 II Full-size CPU Card with SSD

Part no. 2007775001   2nd Ed.   Printed in Taiwan   Nov. 1998

Quick Installation Guide

Warning! Always completely disconnect the power cord

from your chassis whenever you work with the

hardware. Do not make connections while the

power is on. Sensitive electronic components

can be damaged by sudden power surges. Only

experienced

electronics personnel should open the PC chas-

sis.

Caution! Always ground yourself to remove any static

charge before touching the CPU card. Modern

electronic devices are very sensitive to static

electric charges. As a safety precaution, use a

grounding wrist strap at all times. Place all

electronic components in a static-dissipative

surface or static-shielded bag when they are not

in the chassis.

ATX Power Control Connectors

(J7 and J1)

ATX feature connector (J7) and soft power

switch connector (J1)

The SBC-775 can support an advanced soft power switch function
if an ATX power supply is used. To enable the soft power switch
function:

1. Take the specially designed ATX-to-PS/2 power cable out of

the SBC-775's accessory bag.

2. Connect the 3-pin plug of the cable to J7 (ATX feature

connector).

3. Connect the power on/off button to J1. (A momentary type of

button should be used.)

Warnings: 1. Make sure that you unplug your power supply

when adding or removing expansion cards or

other system components. Failure to do so may

cause severe damage to both your CPU card and

expansion cards.

2. ATX power supplies may power on if certain

motherboard components or connections are

touched by metallic objects.

Important: Be sure that the ATX power supply can take at

least a 10 mA load on the 5 V standby lead

(5VSB). If not, you may have difficulty powering

on your system.

Controlling the soft power switch

It is easy to control the ATX soft power switch. Pushing the
button once will switch the system between the "On" and "Sus-
pend" power modes. Pushing the button for more than 4 seconds
while in the "On" mode will turn the system off. Users can also
identify the current power mode through the system's power LED,
as indicated below:

ATX Power Mode LED Status
