4 Solving Problems
This chapter helps you identify and solve problems that might occur while you are using the system.
Resetting the System
To do this: | Press: |
|
|
Soft boot reset, which clears system memory and reloads the | <Ctrl+Alt+Del> |
operating system. |
|
|
|
Clear system memory, restart POST, and reload the operating | Reset button |
system. |
|
|
|
Cold boot reset. Turn the system power off and then on. This | Power off/on |
clears system memory, 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.
∙FRB 2 - 5 sec timer. If the primary processor does not come up in 5 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 off the primary processor.
∙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 off the secondary (if installed otherwise it will try to restart again off of the primary). Bad memory or a bad plug in card may cause an FRB 3 failure.
All failures are logged 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.
Initial System Startup
Problems that occur at initial system startup are usually caused by incorrect installation or configuration. Hardware failure is a less frequent cause.
