Poweredge R340. Amber light blinking

Hello

Yes, it could be related to the power outage. An amber light indicates that there was or is an error. It could be a current error or something that happened previously. An improper shutdown due to sudden power loss would likely cause several power related errors that may cause an amber light.

You should review the hardware log. You can access the hardware log from the iDRAC or management applications like OpenManage Server Administrator. You may need to clear the hardware log to clear the amber light.

Thanks

And, btw,

root" and "calvin".

is not working and from what I know, there is no default secure access which I should find it on the back of the server.

Thank you Daniel,

I'm connected through RDP. I've installed iDRAC Controller, and I access it through web (idrac.local)

It requests a username and password and for domain sais "This iDRAC". 

How can I create one?

Thank you,

If you don't know the iDRAC user/pass then you should be able to modify it through the host OS. There is no authentication required by default to make changes in the host OS. You may be able to modify user/pass through management applications like OpenManage Server Administrator or RACADM CLI commands.
