I have a Catalyst 2820 (WS-C2822) for my studies, without a valid firmware. I've downloaded v9.00.34 from Cisco, however no terminal software I use would upload it to the switch (or the switch would not accept it).
I tried all possible baud rates (9600 & 57600), and various sw (Hyperterm, TeraTerm), different PCs, different Com ports... All I get is either a timeout or Xmodem errors.
The Switch's Boot firmware version is 2.04
Any help would be really appreciated...
