Connecting Cables
Now that the serverboard is installed, the next step is to connect the cables to the
board. These include the data (ribbon) cables for the peripherals and control panel
and the power cables.
Connecting Data Cables
The ribbon cables used to transfer data from the peripheral devices have been care-
fully 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 page for connector locations.)
SAS drive cables (JSM1, JSM2)
Control Panel cable (JF1)
Floppy cable (J12)
CD-ROM drive cable (J6)
Connecting Power Cables
The X6DH3-G2 has a 24-pin primary power supply connector (JPW1) for connection
to the ATX power supply. In addition, there is an 8-pin processor power connector
(J1D1) and a 4-pin auxiliary power connector (J38) that both must be connected to
your power supply. 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 connec-
tion. 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. See Chapter 5 for details and pin descriptions.
