Interpreting AP Error and Informational Messages

Unable to verify assertion of RESET SYS backplane signal (APERR 01)

This message, displayed during execution of the RS command, means that the backplane signal RESET_SYS- is not asserted when the AP attempts to reset the SPU.

This error might be caused by any one or a combination of four conditions.

Failure of the AP drive circuitry causes this error to be detected, and the SPU is not reset.

The circuitry that permits the AP to read this line may have failed. If this is the case, the error message is displayed, but the SPU is reset in the proper manner.

The CIO backplane may contain a short between the RESET_SYS- line and another low impedance line that is driving a high-logic level.

Some other device connected to the RESET_SYS- line may be driving a high-logic level that the AP cannot overdrive.

RESET_SYS backplane signal asserted, but unable to verify SPU deassertion of PPON backplane signal (APERR 02)

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.

PPON not reasserted by SPU after RESET_SYS deassertion (APERR 03)

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.

Unable to verify assertion of TOC_SYS backplane signal (APERR 04)

Information not currently available.

AP Self-Test failed subtest xx (APERR 05)

This message is displayed when a failure occurs during the execution of AP self-test. XX gives the decimal number of the failing subtest.

AP failed subtest xx of idle Self-Test. (APERR 06)

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.

AP failed subtest xx of prior idle Self-Test. (APERR 07)

This message is displayed when a switch in modes is made after idle self-test has failed previously.

Permitted accesses to NVM exceeded. (APERR 08)

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.

CRC error on NVM. (APERR 09)

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.

Illegal command, type HE for help. (APERR 10)

The first two characters entered in a command line for the AP command interpreter are not an AP command. Help displays all legal commands.

Expecting "Y" or "N" (APERR 11)

The AP is expecting one of the letters Y or N, in either uppercase or lowercase, as the reply to the query displayed on the screen.

Expecting "H" or "L" (APERR 12)

The AP is expecting one of the letters H or L, in either uppercase or lowercase, as the reply to the query displayed on the screen. H stands for high, and if chosen, causes the specified signal to be set to the high voltage level, which is nominally +9 Volts referenced to ground. L stands for low, and if chosen, causes the specified signal to be set to the low voltage level, which is nominally -9 volts referenced to ground.

Command may not be executed by a remote user. (APERR 13)

The command entered is a valid AP command, but is intended for use from the local console port (port T0) only. No action has been taken.

Your selection is outside of the legal range. (APERR 14)

Either numeric data has been entered when alphabetic input is expected (or vice versa), or the value of numeric data entered is outside of the permissible range of values.

Command may not be executed by a local user. (APERR 15)

This command is a valid AP command, but is intended for use from the remote support modem port (port T1) only. No action has been taken.

Expecting "S" or "M" (APERR 16)

The only permissible input at this time is the letter S for single or the letter M for multiple. They may be entered either in uppercase or lowercase.

Syntax error. (APERR 17)

Any error other than those covered by error messages APERR 18 and APERR 19 when using the DM, AM, DD, or AD commands, causes this error message.

Illegal hexadecimal entry. (APERR 18)

If any of the hex parameters entered with the DM, AM, DD, or AD commands are not valid hex numbers, this error message is be output.

Illegal address or address range. (APERR 19)

Attempting to address outside the legal range of addresses with the DM, AM, DD, or AD commands causes this error message to be given.

AP self-test passed. (APMSG 01)

AP self-test was executed, and it has passed. The message is accurate in almost all cases; however, it is possible that the message will appear without the test having executed to completion. This case can be detected by observing whether the full complement of subtests has been executed in the proper order.

AP self-test detects only approximately 70 percent of the faults on the AP.

SPU hardware was successfully reset. (APMSG 02)

This message indicates that the AP did not enter the three possible error states. It does not mean that the AP has somehow detected that the processor has restarted or that it was cleared, for example. The AP has no way to determine the internal state of any other assembly in the SPU.

Console terminal not set to 9600 bits per second. Console port will operate at xxxx bits per second. (APMSG 03)

The AP senses the setting of the console connected to local console port using ENQ/ACK. The console should be operating at 9600 bits per second. If it is operating at 4800, 2400, 1200, 600 or 300 bits per second, the AP senses this and operates the port at this baud rate.

If the above message appears on the terminal screen, the AP and the terminal are both set for the same baud rate. If the terminal is accidentally set for other than 9600, the above-referenced procedure should be followed to reset the terminal and AP for 9600. If the terminal is set for 9600, the AP or the terminal is defective.

String was truncated to 24 characters. (APMSG 04)

You can enter only up to 24 displayable characters in the answer to the query on the screen. All characters past the twenty-fourth were discarded. No action is necessary if the resulting truncated string is acceptable as the answer to the query. If the resulting string is not acceptable, continue command execution until you are again prompted for the string and enter the new string.

AP configuration lost. Use CA and ER commands to recover. (APMSG 05)

If this message recurs after each reset, power on, or self-test execution, the AP is defective.
