 Additional Procedures 5500—Software Installation Errors and L2 Cache Identification 

 

If the symptom occurs on a 5500 computer in the specified 

serial number range, inspect the logic board for “OPC” 

printed along the edge. If the logic board has “OPC” on it, 

verify the cache is a compatible L2 cache DIMM. If the logic 

board is an OPC with an incompatible L2 cache, replace the 

incompatible L2 cache with part number 661-1477.

 

Here is how to positively identify an OPC logic board:
1 With the logic board connector closest to you, examine 

the right and left edges of the board.

2 Along the right or left side you may see the letters OPC.
