ReadyNAS 3100: VBAT power is out of normal range

Hi all!

 

I have a ReadyNAS 3100 that started logging the following error:

VBAT power is out of normal range [expected: 3.30 current: 2.94].

 

Assuming the error was referring to the CMOS battery, I replaced the CR2032 lithium coin cell on the motherboard with a known good battery, and it's still complaining about the VBAT voltage.

 

Is there another 3.3-V battery somewhere that needs to be replaced?

 

Thanks in advance for any help!

  • That's odd, because I don't see any reference to VBAT in /etc/frontview/sensors/RN3100.conf.  Have you been independently doing something with lmsensors?

      Hi Sandshark,

       

      I inherited management of this device, and I assume it's bone stock. Having written that, is there a way to enable SSH so I can poke around and see what I have in /etc/frontview/sensors/RN3100.conf?

       

      Thanks for your help!

      On the Settings page, just click on SSH to enable it.  You then log in as user root using the NAS admin password.

       

      That said, boot_info.log does not contain that type of info on my various ReadyNAS, so I believe your predecessor has done some significant tweaking of the OS.  In order to do so, SSH would have to have been enabled.  So if the SSH button has a green bar on the Settings page, it's already enabled.

        User2032 - can you let us know what firmware you are running?

         

        Sandshark - it looks like it might be 4.2.x, which does have sensor data in boot_info.log.
