Installing A Processor Module - Sun Microsystems Enterprise 10000 System Upgrade Instructions

Installing a Processor Module

1. If no processor modules exist on this board, install the modules in the following
order:
1. Processor 0
2. Processor 2
3. Processor 1
4. Processor 3
For increased processor performance, avoid populating processors 0 and 1 together
and processors 2 and 3 together.
2. Verify the new processor module speed is the same as all other processor modules
that are installed or to be installed in the system.
Mixing processors speeds in a system will cause the processors that do not match the
system clock speed to fail. Refer to sys_clock(1M).
3. Verify the new processor module cache size is the same as all other processor
modules that are installed or to be installed on the system board.
Mixing cache sizes on a system board will result in the larger caches sizes being
limited to the size of the smallest. If possible, move dissimilar processor modules to
another system board.
4. Remove the thin blue plastic strip from the processor board thermal pad on the
system board, if present.
This blue plastic strip covers a white thermal pad that provides thermal relief for the
cache on the processor module. When a processor module is installed, it should be
removed permanently.
5. Prior to installing the module, wipe the gold pads of the system board and the
exposed contacts of the compression connector with a lint-free non-abrasive cloth.
6. Align processor module compression connectors to the system board compression
mating backplate.
7. Engage all captive connector screws clockwise using a
#4-40 hex-head driver.
8. Tighten the captive connector screws to a low torque of 0.34 Nm (3.0 inch pounds)
in the pattern noted in .
