Hi All,
I had a strange problem here after upgrading Cisco 3750X.
The upgrading was going smoothly, I copied a newer IOS to the flash from another Cisco 3750X through TFTP, changed the boot image.
It took a while do to the microcode upgrading, finally, it started to boot up. But when it completes the boot up, I can't see the nornal login prompt, but only some strange codes. From what I can see, it seems some decoding problem, as if I plug or unplug a cable from the swich, the strange code pops up again, like in normal situation, the console tells you that the interface is going up and down.
The original image of the switch: c3750e-universalk9-mz.122-53.SE2.bin
Upgrade to image: c3750e-universalk9-mz.122-55.SE3.bin
However, I don't have any problem to telnet to this switch, as it has correct IP address and login configured before the upgrading. I have reboot the switch for couple of times, reconnect to the serial port still doesn't show me anything.
I am wonering has any one has met this situation before? Thanks in advance! Below is the detailed message shown after the boot up.
