ReadyNAS Ultra 2 (RNDU2205) does not boot

Hi,
After a sabettical some years, my ReadyNAS Ultra 2 (RNDU2205) wanted to serve me with it's storage.
After connecting the power, the fan starts blowing and that's all.
i've tried to get in the boot menu for a clean boot sequence by pressing the reset button for some seconds while booting, but no responses like mentioned in the support pages. The ReadyNAS doesn't respond to the powerbutton either. Only disconnecting the power helps.
Any suggestions what to do?

Regards
Han

    Have you looked with RAIDar to see the status?

    In addition, you can remove the disks (while powered down) and check them in a PC with the vendor tools. Seatools for seagate, Lifeguard for Western Digital.

    When did you purchase? The warranty is 3 years, so you might still be covered.
  • Hi Stephen,

    Tanks for your response, It doesn't get to a point of getting on the network, It's not detected. When i put the disks in my other ReadyNas, they are accessable. So i wonder, is there a battery or something on the mainboard (like on pc's) that can be dead?

    There might be a battery for the clock (there is on some models anyway). But a dead battery wouldn't prevent booting - I think all that happens is that the initial clock setting is wrong.

    Since the disks work in another unit, then the problem is not the related to them or the NAS configuration (since that is saved on the hard drives).

    That leaves the power supply and the system electronics. If your other NAS is also an ultra-2, you could try swapping the power bricks. If the front panel cooperates, perhaps also try a memory test.

    Contact support if you are within the 3 year warranty of course.
