Three types of messages (informational/run time, error, and warning) may occur
during the reset, startup, or shutdown process.
Informational messages indicate which component the self-test is
testing at any given time.
Error messages indicate a hardware failure or operating system
error. Class errors are grouped into 14 classes ( 1-CE). They are
hexidecimal messages that appear on the front panel LED display and
access port status line. All other errors are considered non-class,
and can appear on the panel or on the system console itself.
If a class error is encountered (see
Table 8-1 "Class Error Descriptions"
for the types of classes), the self-test halts and error messages are
displayed.
Warning messages identify noncritical failures that do not prevent
the system from booting or halt the self-test.
Information messages, error codes, and warnings are displayed (in hexadecimal)
on the front panel LEDs, the access port status line during bootup, and the
system console. English language messages can also appear in addition to or in
place of a hexadecimal message at the console.
NOTE: Some console messages are also logged to the system log file.
Interpreting Class Errors
Fifteen classes of codes comprise the informational, error, and warning
messages. The class number is the leftmost hexadecimal value for the singular
display and for the second multiplexed (alternating) display.
Table 8-1 "Class Error Descriptions" lists
the class error number, its hexadecimal code, and the cause of the error. To
determine an error's class, check its numeric code in the table. Then locate
the subsection in this chapter which addresses that class.

Categories of "nonclass" errors appear on the following page.
Interpreting "Nonclass" Errors
Besides class errors, the system console also displays the following types of
errors:
Run-time codes
DCC error
High priority machine check (HPMC) detailed errors (XXF0-XXFF)
Log file errors
SYSGEN messages (I/O, MISC, LOG, SYSFILE)
Outerblock messages
SERVE messages
Other messages
Scanner messages
Boot tape messages
LANGINST messages
* Multiprocessor errors
These error messages appear after the class errors in this
chapter, in the same order shown in the list above. If unlisted
errors occur, call your Hewlett-Packard support representative.
