1: Getting Started with the Silicon Graphics Prism
Optional SGI ImageSync Cabling
If your system was shipped from SGI with the modules already mounted in a rack and
the SGI ImageSync (IS) cables pre-installed, you should proceed to the next section,
“Connecting a Monitor” on page 18, and continue with the setup.
Note: When using an ImageSync card a monitor must be connected to the left channel
of the first pipe to which the ImageSync card is cabled.
If your system did not come with SGI ImageSync cables pre installed, use the following
steps to install them:
1. Connect the DB9 connector on the IS card in your base compute module to the SGI
ImageSync DB9 connector (labeled
IS1) located above the NUMAlink 1 connector on
the back of the XG2N using an SGI ImageSync DB9-to-DB9 cable.
2. Daisy-chain the SGI ImageSync cable from this first XG2N to any additional
graphics modules in your system by connecting an ImageSync DB9-to-DB9 cable
from the
Repeat connector (located above the NUMAlink 0 connector) and routing it
to the ImageSync connector (labeled
IS1) on the back of the next XG2N graphics
module, as shown in Figure 1-11.
Note: Figure 1-11 is intended only to show an example of how the ImageSync cables
connect. Your system may be configured differently.
Caution: Although the image sync subsystem uses DB9 connectors, these connectors,
whether on the ImageSync card or on the XG2N modules, are not serial ports.
Connecting a serial device to these connectors may cause damage to both the ImageSync
devices and the serial devices.
