Connecting Cables
Now that the motherboard is installed, the next step is to connect the cables to
the board. These include the data cables for the peripherals and control panel and
the power cables.
Connecting Data Cables
The cables used to transfer data from the peripheral devices have been carefully
routed to prevent them from blocking the flow 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.
The following data cables (with their locations noted) must remian connected. (See
the layout on page 5-12 for connector locations.)
•
SATA drive cables (I-SATA0 ~ I-SATA3)
•
Control Panel cable (JF1)
Connecting Power Cables
The A1SAM-2550F has a 24-pin primary power supply connector (JPW1) for con-
nection to the ATX power supply. See Section 5-9 for power connector pin defini-
tions.
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.
