  • X4100 mysterious failure

    From jimbaez.auth@gmail.com@21:1/5 to All on Sun Apr 10 13:58:24 2016
    Necro on an old thread. Observation while repurposing two old X4100's.

    After loading them up with Debian, one started acting up with sporadic shutting down. Having a few of these chassis laying about, I first tried different PSUs. Then I switched to another chassis. No relief.

    I had replaced the coin batteries.

    Some research led me here. One thing became clear. These servers do not like noisy input power (understood from the UPS issues). So I checked. One power cord had slightly loose contacts on the IEC309 plug where it mates with the PSU, the other was fine.
    Still, I decided to replace this power cord.

    Problem solved.

    So I suspect that even the slightest noise on any PSU input can result in the mysterious power off. Note the other power cord was fine, but the other one not.

    If you run Linux on an X4100 you deserve hardware failures...

    From a hardware pov, if the power cord is loose in the socket,
    then you can expect arcing and surges at the power supply i/p,
    which could lead to psu failure. No machine is designed to
    suffer such abuse without at least some complaint...
