1: SGI Graphics Cluster Features and Capabilities
Nodes
An SGI Graphics Cluster node is a rackmounted IA-32 workstation running either
Windows NT or Red Hat Linux. Nodes are of two types: master and channel.
•
The master node is the main compute node in the system; it handles all system
synchronization and provides a network gateway. Each base rack has only one
master node, positioned at the bottom of the rack.
The master node is available in two formats: single-CPU, used in the SGI Graphics
Cluster Series 11, and dual-CPU, used in the SGI Graphics Cluster Series 12. The
master node has standard input and output devices, such as monitor, keyboard, and
mouse. In the SGI Graphics Cluster Series 12, the master node is at the head of the
SGI ImageSync daisy chain.
•
A channel node is the primary graphics element in the system. Each channel node
can drive a single display or can be combined with other channel nodes to drive a
large display.
The short rack can include as many as three channel nodes; the tall rack
accommodates as many as seven channel nodes.
In the SGI Graphics Cluster Series 12, each master and channel node includes a
commercial graphics card and an SGI ImageSync card. These cards are designed to work
together to communicate with the SGI ImageSync network. Chapter 2 describes the
nodes and their components in detail.
Figure 1-3 diagrams an example of connections within an SGI Graphics Cluster system.

1: SGI Graphics Cluster Features and Capabilities
System Networking
Each SGI Graphics Cluster system includes a 100-Base-T Ethernet switch for system
networking; an optional gigabit Ethernet switch can be added, for example, for
connection to a storage area network.
The network switch, which is standard in each SGI Graphics Cluster, is described in the
documentation provided by its manufacturer.
For complete IP address information, see “Channel Names and Addresses” on page 28.
Storage
Each node includes a CD-ROM disk drive, a 3.5-inch floppy disk drive, and a hard disks.
Additional internal storage options are available. In addition, optional networked
storage can be connected via an optional gigabit Ethernet switch.
Audio
The audio on the motherboards is disabled in the SGI Graphics Cluster nodes. The
master node of the SGI Graphics Cluster Series 12 has a SoundBlaster Live! Value sound
card; you can download its manual free from the manufacturer’s web site,
http://www.soundblaster.com.
On the master node of an SGI Graphics Cluster running Linux, the audio card is factory
set to snd-card-0 and the onboard audio is disabled.
Note: For use with the audio card ports on the master node of an SGI Graphics Cluster
Series 12 (or SGI Graphics Cluster Series12 with a customer-added sound card), SGI
supports audio cables no longer than 3 meters. For uses requiring cables longer than 3 m,
you can convert to balanced audio using an unbalanced-to-balanced converter such as
Balance Buddy from Rane Corporation or FP-UBC2 from Radio Design Labs, or do active
conversion to AES digital audio.

16
007-4399-001
Motherboard (System Board)
Onboard Memory
The three DIMM sockets on board allow memory upgrades to a maximum of 1 GB using
256- and 512-MB registered ECC synchronous DRAM (SDRAM) DIMMs. For data
integrity, the default setting of the ECC (error-correction code) function of the memory
system in BIOS is enabled. “Installing and Removing Memory Modules” on page 88 has
instructions for removing and installing DIMMs.
Note: The SDRAM works at 3.3 volts only; 5-volt memory devices are not supported.
The motherboard supports 100-MHz and 133-MHz ECC registered SDRAMs only;
66-MHz SDRAMs are not supported. Only SGI tested memory is supported. See
http://www.sgi.com for a list of supported memory.

AGP
Expansion Slots
The slots are as follows:
•
AGP Pro 50 bus
Developed to support 3D graphic applications, AGP has a 32-bit wide channel that
runs at 66 MHz quad pumped, which translates into a total bandwidth of 1.06
GB/sec (1.056 GB/sec), which is four times the bandwidth of PCI buses (133
MB/sec). AGP also accesses the main memory directly, allowing 3D textures to be
stored in main memory as well as in video memory. Each node has an AGP Pro 50
slot that enables users to install both AGP or AGP Pro cards in the system.
In the SGI Graphics Cluster nodes, this slot is occupied by the graphics card.

Removing a Node from a Rack
A node with a minimum complement of disk drives weighs about 14.5 kg (32 lbs).
Note: Although each SGI Graphics Cluster node is usually under 15.5 kg (34 lbs) it is
strongly recommended that a second person assist you in removing and adding nodes.
To remove a node from a rack, follow these steps:
1.
Locate a work surface that can accommodate the node.
If you are returning the node to Silicon Graphics, have ready the packaging for
returning the node to Silicon Graphics. This packaging is available from SGI field
service offices.
Warning: When adding or servicing equipment in the rack, do not pull out more
than two nodes at a time.
2. Pull the node out of the rack by following all the steps in “Pulling a Node Out of the
Rack” on page 39.
If you are replacing the node immediately, you can leave the external
SGI ImageSync cable connected to the next node. If you are not replacing the node
immediately, connect the SGI ImageSync cable to the next node in the series.
Remove and store the unused SGI Image Sync cable. The nodes of the SGI Graphics
Cluster Series 12 must be daisy-chained for SGI_ImageSync to function.

