2.9 Installing DIMMs
The procedure for installing DIMMs is described below. Please follow
these steps carefully. The number of pins are different on either side of
the breaks, so the module can only fit in one way. DIMM modules have
different pin contacts on each side, and therefore have a higher pin den-
sity.
1.
Make sure that the two handles of the DIMM socket are in the
"open" position. i.e. The handles remain leaning outward.
2.
Slowly slide the DIMM module along the plastic guides on both
ends of the socket.
3.
Press the DIMM module right down into the socket, until you hear
a click. This is when the two handles have automatically locked the
memory module into the correct position of the socket.
To remove the memory module, just push both handles outward, and the
module will be ejected from the socket.

The PCA-6773 can support an advanced soft power switch function, if an
ATX power supply is used. To enable the soft power switch function:
1.
Get the specially designed ATX-to-EBX power cable
2.
Connect the 3-pin plug of the cable to CN24 (ATX feature connec-
tor).
3.
Connect the power on/off button to CN1. (A momentary type of
button should be used.)
Important
Make 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 power-
ing on your system.
