Hi. I tried to upgrade software for C2960G-48TC-L from 12.2(35)SE5 to the latest 12.2.50-SE3(ED).
Upgrade was made through web interface from "c2960-lanbasek9-tar.122-50.SE3.tar" file. After all the 4 steps were succesfully finished the switch restarted & now only two orange lamps SYST & RPS are lit :(
P.S. as you certainly understood I'm new to Cisco products & my selfassurance got me into trouble, but I can't even call directly to Cisco, because our service contract ended some time ago & I suppose Cisco forum is the best place to ask in such cases.
Thank God that the network worked not only on that switch, which I "upgraded", so I just plugged users from it to the second one...
