Minor (I hope!) Crisis - E450 will not power up
UNIX Friends,
Came in this morning to a downed E450 - thought it had been a power disaster. But wasn't! Machine had apparently shut itself down.
All three power supplies are double-green, and case interlock switch is closed...
As this is the first time we've had such a catastrophic(?) failure, am now taking the approach of removing components (with a bit of vacuum cleaning), and replacing one by one to see if one is defective. With CPUs, DC modules and memory removed, no combination of key position, power switch, etc. gets us back to the boot prompt. Having never tried this before, is this expected behavior?
Qs:
Is this diagnostic approach reasonable?
Will the machine get through its POST, and to a boot prompt, with no CPUs, no DC power modules, or memory?
If not, what is the minimum component content for the machine to power up?
Are there Best Practices Strategies for performing these (failed component) diagnostics?
Yes, with the machine up, in the past, a check of the log would reveal drive problems, overheating problems, etc.
But, with no Boot Prompt available, what's a lowly SysAdmin to do?
Many thanks for your wisdom and insights.
