This chapter shows you how to connect two monitors to your DCD.
The following topics are covered:
“Connecting the Monitor Cables to the DCD (Single Head Octane System)”
“Connecting the Monitor Cables to the DCD (Dual Head Octane System)”
“Connecting the Monitor Cables to the DCD (Silicon Graphics Fuel Workstation)”
“Connecting the Monitor Power Cables and Powering On Your Workstation”
-
Caution: Make sure both of the monitors that are connected to the DCD have the same or similar display capabilities.
Connect the monitor cables as follows:
Power off your workstation.
Place the monitors side by side.
Connect the VGA end of each DVI/VGA cable to the VGA connector on the back of each monitor, and then tighten the thumbscrews on both sides of each connector (see Figure 3-1).
Face the front of the monitors and place one monitor on the left and the other monitor on the right.
Follow the instructions in this section to connect the monitors to the DCD on a Single Head Octane system. For a Dual Head Octane system, proceed to “Connecting the Monitor Cables to the DCD (Dual Head Octane System)”. For a Silicon Graphics Fuel workstation, proceed to “Connecting the Monitor Cables to the DCD (Silicon Graphics Fuel Workstation)”.
Connect the left monitor's DVI/VGA cable to the top video connector (channel 0) on the DCD, as shown in Figure 3-2.
Channel 0 drives the left monitor with the image from the top of the frame buffer.
Connect the right monitor's DVI/VGA cable to the bottom connector (channel 1) on the DCD, as shown in Figure 3-2.
Channel 1 drives the right monitor with the image from the bottom of the frame buffer.
Tighten the thumbscrews on both sides of each video connector.
Caution: To ensure proper cursor movement, make sure you connect the monitor cables to the correct video connectors on the rear of your workstation.
Follow the instructions in this section to connect the monitors to the DCD on a Dual Head Octane system. For a Single Head Octane system, refer to “Connecting the Monitor Cables to the DCD (Single Head Octane System)”. For a Silicon Graphics Fuel workstation, proceed to “Connecting the Monitor Cables to the DCD (Silicon Graphics Fuel Workstation)”.
If you are connecting the monitors to a DCD on the primary (upper) head, proceed to the following section “Connecting to a DCD on the Primary (Upper) Graphics Head”.
If you are connecting the monitors to a DCD on the secondary (lower) head, proceed to “Connecting to a DCD on the Secondary (Lower) Graphics Head”.
To connect the monitors to a DCD on the primary (upper) graphics head in a Dual Head system, follow these steps:
Connect the left monitor's DVI/VGA cable to the top video connector (channel 0) on the DCD, as shown in Figure 3-3.
Channel 0 drives the left monitor with the image from the top of the frame buffer.
Connect the right monitor's DVI/VGA cable to the bottom connector (channel 1) on the DCD, as shown in Figure 3-3.
Channel 1 drives the right monitor with the image from the bottom of the frame buffer.
Tighten the thumbscrews on both sides of each video connector.
Caution: To ensure proper cursor movement, make sure you connect the monitor signal cables to the correct video connectors on the rear of your workstation.
To connect the monitors to a DCD on the secondary (lower) graphics head in a Dual Head system, follow these steps:
Connect the left monitor's DVI/VGA cable to the bottom video connector (channel 0) on the DCD, as shown in Figure 3-4.
Channel 0 drives the left monitor with the image from the top of the frame buffer.
Connect the right monitor's DVI/VGA cable to the top connector (channel 1) on the DCD, as shown in Figure 3-4.
Channel 1 drives the right monitor with the image from the bottom of the frame buffer.
Tighten the thumbscrews on both sides of each video connector.
Caution: To ensure proper cursor movement, make sure you connect the monitor signal cables to the correct video connectors on the rear of your workstation.
Follow the instructions in this section to connect the monitors to the DCD on a Silicon Graphics Fuel workstation. For a Single Head Octane system, see “Connecting the Monitor Cables to the DCD (Single Head Octane System)”. For a Dual Head Octane system, refer to “Connecting the Monitor Cables to the DCD (Dual Head Octane System)”.
Connect the left monitor's DVI/VGA cable to the left video connector (channel 0) on the DCD, as shown in Figure 3-5.
Channel 0 drives the left monitor with the image from the top of the frame buffer.
Connect the right monitor's DVI/VGA cable to the right connector (channel 1) on the DCD, as shown in Figure 3-5.
Channel 1 drives the right monitor with the image from the bottom of the frame buffer.
Tighten the thumbscrews on both sides of each video connector.
Caution: To ensure proper cursor movement, make sure you connect the monitor cables to the correct video connectors on the rear of your workstation.
Connect the power cable for each monitor as follows (see Figure 3-6):
Connect the female end of the power cable to the power connector on the back of the monitor.
Plug the male end into a three-prong grounded electrical outlet.
Plug your workstation's power cord into an electrical outlet.
Press the power button on the front of your workstation.
Press the power switch on the left monitor, then press the power switch on the right monitor to power on the monitors.
For information on configuring the DCD, proceed to Chapter 4, “Configuring the DCD”.
To verify a successful installation of the DCD, follow these steps:
Open a UNIX shell.
At the prompt, enter hinv
A hardware inventory list will appear, similar to the one shown in Figure 3-7.
Look for the following line describing the DCD:
DCD
If the above line does not appear, proceed to Chapter 5, “Troubleshooting and Technical Specifications”.
Note: If a DCD is installed in a Silicon Graphics Fuel workstation, or if one or two DCDs are installed in a Dual Head Octane system, the hardware inventory list will be slightly different than the Single Head Octane inventory shown in Figure 3-7. However, you should still look for a line that says “DCD” (or look for two such lines, if you have two DCDs installed).
