Configuration Rules; Cpu Module Slot Positions In The Workstation - Sun Microsystems Sun Blade 1000 Service Manual

8.1.2

Configuration Rules

The following configuration rules apply to both UltraSPARC III CPU modules and
UltraSPARC III Cu CPU modules used in the Sun Blade 1000 and Sun Blade 2000
workstations:
You can install one or two UltraSPARC III CPU module(s) into the workstation
motherboard.
Always insert the first CPU module into CPU processor slot 0 (connectors J0501
and J0601).
If a second CPU module is to be installed, install the second CPU module into
CPU processor slot 1 (connectors J0701 and J0801).
If you wish to install more than one UltraSPARC III 600, 750, or 900 MHz CPU
module into a Sun Blade 1000 workstation, you can. The speed of the modules
does not need to be identical.
If you wish to install more than one UltraSPARC III Cu CPU module into a Sun
Blade 2000 workstation you can. However, the speed of the modules must be
identical.
Note – Never mix an UltraSPARC III 600, 750, or 900 MHz CPU module with an
UltraSPARC III Cu CPU module. If the two types of modules are mixed, the
workstation will not boot.

CPU Module Slot Positions in the Workstation

Caution – CPU slot positions 0 and 1 are shown in
is the required position for all workstations that contain only one CPU.
The CPU modules are enclosed in a cooling shroud and secured to the shroud with
captive screws that must be torqued to specific values.
