Page 40: Memory
Chapter 1: Overview of the Origin200 System Memory Each Origin200 module can have between 32 MB and 2 GB of memory, depending upon the type of dual in-line memory module (DIMM) that you install. DIMMs are installed in sockets that are grouped into two banks of four sockets each. Figure 1-7 shows the layout of the DIMM sockets on the main system board.
Page 41: Internal Drive Options And Scsi Channels
Maximum interleaving is achieved with a single bank. Internal Drive Options and SCSI Channels The Origin200 server provides bays for two sizes of internal drive options: 5.25-inch drives and 3.5-inch drives. 5.25-Inch Drives and Drive Bay The 5.25-inch drive bay can be used for two combinations of drive form-factor:...

Page 46: Ethernet Port
Category 5 wiring is required for proper 100-Base-TX operation. External Interrupt Ports The Origin200 server has two connectors for use with the external interrupt interface. This interface allows separate systems to send and receive interrupts over a dedicated wire for purposes of inter-system synchronization. Using this device, a user process may generate outgoing interrupts to other systems, or receive interrupts from other machines in a variety of ways.
Page 47: Power Supply
When using an uninterruptable power supply (UPS) with an Origin200 server, be sure that the UPS can supply up to 140 A of inrush current. Each Origin200 module can draw up to 140 A of current brieﬂy when you power it on, even though the sustained current drawn is only a fraction of that.
Page 48: Air Flow And Fans
Chapter 1: Overview of the Origin200 System Air Flow and Fans Air ﬂows through the Origin200 from the front of the system to the rear, and is drawn by three DC fans located just behind the internal drive bays. The maximum ﬂow rate is 100 cfm (0.047 m...

The rackmounting shelf does not isolate the server from mechanical shock and Note: vibration. If you plan to use a rackmount Origin200 server in an environment that will subject the system to excess vibration, you should obtain a mounting system capable of dampening the vibration.
Page 59: Providing Space Around The System
Be sure to provide adequate space for proper airﬂow and cooling. Refer to Table 1-7 in Chapter 1, “Overview of the Origin200 System” for a complete list of environmental speciﬁcations. Also, see “Air Flow and Fans” on page 22 for a description of the air ﬂow through the Origin200 server.

Page 115: Using Another Computer Or Workstation As The System Console
(such as Term, HyperTerm, TERMINAL.EXE, Bitcom, ProComm, ZTerm, SITcomm, or Macterm) The basic steps to using a computer as a system console for your Origin200 server are: • Connect a serial port of the computer to serial port 1 of the Origin200 server.
Page 116: Figure 4-6 Attaching A Serial Cable To Port 1 Of The Origin200 Server
Origin200 server: 1. Make sure the Origin200 server is turned off. 2. Locate the serial cable that was shipped with your Origin200 server. 3. Attach the DB9 connector to serial port 1, as shown in Figure 4-6.
Page 117: Setting Up And Starting The Terminal Emulator
Setting Up and Starting the Terminal Emulator To communicate with the Origin200 server, you need a terminal emulator for your IBM compatible or Macintosh computer. Many operating systems, such as Microsoft® Windows®, ship with a terminal emulator package (also known as modem or communications software.) Some examples of terminal emulator software are:...
Page 118: Table 4-2 Terminal Emulator Settings
Note which terminal type (such as VT100 or ANSI) you choose to emulate. You will need this information when you log in to the Origin200 server. Other settings, such as upload and download protocol, initialization strings, and ﬁle transfer settings do not matter for this procedure.
Page 119: Logging In To The Server
, make sure the cables are correctly attached. The DB9 connector Enter on the long serial cable (shipped with the Origin200 server) must be in port 1 of the server. Make sure you have conﬁgured the terminal emulator to use the correct serial port on your computer.

Page 133: Determining The Devices Installed On Your Server
Reports the MSC ﬁrmware revision number. Determining the Devices Installed on Your Server Because the Origin200 server, like the rest of the Origin product line, is a highly conﬁgurable multimodule system, there are some differences in the way that devices are identiﬁed and conﬁgured from prior Silicon Graphics workstations and servers.
Page 134: How Devices Are Detected And Numbered
See ioconﬁg(1M) for more information. How to Use the Hardware Graph The hardware graph is a tool for inventorying the I/O devices on all Silicon Graphics Origin and Onyx2 systems. Unlike hinv, the hardware graph is an IRIX ﬁlesystem, whose branching character accommodates the possibility of multiple nodes, each with multiple I/O devices of several types.
Page 135 Determining the Devices Installed on Your Server To see the hardware graph, use the ls command. For example: # ls /hw console input2 mmem scsi zero cpunum kmem module scsi_ctlr disk machdep nodenum tape external_int null ttys input midi rdisk unknown The contents of the directories can be either IRIX special device ﬁles or subdirectories.
Page 136: Figure 4-8 Example /Hw Filesystem
Chapter 4: Operating an Origin200 System To determine the number of nodes present in the system, enter # ls /hw/module This indicates two nodes. Modules and slots are numbered with base 1; PCI slots are numbered with base 0. Nodes are numbered 1 and 2.

Page 209: Attaching Serial Cables
Attaching Serial (ASCII) Terminals You can connect an optional ASCII terminal to your Origin200 by using the serial cable shipped with your server. It has a DB9 connector on one end and a 25-pin serial connector on the other. See Appendix B, “Cable Descriptions” for information on this cable.
Page 210 Chapter 8: Installing and Configuring Peripherals In some cases the terminal may need special recognition from the system software. You can check or set up the system software to work under speciﬁc parameters by following these steps: 1. Log in to the system as root. 2.
