Connecting Data Cables
The cables used to transfer data from the peripheral devices have been carefully
routed to prevent them from blocking the fl ow of cooling air that moves through
the system from front to back. If you need to disconnect any of these cables, you
should take care to keep them routed as they were originally after reconnecting
them (make sure the red wires connect to the pin 1 locations). The following data
cables (with their locations noted) should be connected. (See the serverboard layout
for connector locations.) Note that each connection listed should be made for both
serverboards in the chassis.
• Control Panel cable (JF1)
Connecting Power Cables
The X8DTT-H(F)/HIBX(F)/HIBQ(F) serverboard has two 20-pin ATX power supply
connectors (JWR1) 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
defi 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.
