5-3 Connecting Cables
Now that the serverboards are installed, the next step is to connect the cables to
the boards. 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 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.
SATA drive cables (I-SATA0 ~ I-SATA1)
Control Panel cable (JF1)
Connecting Power Cables
The NovaScale R422-E1/R422-INF-E1 serverboard has two 20-pin ATX power sup-
ply connectors 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.
