5.4 SUBASSEMBLY TROUBLESHOOTING
Once you have positively identified a problem with the UC5E, it will be necessary to
troubleshoot the problem to the assembly level, and replace the faulty assembly.
5.4.1IDENTIFYING THE FAULTY ASSEMBLY
A problem or fault must be traced to one of the subassemblies of the UC5E. As a
general rule, it is best to check the subassemblies in order according to their
respective expected failure rates, keeping in mind the failure symptoms. Therefore it
is generally recommended that the boards be checked in the following order:
1) The 16MB SIMM
2) The Main Board itself
IMPORTANT: The procedures to identify in which component the problem lies may
be used to verify the operation of the indicated subassembly. If operation of any
particular subassembly cannot be verified, replace the entire subassembly – do not
attempt component-level repair.
