Static Electricity Precautions

It is quite easy to inadvertently damage your PC, system board, components or devices even

before installing them in your system unit. Static electrical discharge can damage computer

components without causing any signs of physical damage. You must take extra care in han-

dling them to ensure against electrostatic build-up.

1. To prevent electrostatic build-up, leave the system board in its anti-static bag until you are

ready to install it.

2. Wear an antistatic wrist strap.

3. Do all preparation work on a static-free surface.

4. Hold the device only by its edges. Be careful not to touch any of the components, contacts

or connections.

5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or con-

nectors by their ends.

Safety Measures

To avoid damage to the system:

• Use the correct AC input voltage range.

To reduce the risk of electric shock:

• Unplug the power cord before removing the system chassis cover for installa-

tion or servicing. After installation or servicing, cover the system chassis before

plugging the power cord.

Important:

Electrostatic discharge (ESD) can damage your processor, disk drive and other com-

ponents. Perform the upgrade instruction procedures described at an ESD worksta-

tion only. If such a station is not available, you can provide some ESD protection by

wearing an antistatic wrist strap and attaching it to a metal part of the system chas-

sis. If a wrist strap is unavailable, establish and maintain contact with the system

chassis throughout any procedures requiring ESD protection.

Chassis Intrusion Connector

The board supports the chassis intrusion detection function. Connect the chassis intrusion

sensor cable from the chassis to this connector. When the system’s power is on and a chassis

intrusion occurred, an alarm will sound. When the system’s power is off and a chassis intrusion

occurred, the alarm will sound only when the system restarts.

MyGuard Hardware Monitor

Install the “MyGuard Hardware Monitor” utility. By default, the chassis intrusion detection func-

tion is disabled. When enabled, a warning message will appear when the chassis is open. The

utility can also be configured so that a beeping alarm will sound when the chassis is open.

Refer to the “MyGuard Hardware Monitor” section in chapter 4 for more information.
