Chapter 3. Getting Started
|Warning: This chapter describes how to configure and operate your system correctly.
The Onyx rackmount graphics workstation operates on 220-400 VAC. Use extreme caution when working around this voltage. Never install or remove power cords without first turning off the equipment.
There is 48 VDC present on the system midplane. This voltage is present even if the system has been reset or halted.
|Caution: The Onyx system can weigh over 1000 pounds when fully configured. Use at least two people when moving the system chassis, and take care to ensure that the system does not tip or become unbalanced. Two people should also be used to move the monitors. Be sure to practice proper lifting techniques.
Customer maintenance is limited to the outside of the chassis, which comprises the peripherals and cables attached to the I/O panel. No user-serviceable parts are found within the chassis.
|Note: This product requires the use of external shielded cables in order to maintain compliance with Part 15 of the FCC rules.
A high-resolution, 1600 x 1200-pixel 21-inch monitor ships as the standard monitor for the Onyx rackmount systems. This section describes how to install the 21-inch monitor. Connect the monitor you received by following the steps in the applicable section.
|Caution: Before plugging any monitor into either a 110 VAC or a 220–240 VAC outlet, be sure that the electrical rating on the label is in either the 110 or the 220–240 range, whichever applies.
When using a monitor in locations that do not have either of these outlets, contact your Silicon Graphics system support engineer before plugging in the monitor power cable.
|Note: If you use a monitor that has white switches below the RGB posts, make sure they are pressed in so that they are in the 75-ohm position; otherwise, the monitor displays the wrong colors.
Use only the cables specified to connect the monitor to the Onyx rackmount chassis.
Connecting a 21-Inch Monitor
The InfiniteReality, VTX, or RE2 graphics system uses a 21-inch, high-resolution monitor. This monitor uses a 13W3-to-13W3 cable. Connect one of the 13W3 fittings to the I/O panel and the other to the back of the monitor. See Figure 3-1 for an example of the connectors on the 21-inch monitor.
When the system is booted, the monitors will operate in their default resolution of 1280 x 1024. To change the default video format, you may use the setmon command. For more information about the setmon command options, see the setmon reference (man) page.

The Onyx InfiniteReality, RE2, or VTX graphics systems provide connections to a number of video peripherals.
InfiniteReality Graphics Peripherals
The standard InfiniteReality graphics board set allows for the connection of two high-resolution 21-inch monitors. The following peripherals can also be connected:
Before using the graphics software, connect the composite or S-Video monitor or VCR to the appropriate output ports on the I/O panel. Refer to Figure 3-4.
Both the CMPST ports use standard BNC video connectors. They are electrically identical: a tape deck or monitor can be connected to either port. Connect a cable to your composite monitor and to either of the CMPST ports. Connect another cable to your VCR and to the other composite port.
The S-Video port is an output port that connects to an S-Video monitor or SVHS video cassette recorder. The port uses a 4-pin mini DIN connector. The port can connect to either the S-Video monitor or to the VCR.
|Caution: You must use the appropriate video peripherals. The composite video ports are connected to video monitors and VCRs that operate in NTSC or PAL video format. The S-Video port connects to VCR equipment that uses the SuperVHS format.
Video peripherals are connected to the InfiniteReality graphics I/O panel, as shown in Figure 3-4. Connections for Reality Engine2 or VTX are shown in Figure 3-4 in the next subsection.
Note that frame grab functions in InfiniteReality are done with the Sirius VideoTM option board. See the Sirius Video Programming and Configuration Guide (P/N 007-2238-00x).
Figure 3-3. InfiniteReality Video Peripherals Connection Example
RE2 and VTX Graphics Peripherals
In addition to the standard high-resolution 21-inch monitor, the following peripherals can be connected to RE2 or VTX systems:
Before using the graphics software, connect the composite or S-Video monitor and VCR to the appropriate output ports on the I/O panel. Refer to Figure 3-4.
The CMPST A and CMPST B ports are standard BNC video connectors. They are electrically identical: a tape deck or monitor can be connected to either port. Connect a cable to your composite monitor and to either the CMPST A or CMPST B port. Connect another cable to your VCR and to the other composite port.
The video ports (S-Video A and S-Video B) are output ports that connect to an S-Video monitor and SVHS video cassette recorder. These ports use four-pin mini DIN connectors. They are also electrically identical: each port can connect to either the S-Video monitor or to the VCR. Connect a cable from your S-Video monitor to either S-Video A or S-Video B. Connect a cable from the tape deck to the remaining S-Video port.
|Caution: You must use the appropriate video peripherals. The composite video ports are connected to video monitors and VCRs that operate in NTSC or PAL video format. The S-Video ports connect to VCR equipment that uses SuperVHS format.
