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, 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:
1. For checkpoints with no associated location code, see “Light path diagnostics” on page 214 to identify
the failing component when there is a hang condition.
2. For checkpoints with location codes, see “Location codes” on page 14 to identify the failing
component when there is a hang condition.
3. For eight-digit codes not listed here, see “Checkout procedure” on page 184 for information.
The management module can display the most recent 32 SRCs and time stamps. Manually refresh the list
to update it.
Select Blade Service Data > blade_name in the management module to see a list of the 32 most recent
SRCs.
