Upgrade of Cisco Catalyst 3750G 24T

[nicolastailler]

Hi, 

I want to upgarde a Cisco Catalyst 3750G 24T because I can't see the web interface.

I checked the documentation and see a lot of videos on the net.

I downloaded the new firmware c3750-ipbasek9-mz.122-55.SE9.bin

I downloaded a tftp software and putted my ip adress on it.

I connected the Cisco by console and launched Putty by serial.

I sended en for grant my right access.

I sended my password

and tapped :

copy tftp: flash:
it asks TFTP Ip, i gave it
10.0.0.45

file name

i gave it 
c3750-ipbasek9-mz.122-55.SE9.bin
 

and after It sended me when it must put it and i sended the same name.
c3750-ipbasek9-mz.122-55.SE9.bin

And then It works few seconds and the cisco says error ... time out.

I've tested with W8, W7 and a lot of tftp server. I disabled my firewall.

The password is the default password. It is a problem ?

Can you help me ?

Thanks

Nicolas

Did you confirm you can ping 10.0.0.45 from your switch to your PC with ftp server?

Also, if your PC has a second network connection (like wireless) you should try to disable it because the ftp server may bind to the wrong interface.
