switch:
switch:
switch: copy xmodem: flash:c2960-lanbase-mz.122-35.SE5.bin
Begin the Xmodem or Xmodem-1K transfer now...

try this:
nb. the boot command previously doesn't have a colon: after it. (Just in case you want to try it again). I know it isn't supposed to have an IOs on it, but the set command says it does...

Hi,
Make sure there's no IOS with the dir flash: command. If you find one, use the boot flash:
I believe on the 2960 switches, you can use the USB interface to connect a pendrive and load an IOS from there. It will be device named usb: I guess.
If there's no IOS and no USB available, you need to follow the below documentation to recover from this situation:

If you type "set" at the switch: prompt, do you get anything?
switch: set
?
Otherwise it could just be the flash is corrupt.

OK. So you might not have space on the flash.
What happen if you type boot c2960-lanbasek9-mz.122-46.SE.bin
?
ā05-04-2011 10:35 AM
switch: boot:c2960-lanbasek9-mz.122-46.SE.bin
Unknown cmd: boot:c2960-lanbasek9-mz.122-46.SE.bin

Thank youuu so muchhhh!!!! it works fine. These parts were the keys. It almost simultaneous...
The next example shows an Xmodem procedure on a 2955 with the use of HyperTerminal. The procedure is the same for any of the Catalyst fixed configuration switches that this document covers.
Issue the copy xmodem: flash:filename command on the switch.
Here is an example:
switch: copy xmodem: flash:c2955-i6q4l2-mz.121-13.EA1.bin Begin the Xmodem or Xmodem-1K transfer now... CCC
From the top of the HyperTerminal window, choose Transfer > Send File.
