System Startup, Shutdown, and Conﬁguration

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 8-1. on page 268 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. on page 268 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.
