4.Turn on the server. If the problem remains, suspect the following components in the following order:
a.Power supply
b.
c.Memory
d.Microprocessor
e.System board
If the problem is solved when you remove an adapter from the server but the problem recurs when you reinstall the same adapter, suspect the adapter; if the problem recurs when you replace the adapter with a different one, suspect the system board or extender card.
If you suspect a networking problem and the server passes all the system tests, suspect a network cabling problem that is external to the server.
Problem determination tips
Because of the variety of hardware and software combinations that you can encounter, use the following information to assist you in problem determination. If possible, have this information available when you request assistance from Lenovo.
vMachine type and model
vMicroprocessor and hard disk drive upgrades
vFailure symptoms
–Does the server fail the diagnostic tests?
–What occurs? When? Where?
–Does the failure occur on a single server or on multiple servers?
–Is the failure repeatable?
–Has this configuration ever worked?
–What changes, if any, were made before the configuration failed?
–Is this the original reported failure?

You can solve some problems by comparing the configuration and software setups between working and nonworking servers. When you compare servers to each other for diagnostic purposes, consider them identical only if all the following factors are exactly the same in all the servers:
vMachine type and model
vLenovo ThinkServer Server Firmware level
vAdapters and attachments, in the same locations
vAddress jumpers, terminators, and cabling
vSoftware versions and levels
vDiagnostic program type and version level
vConfiguration option settings
