About This Guide
This guide provides you with information on using and administering your SGI 1200
server. Although there are a number of models in the SGI 1200-family of servers, this
document refers to the products generically as SGI 1200 servers. The following section
describesthisproduct’sfeatures.
Product Features
The SGI 1200 server has one or two processors, and the chassis is built in a 2U form factor.
Some of the server’s features include:
• 2U (3.48-inch) height for convenient placement in a 19-inch EIA rack
• One or two Intel Pentium III processors
• Ultra2 SCSI controller, S-VGA video, serial, parallel ports and 10/100-BaseT
Ethernet on the motherboard
•Upto2GBofECCSDRAM
The SGI 1200 has four hard disk bays and an SCA (Single Connector Attachment)
midplane for easy drive removal, replacement and chassis monitoring. The server can
support hot-swap drives with an optional SGI 1200 server RAID controller. Other
features include:
• Remote Server Management Port
• 400 watt autoranging power supply
The following topics are covered in this manual:
• Chapter 1, “Site Preparation and Technical Specifications” provides environmental
and technical infomation needed to properly set up and configure the SGI 1200
server system.

007-4248-001 xii
• Chapter 2, “Hardware Overview” lists information on the server’s chassis,
connectors, motherboard, LEDs, drives and other hardware components.
• Chapter 3, “Mounting the Server in a Rack” gives information on the proper
procedures for mounting the SGI 1200 server system into a rack. Basic power and
I/O connections for starting the system are covered.
• Chapter 4, “Peripheral Use” describes how to access, use, and replace the server’s
peripheral components.
• Appendix A, “Regulatory Specifications” lists all regulatory information related to
the use of the server in the United States and other countries.

Conventions and Terminology
This guide uses the following conventions:
• References to document titles are in italics.
• Commands and names of files appear in text as italics.
• References to other chapters and sections within this guide are in quotation marks.
• Anything that you type on your keyboard is in Courier bold.
• Anything displayed on the screen is in Courier.
• Steps to perform tasks are in numbered sentences. When a numbered step needs
more explanation, the explanation follows the step and is preceded by a square
bullet.
• Warning text that describes conditions that could cause injury or death is
highlighted with a lightening bolt icon in the left margin.
Figure ii Injury or Death Warning Icon
• Warning or caution text that describes conditions that could cause equipment
damage or major data loss is highlighted with a explanation mark in the left margin.
Figure iii Equipment Damage or Data Loss Warning Icon
In addition, the term “hot-swap” in text with a RAID controller indicates that a hard
drive can be removed and replaced while the server is running without data loss in a
RAID configuration. Otherwise, the term “hot-swap” indicates that hard drives are
conveniently removed and replaced for service and drive expansion, however no data
redundancy occurs.

1: Site Preparation and Technical Specifications
As shown in Figure 1-1, the airflow in the server chassis flows through the mesh grill at
the front of the chassis through the power supply, and over the motherboard. The hot air
exhausts out the back of the chassis.
Caution: Always keep at least 2 inches (5.1 cm) of clearance at the back of the chassis for
cooling.

2. Hardware Overview
This chapter provides information about the SGI 1200 server’s hardware. In the first
section, information about the motherboard is presented, and in the following sections,
the text and supporting illustrations provide information about chassis internals,
connectors and LEDs.
Theory of Operations
The SGI 1200 server uses an Intel motherboard with the following features:
• MP (Multi-Processor) ready processor host bus interface support
• Dual or single Intel Pentium III processors
• Support for up to 2 GB of ECC memory
• Supports the ACPI (Advanced Configuration and Power Interface) power
management specification
• L2 cache configurations of 512 KB
• Embedded dual function SCSI controller provides both Ultra2 (LVDS) wide and
UltrawideSCSIinterfacesastwoindependentPCIbusmasters
• Fast IDE controller support for removable media drives
• 10/100 Base-T ethernet support at burst rates of up to 132 MB/sec from the PCI bus
to the ethernet controller
When you first boot your system you will see an Intel mother board identification
number listed (for example L440GX+). If you need specific technical information
regarding your server’s mother board you can access the Intel documentation directly at:
http://support.intel.com/support/motherboards/server/

6007-4248-001
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.
