Action
A microprocessor test error has occurred.
Run tests 40, 48, 120, 121, and 122. If any of these tests fail, exchange
the FRU and run all the tests again to verify the repair.
Test 129 was run with a defective configuration tape. Attempt the
operation again with a configuration tape that is known to be good.
If this reference code continues to occur, exchange the FRU and
attempt the operation again to verify the repair.
There is no response across the interface. This reference will occur if
the interface card was exchanged and module U S 1 was not removed
from the old card and inserted into the new card. Ensure that module
U51 is correctly installed on the card.
If module US1 was correct, reseat the interface cable connectors and
the power cable connector on the interface card. Run test 45 (conti-
nuity test) to verify the repair.
If the reference code continues to occur, exchange the FRUs as
needed, and run test 45 after each FRU is exchanged to verify the
repair.
