To reduce the possibility of damage from electrostatic discharge, observe thefollowing precautions:v Limit your movement. Movement can cause static electricity to build up aroundyou.v The use of a grounding system is recommended. For example, wear anelectrostatic-discharge wrist strap, if one is available. Always use anelectrostatic-discharge wrist strap or other grounding system when working insidethe server with the power on.v Handle the device carefully, holding it by its edges or its frame.v Do not touch solder joints, pins, or exposed circuitry.v Do not leave the device where others can handle and damage it.v While the device is still in its static-protective package, touch it to an unpaintedmetal surface on the outside of the server for at least 2 seconds. This drainsstatic electricity from the package and from your body.v Remove the device from its package and install it directly into the server withoutsetting down the device. If it is necessary to set down the device, put it back intoits static-protective package. Do not place the device on the server cover or on ametal surface.v Take additional care when handling devices during cold weather. Heating reducesindoor humidity and increases static electricity.Internal cable routing and connectorsHard disk drive cable connectionThe following illustrations show the internal routing and connectors for theSAS/SATA signal cables.Notes:1.
