Duplication Interface Circuit Pack SPE A Loop
Back Test (#275)
This test loops data back through the UART used to communicate with
Maintenance/Tape Processor A. The data is generated by the Duplication
Interface circuit pack processor and is looped through the UART. The test is done
entirely on the Duplication Interface circuit pack. The test passes if the data sent
matches the data received. This test does not check the physical serial channel
that is printed on the backplane or carried by the ICC.

Result Description/Recommendation
1000 ABORT System resources required to run this test are not available.
2000 ABORT Response to the test request was not received within the
allowable time period.
2033 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5
times.
FAIL The tested UART on the Duplication Interface circuit pack is
defective.
1. If this is Duplication Interface circuit pack A, then the
circuit pack must be replaced to restore duplication. If this
is Duplication Interface circuit pack B, then this failure has
no real impact on the system. However, since this
Duplication Interface circuit pack can never be used in the
A carrier, it should be replaced at some point.
2. Follow general procedures for replacing Common Control
circuit packs, and replace the Duplication Interface circuit
pack.
3. Rerun the test.
NO
BOARD
The Duplication Interface circuit pack has failed to handshake
with either the active Maintenance/Tape Processor (in the
case of Duplication Interface circuit pack A) or the Duplication
Interface circuit pack A (in the case of Duplication Interface
circuit pack B).
1. Refer to NO BOARD description for the Duplication
Interface Circuit Pack Status Query Test (#315).
PASS The SPE A UART on the Duplication Interface circuit pack is
good. This implies that Duplication Interface circuit pack A
should be able to communicate with SPE A. This implies that
Duplication Interface circuit pack B has a good UART.
