3750 boots ... kinda

I have a 3450G running ipservicesk9-mz.122-50.SE1. This switch had been up for years. I unracked it this morning and fired it up. It comes up and loads the IOS (abbreviated):

So what this ended up being was right where I indicated in the output stopped:

Switch Ports Model              SW Version            SW Image

------ ----- -----              ----------            ----------

*    1 52    WS-C3750G-48TS     12.2(50)SE1           C3750-IPSERVICESK9-M

¸C

The switch changed the baud rate to 115000. Before that I was using 9600 like always and could see all the output but when it got to the ,C it changed. So, once I changed my baud rate to 115000 I was in.

Re: 3750 boots ... kinda

You can try to isolate the issue.... Try to switch# mode the switch rename the configuration. Then restart.

If it is still not working try to reupload the iOS or try dif. Version but before you upload try to reformat the flash