Attaching Sliders with Node Screws
Attaching Slide Rails to a Rack
To attach slide rails to a rack so that you can add a new node, follow these steps:
1.
Have ready the two slide rails and their hardware, including the two brackets. The
two inner parts (sliders) are attached to the node.
2. Prepare the rack as follows:
■
Power off the rack with its circuit breaker; unplug the rack.
■
If necessary for easier access, pull out the node that is next to the space where
you want to attach the new slide rails. Pull out the rack’s anti-tip shelf; see
Figure 4-5 on page 42.
Warning: Be sure to pull out the anti-tip shelf before pulling out a node.
Failure to do so can result in the rack tipping over.
■
50
Remove the screws that will interfere with the slide rails.
007-4399-001
Attaching Slide Rails and Sliders
■
To accommodate a 4U node, measure 7 inches (12 holes).
■
Remove the screws from the inside holes on the rear rails, and replace them in
the outside holes.
■
Tighten the top and bottom screws by hand and realign them. The outside of
the front rail should be 69.8 cm (27.5 inches) to the outside of the back rail.
■
Torque the screws to 32 in-lbs.
3. Attach the slide rail mounting brackets to the slide rails, as follows.
■
Place two screws in the first and third holes on the front of the outer slide rail,
and align the bracket so the screws protrude through the slotted hole on the
bracket. Place the flat washer, lock washer, and nut on the screw.
■
Place two screws through the two holes on the back end of the slide rail, and
align the bracket so the screws protrude through the slotted hole. Place a flat
washer, lock washer, and nut on the screws.
■
Push both brackets towards the center of the slide rail so both outside screws
are against the end of the slotted opening in the bracket. Use a nut driver and
screwdriver to tighten the screws.
■
Repeat these steps for all slide rails needed (one set per system).
4. Install the slide rails in the rack, as follows (see Figure 4-12):
007-4399-001
■
At the front of the rack, place a shoulder washer on four screws (10-32 x 3/8),
align the slide to the proper rail holes, hold a clip nut on the backside of the
slide, and place a screw (with shoulder washer) through the front of the rail.
■
Thread the screw into the clip nut until the shoulder washer engages the hole in
the rail. Hold out and up on the slide while hand-tightening the screws.
■
Place the second screw the same way.
■
At the back of the rack, repeat these steps for the back of the slide.
■
Repeat for the other slide rail of the pair. When all slide rails are installed,
torque all screws to 32 in-lbs. Do not overtighten the screws.

Installing and Removing Memory Modules
The three 168-pin sockets on the motherboard support SDRAM registered ECC DIMMs.
You can install 256-MB or 512-MB (single- or double-density) DIMMs for a maximum of
1 GB of system memory. Each DIMM socket is independent from the others; you can
install DIMMs with different capacities to form different configurations.
Note: The SDRAM works at 3.3 volts only; 5-volt memory devices are not supported.
This motherboard supports 100-MHz and 133-MHz SDRAM. However, they cannot be
used at the same time in the system.
Warning: Using both 100-MHz and 133-MHz SDRAM together might cause your
system to malfunction. For a qualified DIMM vendor list, please contact your SGI
representative.

As a general rule, an error message of Press F1 to continue is caused by a
configuration problem (see “Changing BIOS Settings” on page 94) or by a loose cable (see
“Checking Cabling” on page 94). An equipment malfunction is more likely to cause a
fatal error, that is, complete system failure.
If you perform the corrective steps in Table 6-1 and still receive an error message, the
cause may be an equipment malfunction. If you are sure that your configuration values
are correct and your battery is in good condition, the problem may be a damaged or
defective chip. In either case, contact an authorized service center for assistance.
007-4399-001
93
6: Troubleshooting
Changing BIOS Settings
The BIOS utility allows you to view your system’s configuration settings. The system is
configured at the factory. You do not need to enter the BIOS when starting the computer
unless you receive an error message.
The BIOS program loads configuration values into the battery-backed nonvolatile
memory called CMOS RAM, a memory area that is not part of the system RAM. If you
repeatedly receive error messages, the battery may be bad. In this case, the system cannot
retain configuration values in CMOS. Ask a qualified technician for assistance.
To enter the BIOS, press Ctrl Alt Esc simultaneously to enter the BIOS setup menu.
Checking Cabling
On rare occasions, cables are damaged from frequent or careless uncabling and recabling
operations. Make sure that the pins on the connector are not bent.
To check internal cabling, power off the node and remove the node cover by following
all instructions in “Preparing a Node for Component Replacement or Addition” on
page 37. Check that the internal cables are securely attached to the correct connectors.
Solving Disk Problems
If you cannot access a new disk, the disk may not be properly formatted. Consult a
system administration guide for disk formatting instructions; see “System
Administration References” on page 36.

