Check Point (CP) Codes

Codes beginning with “CP” are displayed on the LCD to indicate system status during POST. The CP codes vary with the level of microcode installed and the type of

processor card installed. The CP codes are not error codes. If the system detects an error, the CP code is changed to a POST error message.

System

Error

Log

 

 

 

 

 

 

 

 

 

The

computer

system maintains

a

system

error

log. The

BIOS

nonmaskable interrupt

(NMI) handler

writes

an entry

to the

error

log

each

time

the system detects

an error.

Viewing

the

error

log:

To view the error log, start the

 

system programs and selectMore utilities

from

the

Main

 

 

Menu,

then

selectDisplay

system

error

log.

For

any

 

 

 

error that is displayed, help

guide

you

through t

actions

to

take.

 

 

 

 

 

 

 

 

 

Error Storage:

 

The

error

log

stores

upuniqueto

three

 

errors (for example three parity errors at three differ

addresses). The multiple log counter (on the screen)

 

displays

the

number

of

times

each

unique error occurred.

You can page forward by pressing F8, or backward by

pressing

F7

to

view

the

stored error logs. The date

and

time

of

the most recent occurrence also is displayed. If

the

POST

finds

that

the

error log

has stored three

unique

errors,

the

POST displays179XXa

000error.

 

 

Note: If the system configuration is changed, the system clears any logged errors associated with the FRU that was changed. (For example, if the memory configuration was changed, memory errors are cleared from the error log). The conditions under which errors are cleared vary with the type of hardware and level of microcode installed.

Application:

If

the system diagnostics

run

error-free,

but you still suspect a problem, look

at the error log. If

errors

were detected, press the F1
