This chapter shows you how to install the DCD in your Octane or Octane2 workstation with Single Head VPro graphics. The following topics are covered:
Make sure your shipment contains the items shown in Figure 1-1.
To use the DCD, your workstation must have a VPro V12 graphics board installed. If you have a Dual Head workstation, see Chapter 2, “Installing the DCD in a Dual Head Octane2”.
To verify that your system contains a VPro V12 graphics board, follow these steps:
Open a UNIX shell.

You will see output similar to the following:
2 250 MHZ IP30 Processors CPU: MIPS R10000 Processor Chip Revision: 3.4 FPU: MIPS R10010 Floating Point Chip Revision: 0.0 Main memory size: 512 Mbytes Xbow ASIC: Revision 1.4 Instruction cache size: 32 Kbytes Data cache size: 32 Kbytes Secondary unified instruction/data cache size: 1 Mbyte Integral SCSI controller 0: Version QL1040B (rev. 2), single ended Disk drive: unit 1 on SCSI controller 0 Integral SCSI controller 1: Version QL1040B (rev. 2), single ended IOC3 serial port: tty1 IOC3 serial port: tty2 IOC3 parallel port: plp-1 Graphics board: V12 Integral Fast Ethernet: ef0, version 1, pci 2 Iris Audio Processor: version RAD revision 12.0, number 1
Look for the following line describing your graphics board:
Graphics board: V12
If your graphics board is not listed as V12, you cannot use the DCD. For more information, contact your authorized SGI sales representative.
If your Octane or Octane2 workstation has IRIX 6.5.14, you must also have a software patch installed before you can install the DCD.
To determine the version of the IRIX operating system installed on your Octane or Octane2 system, follow the instructions in this section.
From an IRIX command prompt, type:
1% uname -R |
You will see output similar to the following:
6.5 6.5.13f |
If your system is running IRIX version 6.5.14, you need patch 4426 before you install the DCD. To determine if you have patch 4426 installed, type the following at an IRIX command prompt:
2% versions patchSG0004426 |
If the output of this command shows nothing under the headings “Name,” “Date,” and “Description,” you do not have patch 4426 installed. You must install this patch (or you must upgrade your system to IRIX 6.5.15 or later, when released) before installing the DCD.
If the output of this command includes items below the Name-Date-Description headings, you do have patch 4426 installed.
To install the DCD, you must remove your workstation's XIO Tri-Module. Before you begin this operation, follow these steps:
Open the cover and press the power button to power off your workstation (see A in Figure 1-2).
Unplug the power cord (B).
Press the monitor power switch to power off your monitor (C).
Wait 5 minutes before removing the XIO Tri-Module.
Warning: The heat sinks on the XIO boards get very hot. Wait 5 minutes after powering off your workstation before you remove the XIO Tri-Module. Test the temperature of the heatsinks before handling any of the XIO boards.
Remove all the cables from the XIO Tri-Module (only the monitor cable on the VPro graphics board is shown in Figure 1-3).
Note: The following illustrations show a workstation with a PCI module installed. Your workstation may not have a PCI module, but the DCD installation is the same.
 | Caution: The internal components are extremely sensitive to static electricity; always wear the wrist strap when you handle parts inside your workstation. |
To attach the wrist strap, follow these steps:
Unroll the first two folds of the band (see A in Figure 1-4).
Wrap the exposed adhesive side firmly around your wrist, unroll the rest of the band, then peel the liner from the copper foil at the opposite end (B).
Attach the copper foil to any exposed electrical ground, such as a metal part of the workstation (C).
You must remove your workstation's XIO Tri-Module so you can connect the DCD to the daughterboard slot on the VPro graphics board. Before removing the XIO Tri-Module, you must power off your workstation, wait 5 minutes to allow the heat sinks to cool, and attach the wrist strap, as described in the previous sections.
To remove the XIO Tri-Module, follow these steps:
Loosen the two captive screws in the XIO Tri-Module handles with the supplied Phillips screwdriver until the screws are disconnected from the chassis (see Figure 1-5).
Warning: The heat sinks on the XIO boards get very hot. Wait 5 minutes after powering off your workstation before you remove the XIO Tri-Module. Test the temperature of the heatsinks before handling any of the XIO boards. Grasp the sliding handles and pull until the sliding portion of the XIO Tri-Module protrudes about an inch from the chassis, as shown in Figure 1-6.
The sliding handles and XIO Tri-Module move out about one inch before the I/O panels move.
Grasp the XIO Tri-Module by the immovable handle, and support the base of the module as you remove it from the chassis, as shown in Figure 1-7.
Caution: Do not push on the sliding handles after you remove the XIO Tri-Module. Later when you reinsert the Tri-Module, the sliding handles must protrude.
| Caution: The compression connector on the XIO Tri-Module is very delicate and easily damaged. Do not touch or bump the gold bristled pad (see Figure 1-8). The connector is on the side opposite the handle, as shown in Figure 1-9. Do not grab the back of the XIO Tri-Module when you remove it, or the compression connector may be damaged. |
Always place a cap on the compression connector after removing the XIO Tri-Module (caps are included with your workstation). Before reinstalling the XIO Tri-Module in your workstation, remove the cap from the compression connector.
Before you remove the XIO Tri-Module, read “Care and Cleaning of the Compression Connector” in the Appendix section of your owner's guide.
The DCD connects to the daughterboard slot on the XIO Tri-Module VPro graphics board.
Place the XIO Tri-Module on a flat, antistatic surface with the VPro graphics board I/O panel on the left side, as shown in Figure 1-9. An empty antistatic bag on your desk works well.
When the XIO Tri-Module is out of the chassis, the sliding handles must protrude.
A label identifies each XIO slot (B on one side, C on the other). Slot B is the daughterboard slot where you connect the DCD, as described later in this chapter.
Place a cap on the XIO Tri-Module compression connector, as shown in Figure 1-9 and Figure 1-10.
Caps are included with your workstation.
Caution: To prevent damage to the connector, do not touch or bump the gold (front) surface. Remove the three screws from the VPro graphics board blank panel, as shown in Figure 1-11. Save the screws for later in the installation.
Remove the blank panel from the VPro graphics board, as shown in Figure 1-12.
Store the blank panel in a safe place. If you remove the DCD, you need to reinstall the VPro graphics board blank panel.
Remove the nylon standoff from the bag of parts and install it as follows:
Remove the screw that is located behind the daughterboard connector on the VPro graphics board (see A in Figure 1-13), and save it for later in the installation.
Insert the nylon standoff into the hole from which you removed the screw (B).
Seat the nylon standoff by turning it clockwise (C), but do not overtighten.
Remove the DCD from its antistatic bag.
Align the DCD I/O panel with the VPro graphics board I/O panel as follows:
Line up the DCD's two outside holes with the two outside holes on the VPro graphics board (see A in Figure 1-14).
Place the DCD on top of the VPro graphics board.
Line up the two locator slots on the outside of the DCD with the locator tabs on the outside of the VPro graphics board (B).
Seat the DCD connector in the VPro graphics board daughterboard slot, as follows:
Push the top edge of the DCD I/O panel against the VPro graphics board I/O panel (see A in Figure 1-15).
Note: As you push the board forward, the connectors move into alignment and partially seat without the assistance of downward pressure. Press down on the top of the DCD I/O panel to fully seat its locator slots over the VPro graphics board locator tabs (B).
Press down gently on the area above the DCD connector to make sure it is fully seated (C). See Figure 1-16 for a side view seating of the board.
Figure 1-16 shows a side view seating of the board.
Note: After you complete step 8, make sure the locator tabs at each end of the VPro graphics board I/O panel protrude through the locator slots on each end of the DCD I/O panel, as shown in Figure 1-17. Secure the DCD to the VPro graphics board with the three screws you removed from the blank panel, as shown in Figure 1-18.
Install the two outside screws first, then install the middle screw.
Note: Turn the screws until they are snug, but do not overtighten them. Place the screw you removed from the VPro graphics board into the hole behind the DCD connector (above the standoff), then tighten the screw by turning it clockwise, as shown in Figure 1-19.
The DCD is now securely connected to the VPro graphics board.
Remove the 13W3 cover and the two screws from the bag of parts.
Place the 13W3 cover over the VPro graphics board monitor port, with the padded side of the cover facing the monitor port, as shown in Figure 1-20.
When a monitor is not connected to the VPro graphics board monitor port, you must install the 13W3 cover to ensure that the system complies with local and international EMC regulations.
Align the two outside holes of the 13W3 cover with the two thumbscrew holes on the sides of the VPro graphics board monitor port.
Insert a screw in each hole of the 13W3 cover, then tighten each screw to secure the cover to the VPro graphics board, as shown in Figure 1-21.
| Caution: To prevent damage to your workstation, reinstall the XIO Tri-Module with the Graphics Board I/O panel aligned with the top of the workstation. |
Follow these steps to reinstall the XIO Tri-Module:
Remove the cap from the XIO Tri-Module compression connector.
Slide the XIO Tri-Module into the guides on the top and bottom of the workstation.
Before you insert the XIO Tri-Module, make sure the sliding handles protrude in a locked position from the I/O panels, as shown in Figure 1-22.
If the sliding handles are flush with the I/O panels, the XIO Tri-Module will stop during insertion. Pull out the sliding handles until the sliding portion of the XIO Tri-Module looks like Figure 1-22.
Grasp the immovable handle area with one hand while supporting the XIO Tri-Module with the other, and slide the module into the chassis.
Use the immovable handle to push the XIO Tri-Module into a locked position. The I/O panels are nearly flush with the workstation when properly inserted, but there is a slight variation in the depth of the boards.
Push the sliding handles until the sliding portion of the module is flush with the workstation.
Tighten the captive screws in the sliding handles, as shown in Figure 1-23.
Reconnect all cables to the XIO Tri-Module, except for the monitor cable.
You are finished installing your DCD.
Now go to Chapter 2 for instructions on connecting two monitors to the DCD.
If you want to remove the DCD and connect a monitor to the VPro graphics board monitor port, follow these steps:
Power off and prepare your workstation, as described earlier in this chapter.
Remove the XIO Tri-Module, as described earlier in this chapter.
Remove the DCD as follows (see Figure 1-24):
Reinstall the VPro graphics board blank panel, as shown in Figure 1-25.
Remove the two screws securing the 13W3 cover to the VPro graphics board, then remove the cover, as shown in Figure 1-26.
Reinstall the XIO Tri-Module, as described earlier in this chapter.
Connect a monitor to the VPro graphics board monitor port, as shown in Figure 1-27.
Connect one end of the monitor power cable to your workstation and the other end to a 3-prong grounded electrical outlet.
Power on your workstation and monitor.