Figure 3-4. RE2 and VTX Video Peripherals Connection Example
Connecting Your Keyboard and Mouse
Your system comes with a standard 101-key international keyboard. The keyboard has two identical plug receptacles, located in the upper right and left corners. These receptacles accepts the 6-pin mini-DIN connectors from either the keyboard cable or the mouse.
To install a keyboard:
Choose the side of the keyboard where the mouse will be located and insert the mouse cable connector into the nearest keyboard receptacle.
Attach one end of the keyboard cable to the remaining keyboard receptacle. Attach the other end of the keyboard cable to the keyboard connector on the main I/O panel (see Figure 3-5).
|Caution: Do not unplug the keyboard cable from the I/O panel while the system power is on; system damage can result.
Figure 3-5. Keyboard Connection
SCSI Requirements and Configurations
All Onyx rackmount systems are configured with a minimum of two fully independent SCSI channels provided by the IO4 board. In its maximum configuration, with the addition of multiple SCSI mezzanine boards, the Onyx rackmount graphics workstation can have 48 SCSI channels. A portion of these channels can be configured as either single-ended or differential SCSI.
The difference between single-ended and differential SCSI channels is defined as follows: a single-ended SCSI channel pairs each signal line with a ground line. Differential SCSI channels pair each signal line with a second signal that is the balanced inverse of the first. This configuration makes differential SCSI less susceptible to signal degradation due to noise and more suitable for remote (longer) cabling.
The IO4 board can communicate with both internal and external SCSI devices over either single-ended or differential SCSI channels. Generally, external SCSI channels are differential, and internal channels are single-ended. The requirements and limitations of both single-ended and differential SCSI channels are described below.
The maximum allowable length for single-ended (standard) SCSI cabling is 19.6 feet (6 meters). This maximum length reflects the combined lengths of both the internal and external cables. A single-ended SCSI bus can support a maximum of eight SCSI devices (including the SCSI controller board).
The maximum allowable length for differential SCSI is 80 feet (25 meters). As with single-ended SCSI, this length is the sum of both the internal and external cables. The differential SCSI bus supports a maximum of 16 devices (including the controller board).
|Note: The most common reason for SCSI device failure is insufficient noise margins due to exceeding the maximum cable length, cable impedance mismatches, or a combination of both. If you are having trouble with certain devices, particularly external devices, be sure to verify that you have not exceeded the maximum SCSI cable length.
Always use the shortest cable possible. Route external cables away from potential damage due to foot traffic, cleaning, and so on.
If you have additional questions about SCSI connections and cable lengths, contact your Silicon Graphics representative.
|Note: To operate multiple external SCSI devices, you must order your system's IO4 with extra mezzanine SCSI channel daughter boards. These are the mezzanine options mentioned in Chapter 1; they connect to the I/O panel and then to external devices.
Terminating SCSI Channels
SCSI channels must be terminated at both the IO4 board (or S mezz board) and at the last device on the channel. The internal SCSI channels (in the SCSIBoxes) are configured so that front loading devices (FLDs) can be added or removed without affecting the channel termination; however, if devices are being added or removed from an external SCSI bus, you must verify that the correct external channel termination is maintained.
|Caution: Single-ended and differential SCSI buses must be terminated with single-ended and differential terminators, respectively. Terminating a bus with the wrong terminator can cause system damage.
|Caution: All installed IO4 boards and/or SCSI mezzanine boards are terminated at the time of installation. Do not attempt to open the cardcages to verify channel termination.
Installing and Removing FLDs
This section describes the physical installation and removal of a front- loading drive (FLD) from the Onyx workstation. It is assumed that the system has already been configured for the drives being removed or installed.
|Note: If the FLD is not configured, refer to Chapter 4, “Installing and Using Optional Peripherals,” for configuration instructions.
Install an FLD in the SCSIBox drive enclosure as follows:
Ensure that the system power is turned off. If the system is running, refer to the “Powering Off the System” section, later in this chapter.
Open the lower front access door of the system chassis.
Release the two captive wing nuts securing the SCSIBox door and allow the door to swing down (see Figure 3-6).
Orient the FLD relative to the SCSIBox so that the drive is facing toward the right (see Figure 3-7).
Select a vacant drive bay and carefully align the rails on the drive sled with the corresponding rails in the drive bay.
