Reading the Message and Code Display
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 30-1 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 30-1 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.
