The Silicon Graphics 320 visual workstation measures approximately 9" wide by 17" high by 17" deep. Removable media drives are at the front top of the enclosure for easy access in desktop or deskside arrangements. Slots for PCI options, disk drives, memory modules, and processor modules are accessible by removing the side cover. Cooling is achieved by two internal fans plus a fan in the power supply.

The Silicon Graphics 320 visual workstation power supply is switch-selectable for 110 V versus 220 V AC power. The supported AC range for each switch setting is:
Switch | Voltage | Voltage |
| Current |
|---|---|---|---|---|
110 | 100 V | 120 V | 50/60 Hz | 4.7 A |
220 | 200 V | 240 V | 50/60 Hz | 2.5 A |
The following table contains information about the Silicon Graphics 320 visual workstation system board ports and buses.
Table A-3. System Board Specifications (continued)
Port or Bus | Description |
|---|---|
Processor bus | One or two Intel Pentium II Slot 1 processors with 100 MHz Front Side Bus (FSB). Dual processor systems must have both processors at the same frequency. Uniprocessor systems must have a terminator module in the second processor slot. |
Memory configuration | The minimum memory configuration is 128 MB using six 4 M x 48 DIMM modules. The maximum memory configuration is 1GB using 12 16 M x 48 DIMM modules. DIMMs must be added in groups of six. |
Ultra DMA IDE | One UltraDMA/33 IDE channel for one internal 3.5" x 1" system drive and one internal option 3.5" x 1" disk drive. |
Ultra DMA IDE | One UltraDMA/33 IDE channel for 5.25" x 1.6" CD or DVD drive and one optional 3.5" x 1" removable media drive. |
FDI | One Floppy Drive Interface for a 3.5" x 1" floppy drive. |
USB | Two Universal Serial Bus (USB) ports. |
Monitor port | VGA connector to CRT or analog-interface flat panel monitor. Supports monitor ID and control via DDC2B interface. |
Display option | One optional digital interface connector flat panel monitor port supporting the Silicon Graphics 1600SW flat panel monitor. |
IEEE 1394 port | Two IEEE 1394 connectors at 400 Mbps. |
Serial port | One RS-232 serial port with separate DMA channels for input and output. Each channel is capable of up to 115 Kbaud and is full duplex. |
Parallel port | One IEEE 1284-compliant parallel port. |
Ethernet port | One 10/100 Mb auto-sensing Ethernet interface. |
Analog audio ports | The audio subsystem has two input channels that can be sourced from the microphone input; the stereo line-level inputs, or the internal CDROM drive analog audio outputs. The audio subsystem has two output channels that drive the stereo line-level outputs, and the stereo variable-level headphone/speaker output. |
Analog video ports | The video subsystem has two channels and two signal formats. The input channel can take data from a composite input or an Y/C (S-Video) input, and the output channel can send data to a composite output and a Y/C (S-Video) output simultaneously. |
PCI Bus | There is one PCI 64-bit 33MHz PCI bus in the system that supports the PIIX4 IDE interface and the three PCI slots. The bus has a peak bandwidth of 266 Mbps in 64-bit mode, or 133 Mbps in 32-bit mode. There are read-ahead and write-behind buffers that help reduce PCI latency to memory. |
