1850 wont start -- need help troubleshooting issue.

[Michael Herman_1]

My proliant 1850 died yesterday and I'm not sure what the issue is. When I turn it on, the motherboard lights up for a second...the fans start going....then it shuts off. Two LEDs on the motherboard flash RED.. they are CR511 and CR522.

Anyone have any clues? Thanks in advance.

Michael:

While the server is open (i.e., top cover off) power on the server and make sure all the fans spin up. You may have a redundant fan or primary fan that has failed. Alternatively, one of the power supplies may have failed.

Thanks John...Actually..all the fans power up..for that one second... and the power supply fan starts as soon as I plug it in and stays running. I thought it might be the power supply but I'd rather be sure before I spend the money.

Is there a schematic somewhere that would shed some "light" on those LEDs??

Unfortuantely, I could not find one in the documentation. Sorry.

Hi,

CR511 and CR522.

I've attached the marked-up board jpg for your review. Those are the general areas where the lights flash red.. Thanks

what happened to the jpgs that were attached to this thread?? I get "page can not be found" on both now.

Anyhow. one more thing. on the board near the CR522 LED are the words "ERR PWR". Which indicates a power error but i've switched out the power suppy and the same thing still happens.

I called HP support and they want to charge me $75 to "attempt" to figure out what is wrong. I'm not asking them to buy the parts for me....I just want to know how their system errors out. Those flashing LEDs are there for a reason....Just tell me what needs to be replaced...geez.

Can Anyone shed some light? Thanks.
