FCC and DOC Statement on Class B

This equipment has been tested and found to comply with the limits for a Class B

digital device, pursuant to Part 15 of the FCC rules. These limits are designed to

provide reasonable protection against harmful interference when the equipment

is operated in a residential installation. This equipment generates, uses and can

radiate radio frequency energy and, if not installed and used in accordance with

the instruction manual, may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or televi-

sion reception, which can be determined by turning the equipment off and on,

the user is encouraged to try to correct the interference by one or more of the

following measures:

• Reorient or relocate the receiving antenna.

Introduction

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 dis-

charge can damage computer components without causing any signs of physical

damage. You must take extra care in handling them to ensure against electro-

static 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 compo-

nents, contacts or connections.

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

modules or connectors by their ends.

Important:

Electrostatic discharge (ESD) can damage your processor

, disk drive and

other components. Perform the upgrade instruction procedures described

at an ESD workstation 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 chassis. If a wrist strap is

unavailable, establish and maintain contact with the system chassis

throughout any procedures requiring ESD protection.

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 instal-

lation or servicing. After installation or servicing, cover the system chassis

before plugging the power cord.

Battery:

• Danger of explosion if battery incorrectly replaced.

• Replace only with the same or equivalent type recommend by the manufac-

turer.

• Dispose of used batteries according to local ordinance.

Hardware Installation

JP5 (for USB 0-1), JP4 (for USB 4-7) and JP8 (for USB 2-3) are used to select

the power of the USB ports. Selecting 5V_standby will allow you to use a USB

keyboard to wake up the system.

Important:

If y

ou are using the Wake-On-USB Keyboard/Mouse function for 2 USB

ports, the 5V_standby power source of your power supply must support

≥1.5A. For 3 or more USB ports, the 5V_standby power source of your

power supply must support ≥2A.
