Isilon NL410 Node Backplane Light indicators (What do they mean?)

Hey Community,

Is there a doc that explains what the different light indicators mean on the backside of the Isilon NL410 nodes? Currently I have a flashing orange light on the back of one of my nodes and the rest have a solid green light.  I run isi_hw_status and I don't see anything glaring at me as a possible hardware issue.  Should I be looking for another command to show me what else could be wrong?

I have opened the installation guide for the NL410 and don't see anything in there telling me what the light indicators mean.

Thank you,

    Check this link:

    http://www.intel.com/content/dam/support/us/en/documents/motherboards/server/sb-s1400fp/sb/g64246003_s1400fp_tps_r2_0.pdf

    Section 10 / Intel Light Guided Diagnostics

    However it might not reveal much...  See if you have any hardware events in the SEL (System Event Log), to list all SEL entries:

    /usr/bin/isi_hwtools/isi_ipmicmc -S -V -p l

    l is lowercase 'L'.

    I had one such incident and it turned out to be the CMOS battery that had to be changed on the motherboard.

    In the output of 'isi_hw_status' it was the 'BB VBAT' sensor that was low, but we also got this cluster alert that pointed us in the right direction:

    Message: BB VBAT has exceeded Lower Critical threshold: 0.995 (threshold: 2.211)

    Yan Faubert,

    Hey thank you for this info.  I went ahead and reset the node to and started it back to the setup menu and the orange light went away.  I am not saying this is the fix, but if that light start flashing again I will be sure to take a closer look at what you have here.  Thank you for the quick response!
