Problem Solving
This chapter helps you identify and solve problems that might occur while you are
setting up the system.
Resetting the System
To do This: Press:
Soft boot reset, which clears system emenory and reloads <Ctrl+Alt+Del>
the operating system.
Clear system memory, restart POST and reload the Reset button
operating system.
Cold boot reset. Turn the system power off and then on. Power Off/On
This clears system ememory, restarts POST, reloads the
operating system, and halts power to all peripherals.
Fault Resilient Booting
Fault resilient booting insures the system will not stop from a boot problem. Two
sets of timers are implemented in the BMC that will automatically reset the system
if the system should halt for some reason.
q FRB 2 - 5 second timer. If the primary processor does not come up in five
seconds the system will automatically reset and switch to the secondary
processor (if installed). If a second processor is not installed, the system
will try to restart the primary processor again.
q FRB 3 - 7 minute timer. If the system does not make it up to the end of
POST in 7 minutes, the system will automatically reset and try again. It is
assumed that the processor failed regardless of what may have caused the
system to hang. The primary processor is taken off line and the system will
boot from the secondary (if installed otherwise it will try to restart the
primary again). Bad memory or a bad plug in card may cause a FRB 3
failure.
All failures are recorded to the system event log.
The system will remember all FRB errors and display them at the end of POST until
you select the Processor Retest option from the BIOS Setup utility.
