Upgrading an IOS on SW 2960

[Julio E. Moisa]

I found a corrupt IOS, The switch is not booting properly. When i try to upgrade using XMODEM appears the following error:

switch:

switch:

switch: copy xmodem: flash:c2960-lanbase-mz.122-35.SE5.bin
Begin the Xmodem or Xmodem-1K transfer now...
CCCCCCCCCC           BB0BB0xmodem:: I/O error

Someone has a solution?

Thank you.

If you type "set" at the switch: prompt, do you get anything?

switch: set

?

Otherwise it could just be the flash is corrupt.

Thank you

I got the following information:

switch: set

OK. So you might not have space on the flash.

What happen if you type boot c2960-lanbasek9-mz.122-46.SE.bin

?

[Julio E. Moisa]

switch: boot:c2960-lanbasek9-mz.122-46.SE.bin
Unknown cmd: boot:c2960-lanbasek9-mz.122-46.SE.bin

There are not any IOS on the switch

[Julio E. Moisa]

how i can upgrade the IOS on this mode?

try this:

http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_25_see/configuration/guide/swtrbl.html

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: command to boot it.

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:

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.

1. 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

2. From the top of the HyperTerminal window, choose Transfer > Send File.
