5-2 Connecting Cables
Connecting Data Cables
The cables used to transfer data from the peripheral devices have been carefully
routed in preconfigured systems 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 reroute them as they were originally
after reconnecting them (make sure the red wires connect to the pin 1 locations). If
you are configuring the system, keep the airflow in mind when routing the cables.
Connecting Power Cables
The has two primary power supply connectors designated J3 and J12.
Three 8-pin power connectors (JPWR1-3) are used to provide power to backplane
devices and another four 8-pin power connectors (JPWR4-7) are used for GPU
devices. See the Connector Definitions section in this chapter for power connector
pin definitions.
Connecting the Control Panel
JF1 contains header pins for various front control panel connectors. See Figure 5-2
for the pin locations of the front control panel buttons and LED indicators. Please
note that even and odd numbered pins are on opposite sides of each header.
All JF1 wires have been bundled into single cable to simplify their connection. One
end of the cable plugs into JF1 and the other end to the Control Panel printed circuit
board, located just behind the system status LEDs in the chassis.
See the Connector Definitions section in this chapter for details and pin descriptions
of JF1.
