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
drive bays have no hot-swap data redundancy.

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:

Figure 2-5 shows the SCSI IDs that the midplane assigns. The midplane itself uses SCSI
ID 9.
Midplane is 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 the amber Global Failure LED that you can view through the front cover does light, you
can use the information in this section, and Chapter 5 to troubleshoot the failure source.

2: Hardware Overview
Warning: 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 through the 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.
Reset Push Button
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
bracket).
2. Pull outward and downward on the door and the cover detaches from the bracket.
To reinstall the door:
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 carrier from the SGI 1200 server at 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.
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.

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.
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.

two different methods to install new hard drives into a chassis with existing hard drives
already configured for RAID 5. The chassis must have a minimum of three hard drives
to support RAID 5. Both of these methods are summarized as B in Table 4-3. The first
method involves the following steps:
1.
Back up your system.
2. Safely shut down the system.
3. Install the hard drive.
4. Configure the new hard drive in a fault tolerant configuration in a second volume.
5. Start the system.
6. Configure the drive as a new logical volume.
The second alternative involves the following steps:
1.
Back up your system.
2. Safely shut down the system.
3. Install the hard drive.
4. Format hard drives to erase the old RAID 5 configuration.
5. Configure all the hard drives in the system as a RAID 5 as a single volume.
6. Start the system.
7. Restore your system files on the new drive configuration from backups.

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.
