About This Guide
This guide describes how to set up and operate a Silicon Graphics Origin200 server. It
contains the following chapters:
•Chapter 1, “Overview of the Origin200 System,”lists the main system features, and
describes its internal components, external connectors, and physical specifications.
•Chapter 2, “Setting Up an Origin200 System,”describes how to set up a
one-module or two-module Origin200 system. It shows how to open and close the
chassis, how to attach a system console, how to connect two Origin200 modules
together, how to turn on the system, how to log in for the first time, and how to turn
the system off.
•Chapter 3, “Installing an Origin200 System in a Rack,”describes how to install a
one-module or two-module Origin200 system in a rack cabinet.
•Chapter 4, “Operating an Origin200 System,”documents common tasks in
operating the server, including turning the system on and off, using the front panel
buttons (reset, nonmaskable interrupt), using the AUX port and the system
controller, and how to open the system chassis for servicing.
•Chapter 5, “Origin200 Cosmetic Features and Covers,”describes how to open the
various covers of the system, lock the chassis, remove and reattach the front door,
and adjust the system’s feet.
•Chapter 6, “Installing and Removing Memory,”describes how to install and remove
dual-inline memory modules (DIMMs) in an Origin200 module.
•Chapter 7, “Installing and Removing PCI Option Boards,”shows how to install
peripheral component interconnect (PCI) option boards in an Origin200 module.
