    Default Remotely *reseting* PC via X10?

    Hi,

    I run a web server at home and am concerned about hard lock-ups whilst I am away. I essentially want a robot to go and press the reset button in the event of a hard lockup! However, back to what can realistically be accomplished:

    My planned solution to this involves X10. Please let me know what you think or whether there is a better solution.

    1) I was planning on plugging the server's power lead into an X10 Appliance Switch.
    2) I would have an old networked 486 running Linux with a CM12U connected.
    3) If I needed to reset the server, I would ssh into the 486 and tell the X10 power unit attached to the server to power-off, then power-on again.
    4) The BIOS on the server is set to power-on if power has been cut & restored.

    It's a little frustrating in that all I need to do is short a pair of pins on the motherboard to reset the server - something that could be done with a 486, an RS232 and a switch, if I had the electronics knowledge!

    Any thoughts?

    Cheers,

    Hi Rich,

    Instead of an appliance module on the power lead you could use one of these units wired across the reset pins:

    If you couple that with one of these:

    You don't even need to keep a PC on - you can dial into the alarm panel and instruct the X10 modules on/off

    HTH,

    Tim.

    TimH has beaten me to it. But his approach is probably the best. Something else to think about especially if the Bios has been to set to power-on if power has been cut & restored. I would recommend a time delay so when the power comes on there is a 30 minute delay before the power to the pc is switched on. You can get delayed on relays from RS http://uk.rs-online.com/web/search/s...duct&R=0214640 This is to stop the odd power fluctuations you sometimes get when power is restored affecting the pc during boot up. As it may go off again within a few seconds of being on.
    If you want to go with TimH's suggestion then we have a few SC28X we want to get get rid of to make way for new stock. PM me if you want a price. We may have a universal module or 2 as well.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.
