Hi Antonio,
Are looking for copy the IOS to the Switch flash? or do you want to backup the IOS image from the switch?
Best regards.

Hi Antonio,
Unfortunately switches does not have rommon to realize quick IOS recovery over tftp. Only one way is over Xmodem. The process is the following:
To speed up the process of the recovery we may setup Xmodem speed to higher rate as default 9600 bits:
Set the speed rate to 115200 baud on the switch prompt of the switch:
switch: set BAUD 115200
Of course you lose your console session and therefore you need to restart it with the correct speed settings. Then you may realize the recovery.
Enter copy command:
copy xmodem: flash:filename
for example for Cat2960-24TTL:
switch:copy xmodem: flash:c2960-lanbasek9-mz.122-52.SE.bin
Begin the Xmodem or Xmodem-1K transfer now...
CCC
And start sending of the file over console Xmodem software.
Recovery over HyperTerminal
Choose Transfer > Send File.
And then you choose as protocol the Xmodem and in filename click Browse and select the Cisco IOS image (.bin file) from the disk to be uploaded.
and click Send to send the file,
After the image was uploaded you need to boot the new image that you just copied over with the Xmodem procedure issue the boot flash:filename command, as the example shows:
switch: boot flash:c2960-lanbasek9-mz.122-52.SE.bin
After the Xmodem recovery, we set the BAUD rate back to 9600. If the set BAUD 9600 command does not bring the baud rate to 9600, issue the unset BAUD command in order to bring the baud rate to a default value of 9600 bps.
If it was useful please rate.
Best regards.

You will need download the IOS image from Cisco Support, if the switch is new you can ask it to the Cisco TAC otherwise you have to acquired an SMARTnet.
Regards.
