System Startup, Configuration, and Shutdown Reference Manual (32650-90907)

Appendix A
Using the Access Port (AP)
Configuring the Console
181
If the AP command interpreter encounters errors or inappropriate input during the reset (RS) process, it may
display a combination of the following messages:
Expecting ”Y” or ”N” (APERR 11)
Unable to verify assertion of RESET_SYS backplane
signal (APERR 01).
RESET SYS backplane signal asserted, but unable to
verify SPU deassertion of PPON backplane
signal (APERR 02).
PPON not reasserted by SPU after RESET_SYS
deassertion (APERR 03).
The last three messages appear as a result of certain failures detected by the AP during the reset process.
These messages are key to isolating the cause of the failure of the failed field-replaceable unit.
Once the reset is complete, the system displays the following message:
SPU hardware was successfully reset. (APMSG 02)
Transferring Control (Soft Reset)
The TC command initiates a transfer of control, or soft reset, of the system.
Should an error be encountered during a TC, the system displays following error message:
Unable to verify assertion of TOC_SYS backplane signal
(APERR 04).
Testing the AP
Entering TA executes the AP self-test. The system displays a message during self-test:
CM>TA Return
Console data arriving during self-test execution
will be lost.
Type Y to confirm your intention to execute AP Self-Test (Y/N): Y
Starting AP Self-Test. Last subtest will be 30.
Executing test number:
00 01 02 03 04 05 06 07 08 09
10 11 12 13 14 15 16 17 18 19
20 21 22 23 24 25 26 27 28 29
30
AP Self-Test passed. (APMSG 01)
If the self-test fails:
AP Self-Test failed subtest xx (APERR 05).
where xx is the number of the test causing the failure. If the self-test hangs, the last number displayed is the
failing subtest, provided that the numbers have appeared in numerical order (which is the expected
sequence).
