3.4.3 UltraSPARC Modules
Each CPU/Memory board has four connectors for UltraSPARC modules (up to
two modules per board, two connectors per module). For each module, there is
a connector with 144 pins and a connector with 288 pins. See Figure 3-9.
3.4.4 Handling Precautions
The following precautions should be exercised when handling UltraSPARC
modules:
•
UltraSPARC modules are static-sensitive and a grounding wrist strap field
kit must be used when handling the modules.
•
Always handle the modules by the edges and not by the smaller black heat
sinks that break easily if handled improperly.
•
Do not handle the modules by touching the gold pins on the compression
connectors. Natural oils on the hands cause these connectors to oxidize and
corrode over a period of time, resulting in the need for module cleaning or
replacement.
