2: Hardware Overview
The SGI 1200 server has four hard disk bays and a midplane for easy drive removal,
replacement, and chassis monitoring. It supports hot-swap drives with an optional SGI
1200 server RAID controller. Two removable media drives are supported.
Figure 2-1 shows a top view of the chassis internals for an SGI 1200 server with a
midplane and optional RAID controller.
In Figure 2-1, note the following:
• A dual processor motherboard (in single processor systems the secondary processor
location must have a terminator board installed)
• The DIMM locations are numbered from one to four moving from left to right.
• The midplane is connected to the optional RAID controller by way of a SCSI cable:
– The optional RAID controller PCI card enables hot-swap capability.
– In configurations with an SCA midplane but without the RAID controller, the
drivebayshavenohot-swapdataredundancy.

Processors
The SGI 1200 server motherboard can be populated with up to two Intel Pentium III
processors. The processors on the motherboard must be rated at the same clock speed.
Contact your sales or customer support representative for information on upgrading
your server’s processors.
Memory
The motherboard supports from 128 MB to 2 GB of 100 MHz PC/100 SDRAM memory.
The system supports only error correcting code (ECC) memory. Contact your sales or
system support representative for server memory upgrades.
I/O Subsystem
Figure 2-3 shows the basic cabling routes. Moving from left to right:
8 007-4248-001
Theory of Operations
• The floppy controller on the motherboard connects to the floppy drive.
• The IDE controller on the motherboard connects to the CD-ROM drive.
• The Ultra-2 SCSI controller on the optional PCI-based RAID controller connects to
the midplane providing hot-swap RAID capability for four or five hard drives.
Figure 2-4 shows cabling routes without the optional PCI-based RAID controller:
• Wide Ultra2 LVD SCSI capability on the motherboard connects to the midplane
providing high performance disk I/O for hard drives for customers who do not
require hot-swap capability with data redundancy.
External connections are not shown. All configurations support an optional Ultra SCSI
connector for external SCSI devices. See Figure 2-11 for the location of this connector on
the back panel and Table 4-1 for additional information.

Midplane
The SCA midplane on the SGI 1200 server provides easy hard drive removal and
replacement. Adding a RAID controller supports hot-swap capability for SCA-2 hard
drives using Ultra2 SCSI technology on a single channel. All bus termination and SCSI
ID selection for SCA hard drives is handled automatically by the midplane.
Note: The midplane does not support single ended SCSI devices.
The SCA midplane uses Qlogic’s GEM processor to implement the SAF-TE (SCSI
Accessed Fault Tolerant Enclosure) specification. The processor monitors the removal
and replacement of Ultra-2 SCSI SCA hard drives, scans the SCSI bus for errors, and
senses chassis over-temperature and failed fan conditions.
The following SCSI error conditions are indicated as failures:

• hard drive not responding to low level SCSI commands
Figure 2-5 shows the SCSI IDs that the midplane assigns. The midplane itself uses SCSI
ID 9.

Temperature sensors on the right and left side of the midplane monitor the chassis
temperature. When the sensors detect internal chassis temperatures above 50 degrees C
(equipment damaging conditions), the midplane issues a signal that causes the amber
Global Failure LED on the front panel to light.
The chassis fans are also monitored, and a fan failure causes the Global Failure LED to
light.

Chassis LEDs, Buttons and Connectors
There are two push buttons and several LEDs on the right hand side of the SGI 1200
server front panel. The following sections provide information about the buttons and
LEDs on the front and back panel, and information about error conditions that the LEDs
can indicate. The information in this section can help you make a quick visual inspection
of the status of the hard drives, network connections and internal components of your
SGI 1200 server.
If theamber Global Failure LED that you can viewthrough the front cover does light, you
can use the information in this section, and Chapter 5 to troubleshoot the failure source.

