About This Guide

Welcome to the user’s guide for the Silicon Graphics® Prism™ Deskside visualization
system. Your new deskside system offers one or two graphics pipes and a
high-bandwidth architecture in a convenient free-standing deskside tower chassis. The
system is available in a variety of configurations and can be upgraded to meet your
future needs.

This guide shows you how to set up, use, and troubleshoot your system. Go to the first
chapter for quick start information, or use the table of contents to find the topic area you
need. This guide is provided for all end-users, administrators and technical support staff.
Many of the hardware tasks are relatively simple and require minimal computer
knowledge. A few tasks are more difficult; they are easier to perform if you have some
computer hardware experience.

This guide is written for owners, system administrators, and users of the Silicon Graphics
Prism Deskside visualization system. It is written with the assumption that the reader
has a good general knowledge of computer graphics and computer operations.

Important Information

2: System Overview

System Node Board

The system is powered by an scaleable system node board. The system node board
provides a mounting point and connectivity for the processor(s) and memory DIMMs.
The node board connects to the interface board via two connectors on its underside.
These boards are not customer replaceable.

Processors

The system is available with one or two 64-bit Intel processors. These processors are
available in different clock speeds and cache sizes. Each processor has on-board cache
memory and external cache memory. Each processor is mounted on the system node
board under a heat-dissipating protective cover. The processors are not customer
replaceable.

Memory DIMMs

The system is configured with a minimum of four DIMMs (2 GB) of memory and a
maximum of 12 DIMMs (24 GB) of memory. Your system uses double data rate
synchronous dynamic random-access memory (DDR SDRAM). The DIMMs are always
installed in groups of four. Each DIMM in a group of four must be the same speed and
memory capacity. Different DIMM groups may have different speed and memory
capacity values. “Installing or Removing a Memory DIMM” in Chapter 3 provides
additional detail on memory DIMMs including removal and replacement rules and
procedures. Figure 2-3 shows the memory DIMM group placement.

need to install optional ImageSync functionality in your system.

007-4772-002 31

2: System Overview

PCI Buses

Each deskside system supports eight 64-bit, PCI-X slots which are divided into four
buses, as shown in Figure 2-10. Note that the top two slots of bus 1 are always occupied
by the static I/O daughter board and the base I/O PCI card. The system’s base I/O boar d
always occupies bus 1, slot 1, and the static I/O daughter board is permanently installed
in the top slot (bus 1, slot 2). The static I/O daughter card provides the USB, L1 USB,
serial console, and ImageSync connectors for the deskside unit.

The remaining six slots are available for other optional PCI/PCI-X boar ds. Each bus can
support card speeds of up to 133 MHz. The slots are divided into buses, as shown in
Figure 2-10.

• PCI Bus 1 has one usable slot, which always contains the base I/O board.

• PCI Buses 2, 3, and 4 each have two slots.

Follow these general rules when installing PCI and PCI-X boards on the PCI-X buses:

• A void placing high and low speed cards on the same bus. This forces the high speed
card to run at the same speed as the slower card. For example, placing a 100-MHz
board on the same bus as a 66-MHz board forces the 100-MHz board to run at the
slower speed.

• Avoid placing storage and network boards on the same bus. These types of boards
use large amounts of bandwidth. Placing both types on the same bus can cause the
system to exceed the bandwidth of the bus.

• Spread the PCI boards across the buses as evenly as possible. For example, if you
have three PCI boards and three available PCI buses, install one board on each bus.
If you must install more than one board on a bus, group the boards by speed.

Installing or Removing a Memory DIMM

The Silicon Graphics Prism Deskside visualization system is configured with a minimum
of 2-GB of on-board system memory and a maximum of 24 GB of memory. Memory is
contained on small cards that are referred to as DIMMs (dual inline memory modules).
Each deskside system can contain four, eight, or twelve DIMMs installed in DIMM slots
located on the system node (mother) board.

The memory DIMM sockets are divided into three 4-DIMM groups (gr oups 0, 1, and 2).
The instructions in the following sections assume that you know the correct slots in
which to install the memory DIMMs. For information about DIMM configurations and
placement rules, continue reading the rest of this section.

Note: If you have not already done so, remove the right side of the enclosure to access
the DIMMS. Refer to “Preparing the System for Service” on page 44.

Instructions are provided in the following sections:

Installing or Removing a Memory DIMM

•“Removing a DIMM” on page 59

•“Verifying Memory Installation” on page 63

These twelve DIMM slots are organized into three groups of four DIMMs each, as shown
in Figure 3-8 on page 58 . DIMMs are installed one per DIMM slot, and four at a time
(group of four). Follow these guidelines when installing DIMM groups:

• Memory is increased or decreased in four-DIMM group increments only.

• Each of the four DIMMs that make up a DIMM group must be the same memory

size and speed; however, different groups of DIMMs can differ in memory size or
speed.

• The first four DIMMs (group 0) must be in place for the base module to operate

properly.

• Mixing DIMM groups with different access speeds will cause the memory bus to

default to the speed used for the slowest group.

• The maximum bus speed for a completely full set of DIMM memory slots (three

installed groups), defaults to 100 MHz or 133 MHz, depending on the type of
DIMMs installed.

007-4772-002 57

3: Maintenance and Upgrade Procedures

Note: The DIMMs used in the Silicon Graphics Prism Deskside visualization
platform are not compatible with DIMMs used in the Origin 200, Origin 300, Origin
350 series, Origin 2000, Origin 3000, SGI 3000 series, SGI 2000 series, Onyx systems,
Fuel, Octane Octane2, O2, O2+, or Tezro systems.
