5.2 Connecting Cables
The cables listed below should already be connected to the serverboard. These include
the data cables for the peripherals and control panel and the power cables.
5.2.1 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 for connector locations.)

SAS (SAS0 ~ SAS7) or SATA (I-SATA0 ~ 5) and SAS (S-SATA0~3) drive cables
 Control Panel cable (JF1)
mportant Make sure the cables do not come into contact with the fans
5.2.2 Connecting Power Cables
The R423-E3 serverboard has a 24-pin primary power supply connector (J22) for
connection to the ATX power supply. In addition, there are two 8-pin 12V processor power
connectors (JPW1 and JPW2) that must be connected to your power supply. See Section 5-
9 for power connector pin definitions.
5.2.3 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
Chapter 5 for details and pin descriptions
