Class Error 9: Console Path Test

Class Error 9

Console path related errors and/or channel I/O errors take the following multiplexed code form:

01wx
9yzz

where:

w = CIO slot number (<> C)
x = Device address (always 0 for the console)
y = CIO mid-bus slot number
zz = IODC driver error code 00 - 7F.

0100 9y80

MESSAGE: None.(I)
CAUSE: I/O dependent code (IODC) from channel I/O bus (CIO) in console path fails.
ACTION: None. If problem recurs or is suspected cause of a future system problem or failure, contact your Hewlett Packard Support Representative.

MESSAGE: No message. Self-test continues. (W)
CAUSE: Access port self-test fails. "zz" = AP self-test code (00-7F).
ACTION: If AP not functional, reset the system from the front panel. If a soft reset/transfer of control is needed, set switch 3 on the system monitor card to the open position and reset the system from the front panel. If AP is functional and can reset the system, note the error as a possible console path or CIO bus problem should a future problem or system failure occur.

01C0 9yF0

MESSAGE: No message. Self-test continues. (W)
CAUSE: Access port read of the hexadecimal display fails.
ACTION: None. Note error should a future system problem occur.

01C0 9yFF
