This chapter contains the following sections:
The Silicon Graphics 320 visual workstation contains three PCI card option slots on two PCI buses—one half-length 32-bit-wide slot on bus:0 and two full-length 64-bit-wide slots on bus:1. This chapter tells you how to install and remove PCI option cards. For maximum performance, install cards in bus:1 slots first.
If you purchased a SCSI PCI option card and internal SCSI hard drives, see Chapter 4, “Internal Drives,” for information on installing or removing the drives and attaching or disconnecting the internal SCSI cable.
 | Note: The Silicon Graphics 320 visual workstation supports 3.3-volt PCI cards only. It does not support 5.0-volt PCI cards. Also, the workstation does not support PCI graphics cards. Multi-head capabilities will be available in a future release of Windows NT. |
Shut down the system and turn off the power. For detailed instructions, see “Shutting Down the System”.
Unplug the power cord from the back of the system.
Remove the side cover. For detailed instructions, see “Removing the Side Cover”.
Touch a metal part of the chassis with your hand to discharge any static you might be carrying.
If there is a blank plate covering the PCI slot opening, remove it, as shown in Figure 5-1.
Insert a Philips screwdriver into the opening opposite the screw and remove the screw.
Pull out the plate.
Save the plate. In the future, if you remove the PCI card and leave the slot empty, you will need to reinstall the plate.
Install the new card, as shown in Figure 5-2.
Insert the card into the slot.
Insert a Philips screwdriver through the opening opposite the screw hole and insert and tighten the screw.
If you are installing a SCSI PCI option card and internal drives, see Chapter 4, “Internal Drives” for information on installing the drives and attaching the internal cable.
Replace the side cover. For detailed instructions, see “Replacing the Side Cover”.
Reattach the power cord.
Power on the system. For detailed instructions, see “Turning On the System”.
Use the Windows NT Diagnostics panel to verify that the system recognizes the PCI card you installed. To open the panel, select Start > Programs > Administrative Tools > Windows NT Diagnostics. Click the Resources tab and look down the Type list to find the recognized PCI cards.
If the system does not recognize the card, shut down and reopen the system. Make sure the card is securely seated in the socket. Close and reboot the system. If the system still does not recognize the card, it may be faulty. Contact your support representative.
Shut down the system and turn off the power. For detailed instructions, see “Shutting Down the System”.

Insert a Philips screwdriver into the opening opposite the screw and remove the screw.
Grasp the card and gently pull it out of the slot.
If you are removing a SCSI PCI card and have external devices attached, disconnect the device cable from the external connector. If internal SCSI hard drives are attached, see “Disconnecting the SCSI PCI Option Card Internal Cable” for information on disconnecting the cable from the internal drives and card.
If you are not installing another card in the slot, install a blank panel, as shown in Figure 5-4.
Replace the side cover. For detailed instructions, see “Replacing the Side Cover”.
Reattach the power cord.
Power up the system. For detailed instructions, see “Turning On the System”.
If you ordered a flat panel display monitor when you purchased your Silicon Graphics 320 visual workstation, the option card is preinstalled. You do not need to install it. If you ordered the Silicon Graphics 1600SW flat panel monitor separately from the workstation, you need to install the option card before attaching the monitor.
