General Rules for System Configuration E-5
E
If a color monitor is used, a color-graphics interface card must be installed in
SBus slot 1. Only one color-graphics interface is allowed in the system.
E.3 System Slave Boards
The remaining system boards are “slave boards,” because the master board
exercises control during portions of boot and other system operations.
For uniformity of configuration and ease of service, install and equip slave
system boards according to the guidelines below. (These guidelines are not
required by system architecture, but are strongly recommended, to maintain
consistency between systems and to simplify service procedures.)
1. Install slave boards in the lowest card cage slot numbers, following the
system master.
2. Installing SuperSPARC modules strictly according to the guidelines
presented in Section E.3.1.
3. Install SIMM devices strictly according to the guidelines presented in
Section E.3.3.
E.3.1 SuperSPARC Modules
When installing or replacing a SuperSPARC module, use the following
guidelines to verify that you have selected a valid location.
Warning – The heatsinks on the SuperSPARC module may be hot. Use caution
when removing or installing SuperSPARC modules and avoid contact with the
heatsinks. Hold SuperSPARC modules only by the edges.
Each system board has two SuperSPARC module connectors, designated A and
B (location A is closest to the backplane connector). See Figure E-2. Modules
mount above the system board on standoffs. Modules should first be installed
