Losing the System's Setup Conguration
1. Make sure that you are using a high quality power supply. A poor quality power supply
may cause the system to lose the CMOS setup information. Refer to Section 1.6 for
details on recommended power supplies.
2. The battery on your motherboard may be old. Check to verify that it still supplies
~3VDC. If it does not, replace it with a new one.
3. If the above steps do not x the setup conguration problem, contact your vendor for
repairs.
When the System Becomes Unstable
A. If the system becomes unstable during or after OS installation, check the following:
1. CPU/BIOS support: Make sure that your CPU is supported and that you have the latest
BIOS installed in your system.
2. Memory support: Make sure that the memory modules are supported by testing the
modules using memtest86 or a similar utility.
Note: Refer to the product page on our website at http://www.supermicro.com for
memory and CPU support and updates.
3. HDD support: Make sure that all hard disk drives (HDDs) work properly. Replace the
bad HDDs with good ones.
4. System cooling: Check the system cooling to make sure that all heatsink fans and CPU/
system fans, etc., work properly. Check the hardware monitoring settings in the IPMI
to make sure that the CPU and system temperatures are within the normal range. Also
check the front panel Overheat LED and make sure that it is not on.
5. Adequate power supply: Make sure that the power supply provides adequate power to
the system. Make sure that all power connectors are connected. Please refer to our
website for more information on the minimum power requirements.
6. Proper software support: Make sure that the correct drivers are used.
B. If the system becomes unstable before or during OS installation, check the following:
1. Source of installation: Make sure that the devices used for installation are working
properly, including boot devices such as CD.
2. Cable connection: Check to make sure that all cables are connected and working
properly.
