Chapter 5: Advanced Serverboard Setup

5-4 Connecting Cables

Now that the processors are installed, the next step is to connect the cables to the serverboard. These include the data (ribbon) cables for the peripherals and control panel and the power cables.

Connecting Data Cables

The ribbon 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 (make sure the red wires connect to the pin 1 locations). If you are confi guring the system, keep the airfl ow in mind when routing the cables. The following data cables (with their serverboard connector locations noted) should be connected. See the serverboard layout diagram in this chapter for connector locations.

CD-ROM cable (JIDE#1)

Floppy drive cable (JFDD1)

SAS drive cables (JSM2)

Control panel cable (JF1, see next page)

Connecting Power Cables

The H8DCR-3 has a 20-pin primary power supply connector at "J1B4" designated "ATX Power" for connection to the ATX power supply. Connect the appropriate connector from the power supply to the "ATX Power" connector to supply power to the serverboard. See the Connector Defi nitions section in this chapter for power connector pin defi nitions.

In addition, your power supply must be connected to the 8-pin processor connec- tor at JPW2. For systems with high load confi gurations, a third (auxiliary) power connector at J32 should also be connected to your power supply.
