Hi,I have a problem with Sun Fire x2250 (3 years old).In BIOS it shows hdds,usb,dvd,etc.But when I tried to boot nothing happen.Only the flickering comma.I tried reset bios,boot from usb or cd and it was same.Is there any idea for that?Sorry for my english (czech rep.).
I understand that you are able to access the BIOS. Try loading failsafe setting in BIOS and perform a cold powercycle.
From what is mentioned , It could be that the system is not able to get a boot device. Are the disks good. Is there a change if you remove the disks and CD drives ?.
Check the firmware and confirm that it is up to date.
Also if your ILOM is configured , try using the ILOM console redirection and check the Hardware logs to see if there are any errors.
Please check the MOS Doc - Sun[TM] x86/x64 Guide to System Troubleshooting [ID 1008335.1] and search for your platform.
For ILOM refer to http://www.oracle.com/technetwork/documentation/sys-mgmt-networking-190072.html
