WS-C3750G-48TS upgrade problem

Unanswered Question
May 6th, 2009

Hi ... We recently attempted an upgrade on a 3750G-48TS switch from 12.2(25)SEB1 C3750-IPBASE-M to 12.2(50)SE1 ipservices. The current boot loader is 12.2(25r)SE1.

The upgrade failed with a message of "Loading "flash:c3750-ipservicesk9-mz.122-50.SE1.bin"...flash:c3750-ipservicesk9-mz.122-50.SE1.bin: short read: bad mzip file Error loading "flash:c3750-ipservicesk9-mz.122-50.SE1.bin" "

I verified the image with a "verify /md5" command.

Any idea why this failed? Any help would be appreciated.


I have this problem too.

Perhaps try to download the .tar image from and then upgrade using the "archive download-sw ..." command.