Slide the FLD into the bay until the locking mechanism is engaged and the locking lever on the drive sled moves down to the locked position. Push the lever down to ensure it is fully engaged.
|Note: If the FLD is being installed for the first time, ensure that the drive is not terminated.
Verify that the device ID was not accidently changed during the installation.
Close the SCSIBox door.
Power on the system as described in the section entitled “Powering On the System.”
See the IRIX Admin: Disks and Filesystems manual, or the IRIX Admin: System Configuration and Operation manual, for information needed to configure software.
Remove an FLD from the SCSIBox as follows:
Repeat steps 1 through 3 from the installation procedure.
Move the locking lever, on the drive sled, up as far as it will go.
Carefully withdraw the FLD from the SCSIBox.

Figure 3-7. Installing a Front-Loading Device
Connecting Your System to an Ethernet
The Onyx graphics workstation comes with a 15-pin AUI Ethernet connector. You can order optional boards for additional Ethernet connections.
Power on the Onyx rackmount graphics workstation as follows:
Verify that the system power switch, located in the lower front corner of the system chassis, is turned off.
Insert the female end of the system power cable into the receptacle at the rear of the system chassis (see Figure 3-8). Secure the cable by turning the connector clockwise to engage the twist lock.
Connect the male end of the power cable to an AC power source using the appropriate receptacle, either a locking collar or a twist-lock connector (see Figure 3-8). Turn the locking collar on the keyed connector clockwise to engage the locating tabs on the AC outlet. Turn the twist-lock connector clockwise to secure it to the AC outlet.
|Warning: See the Challenge/Onyx Site Preparation Guide for the system's power requirements.The Onyx rackmount workstation operates on 220-400 VAC. Use extreme caution when working around this voltage. Never install or remove power cords without first turning off the equipment.
If the monitors and peripherals are equipped with voltage select switches, verify that they are set for the appropriate AC voltage.
Connect the power cords from the monitor(s) and additional peripherals to the appropriate three-pronged grounded outlets.
Turn on the system power switch (see Figure 3-9).
Turn on the monitors, followed by any attached peripherals.
|Note: All internal storage devices are automatically powered up by the System Controller.
Boot the system as described in “Booting the System.”
Figure 3-8. Connecting the System Power Cable
Boot your system by performing the following steps:
Power on the system, as described in the preceding section, “Powering On the System.”
Open the lower front door to the system chassis.
Insert the system key into the key switch, located to the right of the System Controller's display. Turn the key switch to the On position (see Figure 3-10).
|Note: The System Controller begins the power-on sequence. The green power-on LED, located above the function buttons, lights to indicate that power has been applied to the system midplane. The amber fault LED then lights to indicate that power has been supplied to the System Controller. The fault LED goes out when the System Controller has successfully initialized and the power-on tests have completed.
Figure 3-10. System Controller Key Switch
After the bootmaster CPU has been selected, the system's progress can be monitored on the System Controller's display. Use the function buttons to select the Boot Status menu, and a series of status messages are displayed during a normal boot cycle (see Table 3-3).
|Note: Do not press any of the front panel buttons until the “Boot Arbitration is Complete” message is displayed by the System Controller. Pressing the buttons before the bootmaster CPU is identified will abort the boot arbitration process.
When the power-on tests have completed, you see this message:

If additional software is desired, it must be downloaded either locally (using a CD-ROM drive) or downloaded remotely over the network. See the IRIX Admin: Disks and Filesystems manual for additional information about mounting and configuring drives. Refer to the IRIX Admin: Software Installation and Licensing manual for the detailed steps required to download the software.
|Note: A copy of the IRIX operating system is supplied with the system on a compact disc. Place the CD in a secure place in case you ever need to reinstall the operating system.
InfiniteReality Combiner Programming Overview
InfiniteReality graphics provides a programming utility, the Video Format Combiner, with two interfaces:
This section is mainly concerned with the GUI version of (ircombine). For information on ircombine(1G), consult its reference (man) page.
Use the Combiner only with Onyx InfiniteReality or i-Station graphics systems. For RE2 and VTX graphics systems you must use the video out panel (described in the next section) or other custom applications.
Both the line-command and GUI utilities create video format combinations—descriptions of raster sizes and timing to be used on video outputs—as well as configure the underlying framebuffer. You can use a video format combination as the current video configuration, store it as the default configuration to be used at system power on or graphics initialization, or save it in a video format combination file. You can create a combination from scratch or by modifying a current or default combination or a saved combination.
