Chapter 2: Installation
2-4 Connecting Cables
After you have securely mounted the motherboard to the chassis,
you are ready to connect the cables. For P5MMA98 and P5MMA2, do
not connect the power cord to the input power (wall power plug)
until the system is completely installed. This procedure will prevent
power from being applied to the motherboard during installation.
When changing components, unplug the power cord for safety.
Power Supply Connectors
Attach power supply cables to PW1 for a 5V power supply or J16 for
ATX power. Do not force the cables, but make sure they are fully
seated. The two black wires on each power cable for PW1 sit next
to each other when correctly installed. See Table 2-8 for pin defini-
tions of a 5V power supply. See Table 2-9 for pin definitions of an
ATX power supply.
