2.4.2 POST progress codes (checkpoints)
When you turn on the blade server, the power-on self-test (POST) performs a series of tests
to check the operation of the blade server components. Use the management module to
view progress codes that offer information about the stages involved in powering on and
performing an initial program load (IPL).
Progress codes do not indicate an error, although in some cases, the blade server can
pause indefinitely (hang). Progress codes for blade servers are 9-word, 8-digit hexadecimal
numbers that start with C and D.
Checkpoints are generated by various components. The baseboard management controller
(BMC) service processor and the partitioning firmware are key contributors. The service
processor provides additional isolation procedure codes for troubleshooting.
A checkpoint might have an associated location code as part of the message. The location
code provides information that identifies the failing component when there is a hang
condition.
Notes • For checkpoints with no associated location code, see “ Light path diagnostics ” on
page 182 to identify the failing component when there is a hang condition.
•
For checkpoints with location codes, see “ Location codes ” on page 18 to identify the
failing component when there is a hang condition.
• For eight-digit codes not listed here, see
“
Checkout procedure
” on page 148