The Combiner utility is useful for applications that need multiple channels, for such uses as visual simulation, virtual reality, or entertainment. The Combiner utility instructs the video subsystem to convert digital information stored in the graphics framebuffer into a variety of video signals (or channels), ranging from standard high-resolution (1280 x 1024) to low-resolution outputs. The output can then be displayed on additional monitors, projection devices, or stored on videotape, in any combination. Output can be genlocked to an external reference signal.
The InfiniteReality pipeline can process image, geometric, and video data concurrently at real-time rates. The pipeline can convert a full-screen high-resolution display to a composite (NTSC or PAL) video output port: your application can record in real time whatever is being displayed on the screen.
To launch and display the Combiner's GUI, enter the following in any available IRIX window:
To specify a different display from the current workstation, such as a different pipe of a rackmount system, a remote workstation, or a specific pipe of a remote rackmount system, as the target on which to display the combination, use
/usr/gfx/ircombine -gui -target displayname
|Note: The first time InfiniteReality graphics was initialized, or the first power on of the system with InfiniteReality graphics installed, the video output was defined for the channels available on the workstation. To reinitialize graphics, enter
(/usr/gfx/stopgfx ; /usr/gfx/startgfx) & <Enter>
Note that the parentheses are necessary. Wait for the text port (or system console display) to appear, then input the ircombine command.
Using the Combiner Main Window
In the Combiner main window, click the button for the channel you want to define or modify. See Figure 3-11 for an example of the main window interface.
You might for example, select Ch1 for the first channel. This selection corresponds to Chan1 connections on the InfiniteReality system's I/O panel.
The managed area is the display surface taking up most of the Combiner main window.
Selecting a Video Format for a Channel
When you click a channel button, the Files window appears. You can then select a video format for that channel (see Figure 3-12 for an example).
Figure 3-11. Selecting a Channel Format
The dimensions of the format (for example, 1920 x 1200 for the format file 1920x1200_75.vfo) are the output dimensions, but need not be the input dimensions of the channel's rectangle in the managed area. You can easily resize the rectangle with the mouse or by editing channel attributes.
Once you have defined a channel, the channel's rectangle appears in the managed area of the Combiner's main window. You can move or resize the rectangle as desired. Note that the “Bandwidth Used” scale indicates that memory is in use. See Figure 3-13 for an example of a specified video format.
Figure 3-12. Main Window With a Channel Rectangle Selected
The Combiner interface has many other functions and applications. You can use the Combiner to
define a channel using the on-screen window as input
copy an existing channel format and content to a new channel
align one channel with another
change the video format for a channel (or delete it entirely)
edit the attributes (size, pixel format, etc.) of a channel
select the “field layout” order in which data is scanned from the framebuffer
select and copy a video format stored in a different file
choose an output pixel format for a particular channel
control overlapping rectangles by setting the cursor priority
allocate pixel width and depth for framebuffer fields
set horizontal and vertical phase for a given channel
specify whether sync components have sync enabled by default
modify the brightness characteristics of the monitor
change the default output video gain value for a channel
save a combination of all the channels present in the Combiner's main window and make global changes to them
arrange the pixels (set pixel depth) in the framebuffer to optimize framebuffer output speeds
select the InfiniteReality internal sync (or use an external source that is connected to the “Genlock In” port)
save a video format combination as a default and write it to EEPROM
run a user-defined hardware configuration simulating more RM6 boards than you have (used when an application is too large)
The information in this section is intended only as an introductory overview of the Combiner. For more detailed information on using the Combiner with your Onyx InfiniteReality graphics system, see the InfiniteReality Video Format Combiner User's Guide (P/N 007-3279-00x).
Operating the Optional Video Out Panel
The Video Out Panel is a feature of the VTX and RealityEngine2 graphics subsystems. The Video Out Panel is a software tool that allows you to selectively transmit screen displays and images to the composite or Super VHS (SVHS) monitor and VCR. For example, demos of 3-D graphics, or visual displays of mathematical functions that are displayed on the high-resolution 21-inch monitor, can be captured and displayed on the composite or SVHS monitor and recorded on a VCR.
Starting the Video Out Panel
With the Video Out Panel, you can control the video signals to the CMPST A and B and SVHS A and B ports. Popup menus allow you to select between NTSC and PAL video formats, standard or in-house video synchronization, and standalone or special genlock signals. An Options menu allows you to fine-tune the genlock delay, chrominance phase, chrominance color, and horizontal phase signals.
