU RI D QHZ EDWWHU\ H[SORGLQJ LI LW LV LQFRUUHFWO\ LQVWDOOHG 5HSODFH WKH EDWWHU\ RQO\ ZLWK WKH VDPH RU HTXLYDOHQW W\SH UHFRP PHQGHG E\ WKH PDQXIDFWXUHU 'LVFDUG XVHG EDWWHULHV DFFRUGLQJ WR WKH PDQXIDFWXUHU·V LQVWUXFWLRQV 3URWHFWLQJ $JDLQVW (OHFWURVWDWLF 'LVFKDUJH Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer's electronic components, such as the microprocessor.You can do so by touching an unpainted metal surface on the computer chassis. As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated. 18 Setup and Quick Reference Guide
