About UltraSPARC III CPU Modules

The UltraSPARC III CPU module is a high-performance, highly integrated
superscalar processor implementing SPARC-V9 64-bit reduced instruction set
computer (RISC) architecture.

Note – There are now two types of UltraSPARC III CPU modules: the UltraSPARC

III 600, 750, or 900 MHz CPU module and the UltraSPARC III Cu CPU module.

Note – UltraSPARC III Cu CPU modules are marked “USIII Cu” (see FIGURE 1).

Note – Never mix UltraSPARC III 600, 750, or 900 MHz CPU modules with

UltraSPARC III Cu CPU modules. If the modules are mixed, the workstation will not
boot.

The workstation’s motherboard provides slots for two UltraSPARC III CPU modules.
Each processor module includes one CPU chip with an integrated memory cache for
data and instructions, as well as up to 8 Mbytes of external static random access
memory (SRAM) cache memory.

The CPU modules communicate with the workstation’s main memory and I/O
subsystem via the workstation’s high-speed data bus. The workstation CPU modules
are automatically synchronized with the system bus that runs at clock speeds up to
150 MHz.

Configuration Rules

The following configuration rules apply to UltraSPARC III CPU modules used in the
Sun Blade 1000 workstation:

■ You can install one or two UltraSPARC III CPU modules 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, you can. The speed of the modules does not need to be identical.

Finishing the Installation

1. If necessary, remove the antistatic wrist strap from the chassis.

2. If necessary, replace the access panel.

3. If necessary, install a lock block on the back panel of the workstation.

4. Reconnect any cables from external devices to the workstation.

5. Reconnect the workstation power cord.

6. Power on the workstation:
a. Turn on power to the monitor and to all external devices.
b. Press the power switch on the front panel and release it.
c. After several seconds, verify that the power-indicator LED on the power switch

is energized and listen to verify that the workstation fans are operating
(spinning).

7. The workstation should automatically recognize installation of the new CPU
module(s).

Note – Perform a reconfiguration boot ( boot -r ). If the workstation correctly

boots, the CPU module has been correctly installed.

If problems are encountered, verify proper POST operation. See Section 3.4
“Maximum and Minimum Levels of POST” in the Sun Blade 1000 Service Manual,
805-4495-10.
