This chapter describes the removal of the hardware portion of the Silicon Graphics Octane2 Duo upgrade.
There is no need to remove the software portion of the Duo upgrade. It may easily be deactivate, as described in “Configuring a Duo System to Function as a Dual Head System” in Chapter 5.
 | Note: If you simply wish to use a Duo system as a Dual Head, single-user system—whether on a temporary or a long-term basis—there is no need to remove the hardware. You may simply deactivate the Duo software, as described in “Configuring a Duo System to Function as a Dual Head System” in Chapter 5, and disconnect the secondary keyboard and mouse. |
The removal process consists of the following sections:
This chapter relies heavily on your Octane2 Workstation Owner's Guide. Make sure you have it handy before proceeding with the removal.
Before installing or removing any hardware, you should first perform a complete backup of your system.
After making a backup you should shut down the operating system and power off the workstation.
The memory, PCI module, and PCI card removal require the use of the static dissipating wrist strap that came with your upgrade kit.
The instructions for removing an internal drive may be found in Chapter 7, “Installing and Removing Internal Drives and Front Module Parts,” in your Octane2 Workstation Owner's Guide. The steps involved in the process are outlined below, along with references to specific portions of Chapter 7 in your Octane2 Workstation Owner's Guide.
 | Caution: If you added new users' home directories, moved home directories of existing users, or configured swap space to the option drive, or if you used the option drive for any other purpose, removing it may make your system completely or partially unusable. |
| Note: You should unmount the option drive before removing it. Go to Toolchest > System > System Manager > Hardware and Devices > Disk Manager. Select the drive you wish to unmount, click the Unmount button, and follow the directions. |
To remove the option drive, follow these steps:
Shut down and power off your workstation, as described on page 161 of your Octane2 Workstation Owner's Guide.
Remove the lock bar and the front bezel from your workstation, as described on pages 162 through 164 of your Octane2 Workstation Owner's Guide.
Remove the drive that was installed as part of the Duo upgrade (it will be in either the middle bay or the upper bay), as described on pages 170 and 171 of your Octane2 Workstation Owner's Guide.
Note: The lower bay is used for the system drive, and should be left in place. Reinstall the appropriate blank panel (that is, the middle or upper one) in the front bezel, as described on pages 171 and 172 of your Octane2 Workstation Owner's Guide.
Reinstall the front bezel and the lock bar, as described on pages 195 and 196 of your Octane2 Workstation Owner's Guide.

Caution: The components inside your workstation are extremely sensitive to static electricity. Always wear a wrist strap when you replace parts inside your workstation. Remove the system module, as described on pages 36 through 40 of your Octane2 Workstation Owner's Guide.
Caution: Be sure to place a cap over each of the two compression connectors on the system module, as described on page 40 of your Octane2 Workstation Owner's Guide. For more information about compression connectors, refer to Appendix A, “Care and Cleaning of Compression Connectors”, in this manual. Remove the memory that was installed as part of the Duo upgrade, as described on pages 47 through 52 of your Octane2 Workstation Owner's Guide.
Reinstall the system module, as described on pages 53 through 56 of your Octane2 Workstation Owner's Guide.
Reconnect the cables to the system module, as described on page 57 of your Octane2 Workstation Owner's Guide.
Reinstall the lock bar, as described on page 59 of your Octane2 Workstation Owner's Guide.

Your additional system memory is now removed.
The instructions for installing the PCI card and PCI module may be found in Chapter 4, “Installing and Removing PCI Boards,” in your Octane2 Workstation Owner's Guide. The steps involved in the process are outlined below, along with references to specific portions of Chapter 4 in your Octane2 Workstation Owner's Guide.
| Note: In addition to the mouse and keyboard port, the Duo PCI card contains an Ethernet port. If you were using the Ethernet port, removing the Duo PCI card could affect your system connectivity and operation. |
| Note: Before removing the PCI module, you should verify that it does not contain any PCI cards other than the Duo PCI card. |
To remove the PCI card and PCI module, follow these steps:
Shut down and power off your workstation, as described on page 72 of your Octane2 Workstation Owner's Guide.
Attach a wrist strap to your wrist and to a ground, as described on page 74 of your Octane2 Workstation Owner's Guide.
Caution: The components inside your workstation are extremely sensitive to static electricity. Always wear a wrist strap when you replace parts inside your workstation. Remove the PCI module from the Octane2 chassis, as described on pages 75 through 78 of your Octane2 Workstation Owner's Guide.
Caution: Be sure to place a cap over the compression connector on the PCI module, as described on page 77 of your Octane2 Workstation Owner's Guide. For more information about compression connectors, refer to Appendix A, “Care and Cleaning of Compression Connectors”, in this manual. Open the PCI module, as described on page 78 of your Octane2 Workstation Owner's Guide.
Remove the PCI board, as described on pages 89 through 93 of your Octane2 Workstation Owner's Guide.
Place the PCI board in a static bag for safe storage.
Install the PCI module blanking panel using the two screws that held the PCI module in place.
