nector (J1B4) meets the SSI (Super-

connector (above), the 12v, 8-pin
processor power connector at JPW2
must also be connected to your power
supply. This connection supplies
power to the CPUs. See the table on
the right for pin defi nitions.
Auxiliary Power Connector
The 4-pin auxiliary power connector at
J32 must also be connected to your
power supply. This connection sup-
plies extra power that may be needed
