Please pardon any stupid questions, I am new to the Juniper prodcuts.
One of our ex4200 switches just disappeared a couple of hours ago and I'm unable to do much with it. I'm afraid it's a hardware issue. All network ports died and console was unresponsive. After a power cycle it starts to boot and repair filesystems. The only complaint is
ext_id_map: not found
until it (usually) makes it down to
Creating initial configuration...
at which point I get
powerpc_mchk_interrupt: machine check interrupt!
*** *** STACK FRAME DUMP ***
U-Boot 1.1.6 (May 19 2010 - 05:03:13)
and the boot process starts over, repairing filesystems etc. The powerpc_mchk_interrupt sometimes appears at different points. I let it boot cycle about 4 times and once it made it to something like "starting additional daemons..." before it threw mchk and cycled again.
I had power removed after that to reduce chances of serious filesystem corruption. This is accessible via remote hands only for power cycling so I need to have my ducks in a row when I call to have it powered up again to be productive. Full log is attached below.
What would my next steps be? I can't find much searching.

See if kb20570 applies to your situation. There is a potential recovery process here.

Thanks. I will read up on this and give it a try. I never saw any errors that resembled the ones the KB article said would require the filesystem repair tool but I doubt it will hurt anything.
