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.
