Installing A Second Dcd - Silicon Graphics Octane2 Manual

2: Installing the DCD in a Dual Head Octane2

Installing a Second DCD

64
An Octane2 workstation with Dual Head V12 VPro graphics may be upgraded to contain
either one or two DCDs. The installation of the first DCD is described in the preceding
sections of this chapter. The installation of a second DCD is described in this section.
A Dual Head system with one DCD allows the connection of a total of three monitors:
two on the primary graphics head (the one toward the top of the system), and one on the
secondary graphics head (the one toward the bottom of the system).
A Dual Head system with two DCDs allows the connection of a total of four monitors:
two on the primary graphics head (the one toward the top of the system), and two on the
secondary graphics head (the one toward the bottom of the system).
To install a second DCD, follow these steps:
If you will install a second DCD at the same time as the first DCD, and thus have the Dual
Head XIO Module out of the Octane2 chassis and have the I/O panel removed, skip to
step 4.
1. Prepare the workstation as described in "Preparing Your Workstation" on page 36.
2. Remove the Dual Head XIO Module, as described in "Removing the Dual Head XIO
Module" on page 40.
3. Remove the I/O panel, as described in steps 1 through 11 (on page 44 through
page 51).
Before performing step 7 (on page 49), you will first need to remove the two screws
that hold a cover over the 13W3 connector. After performing step 7, you will then
also remove the four jackscrews on the first DCD.
In step 11 (on page 51), also remove the two rubber gaskets on DVI connectors, and
save them for later.
4. Turn the Dual Head XIO Module over, exposing the VPro graphics board on which
there is not yet a DCD installed.
5. Install the DCD as described in steps 13 through 17 (on page 52 through page 55).
6. Reinstall the I/O panel as described in steps 19 through 34 (on page 56 through
page 61).
Because at this point both VPro graphics boards have DCDs attached, it no longer
matters which board ends up at the top, as described in step 21 (on page 56).
