About This Guide
Audience
This guide is written for owners, system administrators, and users of the SGI Origin 300
system with NUMAlink module. It is written with the assumption that the reader has a
general knowledge of computers and computer operations.
Your SGI system support engineer (SSE) should perform the addition or replacement of
parts and service of your SGI Origin 300 system, with the exception of the following tasks
that you may perform yourself:
• Installing your system.
• Connecting a system console to your Origin 300 base module.
• Connecting a Myrinet-2000 switch (clustered systems only).
• Using your system console to enter commands and perform system functions such
as powering on and powering off.
• Installing and removing disk drives.
• Installing and removing PCI option cards.
• Installing and removing DIMMs.
• Using the On/Off, reset, and non-maskable interrupt (NMI) buttons on the front
panel of an SGI Origin 300 base module.
