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.
