problems on octane random shut downs

Unread postby soviet » Mon Aug 13, 2012 8:37 am

Hello i have a octane 1, and having random power downs problems, and also some times i can't power it up i have to move the octane around or lift it 5 cm drop it and then push the power button and the system start ok.
Sometimes i can work for hours whit no problems, but at random the system start the shut down procedure and display a XIO error on the console before shut down.

How can i fix this ?.

If moving it around or bouncing it seems to fix it, sounds like "something" is "loose."

If it isn't something loose then the next suspect is probably the frontplane board (FP1) - the power button does show up as an XIO widget, and a failure somewhere there would definitely start a shutdown.

The main circuitry on the FP1 is the XBOW ASIC, but the board still might be worth checking it out because it does sound like something mechanical, and it might be the switch or a trace.

That's some fine debugging to track something like that down, nice going... :mrgreen:
