Introduction

SY-5EHM/5EH5

1-2 HANDLING THE MAINBOARD

To avoid damage to your mainboard, follow these simple rules while unpacking:

ØBefore handling the mainboard, ground yourself by grasping an unpainted portion of the system's metal chassis.

ØRemove the mainboard from its anti-static packaging. Hold the mainboard by the edges and avoid touching its components.

ØCheck the mainboard for damage. If any chip appears loose, press carefully to seat it firmly in its socket.

Warning: Do not apply power if the mainboard appears damaged. If there is damage to the board, contact your dealer immediately.

1-3 ELECTROSTATIC DISCHARGE PRECAUTIONS

Make sure to ground yourself before handling the mainboard or other system components. Electrostatic discharge can easily damage the components. Note that you must take special precautions when handling the mainboard in dry or air-conditioned environment.

To protect your equipment from electrostatic discharge, take the following precautions:

ØDo not remove the anti-static packaging until you are ready to install.

ØGround yourself before removing any system component from its protective anti-static packaging. (To ground yourself, grasp the expansion slot covers or other unpainted portions of the computer chassis.)

ØFrequently ground yourself while working or use a grounding strap.
