System Diagnostics
Diagnostics (dgn) is the main troubleshooting tool. You can use it to check 
the hardware configuration, verify performance, and isolate failures to a 
field- replaceable unit (FRU). The Diagnostic tests are structured in such a 
way that the failing part is usually indicted by the first few test failures.
Some Diagnostic tests require that a Pin Verification Fixture (PVF, part 
number E9988- 67901) be installed on the testhead; other tests require that 
it not be installed. The Diagnostics program senses whether a fixture is 
installed or not and automatically runs the appropriate tests. 
Refer to Diagnostics in the Medalist i3070 online help for information on 
the Diagnostics software package, how to run it, what the tests are and 
how to use them for troubleshooting.
