I am working with a Catalyst 2950 switch, and somehow there is nothing on in the Flash memory for it to boot from. I downloaded the image onto my computer, but now i have no idea how to get it from the PC to the switch, without having the switch booted up. Help please?

Well, I'm on a 2950 Switch, so everytime I type in one letter, it goes to the next line, and I cant even type a command. I can't get into rommon, but I can get into just "rom" and that's where it types one letter then goes to the next line.

You have a console port speed mismatch


Make sure you are resetting your terminal emulation software to match the default baudrate i.e. 9600.


If this is a new switch that you are not sure what the baud rate might be, you will have to try some combinations (from 9600 to 1152000) to get the correct output.

It's on 9600 and when it starts, it doesn't boot up, it goes to a thing where it says "switch:" and you can type in commands, but not normal commands. And I can read everything it says. I can't get an actual rommon, but i can type in "trap" and it comes up saying "rom" and thats when I get what was previously stated

Someone might have changed the rommon setting and inadvertently changed the baud rate while typing in the wrong confreg value.


You can try more values (higher than 9600) and see if it comes up properly.


Unfortunately I dont think this switch comes with an aux port (do you see one?) or you could try plugging it in the aux and try bringing it up.


If this is a non functional console port and you are positive the baud is correct, Id raise a tac to have an RMA executed.
