ATX Main PWR (JPW1) and CPU
PWR Connectors (JPW2)
The 24 - pin main power connector
(JPW1) is used to provide power to
the motherboard. The 8-pin CPU PWR
connector (JPW2) is also required for
the processor. These power connectors
meet the SSI EPS 12V specification. See
the table on the right for pin definitions.
Caution:To prevent damage to the power supply or motherboard, please use a
power supply that contains a 24-pin and two 8-pin power connectors. Be sure to con-
nect these to the 24-pin and the two 8-pin power connectors on your motherboard to
supply adequate power to your system. Failure to do so will void the manufacturer
warranty on the power supply and motherboard.
Processor Power Connectors
JPWR1 and JPWR2 must also be
connected to the power supply to pro-
vide power for the processors. See the
table on the right for pin definitions.
Ethernet Ports
Two Ethernet ports (LAN1/LAN2) are
located next to the VGA port on the
I/O Backpanel. These ports provide
connectivity with speeds up to 1Gb/s.
Please see the table on the left for the
pin definitions.
