Need to upgrade IOS on a 3750G-24T stack

Hi,

I'm trying to upgrade the IOS ver on a 3750G stack (2 switches), but the img on the switch is too old.

The stack is running IOS c3750-i9-mz.121-19.EA1d.bin, and when I tried to upgrade to a newer version, I tried to go to IOS ver

c3750-advipservicesk9-mz.122-35.SE5.bin since I need to enable ssh on the switch, but the switch did not reload.

Here's a prtscreen of the switch ver:

Hey Claudia, can I ask how you went about the upgrade?  Did you try copying the .bin file over and set the system boot or did you use the "archive download-sw" command?  Also, is do you need the layer 3 services that are included in the advanced ip services image or can you use the ip base?  If these are just layer 2 switches and you only need SSH then ipbasek9 would work as well.