6: Troubleshooting
Troubleshooting Node Problems
This section explains node problems and suggests solutions.
•
The pconsole program starts, claims to attach, and goes away.
Check the network cable on the 10-Base-T or 100-Base-T Ethernet switch to ensure
that the master channel is plugged in and active.
•
When a node is powered on, it opens the CD-ROM tray
The CD-ROM drive has a broken tray switch. Replace the CD-ROM drive.
•
When a node is powered on, its screen remains blank and the splash screen is not
displayed
Press the reset switch on the node.
If the node still maintains a blank screen, no sync is present. Power off the node,
disconnect it, pull it out of the rack (see “Pulling a Node Out of the Rack” on
page 39), and ensure that the graphics card is properly seated in the AGP slot.
Warning: Be sure to pull out the anti-tip shelf before you pull out a node. Failure
to do so can result in the rack tipping over. Never pull out more than two nodes at
a time.
If the problem remains, call your service provider.
•
When a node is powered on, it fails to come up and the power indicator is dim.
Power off the node, disconnect it, and pull it out of the rack (see “Pulling a Node
Out of the Rack” on page 39). Reseat the SGI ImageSync card.
If the problem persists, verify that the floppy power cable is correctly connected and
is not offset by one pin.
•
During use, a monitor goes into standby mode.
Remove the monitor cable and attach it to a different system. If the monitor comes
back on, reattach the monitor cable to the original node. If the monitor remains on,
replace the VGA cable; it may have a broken wire.
If the problem persists, attach a different monitor and cable to the node to verify the
problem. Reboot the node to see if the problem persists.

Troubleshooting Sound Card Problems (SGI Graphics Cluster Series 12 Only)
•
When the node is powered on, no system disk is found.
Power off the node, remove cables, pull out the anti-tip shelf, and pull out the
affected node (see “Pulling a Node Out of the Rack” on page 39). Reseat the SCSI
cable connector onto the hard drive.
Troubleshooting Sound Card Problems (SGI Graphics Cluster Series 12
Only)
For sound card problems, consult the manual for the SoundBlaster Live! Value sound
card. You can download the manual for this card free from the manufacturer’s web site,
http://www.soundblaster.com.
This section explains sound card problems and suggests solutions.
•
On a Linux system, the sound card does not function.
Verify that the sound card’s master and PCM channels are not muted and that gains
are raised. See http://www.alsa-project.org for other troubleshooting advice.
•
On a Windows NT system, the network on the master channel stops working.
Ping the master node and other nodes. If the master node can ping itself but not
other nodes, power off the node, disconnect it, pull it out of the rack (see “Pulling a
Node Out of the Rack” on page 39), and remove the sound card.
Warning: Be sure to pull out the anti-tip shelf before you pull out a node. Failure
to do so can result in the rack tipping over. Never pull out more than two nodes at
a time.
Reattach cables and boot up. Verify network functionality.

Node Port Pinouts
Audio Ports
The audio on the node motherboards is disabled in the SGI Graphics Cluster. The master
node of the SGI Graphics Cluster Series 12 has a commercial audio card.
An SGI Graphics Cluster node uses a 3.5 mm mini jack stereo microphone port, an analog
line-level audio input port, and an analog line-level audio output port.
For use with the audio card ports on the master node of an SGI Graphics Cluster Series12,
SGI supports audio cables no longer than 3 meters. For uses requiring cables longer than
3 m, you can convert to balanced audio using an unbalanced-to-balanced converter such
as Balance Buddy from Rane Corporation or FP-UBC2 from Radio Design Labs, or do
active conversion to AES digital audio.
For port information for the sound card on the SGI Graphics Cluster Series12 master
node, see the manufacturer’s manual for the product, which is a SoundBlaster Live!
Value sound card. You can download the manual for this card free from the
manufacturer’s web site, http://www.soundblaster.com.

Shielded Cables
The SGI Graphics Cluster is FCC-compliant under test conditions that include the use of
shielded cables. Your cluster and any peripherals you purchase from SGI have shielded
cables. Shielded cables reduce the possibility of interference with radio, television, and
other devices. If you use any cables that are not from SGI, ensure that they are shielded.
Telephone cables do not need to be shielded. Twisted-pair Ethernet cables are not
shielded.
007-4399-001
113
B: Regulatory Information
Monitor cables supplied with your system use additional filtering molded into the cable
jacket to reduce radio frequency interference. Always use the cable supplied with your
system. If your monitor cable becomes damaged, obtain a replacement cable from SGI.
Electrostatic Discharge
SGI designs and tests its products to be immune to the effects of electrostatic discharge
(ESD). ESD is a source of electromagnetic interference and can cause problems ranging
from data errors and lockups to permanent component damage.
It is important that you keep all the covers and doors, including the plastics, in place
while you are operating the system. The shielded cables that came with the SGI Graphics
Cluster and its peripherals should be installed correctly, with all thumbscrews fastened
securely.
An ESD wrist strap may be included with some products, such as memory or PCI
upgrades. Use the wrist strap when installing these upgrades to prevent the flow of static
electricity; it should protect your system from ESD damage.
