Adding to the useful link posted by JVOSS2... As noted in the posted link, there are some different syntax's in use (mostly backwards compatible) between versions of CNOS 10.6 and older, and CNOS 10.7 and newer. I'm attaching a PDF that covers upgrading any ENOS or CNOS based switch of any version (including using the USB port if available on the switch). Specific to your case, if the switches are currently running 10.7.x.x or newer, look at page 3. And if the switches are running 10.1.x.x to 10.6.x.x or older, look at page 4.

 

Also, if you are upgrading a VLAGed pair of Lenovo switches and want to minimize issues and downtime, see pages 9 and 10 of the attached.

 

Hope this helps

 

Thanks, Matt
