## Chapter 4. Troubleshooting

This chapter contains information on what to do if you experience problems with your system or installation. Each section describes a problem and provides instructions on how to solve the problem. Product support information is at the end of this chapter.

## Accessing hinv

Using the `hinv` command accesses information about the number of channels and their configurations that exist in an OCTANE workstation with a Personal Video board installed.

The listing provided by `hinv` includes the following information:

- the confirmation (or lack) of the presence of an OCTANE Personal Video board

- the recognition of a video format successfully loaded into the system

Follow these steps to use `hinv`:

1. Go to the Toolchest.

2. Open a shell: choose Desktop > UNIX Shell.

3. On the command line, type `hinv`

4. Look for a line similar to this: `Personal Video: unit 1, revision 1.0`

5. If you do not see this line, go to Chapter 3, “Removing the OCTANE Personal Video Board”, and follow the instructions for powering off the OCTANE workstation and removing the XIO module. Then follow the installation instructions in Chapter 1, “Installing the OCTANE Personal Video Board” to be sure the Personal Video board was properly installed.

6. Run `hinv` again. If your Personal Video board is not recognized, call your authorized service provider.

## Checking Connections and Installation

Use the following troubleshooting checklist to solve an installation problem:

- The power cables are connected to the workstation and the monitor.

- The camera or other cable connector at the chassis I/O panel is seated and the thumb screws are tightened.

- The audio cable is connected to both the system module and Personal Video board when using the O2Cam camera.

- Any video cables are completely seated.

- The OCTANE Personal Video board and graphics board are properly seated in the chassis. Follow instructions in Chapter 1 for opening the chassis, reinstalling the XIO module, and powering on the workstation.

- The flex cable connections to the graphics board are completely seated. Follow the directions in Chapter 1 from powering off the workstation to connecting the flex cables from the OCTANE Personal Video board to the graphics board. Then follow the instructions to seat the flex cables through powering on the workstation.

- The XIO module is seated and the I/O panel on the OCTANE Personal Video board is relatively flush with the chassis. If not, follow the instructions in Chapter 1 from powering off the workstation through removing the XIO module, and see if an XIO compression connector cap is on any XIO compression connector. If so, remove the cap, and follow the instructions in Chapter 1 for replacing the XIO module.

- The graphics boards are inserted toward the interior of the workstation.

- The appropriate operating system and software have been installed. See the software CD and release notes that came with your shipment.

- The monitor is appropriate for your OCTANE workstation.
