Hello,
I own the Cisco switch,2950-24.
When power on,it says Crash fault with information showed below:
Signal = 10, Code = 0x1C, Uptime 00:00:12

after softreset,I got something similarly
Signal = 10, Code = 0x408, Uptime E

Then I search google.com and found the resolution of upgrating IOS.
I push mode button before power.Then I access into the CLI.I checked the files in the flash: and got these:
switch: dir flash:

22 -rwx 110 <date> info.ver
3246080 bytes available (4495360 bytes used)
switch:
I delete bin,and got these:

I tried kinds of commands.Please give me a hand
08-08-2012 03:19 AM
Console into your switch and post the entire bootup sequence.
I would really like to see where it starts falling apart.

It Stoped here.The bin 12.1(12c)EA1,just softreset twice.
08-08-2012 07:47 PM
It's looks like it's dead but you're getting a "Signal 10" error message which also means an IOS bug. Try uploading a different IOS version.
08-08-2012 07:55 PM
I have tried but it didn't work.Please see my reports below which act as the replies to Alessio.
08-08-2012 04:22 AM
Hi QiNie,
did you try to Xmodem a new IOS in your flash? It takes time but it should work... However i would be worried about the last row:
Cause: 0x0000201C (code 7): Data Bus Error exception
HTH

08-08-2012 07:47 PM
Thank you, Alessio,I have tried this method.I download the BIN,C2950 EI AND SI IOS IMAGE,from here :
I Send the c2950-i6q4l2-mz.121-22.EA14.bin to flash: with Xmodem Protocol,boot from it but failed.And the Crash Fault History said something about Bus error, which just like the old bin done.Then the swith began to softreset from the old bin again and again.....
Is it a hardware problem?
I deleted c2950-i6q4l2-mz.121-22.EA14.bin very easily.But the old bin still con't be removed.
08-08-2012 08:02 PM
Another thing, you need to FORMAT the flash first before you load IOS version EA14 back. If you don't format your flash (via ROMmon), you will not have enough space to put the IOS in.
08-08-2012 08:21 PM
When I attempted to send the EA14 there,I checked the space is very enough.So I put it in and run it then failed.
But format it must can delete the old one.I will do this.
