Chapter 7: Troubleshooting and Support
•
Check for bad DIMM modules or slots by swapping modules between slots and noting the
results.
Losing the System Setup Configuration
•
Use a high quality power supply. A poor quality power supply may cause the system to
lose the CMOS setup information.
•
Check that the motherboard battery still supplies ~3VDC. If it does not, replace it.
If the above steps do not fix the setup configuration problem, contact your vendor for repairs.
When the System Becomes Unstable
If the system becomes unstable during or after OS installation, check the following:
•
CPU/BIOS support: Make sure that your CPU is supported and that you have the latest
BIOS installed in your system.
•
Memory: Make sure that the memory modules are supported. Refer to the product page on
our website at
www.supermicro.com
. Test the modules using
memtest86
or a similar utility.
•
Storage drives: Make sure that all drives work properly. Replace if necessary.
•
System cooling: Check that all heatsink fans and system fans work properly. Check
the hardware monitoring settings in the BMC to make sure that the CPU and system
temperatures are within the normal range. Also check the Control panel Overheat LED.
•
Adequate power supply: Make sure that the power supply provides adequate power to
the system. Make sure that all power connectors are connected. Refer to the Supermicro
website for the minimum power requirements.
•
Proper software support: Make sure that the correct drivers are used.
If the system becomes unstable before or during OS installation, check the following:
•
Source of installation: Make sure that the devices used for installation are working properly,
including boot devices.
•
Cable connection: Check to make sure that all cables are connected and working properly.
•
Use the minimum configuration for troubleshooting: Remove all unnecessary components
(starting with add-on cards first), and use the minimum configuration (but with a CPU and
a memory module installed) to identify the trouble areas.
•
Identify a bad component by isolating it. Check and change one component at a time.
