Upgrade IOS & Delete Old BIN Image

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

r0: 00000000, AT: 00000000, v0: 80001800, v1: 00000000

11C 80124338 801C3CFC 801C3CE8

after softreset,I got something similarly

Signal = 10, Code = 0x408, Uptime E

r0: 00000000, AT: 00000000, v0: 00000020, v1: 80730000

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:

Directory of flash:/

2    -rwx  2774747   <date>               c2950-i6q4l2-mz.121-12c.EA1.bin

22   -rwx  110       <date>               info.ver

switch:

I delete bin,and got these:

switch: delete /force flash:/c2950-i6q412-mz.121-12c.EA1.bin

Upgrade IOS & Delete Old BIN Image

Console into your switch and post the entire bootup sequence.

I would really like to see where it starts falling apart.

Upgrade IOS & Delete Old BIN Image

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.

Re: Upgrade IOS & Delete Old BIN Image

I have tried but it didn't work.Please see my reports below which act as the replies to Alessio.

Upgrade IOS & Delete Old BIN Image

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

Re: Upgrade IOS & Delete Old BIN Image

Thank you, Alessio,I have tried this method.I download the BIN,C2950 EI AND SI IOS IMAGE,from here :

http://www.cisco.com/cisco/software/release.html?mdfid=270568146&flowid=2394&softwareid=280805680&release=12.1.22-EA14&relind=AVAILABLE&rellifecycle=ED&reltype=latest

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.

Upgrade IOS & Delete Old BIN Image

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.

Upgrade IOS & Delete Old BIN Image

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.
