Connecting Power Cables
The NovaScale R422 X7DBT/X7DBT-INF motherboard has two 20-pin ATX power supply
connectors for connection to the ATX power supply. Only one of these from each board
should be connected to the power supply . The "Primary ATX Power Header" is used to
supply power to the primary serverboard and the "Secondary ATX Power Header" is used
to supply power to the secondary serverboard. Connect the power supply to only one of
these on both boards (primary = left, secondary = right when viewed from front of server).
See Section 5-9 for power connector pin de fi nitions.
Connecting the Control Panel
JF1 contains header pins for various front control panel connectors. See Figure 5-1 for the
pin locations of the various front control panel buttons and LED indicators. All JF1 wires
have been bundled into a single ribbon cable to simplify this connection. Make sure the red
wire plugs into pin 1 as marked on the board. The other end connects to the Control Panel
PCB board, located just behind the system status LEDs on the chassis.
