3945E in a crashloop

Grant Bagdasarian · ‎03-14-2012

Hello,

I have an urgent matter. Our 3945E keeps crashing on bootup. The reason is that it tries to load up a script each time it boots, which causes it to crash. Its a TCL script which uses a timer. This is the error:

10:34:19 CET Wed Mar 14 2012: Unexpected exception to CPU: vector D, PC = 0x2BAAFB5

No warm reboot Storage

How would I fix this?

Thanks,

Never mind, I managed to fix it using the rommon mode and confreg 0x2142 to ignore the NVRAM. After it booted up with a clean config I deleted the tcl script from the flash and rebooted back with confreg 0x102. Now my initial config is back but the device doesnt crash anymore since it cant find the file on the flash.
