Re: 3750E boot failure after software upgrade

richard · ‎03-08-2011

Hi,

We have been upgrading our 3750E switches. 3 of the 4 have been fine. The 4th wont boot from the image but will start from the older original image 12.2(44)SE1.

Anyone got any ideas of what I am missing?

Judging from your post it's booting 12.2(55)SE1 with traceback.

Machine Check Exception (0x0200)!

Upgrade the IOS to the 4th switch again. The command should be "archive download-sw /dest 4 tftp:///.tar".

Alternatively, you can plug a USB drive into the USB port with the IOS archive image and use the command "archive download-sw /dest 4 usbflash:///.tar".

In addition to what Leo noted, can you check switch 4 to see if the flash has enough space for the new image?

To give an idea, you can compare the flash size with one of the other switches that is working

Hi Guys,

The image size matches the other switches so I dont think this is a corrupt ios. We did try and download it from various sources but always with the same result on this particular switch. Note that we have successfull upgrade 7 of the 8 units we have to this firmware its just this one thats having the problem.

Cheers

Richard

Hi Richard,

Image size isn't a foolproof way. Get the MD5 and compare the value.
