The main power supply connector
(J22) meets the SSI EPS 12V speci-
fi cation. Refer to the table on the right
for the pin defi nitions of the ATX 24-pin

nect the 8-pin power connectors to
your power supply (see below).
Warning: To prevent damage to the power supply or serverboard, please
use a power supply that contains a 24-pin and two 8-pin power connec-
tors. Be sure to connect these to the 24-pin and the two 8-pin power con-
!
nectors on your serverboard to supply adequate power to your system.
Failure to do so will void the manufacturer warranty on the power supply
and serverboard.

connected to the power supply to pro-
vide power for the processors. See the
table on the right for pin defi nitions.