Front AC Power Push Button
Pressing this button powers on the SGI 1200 server. If you decide that you don’t want to
power up the SGI 1200 server, press the button again to immediately shut down the
system. The blue LED will blink briefly and the server shuts down before the BIOS or
operating system are initialized.
When the SGI 1200 server is operating, holding this button for five seconds issues a
shutdown command to the system.
007-4248-001 13
2: Hardware Overview
Reset Push Button
Warni ng : The SGI 1200 server continues to have AC power inside the chassis even
after the front power push button has been pressed to power down the SGI 1200
server. As long as the AC power cord is connected, the power supply supplies DC
power so that the motherboard can be controlled throughthe Emergency Management
Port (EMP) for remote management, fan usage and processor cooling. Factory
authorized service personnel must unplug the AC cord before opening the chassis for
service.
The reset push button connects to the motherboard. If the SGI 1200 server freezes during
use, pressing the reset button issues a hardware reset to the BIOS, and the operating
system reloads.
Caution: Pressing the reset button is the last resort for dealing with a non-responsive
server. Any work not saved to disk will be lost when the reset button is pressed. Pressing
the reset button can leave the operating system in an uncertain state, so try logging into
an alternate console to cancel a runaway process before you reset your system. Check
with your system administrator.

4: Peripheral Use
You can remove the cover using the following information:
1. Grasp the plastic cover close to the right edge (where the door attaches to the
2. Pull outward and downward on the door and the cover detaches from the bracket.
To r ei ns ta ll th e do or :
1. Seat the lower ball in the hole in the bottom of the bracket.
2. Push the upper ball forward until it snaps into the hole on the top of the bracket.
Hot-swap Drive Use
If your SGI 1200 server has a RAID controller, it is essential to keep the following
warnings in mind as you begin using the hot-swap drives.
Caution: NEVER remove a hot-swap drive while the array is being rebuilt. The amber
global failure LED on the front panel blinks very slowly while the array rebuilds, so do
not remove a drive until the array is finished rebuilding. Never remove more than one
hard drive carrierfrom the SGI 1200 serverat a time. All RAID levels fail when more than
one hard drive is removed from the chassis. Also, do not operate your SGI 1200 for
extended periods without having all drive bays filled with either devices or a filler drive
blank.
bracket).
If your SGI 1200 server does not have a RAID controller, the hot- swap drives function
as removable drives only. Data is not protected if a hard drive crash occurs.
Use Figure 4-2 to correlate removable hard drives with their SCSI bay locations.

4: Peripheral Use
Remove a hard disk from the system using the following steps and Figure 4-3:
1. Grasp the middle of the release handle.
2. Squeeze the middle of the drive handle.
Note: If you are using an optional RAID controller, you must have the RAID
configured properly to remove and replace a hard drive carrier with the power on.
Refer to the PCI RAID card’s documentation for additional information.

3. Slide the hard drive out, see Figure 4-4.
Caution: If you do not have an optional PCI RAID card you will probably lose data on
a failed drive. You willneed to restorebackup data after the failed drive is replaced. Also,
allowing 30 seconds for the hard drive to spin down after releasing the drive handle is
highly recommended.

Hard Drive Upgrade Strategies
This section provides information about hard drive upgrade strategies for SGI 1200
servers with RAID and non-RAID drives. The SGI 1200 server can be configured with up
to four internal hard disk drives.
Note: When upgrading storage, the system must be powered down to install the new
drives, regardless of the drive type or RAID controller being used.
Caution: Always perform a full backup before upgrading your SGI 1200 server.
To install internal hard drives perform the following steps:
1. Back up your system.
2. Safely shut down the system.
3. Install the hard drive.
Hot-swap Drive Use
4. Restart the operating system.
5. Configure the new device as applicable to your operating system.
The two independent SCSI channels on the motherboard enable a variety of external
SCSI connections. Table 4-1 shows that the SGI 1200 server can be connected to Ultra
SCSI by way of an optional SCSI connector, and some versions can connect with an
Ultra2 connection.

Korean Class A Regulatory Notice
Shielded Cables
The SGI 1200-family of server systems is FCC-compliant under test conditions that
include the use of shielded cables between the server and its peripherals. Your server and
any peripherals you purchase from Silicon Graphics 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 Silicon Graphics, make sure they are shielded.
Telephone cables do not need to be shielded.
Optional monitor cables supplied with your server 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, a replacement cable
should be obtained from Silicon Graphics.
Electrostatic Discharge
Silicon Graphics 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 while you are operating the server system you keep all the covers and
doors, including the plastics, in place. The shielded cables that came with the server 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. The wrist strap is used when installing these upgrades to prevent the flow of
static electricity, and it should protect your system from ESD damage.