To start the Video Out Panel, type vo and press <Enter> in a text window. The Video Out Panel Controls menu now appears on your screen (see Figure 3-14).
Figure 3-13. Controls Menu
The Controls menu has buttons that select different video options. These options are described in Table 3-4.
Table 3-4. Options on the Controls Menu
NTSC or PAL. These two buttons
select between the two most common
composite video standards. You
must select the correct format that
matches your composite video
Note: When you select a video
format, the rest of the controls will
default to the most appropriate
setting for that video format.
Genlocking is used to synchronize to
another video signal. This is
normally set to Standalone. The Input
setting is used with special
Other or VCR. These buttons select
the type of synchronization signal to
be sent to the monitor/VCR. This
should normally be set to Other.
Clicking this button causes a window
to appear on the screen. By holding
down the mouse button, you can
move this window over your screen
until it covers the display that you
want to transmit or capture.
As an alternative to the Output Area
button, you can enter the lower left x
and y coordinates in these boxes to
position the output screen precisely.
This display shows the screen
resolution for the video mode you
have selected. It automatically shows
the appropriate mode when you click
NTSC or PAL.
You can control the video signals through the Options menu. Click the Options field in the Controls menu to invoke the Options menu (see Figure 3-15).
Figure 3-14. Options Menu
The Options menu has buttons that control the video signals through the ports. The buttons are controlled by the mouse. Place the cursor on the button, and click and hold down the mouse button. As you move the mouse in an arc, the button turns just like a rotating knob. The options are described in Table 3-5.
In most cases, the Options menu is not needed. For most uses, the default settings are perfectly suitable.
Table 3-5. Options on the Options Menu
Genlocking is synchronized with another
video signal. This control allows you to
minutely control the advance or delay of the
synchronization. The control cycles through
a range of 0 to 63.
Chrominance is a separate signal that
contains color information. It is derived
from the I and Q signals in the NTSC video
format and from the U and V signals in the
PAL video format. This control regulates the
amount of light in each pixel comprising the
R, G, and B signals. It is roughly analogous
to the HUE control on a color television. It
cycles through a range of 0 to 255.
This control is analogous to the TINT
control of a color television. It controls the
color saturation of the display and cycles
through a range of 0 to 255.
This control regulates the horizontal sync,
which is the lowest portion of the horizontal
blanking part of the video signal. It provides
a pulse for synchronizing video input with
output and cycles through a range of 0 to 63.
This section takes you through a sample session with the Video Out Panel. Assume that you have a graphic image or animation sequence running on the 21-inch high-resolution monitor. Size the window in which the display is running so that it doesn't take up the entire screen.
Type the command vout and press <Enter>. The Controls menu appears.
Click either the NTSC or PAL button, depending on the video format of your monitor and VCR. Your choice here determines the default settings for the rest of the controls.
Click the Output Area button. A black rectangle appears on the screen. The rectangle has the correct format, that is, aspect ratio, for either PAL or NTSC. This rectangle is much smaller than the full screen area because NTSC and PAL operate at a much lower resolution than your VTX or RealityEngine2 graphics system does.
Use the mouse to move this window. Move the cursor over the frame of the window and hold down the mouse button. You can now move the window over the portion of the image or animation that you wish to send to the composite monitor or VCR. If the image is too large to be captured in the window, resize the display window, then pull the black output window over the image again.
Once you have covered the display with the output window, you see the demo or image appear in the output window and also on your composite video monitor. If you have a VCR connected, you can begin recording immediately.
|Caution: The Video Out Panel captures images only when the high-resolution monitor is running at its default configuration of |
1280 x 1024, or at the high resolution of 1600 x 1200. While other video resolutions are supported, the images do not appear on the composite or SVHS monitor.
The system should be powered off only for routine maintenance or repair. You can power your system off in either of two ways:
Choose “System Shutdown” from the System menu.
Bring the system down from a shell.
Become superuser by typing /bin/su and pressing <Enter>.
Enter your superuser password, if prompted.
When you see the superuser prompt (#), type /etc/shutdown and press <Enter>.
A message similar to the following appears on the screen:
Okay to power off the system now.
Press any key to restart.
Turn off the power switches for the system and the peripherals in the following order:
printer (if installed)
Reset your system by turning the key switch on the System Controller to the Manager position. Use the scroll buttons to bring up the Reset menu. Press the Menu button to activate the menu, then press the Execute button to reset the system. If the system is completely unresponsive, use only the Reset function, not the main power switch, to reboot your system. If your system responds to input, use the shutdown option in the System Maintenance menu or the halt command.
