Checkpoint codes track the progress of POST routines at system startup or
reset. Checkpoint codes are shown on the checkpoint code display on the
EasyLED panel.
POST
When you turn on the server, it performs a series of tests to check the operation of
the server components and some optional devices in the server. This series of tests
is called the power-on self-test, or POST.
If a power-on password is set, you must type the password and press Enter, when
prompted, for POST to run.
If POST detects a problem, one or more beeps might sound, or an error message
is displayed. See “POST error codes” on page 143 for more information.
Error logs
The POST error log contains the three most recent error codes and messages that
were generated during POST. The IMM system event log contains messages that
were generated by the IMM. The system event log is a combined log that contains
messages that were generated during POST and all system status messages from
the service processor (IMM).
The system event log and IMM system event log are limited in size. When each log
is full, new entries will not overwrite existing entries; therefore, you must periodically
clear these logs through the UEFI Setup Utility program. When you are
troubleshooting an error, be sure to clear both the logs so that you can find current
errors more easily.
Important: After you complete a repair or correct an error, clear the IMM system
event log to turn off the system-error LED on the front of the server.
Entries that are written to the system event log during the early phase of POST
show an incorrect date and time as the default time stamp; however, the date and
time are corrected as POST continues.
Each system event log entry appears on its own page. To move from one entry to
the next, use the Up Arrow and Down Arrow keys.
You can view the contents of the POST error log, the system event log, and the
system event/error log from the UEFI Setup Utility program.
When you are troubleshooting PCI Express slots, note that the error logs report the
PCI Express buses numerically. The numerical assignments vary depending on the
configuration. You can check the assignments by running the UEFI Setup Utility
program.
Viewing error logs from the UEFI Setup Utility program
To view the error logs, complete the following steps:
1. Turn on the server.
2. When the prompt Press F1 for Setup appears, press F1. If you have set both a
power-on password and an administrator password, you must type the
administrator password to view the error logs.
3. Use one of the following procedures:
