SCI SELF TEST Test (#231)
This is an on-board test which checks the basic functionality of the TN765 circuit
pack. This test runs in the background periodically, or it can be invoked via the
test interface PCS command. If this test continuously fails, then replace the
TN765 Processor Interface circuit pack. Refer to Chapter 6, ‘‘Reliability Systems:
A Maintenance Aid’’ for instructions on how to replace an SPE complex circuit
pack.
200 FAIL Checksum of Processor Interface failed.
1. Wait 1 minute and retry.
2. If the test continues to fail with a checksum failure, there could
be corruption on the tape. Replace the tape with a new tape
that contains Processor Interface firmware. Retry the
command. For G3i-386 and later, see note (b) of Hardware
Error Table for repair procedure.
3. In G3i-286 if the problem continues to exist after replacing the
tape, then replace the TN765 Processor Interface circuit pack.
Refer to Chapter 6, ‘‘Reliability Systems: A Maintenance Aid’’
for instructions about replacing an SPE complex circuit pack.
Retry the command.

FAIL Processor Interface Download failed. Refer to TABLE A Tape Unit
Aux Data Table and follow the repair recommendations.
1. Wait one minute and retry. See note (b) of Hardware Error
Table for repair procedure
2. If problem persists and TAPE is idle when command is
entered, then a problem may exist in either the TAPE or the
Processor Interface circuit pack. Replace the tape with a new
tape that contains Processor Interface firmware. Retry the
command.
PASS TN765 Processor Interface circuit pack initialized correctly.
Processor Interface links (BX.25 and ISDN) should recover now.
See PI-LINK for more information if links do not recover.
