5-3 Connecting the Motherboard
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 (make sure the red wires connect to the pin 1 locations). The following data
cables (with their locations noted) should be connected. (See the layout figure 5-4
on page 5-13 for connector locations.)
SATA drive data cables (I-SATA0 ~ I-SATA5)
•
Control Panel cable (JF1)
•
DVD-ROM drive cable (IDE#1)
•
USB cable (USB2/3)
•
COM Port cable (COM2)
•
Important! Make sure the cables do not come into contact with the fans.
Connecting Power Cables
The NovaScale R423-E2 motherboard has a 24-pin primary power supply connec-
tor (JPW1) for connection to the ATX power supply. In addition, there is a 4-pin
secondary power connector (JPW2) as well as an 8-pin processor power connector
(JPW3) that must be connected to your power supply. See Section 5-9 for power
connector pin definitions.
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 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. See figure 5-1 on page 5-4 for details and pin descriptions.
