Power Connectors
Two main power connectors, located at #1 and #2, are connected to busbars from the power
distribution board in the system. Four 4-pin power connectors (JRSC_PWR1~ JRSC_PWR4)
are used for riser cards. Another two 4-pin power connectors (JAIOM_PWR1 and JAIOM_
PWR2) provide additional power for Advanced I/O modules. All these power connectors meet
the ATX SSI EPS 12V specification and must be connected to your power supply to provide
adequate power to your system.
