Chapter 2: Board Installation

Precaution:The QUAD CPU Card ssupports EPS12V power supplies (24-pin+8-pin+8-

pin) and will not operate with any other types.

DO NOT USE ATX 2.x, ATX12V or ATXGES power supplies as they will damage the

board and void your warranty.

How to install our products right… the first time

The first thing you should do is read this user’s manual. It contains important information

that will make configuration and setup much easier. Here are some precautions you

should take when installing your motherboard:

(1) Ground yourself properly before removing your motherboard from the antistatic

bag. Unplug the power from your computer power supply and then touch a

safely grounded object to release static charge (i.e. power supply case). For the

safest conditions, TYAN recommends wearing a static safety wrist strap.

(2) Hold the motherboard by its edges and do not touch the bottom of the board, or

flex the board in any way.

(3) Avoid touching the motherboard components, IC chips, connectors, memory

modules, and leads.

(4) Place the motherboard on a grounded antistatic surface or on the antistatic bag

that the board was shipped in.

(5) Inspect the board for damage.

(6) Specially take care of the 2 HT slots on the solder side (bottom) of the

motherboard.

The following pages include details on how to install your motherboard into your chassis,

as well as installing the processor, memory andcables.

NOTE DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED
