Connector Definitions

Power Connectors
A 24-pin main power supply connector
(J24), and two 8-pin CPU power connectors
(JPWR1/JPWR2) are located on the
serverboard. These power connectors
meet the SSI EPS 12V specification
and must be connected to your power
supply to provide adequate power to the
system. See the tables on the right for
pin definitions.
Caution: To provide adequate power to
the serverboard, be sure to connect the
24-pin ATX PWR (J24) and the two 8-pin
power connectors (JPWR1, JPWR2) to the
power supply. Failure to do so may void the
manufacturer warranty on your power supply
and serverboard.
