Safety Precautions
SBC-775
Pentium®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
System On On
System Suspend Flashes eight times/sec.
System Off Flashes once/sec.
