4. System cooling: Check system cooling to make sure that all system fans work
properly. Check Hardware Monitoring settings in BMC to make sure that the
SCM and system temperatures are within the normal range. Also check the
front panel Overheat LED, and make sure that the Overheat LED 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 minimum power require-
ment.
6. Proper software support: Make sure that the correct software and firmware
are used.
B. When the system becomes unstable before or during OS installation, check
the following:
1. Installation Devices: Make sure that the devices used for installation are work-
ing properly, including boot devices such as CD/DVD.
2. Cable connection: Check to make sure that all cables are connected and
working properly.
3. Using minimum configuration for troubleshooting: Remove all unnecessary
components (starting with add-on cards first) and use minimum configuration
(with a processor and two memory modules installed) to identify the trouble
areas. Refer to the steps listed in Section A above for proper troubleshooting
procedures.
4. Identifying bad components by isolating them: If necessary, remove a compo-
nent in question from the chassis, and test it in isolation to make sure that it
works properly. Replace a bad component with a good one.
5. Check and change one component at a time instead of changing several
items at the same time. This will help isolate and identify the problem.
6. To find out if a component is good, swap this component with a new one to
see if the system will work properly. If so, then the old component is bad.
You can also install the component in question in another system. If the new
system works, the component is good and the old system has problems.
C. When the system becomes unstable or you cannot boot to the OS
Please refer to Section B-2 in Appendix B for troubleshooting in an event when your
system becomes unstable or you cannot boot to the OS.
