I have this Cisco fiber switch (catalyst WS-C3750G-12S )and I want to upgrade the iso it has all fiber port and there's no USB port, how can I upgrade the switch only using a console cable 

I have an iso file on my laptop and I already installed tftpd64

Hi

 I am assuming that you dont have any GBIC over there? 

The option I see is via xmodem but, man, this is going to take a while to transfer the IOS. I did it some time ago and it took a long time.

yes I don't have GBIC 

 

 

both Switches  in Stack mode 

can I upgrade the fiber Switch from the Lan Switch using Stack?

It is possible. But, if fiber switch is the master, you need to change it.
