I have a HP DataVault X510 windows home server that does not appear to boot up anymore. It truns on displays all three lights (power, network & health) for a couple of seconds then turns of for a couple of seconds and tries to boot up again.

I have checked the network port by plugging it into my laptop and it works fine. I have also tried clicking the status/recovery button on the front to either get some status lights or boot the server into recovery mode but that has not had any effect.

Please find a short video of the bootup sequence here: http://youtu.be/djQ8-JFJkrg

How can i determine why it is not booting/how to fix it?

Looks like a hardware failure to me. What's the history of the server? Have you tried booting it with no drives installed?

Server hasn't been used in almost a year - it may have failed at some point then. I have tried booting it without the drives plugged in but it gives the exact same behaviour

Still sounds like a hardware failure to me. You can try the debug cable but I don't know if you want to spend money on that if it's indeed a failed server. viewtopic.php?f=6&t=8066

wow, very sorry to hear. Were you able to get it going? Did you send it for repairs? Will it be sold for parts?
God forbid you didn't throw it away!
Followup if you can.
