Chapter 5: Advanced Serverboard Setup

5-3 Connecting Cables
Now that the processors are installed, the next step is to connect the cables to the
serverboard. 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 in preconfi gured systems 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 reroute them as they were originally after
reconnecting them and be aware of the pin 1 locations. If you are confi guring the
system, keep the airfl ow in mind when routing the cables.
Connecting Power Cables
The serverboard has a 24-pin primary power supply connector designated J24
for connection to the power supply. There are also two 8-pin power connectors,
JPWR1 and JPWR2. Connect the appropriate cable connectors from the power
supply. Connector pin defi nitions are explained later in the chapter.
Connecting the Control Panel
JF1 contains header pins for the front control panel connectors. All JF1 wires have
been bundled into single keyed ribbon cable to simplify their connection. The red
wire in the ribbon cable plugs into pin 1 of JF1. Connect the other end of the cable
to the Control Panel printed circuit board, located just behind the system status
LEDs in the chassis.
See the Connector Defi nitions section in this chapter for details and pin descriptions
of JF1.
