System Startup, Configuration, and Shutdown Reference Manual (32650-90892)

194 AppendixA
Using the Access Port (AP)
Configuring the Console
CAUSE: This message, generated during execution of the RS command, indicates that the
PPON backplane signal is not deasserted within 2 seconds after the RESET_SYS- line is
asserted.
This error may be caused by three conditions. If the receiver, which senses this state of this
line on the AP, has failed, the system displays the message. The SPU resets normally. The
AP also resets itself as soon as the RS command has completed, if this is the cause of the
failure.
If the wiring between the assembly that receives RESET_SYS- and the AP is defective,
neither the SPU nor AP resets.
If the portion of the power system that generates PPON is defective, the SPU does not
reset, and the AP probably does not reset.
MESSAGE: PPON not reasserted by SPU after RESET_SYS deassertion (APERR 03)
CAUSE: This message, displayed by the RS command, means that PPON has not reasserted
within 2 seconds after being deasserted. Once this occurs, the AP becomes insensitive to
being reset by the deassertion of PPON.
This error is most likely the result of a fault in the assembly that generates the PPON
signal.
MESSAGE: Unable to verify assertion of TOC_SYS backplane signal (APERR 04)
CAUSE: Information not currently available.
MESSAGE: AP Self-Test failed subtest xx (APERR 05)
CAUSE: This message is displayed when a failure occurs during the execution of AP
self-test. XX gives the decimal number of the failing subtest.
MESSAGE: AP failed subtest xx of idle Self-Test. (APERR 06)
CAUSE: This message is displayed when the idle self-test fails.
Since idle self-test executes whenever the AP microprocessor has idle time, this message
may appear at any time, in any AP context, including during console mode operation.
MESSAGE: AP failed subtest xx of prior idle Self-Test. (APERR 07)
CAUSE: This message is displayed when a switch in modes is made after idle self-test has
failed previously.
MESSAGE: Permitted accesses to NVM exceeded. (APERR 08)
CAUSE: This message is displayed each time that the AP accesses NVM after the counter
in NVM indicates that the permitted number of accesses to the last block of NVM has been
exhausted. The AP should be replaced at the next visit by HP service personnel. The NVM
may survive for up to 20,000 more accesses after this message begins to occur, or it may
fail almost immediately.
MESSAGE: CRC error on NVM. (APERR 09)
CAUSE: This message is displayed when the AP has exhausted the permitted number of
accesses to all blocks of NVM. The default settings for NVM parameters are used. Notify
your HP service personnel. The AP must be replaced.
MESSAGE: Illegal command, type HE for help. (APERR 10)
