The Silicon Graphics Fuel visual workstation is installed in the system enclosure as shown in Figure 3-1. The enclosure provides a total of five card slot openings: One for the graphics module and four for PCI cards. The enclosure also provides space for three hard disk drives and two removable media drives. These drives are housed in three drive cages: two 3.5-in. cages and one 5.25-in. cage.

The Silicon Graphics Fuel visual workstation IP34 system board is attached to the side of the chassis as shown in Figure 3-2. The system board provides connectivity to all of the system components. The system board features include:

The Silicon Graphics Fuel visual workstation is available with either a 500-MHz R14000A processor with 2 MB of secondary cache or a 600-MHz R14000A processor with 4 MB of secondary cache. The unit supports a maximum of one processor. The processor and cache are mounted on a processor-integrated multi-module (PIMM) board, which is connected to the system board via a special connector, as shown in Figure 3-3.

The workstation is configured with a minimum of 512 MB of memory and a maximum of 4 GB of memory. Your system uses double data rate synchronous dynamic random access memory (DDR SDRAM). The DIMMs used in your workstation are compatible with the DIMMs used in Origin 300, Origin 3000, and Onyx 3000 systems. The DIMMs used in your workstation are not compatible with the DIMMs used in Octane, Octane2, O2, O2+, Origin 200, Origin 2000, or Onyx2 systems.

The memory DIMMS are installed in four DIMM sockets on the motherboard. The DIMM sockets are numbered 0 through 3 (refer to Figure 3-4). The sockets are grouped into two banks of two DIMMs each: DIMM pair 1 and DIMM pair 2.

The following configuration rules apply to the memory banks and DIMMs in your system:

For information on removing or installing memory DIMMs, refer to “Installing or Removing a Memory DIMM” in Chapter 4.

The Silicon Graphics Fuel visual workstation supports up to 3 internal hard disk drives. The following drives are available:

These drives provide the unit with a minimum of 18 GB of internal storage and a maximum of 219 GB of internal storage.

The hard disk drives in the workstation are installed in two 3.5-in. drive cages, as shown in Figure 3-5. The lower bay is mounted on a hinge and can be swung out of the chassis for service.

The disks are numbered 1 through 3, with 1 being the bottom disk in the lower bay and 3 being the bottom disk in the upper bay. The SCSI ID number of each disk must correspond with these drive numbers.

For information on removing or installing an internal hard disk drive, refer to “Installing or Removing Internal Hard Disk Drives” in Chapter 4.

Your workstation supports up to 2 internal removable media drives. The following drives are supported:

The removable media drives are installed in the 5.25-in. drive bay, as shown in Figure 3-5. These drives are optional components, and can be ordered from your SGI sales representative.

For information about installing and removing a removable media drive, refer to “Installing or Removing a Removable Media Drives” in Chapter 4.

The graphics module is located near the bottom of your workstation, as shown in Figure 3-7. It is made up of a metal cover, the VPro graphics board and the optional Dual Channel Display daughterboard. The metal shell protects the graphics board and optional daughterboard and shields them from electrical interference.

The VPro graphics board has the following features:

The optional Dual Channel Display daughterboard supplies two additional DVI-I monitor ports. The daughterboard connects to the underside of the VPro graphics board and allows you to display data across two monitors at once. For more information about the optional Dual Channel Display daughterboard, contact your SGI sales representative.

Figure 3-8 shows the I/O ports of the VPro graphics board and optional Dual Channel Display daughterboard.

For more information on the VPro graphics board and Dual Channel Display I/O ports, refer to “VPro Graphics Board I/O Port Specifications” in Appendix A.

The Silicon Graphics Fuel visual workstation supports a maximum of four 3.3-volt PCI boards. The PCI boards are installed in PCI slots on the motherboard. The PCI slots are divided into two busses, PCI bus E and PCI bus F (refer to Figure 3-9).

The following PCI boards are currently supported:

The power supply for the workstation is located in the top rear quadrant of the chassis, as shown in Figure 3-10.

The power supply provides up to 430 watts of power to the motherboard, internal hard disk drives, removable media drives, and other optional components installed in the enclosure. For detailed information about the power supply specifications, refer to Appendix A, “Technical Specifications”.

The Silicon Graphics Fuel visual workstation uses a system of fans and ducts to cool the internal components. The cooling system is made up of the following components:

Figure 3-11 shows the location of each of these components.

Various optional components, peripherals, and upgrades are available for the Silicon Graphics Fuel visual workstation. If you have questions about any of these items, contact your SGI sales representative.
